In these difficult times, we are all searching for ways to take more care of ourselves. Research is constantly being updated on the benefits of CBD and to what extent it can boost our mental and physical health. Studies have found that CBD may help to maintain an active lifestyle by managing pain and reducing inflammation. In addition, it may reduce the stress caused by anxiety and depression. PureSport CBD uses natural ingredients that work in harmony with your body. CBD for health and fitness has much to offer and it’s no surprise that CBD products are becoming more popular.
An Introduction To CBD
What Is CBD?
CBD is derived from the plant cannabis sativa. It is a non-toxic, natural compound with no psychoactive properties. CBD for health and fitness may have many benefits, both for physical well-being and mental health. Research suggests that it may have anti-inflammatory properties and might work as a natural alternative to more traditional painkillers, such as ibuprofen. Indeed, CBD is beginning to gain a reputation as a way of relieving a variety of ailments.
What Does CBD Mean?
CBD is an abbreviation of the word cannabidiol. First discovered in the 1940s, CBD is one of over a hundred identified chemicals in the cannabis plant. CBD is an extract from the leaves, flowers and stalk of the hemp plant.
Is CBD THC Free?
THC is short for tetrahydrocannabinol. It is one of the cannabinoids found in cannabis and is the psychoactive element of the plant. Taken from the hemp plant, CBD contains a tiny amount of THC. It is treated to remove all the psychoactive substances and tested in a laboratory to ensure that it contains 0% THC. PureSport’s CBD undergoes thorough testing to guarantee that PureSport CBD is both safe and legal to use.
What’s The Difference Between Cannabis And Hemp?
In botanical terms, cannabis and hemp plants belong to the same family, cannabaceae. The difference is in their composition. Both plants contain CBD and THC, which is the psychoactive element in cannabis. The hemp plant has more CBD and contains just a trace of THC. To be classified as hemp, the percentage of THC must be 0.3% or lower. An additional 0.1% of THC would mean that the plant is deemed to be marijuana. The hemp plant is used to extract CBD, as it contains a larger amount of CBD and minimal THC.
What Is MCT Oil?
Where Does MCT Oil Come From?
MCTs are fatty acids found in dairy products and known as medium-chain triglycerides. Palm kernel and coconut oil are used to extract the majority of MCT oil. In fact, up to half of the fats in coconut oil are MCTs.
What Does MCT Oil Do?
By adding MCT oil to CBD products, many users have found that they have benefited from:
- Enhanced brain function, including memory
- A boost to energy and increased endurance
- Lower blood sugar and cholesterol levels
- Weight loss and improved weight management.
The body absorbs MCT oil to convert it into energy. MCTs become ketones, which the body produces as it burns fat for energy if low in carbohydrates. If following a ketogenic diet, which is low in carbohydrates but high in fat, MCT oil should prolong the fat-burning state. It is a great way to give your energy a boost during exercise and may provide an additional source of fuel for the brain.
How Do I Use MCT Oil?
MCT oil is a versatile product and can be:
- Mixed with tea or coffee
- Added to smoothies
- Used with salad dressings or sauces
- Drizzled on a meal.
PureSport CBD Oil Tincture combines CBD with MCT oil. Made from natural ingredients, the tincture may encourage the body to be three times more effective at producing ketones.
CBD In The Body
How Does CBD Work In The Body?
The body’s endocannabinoid system, or ECS, is a molecular system, which is involved in many of the body’s functions. In fact, the ECS is one of the most important systems in the body for maintaining overall good health. Endocannabinoids and receptors exist throughout the body. It is believed that CBD works by interacting with the ECS to stimulate the receptors into producing their own cannabinoids. Studies suggest that CBD may delay the breakdown of the endocannabinoids, to ensure that they spend more time in the body.
What Could CBD Do For You?
Research indicates that CBD works in harmony with the body. It could influence a variety of elements such as immunity, emotion, anxiety, sleep and pain. In this way, CBD for health and fitness may offer a range of benefits for both physical and mental health and well-being. It should be noted, however, that research is constantly ongoing and advice on CBD is being updated all the time.
CBD For Health And Fitness
Studies suggest that CBD could have a number of health benefits and many people are turning to it as a form of natural healing. CBD may be able to:
- Provide natural pain relief – whether muscular, joint or chronic pain
- Reduce inflammation
- Aid relaxation
- Reduce symptoms from stress and anxiety
- Improve quality of sleep.
PureSport CBD has a range of CBD products available, made from natural ingredients and suitable for vegans and vegetarians.
CBD For Athletes
Research shows that CBD might help you to manage and improve your health and well-being in both body and mind. PureSport CBD for health and fitness uses natural ingredients that work together with your body. Make it part of your routine every day for overall good health.
CBD For Stamina
If you need to increase your stamina, research suggests that CBD might give you a boost, to reinvigorate both your mind and body. It is believed that CBD interacts with the body’s internal receptors. Using CBD for stamina could make you feel more active and alert. Users of CBD may experience an increase in energy levels and greater clarity of thought. Whatever your level of performance, to get the most out of your workout and training you will want to be at your highest level. If your energy levels dip, CBD might improve your stamina. PureSport CBD oil tincture contains added MCT oil, which studies show could boost your body’s endurance.
CBD For Recovery
More and more athletes are turning to CBD for health and fitness to relieve sore or injured muscles.
CBD For Injury Recovery
Many users have found that CBD may reduce both muscle inflammation and relieve pain to speed up the body’s recovery from injury.
How Can I Relieve Muscle Soreness?
By working harder, muscle fibres rip and this causes them to become sore. To relieve muscle soreness, try:
- Light stretching or massaging the sore muscles
- Having a rest
- Ice to reduce inflammation
- Heat to increase the blood flow to the muscles
- Taking pain relief medicine.
CBD For Inflammation – How does it work?
Muscles become inflamed by injuries and release chemicals to increase blood flow to help them to recover. However, inflammation spreads to nearby tissue and slows the healing process. There is evidence to suggest that using CBD for inflammation should treat the injury directly without damaging the surrounding area.
CBD For Rest And Relaxation
An important part of recovery is to make sure that you have plenty of rest. While sleeping, the brain releases hormones to target damaged muscles. Encouraging the body to relax and sleep better should help tired or injured muscles to heal. PureSport Muscle and Joint Balm targets aching joints and muscles and may relieve pain to speed up recovery. Made from natural ingredients, it contains 0% THC. Apply the balm straight onto the injured part of the body. It complements PureSport CBD oils and capsules.
CBD For Pain Relief
Research suggests that CBD for health and fitness may offer pain relief by interacting with the body’s endocannabinoid system, or ECS. The ECS is a molecular system used by the body for maintaining its internal balance. It is believed that, by stimulating the body’s receptors, CBD could help to restore stability, decrease inflammation and reduce pain. As a natural pain reliever, CBD may target specific problem areas to help to speed up recovery. Users have found that it can soothe aching muscles after a tough session in the gym and help the return to full fitness. PureSport’s Muscle and Joint Balm targets tired muscles and joints to treat your aches and pains. Natural ingredients, such as lavender and peppermint, are combined to create a balm that may help with pain relief and relaxation.
CBD For Mental Health
Being a successful athlete relies on a combination of physical stamina and mental strength. Research indicates that using CBD for health and fitness might reduce the symptoms of stress and anxiety. It could help you to achieve your best without letting your overwhelming emotions hold you back. Users have found that CBD may help your body to relax and improve the quality of your sleep. This will reduce stress and aid your recovery from the aches and pains of physical activity. CBD for mental health could help you to manage your emotions and anxieties. Made with natural ingredients, PureSport’s CBD and oils should work in harmony with your body. It is believed that they could encourage self-healing and restore your inner balance.
CBD For Health
It is important to maintain a healthy and active lifestyle throughout life. Stay active to:
- reduce the risk of developing certain types of cancer
- lower your chances of a heart attack or stroke
- strengthen bones, muscles and joints
- lower blood cholesterol and blood pressure
- manage weight
CBD for health and fitness may have many benefits to help you look after yourself and stay healthy. There is evidence to suggest that CBD might offer relief from many health issues, both physical and mental. It may work in harmony with your body to encourage inner healing and restore balance. PureSport CBD capsules use natural ingredients, such as turmeric, which has many health benefits, MCT oil and ginger. Used daily as part of a healthy routine, they may help you to improve health and well-being.
CBD For Physical Health
CBD For Immunity
To help the body’s fight against infection, studies suggest that using CBD for immunity may encourage good health and well-being.
What’s The Immune System?
Every cell and tissue in the body form part of the immune system. In addition, skin and saliva provide an outer barrier to infection. A healthy immune system is vital to protect us from viruses, such as colds and flu.
How Can I Improve My Immune System?
Small changes to diet and lifestyle can strengthen the immune system, such as:
- Managing stress
- Taking regular exercise
- Reducing sugar intake
- Drinking plenty of water
- Getting a good night’s sleep.
How Might CBD Help The Immune System?
There is some evidence to support the fact that CBD could boost your immune system and encourage it to become more efficient. If used for an extended time, studies suggest that CBD may help to build up immunity. It might also provide relief for some autoimmune conditions that attack the body’s own tissue. Although there is still much to learn, CBD may offer a safe and healthy way in which to benefit your body.
CBD For Muscle Spasms
What’s A Muscle Spasm?
If a muscle contracts but is unable to relax, it may lead to a spasm. This can occur from fatigue due to overuse or through dehydration. Over-clenching muscles can also lead to a spasm. Muscle spasms or cramps can happen without warning and be a short but painful experience. There is some evidence to suggest that using CBD for muscle spasms may help to relieve the discomfort and pain they can cause.
How Can I Relieve Pain From Muscle Spasms?
There are several ways to relieve the pain from muscle spasms:
- Stretching out the muscle
- Applying ice or heat to the area
- Drinking water
- Having a massage
- Doing low intensity exercise.
Studies show that CBD for muscle spasms could help to release tension in tired muscles. Users have found that it may help the muscles to relax by reducing inflammation and giving pain relief from soreness.
CBD For Chronic Pain
Evidence suggests that using CBD for chronic pain might reduce inflammation and pain associated with some long-term health conditions.
CBD For Arthritic Pain
Arthritis can affect people of any age, including children. A common condition, arthritis causes stiffness, swelling and pain in one or more joints of the body. There are many types of arthritis and it is important to get a correct diagnosis. Although there is no cure, taking exercise or having physiotherapy can help to manage arthritic pain.
Research suggests that CBD could interact with the body’s immune system, as it may have anti-inflammatory properties and natural pain relief. CBD oil may help to manage the chronic pain associated with certain types of inflammatory arthritis, such as rheumatoid arthritis. PureSport’s CBD capsules contain turmeric, ginger and black pepper. The combination of these natural ingredients may ease the pain associated with arthritis.
CBD For Inflammatory Pain
Inflammation is the way in which the body protects us from foreign organisms. The white blood cells in the body and the substances they produce, help us to fight off viruses and bacteria.
How Can I Relieve Pain From Inflammation?
If inflammation leads to pain, there are several steps that can be taken to relieve the symptoms, such as:
- Taking more exercise
- Losing weight
- Managing stress
- Reducing intake of inflammatory foods.
CBD For Inflammation
Inflammation can be caused by injuries, infections or even long-term exposure to irritants, such as chemicals or pollution. Research suggests that CBD may have anti-inflammatory properties, which could reduce inflammatory pain. It is believed that it interacts with the body’s endocannabinoid system (ECS), which carries neurotransmitters found in the nervous system. CBD may react with the cannabinoid receptors in the ECS to reduce inflammation.
CBD For Autoimmune Issues
Inflammation in the body can occur as a result of certain types of autoimmune conditions. These are diseases that can stop the immune system from recognising the body’s own cells. It will attack joints and skin cells as if they were foreign invaders. The most common autoimmune diseases are inflammatory bowel disease, ulcerative colitis and rheumatoid arthritis. Currently, these conditions cannot be cured. There is evidence, however, to suggest that in some cases CBD could relieve inflammation and pain to ease the symptoms.
CBD For Nerve Related Pain
Nerve related pain happens if a nerve carrying sensations to the brain becomes damaged. Surgery or trauma can cause nerve damage. Conditions such as multiple sclerosis can be a cause of nerve pain. Poor posture and an increase in stress levels can be a contributory factor. Natural ways of coping with nerve pain include:
- Trying to relax and stay calm
- Getting more rest and sleep
- Taking more exercise
Users have found that CBD may help muscles to relax by reducing the pressure on nerves. Studies suggest that the anti-inflammatory properties and natural pain relief of CBD could aid sleep and lower anxiety.
CBD For Weight Loss
By reacting with cannabinoid receptors in the body, research suggests that CBD could help with weight loss. The receptors form part of the endocannabinoid system (ECS) and can influence several processes in the body, including appetite. Evidence suggests that CBD may close off cannabinoid receptors without deactivating them. Blocking off the receptors should help to reduce the appetite.
Turmeric For Digestive Problems
A relative of ginger, turmeric may be taken to help with issues related to the stomach, such as metabolic disorders and obesity. Studies have shown that turmeric may act as an antioxidant and possess anti-inflammatory properties. It may be able to reduce the inflammation that can develop from obesity and help to boost weight loss. Excessive doses of turmeric should be avoided, as it may lead to side effects, such as an increased risk of kidney stones. PureSport’s CBD capsules combine turmeric and ginger with black pepper. They are a great way to enjoy the benefits from these natural ingredients.
CBD For The Heart
Research has shown that CBD may benefit the heart and blood circulation. High blood pressure can lead to diseases such as heart attacks and strokes. If you are suffering from high blood pressure, there are several steps you can take to reduce it, such as:
- Weight loss
- Regular exercise
- Healthy eating
- Not smoking
- Lower alcohol consumption
- Reducing stress.
Studies suggest that CBD has anti-inflammatory properties and may reduce the feelings of stress and anxiety. This can, in turn, help to lower high blood pressure. CBD may be able to benefit the heart by reducing the risk factors of illnesses related to high blood pressure.
CBD For Skin Health
The skin is the body’s largest organ by size and prevents germs from entering the body to attack the internal organs. It helps to maintain the body’s immune system and regulate body temperature.
CBD For Skin
Users have found that CBD for skin health could have many benefits to keep skin healthy and may offer relief from various skin conditions. Studies suggest that CBD may help to improve sleep quality. CBD may benefit healthy skin, as skin health can improve over time from regularly experiencing a good night’s sleep. CBD may help your body to relax and therefore help you to sleep better. This should improve the look and feel of your skin.
CBD For Acne
Research suggests that one of the benefits of CBD for acne, is that it can influence the body’s creation of sebum. Sebum is a natural, oily substance that the body produces to keep skin moisturised and protected. If the body makes more sebum than it needs, the skin can become oily and conditions such as acne can develop. Studies show that by preventing the body from overproducing sebum, CBD may help to reduce the effects of acne and other similar skin problems.
CBD For Skin Scars
If used as an ointment, it is believed that CBD might bind to the skin’s own endocannabinoid system to provide many benefits. Users may find it reduces the visibility of scarring from acne, fine lines and wrinkles.
CBD For Dry Skin
If skin is dry and flaky, studies indicate that applying CBD oils to the affected area could add moisture to heal broken skin. Research suggests that CBD may reduce inflammation to relieve any soreness from patchy skin. This would help with the treatment of skin conditions such as psoriasis and eczema.
CBD For Sleep
What Are The Benefits Of Sleep?
Something like a quarter of people in the UK suffer from poor quality sleep. A good night’s sleep is vital for maintaining health and well-being. Sleep has many benefits, including:
- Reducing the risk of heart attacks and strokes
- Lowering blood pressure
- Keeping cholesterol levels under control
- Reducing feelings of stress and anxiety.
How Can I Get A Good Night’s Sleep?
Stress and anxiety are a common cause of insomnia and a lack of sleep can make the symptoms worse. There are steps you can take to try to ensure that you get a good night’s sleep:
- Try to go to bed and wake up at consistent times
- Avoid drinking caffeine late in the day
- Don’t eat or drink too soon before going to bed
- Reduce intake of alcohol and nicotine
- Limit exposure to blue light just before going to bed.
Tests suggest that CBD might help if you are suffering from insomnia and want to try a natural way to improve your sleep. By helping your body to relax, CBD may allow you to enjoy a better night’s sleep.
CBD For Nausea And Vomiting
How Can I Get Relief From Nausea And Vomiting?
Studies show the possible benefit of taking CBD for nausea and vomiting. It may help with the symptoms, including those that occur from certain types of cancer treatment. Try the following to see if they can relieve nausea and vomiting:
- Anti-nausea medicine
- A cold drink
- Peppermint tea or sweets
- Plenty of fresh air.
How Does CBD Help With Nausea And Vomiting?
If taken in small doses, research indicates that CBD might help with the nausea and vomiting that results from some cancer treatments. CBD is believed to interact with receptors in the body that release serotonin. Serotonin is a chemical that is responsible for regulating many things in the body, including moods. It promotes a natural way to soothe the body. CBD may act as a natural alternative for the relief of symptoms and pain associated with cancer. As CBD could ease anxiety, it may help sufferers manage the stress of chronic sickness. It is worth noting that clinical research is still being undertaken on the benefits of CBD for nausea and vomiting.
CBD For IBS
What Is IBS?
IBS (irritable bowel syndrome) is a disorder that affects the intestines and can cause discomfort and pain. Studies have suggested that taking CBD for IBS may help to reduce the symptoms. IBS can develop from a virus or bacteria in the digestive system. The addition of stress and anxiety may be a factor in developing the symptoms. A lack of endocannabinoids in the body may also contribute to IBS.
What Are The Symptoms Of IBS?
Symptoms of IBS can include irregular bowel movements, frequent abdominal pain, stomach cramps and bloating.
How Can I Relieve The Symptoms Of IBS?
There is no cure for IBS but to lessen symptoms try:
- Making lifestyle changes
- Modifying your diet
- Peppermint oil (may ease the pain from muscle spasms)
- Ginger (believed to settle your stomach and reduce nausea)
- Turmeric (may reduce inflammation).
How Does CBD Help With IBS?
Research suggests that CBD may help to relieve some symptoms of IBS. It may increase the natural levels of endocannabinoids in order to stabilise the body’s endocannabinoid system. To reduce inflammation and provide pain relief, users may combine CBD with an anti-inflammatory diet. In addition, taking CBD for IBS may reduce bloating and the associated discomfort. Turmeric, ginger and black pepper are combined to create PureSport’s CBD capsules. These offer a natural way to reduce inflammation, soothe the symptoms of IBS and are guaranteed to contain 0% THC.
CBD For Epilepsy
What Is Epilepsy?
Epilepsy is a common neurological condition, which can happen without warning. It may result in convulsions or a loss of consciousness. Epilepsy is an inherited condition but may also be triggered by an infection or trauma to the brain. Something like one in a hundred people will have a seizure in their lifetime. A number of them may go on to develop epilepsy. Ongoing studies indicate that trying CBD for epilepsy may help to reduce the effects experienced when having a seizure.
How Might CBD Help Epilepsy?
Research suggests that CBD may help to improve some symptoms of chronic seizures experienced by those with epilepsy, such as muscle spasms. Inflammation can cause muscles to spasm and this can prove to be painful. Using CBD for epilepsy may reduce the inflammation that causes muscle spasms.
CBD For Neurological Disorders
Studies have shown that CBD may benefit those with neurological disorders, such as Parkinson’s disease. Neurological disorders occur in the brain and nervous system. It is believed that CBD may provide some relief from the tremors associated with Parkinson’s disease. It may be used to treat the psychosis suffered by those with Parkinson’s disease dementia.
What Is REM Behaviour Disorder?
REM behaviour disorder may be experienced by sufferers of Parkinson’s disease. REM (rapid eye movement) is the time in sleep when dreaming occurs. It takes its name from the movement of the eyes during that part of sleep. Under normal circumstances, the body’s movements will diminish in REM sleep. In REM behaviour disorder, the body is able to move and the person suffering from this may act out their dreams. This can lead to disturbed sleep and, in some cases, self-injury or harm to a partner.
How Does CBD Help With Neurological Disorders?
There is evidence to suggest that the calming and relaxing nature of CBD may give sufferers a better night’s sleep. This may then help to ease the effects of neurological disorders.
CBD For Mental Health
CBD For Stress And Anxiety
What Causes Stress And Anxiety?
A considerable percentage of the population will experience feelings of stress and anxiety at some point in their lives. It could be triggered by a single traumatic event or a build up of issues over time. Examples of the causes of stress and anxiety are:
- Losing a loved one
- Going through a divorce
- Work related problems
- Moving home
- Being diagnosed with an illness or condition
- Emotional issues, such as depression or low self-esteem.
What Happens To The Body When You Are Stressed?
The body releases hormones, such as adrenaline, if you experience stress. These hormones increase blood pressure and heart rate to help your body react quicker to an exciting or stressful situation. Should these feelings continue for an extended time, they may become debilitating.
What Are The Symptoms Of Stress And Anxiety?
The symptoms of stress and anxiety will vary from person to person and can include:
- Lack of sleep
- Muscular aches and pains.
What Are The Effects Of Stress?
The emotional effects of stress and anxiety can be overwhelming:
- Lack of motivation or interest
- Poor levels of concentration
- Feeling angry or irritable.
CBD For Stress And Anxiety
Studies suggest that using CBD for stress and anxiety could offer a natural way to reduce the symptoms. It may encourage your body to relax and ensure that you have a better night’s sleep. Research has shown that CBD may work by influencing the way that the brain’s receptors react to serotonin. A chemical with several functions, serotonin is important for regulating the mood. The calming and soothing effects of CBD might:
- Provide stress relief
- Encourage feelings of calm, such as lowering heart rate
- Reduce insomnia.
There may be times in a busy life when you struggle to cope with stress and anxiety. Studies show that CBD could reduce the symptoms and work with your body to restore your inner balance.
CBD For Post Traumatic Stress Disorder (PTSD)
Post Traumatic Stress Disorder (PTSD) may occur after experiencing or witnessing a traumatic event. Its effects might last for many years and impact on daily life. Symptoms of PTSD include nightmares and flashbacks, feelings of anxiety and disturbed sleep. Therapy or antidepressants are offered as a treatment for PTSD. There is some evidence to show that CBD may interact with the body to encourage better quality sleep and help to stop traumatic memories. By promoting both physical and mental well-being, studies found that CBD may help PTSD sufferers begin to make a recovery.
CBD For Depression
Something like 1 in 4 people every year will experience a problem with their mental health in the UK. There has been an increase in the number of people suffering with depression over recent years.
What Causes Depression?
There can be many causes of depression and these may combine to make a person feel more vulnerable. A traumatic life event, medication or health issues could all contribute. For some, it can be an inherited condition. Symptoms of depression include feelings of low self-esteem, hopelessness and a continual low mood.
What Does CBD Do For Depression?
Research suggests that CBD might help with the symptoms of depression. It is believed that CBD interacts with receptors in the brain to reduce the feelings of stress. It may help with relaxation and sleep disorders, such as insomnia.
CBD For ADHD
Attention deficit hyperactivity disorder, or ADHD, affects something like 2% – 5% of children. The condition can affect 3% – 4% of adults and many of these go undiagnosed. It is unclear what causes ADHD but it might be an inherited disorder. Symptoms of ADHD include having a short attention span, fidgeting and acting without thinking. There is no cure but treatment is available through medicine and therapy. Research suggests that sufferers who experience bouts of anxiety might benefit from taking CBD oil. Although it is unable to provide a cure, there is some evidence to show that CBD might help with managing the symptoms of ADHD.
CBD For Substance Addiction
Cannabis becomes addictive because of the presence of Tetrahydrocannabinol, or THC, taken from the cannabis plant. CBD is a compound extracted from the hemp plant, which contains only a minimal amount of THC and has no addictive or psychoactive properties. In fact, research suggests that CBD might help to reduce the anxiety and cravings associated with addiction. PureSport’s CBD undergoes thorough laboratory testing to ensure that it contains 0% THC. Our CBD is safe to use, without the risk of leading to addiction.
Possible Side Effects Of CBD
Some users may experience side effects from using CBD oil:
- A dry mouth, as cannabinoids may inhibit the production of saliva
- Low blood pressure, which might lead to some dizziness or drowsiness
- Diarrhoea and/or vomiting
- A reaction from taking other medications, such as blood thinning medicine.
If you experience severe side effects, you should consult your GP.
CBD For Health And Fitness
Research is continually being undertaken into CBD and its healing potential for health and fitness. More in-depth clinical trials will certainly be needed but findings so far have proved to be encouraging. Many factors may influence the effectiveness of CBD, such as an individual’s health or the strength and quality of the CBD product. There is still a long way to go before we can understand the full potential of CBD.
