Supplements to support everyday energy and vitality. Ideal for busy lifestyles, vegetarians and vegans
Vitamin B12 (also known as cobalamin) supports numerous bodily functions, including the brain and red blood cell production. However, as the body doesn't produce vitamin B12 naturally, people need to get their recommended intake through diet or supplements.
If you don't get enough vitamin B12 through diet alone, supplements can nourish your body and help you avoid the effects of a deficiency.
Sealions is fully committed to offering value for money without compromising on quality. Costing just £5.00 for a year's supply, you can prioritise your health and look forward to excellent savings.
Why does the body need Vitamin B12?
As an essential vitamin to ensure normal bodily functions, if you suffer with a deficiency you'll feel the effects. Various food sources contain B12, including:
- Trout and salmon
- Liver and beef
- Dairy products
- Plant-based milk
- Fortified breakfast cereals
Consuming a vegetarian or vegan diet can make you particularly susceptible to a deficiency as the foods that contain vitamin B12 are limited.
However, some people are naturally at risk of developing a deficiency due to certain conditions and lifestyle choices, including:
- Failing to consume a balanced diet
- People with Type 1 diabetes
- Chron's disease
- Inherited deficiency from family members
- Older adults
The effects of Vitamin B12 deficiency
People with low levels of B12 may experience a range of side effects that make it hard to function and perform daily activities. Some people's symptoms might be minor, while others can experience side effects that could impact their ability to work.
Fatigue and weakness
Some people with low vitamin B12 levels feel tired all the time and experience weakness when performing daily activities. If things like climbing the stairs make you feel faint, or you struggle to stay awake throughout the day, it could be a sign that your levels are low.
Vitamin B12 is instrumental in producing red blood cells, and a deficiency often leads to megaloblastic anaemia, causing weakness, pale skin and shortness of breath. If you have this condition you could require regular B12 injections and folic acid supplements.
Numbness or tingling
Some people with the deficiency develop neuropathy, which can cause a tingling sensation in the extremities. The side effects of neuropathy include numbness, weakness and problems when trying to balance.
Cognitive issues like memory loss, difficulty concentrating, and mental fogginess are also associated with a B12 deficiency. Older adults with low levels of B12 may be misdiagnosed with dementia, highlighting how severe a deficit can get if left untreated.
B12 deficiency is also known to affect your mood, leading to irritability, a lack of motivation, feeling overwhelmed, and even developing depressive symptoms. In the most severe cases, people can also experience psychosis.
The benefits of taking Vitamin B12 tablets
If you're worried you don't get enough vitamin B12 from diet alone, adding a daily supplement could positively affect your overall health and state of mind.
Here are the main benefits of taking our B12 tablets:
Vitamin B12 is crucial in converting food into energy, helping the body metabolise fats and carbohydrates. However, when this function doesn't work properly, your body could struggle to utilise food sources, making you feel weak and tired.
Giving your body a daily dose of this vitamin can give you more energy and reduce the effects of weakness from general activities.
The brain is the body's most complex organ, and studies have proven that low levels of vitamin B12 can have a negative effect on how the brain and nervous system function (NCBI). Taking a supplement can enhance cognitive function and reduce the risk factors for neurological disorders.
You can also boost the production of myelin by increasing your B12 intake. Myelin forms a protective sheath around the cells, preventing nerve damage.
Red blood cell formation
B12 is vital for the production of red blood cells. Without it, the cells risk becoming enlarged, and they won't be able to carry as much oxygen around the body. Megaloblastic anaemia is treatable, especially if you act early.
Taking B12 tablets can help prevent and treat this condition while reducing your need for regular injections in the future.
Cardiovascular disease is the second largest cause of death in the UK, with Alzheimer's and Dementia in first place. A study published by Wockhardt Hospitalsshows the link between B12 and coronary heart disease, but vitamin supplementation can reduce these risks.
Homocysteine is an amino acid that can increase the chances of heart attacks and strokes by narrowing the arteries. However, some specialists believe that a range of B vitamins, including B12, offer homocysteine-lowering interventions, but there's not enough research to prove this definitively.
Supports mental and physical well-being
Some studies - such as the one published by the National Library Of Medicine, suggest that B12 plays a role in reducing the symptoms of melancholic depression. However, research is limited to non-melancholic depression.
Some individuals, particularly older adults, may have difficulty absorbing B12 from food due to digestive issues or a lack of intrinsic factor, a protein necessary for B12 absorption.
If you notice you frequently have an upset stomach, feel weak and have chest pains or a rapid heartbeat, it could be a sign that your body can't absorb B12 from food. In these cases, supplements could be especially beneficial.
Pregnancy and breastfeeding
Taking vitamin supplements during pregnancy and when breastfeeding can ensure healthy foetal development and stimulate breast milk production. Pregnant women should consume a healthy and balanced diet of fortified foods, fish, meat and dairy products.
However, if you're vegan or are intolerant to certain foods, adding Vitamin B12 and folic acid supplements can give your body - and baby - additional support.
