Methylcobalamin is the active, ready-to-go form of vitamin B12. In contrast, cyanocobalamin is synthetic and requires conversion into methylcobalamin within the body before it becomes effective.

While some brands may opt for budget-friendly cyanocobalamin, we refuse to settle when it comes to selecting our ingredients, which is why we’ve included methylcobalamin in our OneVit Vitamin B12 formula.

Vitamin B12 helps keep the body’s production line of red blood cells in perfect working order.

When vitamin B12 reserves are depleted, it can prompt the production of unhealthy and deformed red blood cells that can’t transport oxygen efficiently. This can deal a serious blow to your energy levels and leave you feeling worn out.

Vitamin B12 also ramps up the body’s production of white blood cells - specifically CD8+ and NK immune cells, which hunt down and eliminate diseased cells to help fortify your body in the battle against pathogens.

On top of that, vitamin B12 helps shield your nerve fibres from damage and contributes to DNA stability. This helps maintain the rapid flow of messages between your brain and body while also ensuring your genetic blueprint remains intact.

If you’re running low on vitamin B12, you’re likely to feel unusually tired and short of breath. Your skin is likely to look paler than usual and your muscles might feel weak due to a potential dip in blood oxygen levels, which can be caused by a low red blood cell count.

You might also find that you can’t think as clearly as you usually do, causing you to feel irritable. In some cases, a vitamin B12 deficiency can also cause digestive symptoms such as nausea and a decreased appetite.

OneVit Vitamin B12 benefits the body and mind in a number of ways. Having cross-checked the claims against solid scientific evidence and the advice of our experts, we found that OneVit Vitamin B12:

• Contributes to energy levels by preventing conditions such as anaemia that affect the optimal transportation of oxygen in the body
• Supports immune responses by helping to boost the body’s levels of several types of white blood cells
• Helps protect nerve functions by shielding the protective covering around nerve fibres

You should start taking OneVit Vitamin B12 immediately, especially if you’re feeling fatigued or experiencing symptoms related to a B12 deficiency.

Yes - we recommend taking one serving per day, every day. Consistent use is essential to help prevent a deficiency, ensuring optimal energy levels, stronger immune responses and proper nerve functioning.

Vitamin B12 is water-soluble, making it easier to absorb on an empty stomach. For most people, this would mean taking OneVit Vitamin B12 in the morning (in a fasted state) - but depending on your schedule, you could take it at night too.

Some people will notice the desired results from taking OneVit Vitamin B12 from day one, while others might have to wait a few weeks. There isn’t an exact time frame because everyone’s built differently - but what we can say is that anyone with exceptionally low vitamin B12 levels is likely to benefit from taking OneVit Vitamin B12 quickly.

OneVit Iron tops our list of recommended supplements to take with OneVit Vitamin B12, given the collective boost this dynamic duo provides to your blood oxygen levels.

Iron aids the production of haemoglobin, which binds oxygen molecules with red blood cells, while vitamin B12 ensures the production of healthy red blood cells to begin with.

Taking them together can keep your blood enriched with oxygen so your muscles and organs get the energy they need at a cellular level for optimal functioning.

OneVit Vitamin B12 also pairs brilliantly with OneVit Magnesium for next-level nerve support. Vitamin B12 safeguards nerves from damage and magnesium calms the nervous system. When taken together, these supplements can keep you calm, focused and mentally agile.

Yes, OneVit Vitamin B12 is 100% vegan and vegetarian-friendly.

OneVit Vitamin B12 does not contain common allergens. However, if you have specific sensitivities, it’s always best to check the ingredient list to ensure it’s safe for you.

If you are pregnant or breastfeeding, it’s always recommended to consult with your GP or healthcare provider before taking OneVit Vitamin B12 to ensure it’s the right choice for you.

We would recommend speaking with your doctor if you want to take OneVit Vitamin B12 alongside any medication. While we aren’t aware of any contraindications between OneVit Vitamin B12 and a specific type of medicine, it’s always better to be on the safe side.
