Why Should you take Vitamin B12 Tablets?

If you don’t have a balanced diet or you avoid eating animal products that contain natural B12, taking Vitamin B12 supplements will boost your overall wellness.

There are also special circumstances when your body may need extra amounts of Vitamin B12. Our supplements are ideal for pregnant or breastfeeding women as Vitamin B12 and folate support fetal development. They are also crucial for older adults who cannot consume enough Vitamin B12 due to a loss of appetite.

100% Pure Vegan B12 Supplement

Vitamin B12 is usually found in meat and other dairy products; it is not viable for vegans or vegetarians. Some animal products such as fish, meat, and dairy contain this vitamin, and it can also be manufactured synthetically. Our vegan B12 tablets are 100% vegan and vegetarian-friendly. So, if you’re a vegetarian or a vegan, you can still get enough nutrients. Our one-a-day tablets provide you your daily dose of vitamin B12, so your body gets the nutrients it needs to tackle the day with confidence.

Vitamin B12 is essential for your body to function at its best. B12 boosts energy, is great for the brain and even helps bolster your inner defences.
