Sisu Vitamin B12 Methylcobalamin - 5000 mcg - Together with vitamin B6 and folic acid, vitamin B12 is one of the powerhouse trio of B vitamins that help to decrease and normalize the homocysteine levels in our body. Increased homocysteine levels can cause the build-up of plaques in the artery walls (atherosclerosis), which can lead to heart disease or stroke. B12 deficiency is also associated with complications in pregnancies and neurological disorders. Vitamin B12 is also essential to help regulate the hormonal balance in pregnant and menopausal women and also in those using oral contraceptives. Vitamin B12 supplementation is recommended at any age, but it may be particularly beneficial for older people who suffer from age-related degenerative conditions and for people who have a vegetarian or a vegan diet as it is found in meat and seafood.
