Too much homocysteine, an amino acid the body normally clears with vitamins B12, B6 and folate. A raised level can reflect low B vitamins or reduced kidney function and is linked to heart risk, but lowering it has not been shown to prevent heart attacks.
Our comprehensive check-up screens for raised homocysteine and hundreds of other conditions.
Vitamin B12 is a water-soluble vitamin essential for the production of red blood cells, the synthesis of DNA, and the healthy functioning of the nervous system. It also supports brain function and energy metabolism. The body cannot make B12 on its own and relies on dietary sources such as meat, fish, eggs, and dairy. Excess B12 is stored in the liver, so deficiency can take time to develop but may lead to serious health issues if not addressed.
Folic acid (Vitamin B9)Folic acid, or folate in its natural form, is a water-soluble B vitamin that plays a key role in cell division, DNA synthesis, and red blood cell formation. It is especially important during periods of rapid growth, such as pregnancy and adolescence. Folate is found in leafy greens, legumes, citrus fruits, and fortified foods. The body cannot produce folate and depends on regular dietary intake.
