MyBody-X angle on MTHFR Senioren

Your MyBody-X test may indicate a variant in the MTHFR gene (e.g., C677T or A1298C). These variants can reduce the efficiency of converting folate into its active form, methylfolate. For seniors, this is relevant because aging itself can impair nutrient absorption and metabolism. Supplementing with methylfolate (5-MTHF) instead of synthetic folic acid is a common recommendation, especially if homocysteine levels are elevated. However, the evidence is mixed: while methylfolate effectively lowers homocysteine, robust proof that it reduces cardiovascular events or cognitive decline in seniors is lacking. Moreover, high-dose methylfolate can mask a vitamin B12 deficiency, which is more common in older adults and can lead to irreversible neurological damage. Therefore, any supplementation should be discussed with a healthcare provider who can assess B12 status, homocysteine, and overall health. The genetic test provides a clue, not a diagnosis. Clinical utility remains debated, and lifestyle factors (diet, B12 intake) are equally important.
