The Vitamin You Take Every Morning Could Be Working Against Your Brain You take your multivitamin every day thinking you're doing the right thing. But if you're one of the 40-60% of people carrying the MTHFR gene variation, the folic acid in that bottle might be accumulating in your bloodstream instead of nourishing your brain — and it could even be masking a dangerous B12 deficiency your doctor's bloodwork can't catch. In this video, Dr. James Carter breaks down: Why synthetic folic acid isn't the same as natural folate The MTHFR gene mutation and why it affects nearly half the population How unmetabolized folic acid can block your body from using real folate The hidden link between high folic acid + low B12 and accelerated cognitive decline Why folic acid can mask a B12 deficiency on standard lab tests What to look for instead: L-methylfolate and methylcobalamin Homocysteine — the simple blood test almost nobody gets that predicts brain aging Practical steps to check your supplements and talk to your doctor If you've been feeling foggier, slower, or more forgetful than you used to and assumed it was "just aging," this video might change how you look at what's in your medicine cabinet. ⚠️ Disclaimer: Dr. James Carter is an educational persona.
