Synthetic vs Natural Vitamins

Does the source actually matter?

THE WINNERIt Depends

Natural vitamin E (d-alpha) beats synthetic (dl-alpha). Methylfolate beats folic acid for some people. For everything else, synthetic is chemically identical and much cheaper. Don't pay 5x more for "natural" vitamin C.

Myth vs Reality

Myth: "Your body knows the difference between natural and synthetic." Reality: A molecule is a molecule. Ascorbic acid from an orange is identical to ascorbic acid from a lab. Your cells can't distinguish the source.

Why It Depends Sometimes

For vitamin E: natural wins definitively (2x better retention). For folate: methylfolate is better for those with MTHFR mutations. For vitamin C, B vitamins, D3, minerals? No meaningful difference. Your body doesn't care.

Common Questions

d-alpha-tocopherol = natural. dl-alpha-tocopherol = synthetic. That "l" makes a big difference. Check the label.

The Bottom Line

Pay more for natural vitamin E and methylfolate. For everything else, synthetic is fine. The "natural is better" marketing costs you money without improving your health.
