Vitamin B7: Why a Hair Supplement Belongs on Your Medical List

Vitamin B7: Why a Hair Supplement Belongs on Your Medical List

A supplement bought for stronger nails or thicker hair can matter during a medical appointment for something entirely different. Biotin, also called vitamin B7, can interfere with certain laboratory tests. The result may look reassuring when it should not, or suggest a problem that is not actually present.Read More »Vitamin B7: Why a Hair Supplement Belongs on Your Medical List

Vitamin B5: The Nutrient in Your Food Is Not the Same Question as the Claim on a Cream

Vitamin B5: The Nutrient in Your Food Is Not the Same Question as the Claim on a Cream

A moisturiser, an acne supplement and a product advertised for cholesterol may all mention vitamin B5. That shared name can make their benefits sound interchangeable. They are not.

Vitamin B12: Deficiency, Blood Tests, Food and Treatment

Vitamin B12: Why a Normal Blood Count or a Good Diet May Not Tell the Whole Story

Persistent tingling in the feet deserves attention even when a routine blood count looks normal. Eating meat does not rule out vitamin B12 deficiency, and feeling tired does not prove it. These apparent contradictions make more sense once you separate three questions: how much B12 reaches your diet, how much your body absorbs and whether it is working normally inside your cells.Read More »Vitamin B12: Why a Normal Blood Count or a Good Diet May Not Tell the Whole Story

Ginkgo Biloba: Why a Memory Claim Is Not the Same as a Proven Benefit

Ginkgo Biloba: Why a Memory Claim Is Not the Same as a Proven Benefit

A bottle of ginkgo biloba can seem to offer an answer to several different worries: losing concentration at work, forgetting appointments, developing dementia or living with ringing in the ears. The problem is that these are not interchangeable conditions. Evidence about one cannot simply be borrowed to support another.Read More »Ginkgo Biloba: Why a Memory Claim Is Not the Same as a Proven Benefit
