Many of us reach for vitamins or supplements thinking they’ll boost our health, sharpen our minds or protect our brains. But what if some of those “safe” supplements are silently harming your nervous system? A neurologist recently warned that three popular supplements can pose significant risks when taken in excess — or without proper guidance. Let’s unpack what to watch out for, why it matters, and how to protect yourself.
Why You Should Pay Attention
Despite the common belief that more vitamins equals better health, the truth is more complex. Supplements can be helpful, but they’re also unregulated in many cases and may carry hidden dangers. For example:
-
A large industry has grown around “brain health” or “cognitive enhancement” supplements — but many have little scientific backing and may contain undisclosed ingredients. Being Patient+1
-
Experts report rising cases of nerve damage (such as peripheral neuropathy) linked to otherwise over‑the‑counter vitamins. ABC+1
-
The neurologist featured in the headline specifically flagged three supplements: excessive zinc, vitamin A, and vitamin D. The Times of India+1
Because the brain and nervous system are so critical — and delicate — it’s wise to approach supplementation with caution rather than blind optimism.
