The supplement aisle is overwhelming and full of hype. This is a broad, plain-language look at some of the most commonly used everyday supplements and what to look for when buying — not a prescription. Talk to your doctor or pharmacist before adding anything, especially if you take medications or have a health condition.

1. Vitamin D3

One of the most commonly recommended supplements, especially for people who get little sun. Look for third-party testing and a dose appropriate for you (your doctor can advise).

2. Omega-3 fish oil

A staple for those who don’t eat much fatty fish. Look for the EPA/DHA amounts on the label and a reputable brand with purity testing.

3. Magnesium

Popular for general wellness and sleep support. Different forms are absorbed differently, so read the label and ask a pharmacist if unsure.

4. Probiotic

Used to support gut health. Look for the strains and CFU count listed, and storage requirements — some need refrigeration.

5. Vitamin B12

Often used by those on plant-based diets or with low levels. Sublingual and tablet forms are both common; your doctor can confirm if you need it.

The bottom line

Supplements support a healthy diet — they don’t replace one. Choose third-party-tested brands, start with what your doctor recommends, and check current prices on Amazon.
