Start from the deficit, not the trend

The best supplement is the one your body is actually missing. Blood work, diet review, and lifestyle context should drive the decision — not the label on the front of the bottle or a viral video.

Evidence, dose, and form

Once you know what to target, look at three things: is there real human evidence, is the dose in the studies close to what the product provides, and is the form bioavailable. A cheap product at the wrong dose is more expensive than a good one at the right dose.

Fit it into your life

A supplement stack you cannot maintain is worthless. Pick the smallest number of products that cover the biggest gaps, tie them to an existing habit like breakfast or brushing your teeth, and reassess every few months.
