The supplement shelf

Every supplement worth knowing about, on one shelf — what it does, how strong the evidence is, and the safety fine print.

Famous stacks, decoded

Podcast hosts discuss ingredients for specific goals, describe their own use, and promote sponsored products \u2014 three different things. Sponsored products are ads, not scientific endorsements, and \u201Cdiscussed on a show\u201D is not \u201Cproven to work.\u201D Everything on this shelf gets the same treatment: what it does, how strong the evidence is, and the safety fine print. Don\u2019t copy anyone\u2019s whole stack, especially if you take medication or have a health condition.

Buy smart

Supplements aren\u2019t FDA-approved the way drugs are, so labels can overpromise. Look for third-party testing seals (NSF or USP) on the label \u2014 they verify dosage and purity. And read the full ingredient list: additives and sweeteners vary wildly, and some (like erythritol) have been linked to cardiovascular concerns in research.

Fuel first

Supplements sit on top of food

The least exciting and most effective performance enhancer is dinner. Here's the short version of what your stack stands on.

1

Protein from the plate

Meat, fish, eggs, dairy, legumes, tofu — active people generally do well around 1.4–2.0 g per kilo of body weight per day. Hit that with food first; powder just fills gaps.

2

Creatine from the kitchen

Meat and fish contain creatine, but diet alone rarely maxes muscle stores — that's exactly why it's the most-studied supplement there is. Vegetarians tend to see the biggest response.

3

Water and sleep

Dehydration and short sleep tank performance more than any supplement can fix. Eight hours and a water bottle beat a shopping cart.

The order of operations

Food → sleep → training consistency → then supplements. If the first three aren't handled, the fourth is decoration.
