Supplements That Actually Work: A Short, Honest List

The supplement industry is built on hope and thin evidence. Walk into most “biohacking” spaces and you’ll be sold thirty jars. Walk into ours and the list is deliberately short — because most supplements, for most people, do nothing but produce expensive urine. Here’s what the evidence actually supports.

The short shortlist

Vitamin D3 (+ K2). Deficiency is genuinely widespread — even in sunny climates, because we live indoors. Low vitamin D affects immunity, mood, bone health and more. This is one of the few worth taking almost by default if your blood level is low — which is why we measure it first.

Omega-3 (EPA/DHA). Solid evidence for cardiovascular and anti-inflammatory benefit if you don’t eat much oily fish. Quality and dose matter; a token amount in a multivitamin doesn’t count.

Magnesium. Involved in hundreds of enzymatic reactions; many people run low. Often helps sleep and muscle function. Cheap, safe, reasonable.

Creatine monohydrate. The most-studied performance supplement, and increasingly interesting for cognition and healthy ageing — not just gym gains. Well-evidenced and inexpensive.

Protein powder — if you struggle to hit protein targets from food. A convenience tool, not a magic powder, and it supports the muscle mass that actually drives longevity.

That’s most of it. Notice what’s not here: a wall of exotic compounds.

The “maybe, with a doctor” tier

Some compounds have promising but immature evidence: certain longevity molecules, and hormone optimization where labs justify it. These belong in a conversation with a physician who’s seen your panel — not on an impulse buy. On the retreat, anything in this tier is discussed in the Day-9 lecture and one-to-one with the doctor, tied to your actual markers.

The frontier: NAD+, exosomes, peptides

These are genuinely interesting and genuinely early. We offer optional NAD+ and exosome protocols through a licensed partner clinic — framed honestly as frontier therapies with emerging evidence, priced separately, never as the core of the program. Anyone selling these as proven miracles is ahead of the science.

The rule that beats any list

Test, don’t guess. The reason we don’t hand everyone the same stack is that the right supplement is the one filling your measured gap. Blanket protocols waste money and occasionally do harm (fat-soluble vitamins and iron can overshoot). Your blood work should write your supplement list — then a re-test should check it’s working.

That’s the whole philosophy of the longevity module: evidence-based, measured, and refreshingly short. If a program’s supplement list is longer than its diagnostic list, that tells you what it’s really selling.
