The Student Athlete’s Evidence-Based Stack
In one paragraphThe Student Athlete’s Evidence-Based Stack — the honest news for anyone 18–24: the supplements with the strongest human evidence for training are also the cheapest ones. No numeric effect size is reported in Magellan's The Student Athlete’s Stack guide. The guide grades 5 products against the cited research.

The honest news for anyone 18–24: the supplements with the strongest human evidence for training are also the cheapest ones. Creatine monohydrate is the most-studied sports supplement in existence; omega-3s, vitamin D and magnesium cover the gaps student diets actually have. Skip the proprietary blends — the four cards below are the stack. Each links its studies.
How the picks grade out
Of the 5 picks here, 1 is graded “Strong evidence”, 3 “Moderate evidence” and 1 “Measurement tool”. Every grade below links to the product’s full evidence page and its PubMed citations.
The whole stack, four products
Roughly a dollar a day combined at typical serving sizes — read each monograph for dosing evidence and caveats.
Across meta-analyses and randomized trials, creatine monohydrate combined with resistance training modestly increases lean/muscle mass (about +1.4 kg in older-adult trials) and upper- and lower-body strength, including in older adults. Memory performance…
Dose used in studies: 3–5 g/day (creatine monohydrate); an optional ~20 g/day loading week works faster but isn’t required
What the evidence actually says: One of the most studied supplements there is: dozens of randomized trials and meta-analyses show reliable gains in strength, power and lean muscle alongside resistance training, and it is well tolerated in healthy people. The strong evidence is for muscle and exercise performance; cognitive, bone and healthy-aging benefits are promising but less settled. It supports training — it is not a treatment.
“creatine monohydrate has favorable effects on indices of aging muscle and bone”

Across large randomized trials and meta-analyses, marine omega-3s reliably reduce serum triglycerides (roughly 15% at higher doses) and modestly lower blood pressure and resting heart rate, but their effect on cardiovascular events is mixed and depends on…
Dose used in studies: Typical studied range 0.5-4 g/day EPA+DHA; triglyceride and blood-pressure effects are dose-dependent, clearest around 2-3 g/day. Event-reduction evidence is for prescription 4 g/day purified EPA in high-risk patients.
What the evidence actually says: Standard over-the-counter doses did not prevent cardiovascular events or cancer in large trials (VITAL, STRENGTH) and meta-analyses, though triglyceride lowering is real. Doses above 1 g/day carry a genuine atrial-fibrillation signal - about 13% higher incident risk in a large cohort of healthy users.

Large randomized trials and meta-analyses give a mixed picture. In generally healthy, vitamin-D-replete adults the two biggest trials were null on their primary endpoints: VITAL (25,871 people, 2,000 IU/day for a median 5.3 years) did not reduce invasive…
Dose used in studies: The RDA is 600 IU/day (ages 1–70) and 800 IU/day (over 70); the large VITAL trial used 2,000 IU/day, and the tolerable upper limit for adults is 4,000 IU/day.
What the evidence actually says: Strong for correcting deficiency and bone health. In vitamin-D-replete adults the biggest RCTs (VITAL, DO-HEALTH) were null for cancer, cardiovascular events, fractures and mortality. Lower cancer mortality with daily dosing, fewer autoimmune diseases and preserved telomeres are secondary signals that need replication — benefit is clearest in people with low baseline levels.
“Vitamin D supplementation was associated with a reduction in cancer mortality but not all-cause or cardiovascular mortality in this meta-analysis of randomised controlled trials.”

Pooled analyses of randomized trials indicate oral magnesium lowers blood pressure by a small amount—about 2 mmHg in a 34-trial analysis—with larger reductions in people who are hypertensive, magnesium-deficient, or insulin-resistant, and generally no…
Dose used in studies: 250–500 mg elemental magnesium/day (sleep trials used 250 mg as bisglycinate or 500 mg; BP analyses center near ~370 mg/day)
What the evidence actually says: Effect sizes are small — about 2 mmHg for blood pressure and a modest improvement in insomnia scores — and benefits look greatest in people with low baseline magnesium intake. Most evidence comes from other salt forms (oxide, citrate), so glycinate-specific superiority claims outrun the data.

Prove it’s working
Strength numbers beat scale numbers. A grip dynamometer is the cheapest objective progress meter you can own.
Across large prospective cohorts and meta-analyses, lower grip strength is consistently associated with higher all-cause and cardiovascular mortality, incident cardiovascular disease, disability, and, in some studies, cognitive decline and depression, often…
Dose used in studies: Three squeezes per hand, seated, elbow at 90 degrees, best value recorded - and the same chair, same arm position, same time of day every time. Monthly is plenty. What matters is your own trend over years, not where you sit against a population chart.
What the evidence actually says: Grip strength is one of the most durable prognostic markers in epidemiology: in PURE across 17 countries and in half a million UK Biobank participants, lower grip tracked all-cause and cardiovascular mortality, and it did so after adjustment and across very different populations. This specific device also clears the bar that most consumer instruments fail - the Camry digital dynamometer has been tested head-to-head against the Jamar, the reference instrument, with excellent reliability and correlations of 0.97-0.99, so a cheap unit is genuinely measuring the thing. Two honest caveats - grip strength is a marker of overall muscle and health rather than a target in itself, and squeezing a dynamometer more often will not move it, since the intervention that moves it is resistance training, which is graded separately and is where the actual benefit lives. The second is that this is the site's second grip dynamometer: it measures exactly what the other one measures, the other is graded strong, and nothing in the evidence says a 200 kg-capacity unit tells a middle-aged adult anything a 90 kg one does not - buy one, and let price decide which.

Why this guide exists
Most “best of” lists are ads wearing a lab coat. Ours are built backwards — the site’s PubMed-cited monographs and evidence grades came first, and these pages only organize what already survived that process. A product cannot buy its way in, and a grade never moves because a commission does.
