Health Condition Supplement Protocols — Evidence-Based
What are condition protocols? Each protocol is a complete, evidence-ranked supplement plan for a specific health condition. We review the clinical trial literature (RCTs and meta-analyses), rank every supplement by strength of evidence, and provide specific product recommendations with clinical doses, timing, drug interaction warnings, and cost per day.
The overlap nobody mentions: five supplements cover most of these
Each protocol below is built for one condition, which is the right way to write them and the wrong way to shop from them. Read across all six and the same bottles keep reappearing — so someone with two of these concerns is being pointed at the same purchase twice, from two different pages, with no indication that it is the same purchase.
We resolved every product each protocol links to back to its supplement category. Of the 19 distinct supplements across the 6 protocols, 5 appear in more than one:
| Supplement | Protocols | Which ones |
|---|---|---|
| Omega-3 | 4 of 6 | Anxiety & depression, Joint pain, PCOS, Stress |
| Ashwagandha | 3 of 6 | Anxiety & depression, Sleep, Stress |
| Magnesium glycinate | 3 of 6 | Anxiety & depression, Sleep, Stress |
| Vitamin D3 | 3 of 6 | Anxiety & depression, Immune support, PCOS |
| L-theanine | 2 of 6 | Sleep, Stress |
What that means if more than one applies to you. Sleep, stress and anxiety overlap almost completely — ashwagandha, magnesium glycinate and L-theanine run through all three — so treating them as three separate shopping lists means buying the same three things and paying for them repeatedly. Omega-3 is the single broadest item here, appearing in four of the six. Build one stack from the union, not three stacks from three pages.
The other 14 supplements are genuinely condition-specific: myo-inositol and berberine belong to PCOS, glucosamine and chondroitin to joint pain, and they do not transfer. That split — a handful of broadly useful things plus a short list of specific ones — is the honest shape of supplementation, and it is easier to see across six protocols than inside any one of them.
The same supplement is not equally well supported in every protocol
A supplement appearing in four protocols is not four times the evidence. It usually means one well-established role plus several plausible extensions, and the extensions are not all equally settled. Worth knowing which is which before you decide what to keep taking.
Omega-3 is the clearest case. Its strongest evidence is for lowering triglycerides, where the effect is large and consistent, and that is not in dispute. Its effect on inflammatory joint pain is much more modest: a systematic review of 23 randomised placebo-controlled trials in rheumatoid arthritis found a small reduction in pain that did not reach significance (SMD −0.16, 95% CI −0.40 to 0.09) (PMID 35900212). Same supplement, same dose, two very different strengths of claim — so “omega-3 works” is true and unhelpfully vague.
Magnesium is a genuine deficiency to correct, and a less settled sleep aid. Low magnesium intake is common, the requirement is well established, and correcting a real shortfall is worth doing on its own terms. Its use specifically as a sleep intervention is younger: a systematic review of trials using magnesium as a stand-alone treatment for sleep gathered twelve randomised trials and concluded that adequately powered studies are still needed before routine recommendation (PMID 42661485). That is an argument for realistic expectations about sleep, not against magnesium.
Ashwagandha is where the numbers themselves deserve a second look. A pooled analysis of 22 trials reports standardised mean differences of −5.88 for stress and −6.87 for anxiety (PMID 41644067). For scale, 0.8 is conventionally a large effect. Values near six would mean improvements of about six standard deviations, which no plausible intervention produces — results that size almost always reflect heterogeneity between trials or inconsistent outcome scales, and the authors call for better-designed studies for exactly that reason. Ashwagandha may well help with stress; the published effect size is not the reason to believe it.
What to take from that. Use the overlap to avoid buying the same thing twice, and use the individual protocol to set your expectations for your reason for taking it. Breadth of recommendation and strength of evidence are different axes, and the shared column above measures the first one.
Method: derived from the protocol pages themselves rather than from a
hand-kept list — every product each page links to, resolved to its catalogue
category, so this reflects what the protocols actually recommend and moves when they
change. Regenerated by data/pipeline/condition_overlap.py.
What it cannot tell you: whether taking one supplement for two reasons
means one dose or two — that depends on the doses each protocol specifies, so
check both pages before assuming a single bottle covers you.
Condition Protocols
Supplements for Anxiety and Depression (2026)
Evidence-ranked supplement protocol for anxiety and depression. Magnesium, omega-3, ashwagandha, vitamin D, and SAMe ranked by clinical evidence level. Medication interactions, dosing, and cost per day.
Supplements for Joint Pain & Arthritis (2026)
Evidence-ranked supplement protocol for joint pain and arthritis. Curcumin, glucosamine, chondroitin, omega-3, and collagen ranked by meta-analysis evidence. Medication interactions, dosing, cost per day.
PCOS Supplements (2026): Evidence-Ranked Protocol
Evidence-ranked supplement protocol for PCOS based on 46 RCTs. Myo-inositol, vitamin D, NAC, berberine, and omega-3 with clinical doses, timing, and drug interaction warnings.
Best Supplements for Stress (2026)
The three with real trial evidence: ashwagandha (lowered cortisol ~28% in an RCT), magnesium glycinate, and L-theanine. Doses, timing, what to skip, interactions, and cost per day.
Best Supplements for Fatigue & Low Energy (2026)
The honest, test-first protocol: supplements fix fatigue only when they correct a deficiency. Iron (low ferritin), B12, vitamin D, magnesium — plus why most "energy" pills do nothing.
Best Supplements for Immune Support (2026)
Vitamin D to prevent, zinc lozenges to shorten a cold. What the evidence actually supports for vitamin C and probiotics, the doses, and what to skip.
Best Supplements for Sleep (2026)
Evidence-ranked and honest: melatonin for falling asleep and jet lag, magnesium and ashwagandha for quality, glycine and L-theanine for winding down. Doses, timing, and what not to stack.
Best Supplements for Brain Fog (2026)
Brain fog is a symptom, not a diagnosis. Omega-3, B12, iron, and vitamin D — what actually helps (mostly by correcting a deficiency), what's only marketing, and when to see a doctor.
