They also contain small quantities of melatonin and tryptophan, the likely basis for the sleep findings.","Tart cherry occupies an unusual place in sports nutrition: the evidence is decent, and the correct advice is still to use it sparingly. Both halves of that sentence matter.\n\nThe evidence first. Across a series of small controlled trials — marathoners, cyclists, resistance-trained lifters — montmorency cherry concentrate consistently reduced muscle soreness and sped the return of strength after genuinely damaging exercise. Inflammatory and oxidative markers moved in the same direction. The trials are small and a fair share were supported by the cherry industry, which argues for caution rather than dismissal, since the direction of effect has been reproduced by independent groups.\n\nThe sleep finding is a separate, smaller literature. Tart cherries contain melatonin and tryptophan in modest amounts, and trials have reported longer sleep time and better efficiency — improvements measured in tens of minutes, not transformation.\n\nNow the reason to be sparing. The post-exercise inflammatory and oxidative signal is not damage to be suppressed; it is the message that triggers adaptation. Blunt it every day and you risk blunting the training response along with the soreness — a pattern demonstrated most clearly with high-dose antioxidant vitamins, where chronic supplementation measurably reduced training adaptations. The same logic almost certainly applies here.\n\nSo the sensible protocol is tactical. Use it around competitions, tournaments, and congested fixture periods, where recovering fast matters more than adapting maximally: start four or five days out, continue for two or three days after. During a normal training block, when the entire point is to adapt to the stress, skip it and let the inflammation do its job.\n\nPractically, concentrate is far more economical than juice — 30 ml twice daily replaces half a litre of drinking. Watch the sugar load if you are using juice in volume, and note that whole tart cherries deliver the same anthocyanins with fibre attached.",[27,30,33,36],{"effect":28,"grade":15,"note":29},"Reduces muscle soreness after damaging exercise","repeated small RCTs, several industry-supported",{"effect":31,"grade":15,"note":32},"Speeds strength recovery after hard efforts","clearest after marathons and eccentric-heavy sessions",{"effect":34,"grade":15,"note":35},"Improves sleep duration and efficiency","gains measured in tens of minutes",{"effect":37,"grade":15,"note":38},"Lowers uric acid and gout flare frequency","observational and small trial evidence","Food, and safe as such.

Supplemental melatonin acts on MT1\u002FMT2 receptors to phase-shift that clock and modestly lower alertness — a timing signal, not a hypnotic, which is why dose timing matters more than dose size.","Melatonin is the most misunderstood popular supplement, and the misunderstanding is baked into how it is sold. It sits on the shelf next to sleep aids, gets dosed like a sleep aid, and disappoints people who expected a sleep aid — because it is not one. Melatonin is the hormone your brain uses to announce that night has arrived. Supplementing it does not sedate you; it moves the announcement.\n\nRead that way, the evidence sorts cleanly. Where the problem is timing — jet lag, shift work, the delayed sleep phase of night owls — melatonin has some of the best data in sleep medicine, with a Cochrane review finding it remarkably effective for jet lag when taken at the destination bedtime. Where the problem is garden-variety insomnia, meta-analysis finds it shaves an average of about seven minutes off sleep latency: real, but a fraction of what prescription hypnotics or CBT-I deliver.\n\nDosing is where practice diverges furthest from evidence. Receptor studies and dose-response trials point to 0.5-1 mg as sufficient — often more effective than the 5-10 mg gummies that dominate the market, which can leave morning grogginess and spillover of elevated melatonin into the next day. More timing signal is not more sleep. Equally important is the quality-control problem: analyses of retail products have found actual content ranging from a fraction of the label to several times it, so third-party-tested brands matter more here than almost anywhere.\n\nSafety at low doses and reasonable durations looks good, with grogginess and vivid dreams the common complaints, though long-term nightly use in healthy adults is less studied than the sales volume implies.

The catch is bioavailability: unformulated curcumin is poorly absorbed, rapidly metabolised, and quickly excreted, so plasma concentrations after an oral dose sit far below what the cell studies used.","Curcumin is the most-published natural compound in modern biomedical literature and simultaneously the standing example medicinal chemists use for a molecule that looks active in every assay and works in almost none of them.\n\nThe chemistry problem is specific and worth understanding. Curcumin is what is known as a PAINS compound — pan-assay interference — meaning it produces apparent hits in screening assays through non-specific mechanisms: it is unstable, chemically reactive, fluorescent, and prone to disrupting membranes. It also has terrible bioavailability, being poorly absorbed, rapidly conjugated by the liver, and swiftly excreted. A landmark review in the *Journal of Medicinal Chemistry* laid out the case that curcumin has never been shown to be a specific, useful drug candidate despite the thousands of positive papers.\n\nAnd yet the clinical picture is not empty. Curcumin has a genuine track record in one place: osteoarthritis pain. Multiple randomised trials, and meta-analyses pooling them, find meaningful reductions in knee pain and stiffness — several reporting effects comparable to ibuprofen or diclofenac, with fewer gastrointestinal side effects. The trials are mostly small, many use proprietary formulations from companies with an interest in the result, and the effect is modest. But the direction has been consistent enough across enough independent groups that dismissing it entirely is unfair.\n\nHow to hold both facts: the joint-pain finding is a clinical observation that stands on its own trial evidence, whatever the mechanism turns out to be. The sweeping claims — cancer prevention, Alzheimer's, depression, \"reduces inflammation\" as a general lifestyle proposition — rest almost entirely on the cell and rodent work that the pharmacology makes untrustworthy.\n\nIf you want to try it for joints, the formulation is not optional. Plain turmeric in food delivers almost nothing systemically. Use a bioavailability-enhanced product — piperine-combined, phytosome, or nanoparticle — at 500-1,500 mg of curcuminoids daily with food, and give it eight weeks. And take the interactions seriously: curcumin has genuine antiplatelet activity and inhibits several drug-metabolising enzymes, so it is not a free addition if you take anticoagulants.",[155,158,161,164],{"effect":156,"grade":78,"note":157},"Reduces osteoarthritis knee pain and stiffness","multiple RCTs; several comparable to NSAIDs, mostly small and often industry-linked",{"effect":159,"grade":15,"note":160},"Lowers circulating inflammatory markers","CRP and IL-6 reductions reported inconsistently",{"effect":162,"grade":15,"note":163},"Improves depressive symptoms as an adjunct","small trials, mostly alongside standard treatment",{"effect":165,"grade":166,"note":167},"Prevents or treats cancer","D","preclinical only; bioavailability and PAINS behaviour undermine the translation","Well tolerated in many trials, but concentrated or piperine-enhanced products have been implicated in drug-induced liver injury and may raise bleeding risk.

Relevant to the popular claims, it acts as a natural NMDA receptor antagonist and GABA agonist — a genuinely calming signature — and regulates vascular smooth muscle tone and neuromuscular excitability.","Magnesium is unusual on this list in that the deficiency is real and widespread. Dietary surveys consistently put a large share of adults below the estimated average requirement, and the reasons are structural: refined grains lose most of their magnesium in milling, soil concentrations have declined, and the foods richest in it — nuts, legumes, leafy greens, whole grains — are exactly what modern diets skimp on. Blood tests hide this well, since serum magnesium is defended tightly at the expense of bone and muscle stores.\n\nWhere it helps is where you would predict from a cofactor that participates in every ATP reaction. Sleep improves modestly, particularly in older adults and those with low intake — falling asleep faster, waking less. Subjective anxiety and stress ratings improve in a reasonably consistent set of trials. Blood pressure drops a few mmHg. Migraine prophylaxis has enough support that neurology guidelines mention it. And it genuinely helps constipation, though that is the citrate form doing what osmotic laxatives do.\n\nThe form question is where most of the money is wasted. Magnesium oxide is the cheapest and fills the majority of drugstore products; it is around 4% bioavailable and its main reliable effect is a trip to the bathroom. Glycinate (bisglycinate) is well absorbed, gentle on the gut, and the glycine itself has mild sleep-promoting properties — the sensible default for evening use. Citrate is well absorbed and mildly laxative, which is a feature or a bug depending on your situation. L-threonate is the form marketed for cognition on the basis that it raises brain magnesium in rats; it has its own entry here and a considerably weaker human case.\n\nCheck the label for elemental magnesium, not compound weight — \"500 mg magnesium glycinate\" may contain only 50-70 mg of actual magnesium, which is the number that matters.
