PRP Injections: Do They Actually Work?
Platelet-rich plasma (PRP — a concentrate of your own blood platelets, spun down and injected back into an aching joint, tendon, or scalp) is one of the most heavily marketed treatments in modern medicine.
Peptides, NSAID alternatives, soft-tissue and joint trials.
Most herbal joint remedies collapse the moment you pool the trials. Devil’s claw is one of the rare exceptions.
Platelet-rich plasma (PRP — a concentrate of your own blood platelets, spun down and injected back into an aching joint, tendon, or scalp) is one of the most heavily marketed treatments in modern medicine.
White willow bark is the plant that gave the world aspirin — its active constituent, salicin, is metabolized in the body to salicylic acid, the same molecule at the core of the pill in your cabinet. That heritage is the whole story, in two directions.
Glucosamine and chondroitin are the best-selling joint supplements on earth, and the pitch is intuitive: feed your cartilage its own raw materials and it should rebuild. The trouble starts when you follow that logic into the body.
MSM — methylsulfonylmethane, the organic-sulfur compound that turns up in nearly every joint and recovery formula on the shelf — is one of those supplements where the honest answer sits squarely between the hype and the dismissal.
Cannabidiol is now in oils, gummies, roll-ons, and recovery balms, sold as the natural fix for arthritis, chronic pain, sore muscles, and post-workout inflammation. The marketing is everywhere.
Strap a cuff high on the arm or thigh, dial it to partly choke the blood flow, then lift weights so light they’d normally do nothing — 20 to 40 percent of your max — and the muscle grows anyway. It sounds like a gimmick. It isn’t.
Serrapeptase — serratiopeptidase, an enzyme originally pulled from the gut of silkworms — is one of the supplement aisle's great over-promisers.
Lie back in a dark, silent tank of skin-temperature water so dense with Epsom salt that you float without effort, and the outside world goes quiet — no light, no sound, no gravity to fight, barely any sensation of your own body.
Frankincense is one of the oldest substances humans have burned, traded and rubbed on aching joints — and, unusually for a supplement-aisle botanical, the modern joint claim is actually backed by randomized trials.
Tart cherry — the Montmorency variety, sold as juice, concentrate, or powder — is one of the few “functional food” supplements with real human trial data behind it. But the three claims it carries are not equally well supported.
Supply line plus workforce mobility — that’s the mechanism case for the most common recovery peptide pairing. It’s a real case. It’s also not what most articles claim it is.
For the better part of a decade, the recovery-peptide duo lived almost entirely in animal labs and clinic-grey markets. In early 2026, two properly registered Phase 2 trials changed that.
Cold water immersion (CWI) is a genuine hormetic stressor — the cellular mechanisms are real. But the protocols matter enormously, the sex and age differences are real, and "do a cold plunge after every workout" is actively wrong for anyone focused on build…
The STAMINA trial (NCT05422885) ran dasatinib + quercetin in twelve older adults with early memory decline over twelve weeks. No serious adverse events. Memory improved in the subgroup with the lowest baseline scores.
Lixisenatide, a GLP-1 receptor agonist used for diabetes, reduced motor disability progression in early Parkinson's disease in a 2024 NEJM phase II trial. The exenatide data goes back a decade.
Turmeric is the rare supplement-aisle compound where the joint-pain claim is genuinely backed by randomized trials — and not just against placebo.
The Laukkanen group followed 2,315 middle-aged Finnish men for more than two decades and reported that men using a sauna 4–7 times a week had roughly half the cardiovascular mortality of men using it once a week. That headline has be…
HMB — the leucine metabolite that drove the late-1990s wave of muscle-preservation research — has spent the last decade being tested in the population it was always best matched to: older adults with sarcopenia.
Eli Lilly's TRIUMPH-4 trial reported up to 71.2 lb average weight loss and a 75.8% reduction in WOMAC pain in adults with obesity and knee osteoarthritis. The headline is real.
