Best Vitamins & Supplements: Evidence-Based Guides

A registered dietitian compares magnesium bioavailability across glycinate, citrate, oxide, threonate, and malate with RCT evidence and cost-per-active-mg math.

You have probably seen Selank described in nootropic forums as the Russian government's answer to anxiety — an approved drug that sidesteps benzodiazepine dependence while also improving cognition. That narrative is compelling enough that it drives a meaningful grey-market trade in vials of unknown purity shipped from unregulated suppliers. The obvious follow-up question is whether

If you have severe osteoporosis, you have probably heard that most bone drugs work by slowing breakdown rather than building new bone. That framing is mostly accurate, and it is exactly why teriparatide gets attention: it works in the other direction. But is it for everyone with low bone density? Almost certainly not. And is

If you are searching for what adaptogens actually are, whether they work, and which ones have real clinical evidence behind them, the honest answer is: some do, for specific outcomes, in specific populations, at specific doses, and the marketing around almost all of them significantly overstates the evidence. This guide will break down the category

Synthetic oxytocin is the same nine-amino-acid molecule whether it arrives in an IV bag hanging above a labor-and-delivery bed or in a small amber bottle mailed from a compounding pharmacy. The FDA-approved version, sold under the brand name Pitocin, has been used in hospital obstetric wards since the 1960s, backed by decades of clinical data

You may have come across octreotide in a bodybuilding forum or a wellness thread with the vague framing that it "blocks GH" or helps with "spot reduction." That framing is worth pausing on, because octreotide is a serious prescription drug with a specific set of FDA-approved indications, a well-documented side-effect profile, and zero clinical evidence

Tesamorelin has one thing no other GHRH analog peptide can claim: an FDA approval. That approval is real, the Phase 3 trial data behind it are solid, and the mechanism is well understood. But the indication is narrow — HIV-associated lipodystrophy, specifically the excess visceral fat that accumulates in people on long-term antiretroviral therapy —

If you or someone you care for has been prescribed Lupron — or if you have seen leuprolide mentioned in the context of prostate cancer, endometriosis, or early puberty in a child — you have probably wondered how a single drug ends up treating three conditions that appear to have nothing in common. The honest

Every peptide article eventually circles back to the same molecule. When researchers argue that peptide drugs can be both precise and safe, they point to a century of clinical data. When skeptics ask whether synthetic chains of amino acids can actually replace a biological function, the answer is yes — and it has been yes

If you are choosing between Wegovy and Zepbound, the SURMOUNT-5 head-to-head trial gave a clear answer on average weight loss, but the average is not the only number that matters. Tirzepatide produced a mean body-weight reduction of 20.2 percent versus 13.7 percent for semaglutide at 72 weeks — a 6.5 percentage-point gap that is both
