Practical Tips

Milk thistle, artichoke, and NAC for the liver: what clinical studies have really shown, where the evidence ends, and when a doctor is needed instead of a supplement.

What studies have really shown about supplements for sarcopenia in older adults: creatine, vitamin D, omega-3, and HMB compiled with numbers from meta-analyses.

What GLA does to healthy skin, what it does not do in eczema, what doses were used in studies, and what the EMA monograph for evening primrose oil really allows.

Glutathione in capsules, liposomal or NAC? What has really been measured in humans: Witschi 1992, Richie 2015, Sinha 2018, Sekhar 2011. No empty promises.

Spermidine extends life in mice and induces autophagy in cell culture. In humans, the largest randomized trial did not show memory improvement after 12 months.

Caffeine before training: what the ISSN position really says about the dose of 2 mg/kg, what the meta-analyses of strength measured, and what thresholds EFSA provided in its 2015 opinion.

Detox, green coffee, CLA, echinacea, glucosamine, and multivitamins under scrutiny. We check in original studies which supplements are really not worth the money.

Measured detection windows for CBD in blood and urine, cutoff thresholds used in drug tests, and what the Spindle study did not check at all.

Caffeine, EGCG, capsaicin, L-carnitine, and ephedrine compared with meta-analyses. We show what the numbers from studies say and where marketing diverges from the data.

Indica, sativa or hybrid? Genomics does not confirm the division. What really determines the effect: the ratio of THC to CBD and the terpene profile. Plus a table of differences.
