Caffeine before workout dosage is simpler than most pre-workout marketing makes it sound. The best-supported protocol is 3 to 6 mg per kg of body weight taken about 30 to 60 minutes before training, based on the 2018 IOC consensus and the 2021 ISSN position stand. Lower doses under 3 mg/kg can still help some …

Protein bars healthy enough to earn a place in your diet? Sometimes. A decent bar can be a practical protein source, but plenty are just processed snacks with a protein halo. The smart move is to read five lines first: protein, total carbohydrate, dietary fiber, total sugars, and added sugars, then check whether sugar alcohols …

Not eating enough to build muscle usually looks less dramatic than people expect. It often shows up as stalled strength, flat bodyweight, nagging fatigue, poor sleep, slow recovery, more colds, or menstrual changes rather than obvious starvation. In sports medicine, that pattern sits under low energy availability and, at the more serious end, RED-S. If …

Protein GLP-1 weight loss usually means aiming higher than the standard RDA. Current 2025-2026 reviews and guidance commonly land around 1.2-1.6 g/kg/day during active weight loss, paired with resistance training, because lean mass can make up roughly 25-40% of the weight lost on GLP-1 and dual-incretin drugs. If your appetite is low, the real challenge …

The best electrolyte powder ingredients start with sodium. For most people, that’s the main thing that determines whether a product is useful for long, hot, sweaty training or just expensive flavored water. Potassium has a secondary role. Carbohydrate can matter for longer sessions. Magnesium is the most over-marketed ingredient here, because current reviews still don’t …

Magnesium muscle recovery claims are partly right and often oversold. If your intake is low, correcting it may help cramps, sleep, and how recovered you feel, but the research does not show a large, consistent effect on muscle soreness or performance recovery in everyone. For supplements, citrate and glycinate generally absorb better than oxide. A …

Fiber athletes eat can help gut health, recovery nutrition, and day-to-day health, but it is not a proven direct performance enhancer on its own. The practical play is simple: get enough fiber across the day, keep it lower in the 1 to 2 hours before hard training, and increase intake gradually. That gives you the …

Creatine brain benefits are promising, but they’re not settled science. Human studies from 2003 to 2026 suggest creatine can raise brain creatine or phosphocreatine levels and may help short-term memory, mental fatigue, and performance under sleep deprivation. The catch is sample size. Most trials are small, protocols differ, and cognitive results are mixed, with older …

You set an early alarm, lace up your shoes, and then hit the usual problem: you want to train, but food sounds terrible. That gap matters more than most people admit. After an overnight fast, blood glucose is lower, liver glycogen is reduced, and some workouts feel much harder than they should. The mistake is …

Electrolyte powders now sit next to protein tubs and pre-workouts, which makes them look essential for every gym session. Most everyday workouts do not create the kind of fluid and sodium losses that demand a specialty drink, yet some training conditions do. The useful question is not whether electrolytes are good or bad. It is …
