Creatine + Beta-Alanine: The Stack Bonus Researchers Couldn't Find
The creatine plus beta-alanine stack is marketed as a performance power couple, but a new network meta-analysis of 52 randomized trials found no synergy between them. Creatine alone significantly improved sprint, jump, repeated-sprint and upper-body endurance outcomes versus placebo. Beta-alanine's effects were non-significant or context-specific, and the combo added nothing beyond creatine. Here's what the study did, where it falls short, and what it means for your supplement budget.
Baking Soda + Sprints: The Dose That Beat Placebo on Every Test
A new randomized trial in basketball players found that adding sodium bicarbonate (baking soda) to four weeks of sprint interval training beat placebo on jumping, sprinting, agility, Yo-Yo distance and Wingate power. The higher dose of 0.45 g/kg then outperformed 0.3 g/kg on every single measure. That makes it a cheap, tempting add-on for team-sport athletes. But the stomach is the catch, and the study is small, short and male-only. Here's the dose math, the GI-distress workarounds, and who this actually applies to.
