The 15 g Bedtime Collagen Trick That Cut Night Wake-Ups by 27%
Waking up repeatedly through the night can quietly sabotage your recovery, even when training and nutrition are dialed in. A small trial found that 15 g of collagen peptides taken an hour before bed cut polysomnography-recorded awakenings from 29.3 to 21.3, roughly 27% fewer. Participants also scored better on a morning Stroop test. But total sleep time, sleep latency and sleep efficiency didn't budge, and the study involved just 13 men over 7 nights with an industry-supplied product. Here's what the data really shows and how lifters might test it safely.
SLAB51 Probiotic: One Week Added 33 Seconds for Elite Athletes
One week of the multi-strain probiotic SLAB51 helped elite athletes last about 33 seconds longer on a treadmill test, but a single dose did nothing and VO2max didn't change. The randomized, double-blind crossover trial also found higher levels of the antioxidant enzyme SOD before exercise. So what is SLAB51, and why might gut bacteria influence endurance at all? This article breaks down the study design, the numbers, and what athletes can realistically take from them. It also covers the limits: a small sample of elite men and a very short intervention.
