A recent Lithuanian Sports University study examined short‑term broccoli powder supplementation in 17 healthy men performing an incremental bike‑ergometer test. Participants consumed 10 g of broccoli powder (0.5 % mustard seed) for 14 days, which significantly increased urinary sulforaphane, confirming absorption. However, the supplement did not alter plasma malondialdehyde, blood lactate, exercise performance, or muscle‑power recovery. Researchers note the modest exercise intensity and short duration may have masked potential benefits, recommending trials in older or metabolically stressed groups.
A Nestlé‑backed randomized trial gave healthy men 714 mg nicotinamide and 19 mg pyridoxine daily for nine days after intense eccentric exercise. The B‑vitamin combo boosted muscle stem cell numbers by 29% and accelerated differentiation markers—MyoD+ cells rose 67%, myogenin+ cells 34%,...
A randomized, double‑blind trial in Japan found that a daily 100 ml drink containing 10 billion CFU of Lactiplantibacillus plantarum 299v reduced bowel‑movement frequency and days with defecation in healthy adults prone to loose stools. After eight weeks, the probiotic group averaged 6.7...
A recent JAMA cohort study of 131,000 adults found that drinking 2–3 cups of caffeinated coffee daily (≈300 mg caffeine) is associated with the lowest risk of dementia, while decaffeinated coffee showed no benefit. The finding aligns with a 2024 umbrella...
