Key takeaways NMN reliably raises blood NAD+ in every published human trial, at doses from 100 mg to 1,250 mg/day — that part is well replicated (Yoshino et al. 2021, Science, Yi et al. 2022, GeroScience). What NAD+ elevation actually does for a healthy adult’s function is still thin: a 2024 systematic review of 10 … Read more
Key takeaways Strongest evidence: creatine monohydrate at 3-5 g/day increases upper-body strength by roughly 4.4 kg and lower-body strength by roughly 11.4 kg beyond resistance training alone in adults under 50, and produces similar gains in older adults doing resistance training (Burke et al. 2024, Sharifian et al. 2025). Cognitive benefits are real but narrow … Read more
Key takeaways The best-supported “supplement” intervention in asthma isn’t a capsule at all — it’s medically administered IV magnesium sulfate for selected severe acute attacks, per Cochrane (odds ratio 0.10 for admission in the severe subgroup). Vitamin D is reasonable to correct a documented deficiency, but an updated Cochrane review found no evidence it reduces … Read more
Key takeaways WHO estimates asthma affected 363 million people in 2023 and caused 442,000 deaths, with most deaths linked to under-diagnosis and under-treatment rather than disease severity alone (WHO asthma fact sheet). GINA states SABA-only (reliever-only) treatment raises exacerbation risk, worsens lung function, and increases asthma-death risk — low-dose ICS or as-needed ICS-formoterol cuts severe … Read more
