Your Top Health Questions Answered

Video summary

Andrew Huberman answers listener questions on late-night Alpha-GPC workouts, morning daylight, fertility, memory, menopause, surgery recovery, and finding passion.

In a listener Q&A, Andrew Huberman recommends Alpha-GPC, usually 600–900 mg, as a caffeine-free option for late strength training, while cautioning about frequent use and TMAO; he suggests pairing it with 600 mg of garlic and winding down with a hot shower, long-exhale breathing, and post-workout food. He explains that morning ambient daylight helps set circadian timing even when viewed facing west, and argues health routines should be flexible rather than a source of burnout. For memory, he highlights focused practice, sleep, errors, and self-testing; for smell, repeated attentive sniffing. On fertility, he discusses adequate calories, avoiding excess or very low body fat, low-sugar fermented foods, and possible roles for CoQ10 and L-carnitine, while warning testosterone therapy can lower sperm count. He links perimenopause hormone changes with anxiety, recommends discussing symptoms with a doctor, and advises preparing for surgery through fitness, rest, and circadian-friendly light. He closes by urging listeners to stay curious, avoid numbing distractions, build skills, and let passion emerge through experience.
