Your Top Health Questions Answered

Video summary

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

In this Huberman Lab Q&A, Andrew Huberman offers practical, science-based answers across health and life decisions. For late-night training, he suggests 600–900 mg Alpha-GPC sparingly, paired with 600 mg garlic because of possible TMAO and cardiovascular concerns, plus a hot shower, physiological sighs, and post-workout protein or oatmeal to support sleep. He explains that any ambient daylight within the first hour of waking helps circadian timing—even from a west-facing balcony—while morning light over the previous 2–3 days shapes the body clock. He warns against protocol overwhelm, prioritizing sleep, hydration, exercise, nutrition, social connection, and consistency. Memory improves through alertness, focused learning, deliberate errors, sleep, and self-testing; smell through repeated, attentive sniffing. Fertility guidance emphasizes healthy body fat, low-inflammation foods, fermented foods, and caution with testosterone therapy. He also addresses perimenopause anxiety, surgical recovery, and passion as the result of curiosity, structured effort, and mastering fundamentals before adding a personal signature.
