Andrew Huberman explains late-night Alpha-GPC workouts, morning daylight, fertility, memory training, and finding your passion.

In this Huberman Lab listener Q&A, Andrew Huberman says late-night exercisers can try 600–900 mg of Alpha-GPC for focus without caffeine’s sleep disruption, but suggests limiting use to a few times weekly and pairing it with garlic because of potential TMAO concerns. After training, a hot shower, long-exhale breathing, and a modest protein-and-carbohydrate snack may help with winding down and recovery. He says morning ambient daylight helps set circadian timing even when viewed facing west, and advises adapting health routines to real-life constraints rather than pursuing perfection. For memory, he emphasizes focused learning, sleep, making effortful mistakes, and self-testing; for smell, deliberate repeated sniffing of distinct odors. On fertility, he discusses balanced calorie intake, low-inflammation foods, fermented foods, and CoQ10 and L-carnitine, while warning that testosterone therapy can suppress sperm count. He also connects perimenopause-related anxiety with changing hormones, recommends discussing symptoms with a clinician, favors a sunset wedding for guests’ schedules, and advises preparing for surgery through fitness, rest, and circadian-friendly light. He closes by urging curiosity, steady work, and skill-building to discover and develop a passion.
