## Summary

Andrew Huberman hosts exercise physiologist and nutrition scientist Dr Stacy Sims for a deep dive into female-specific training and nutrition across the lifespan. Sims argues that much mainstream fitness advice (fasted training, delayed post-workout eating, zone-2-heavy programmes) is generalised from male data and can undermine lean mass, recovery and metabolic health in women—especially from the mid-40s as estrogen flux declines in perimenopause. She recommends fuelling before training (around 15 g protein, with carbohydrate added for longer cardio), then a leucine-rich protein bolus soon after: about 35 g within 45 minutes for reproductive-age women and 40–60 g for perimenopause onward, because anabolic resistance rises with age. She frames estrogen as a key anabolic/driving signal for strength and power; when it flattens, heavy lifting (low reps in reserve), sprint/polarised work and higher protein become more important than endless easy cardio. Soft-tissue issues common in the mid-40s (e.g. frozen shoulder) are linked to this transition. On supplements she elevates creatine monohydrate (about 3–5 g/day) for muscle, mood/brain and gut support ahead of most other products. The episode is long-form science communication rather than a collagen brief, but it is the highest-reach female-physiology nutrition conversation on YouTube and anchors the oral-protein story Ovitage sits beside.

## Key claims (with timestamps)

- **[00:22:58]** ~15 g protein before training helps fuel and raise EPOC.
- **[00:27:33]** Reproductive-age women ~35 g leucine-oriented protein within 45 min post-training; perimenopause onward 40–60 g due to anabolic resistance.
- **[00:28:19]** Women’s metabolic recovery window is tighter (~60 min) than men’s (up to ~3 h); ‘no anabolic window’ claims are male-data based.
- **[01:53:11]** Creatine is her number-one supplement for women—muscle, brain/mood and gut; ~3–5 g monohydrate daily.
- **[00:45:55]** Perimenopause (mid-40s–early 50s) is a definitive ageing inflection; soft-tissue injuries and need for heavy/polarised training rise.

## Exact quotes

- “Women who are in their reproductive years need around 35 gram of good protein, high quality leucine oriented protein within 45 minutes.”
- “Women who are perimenopausal onwards are 40 to 60 g because we become more anabolically resistant to food and exercise as we get older.”
- “The number one is creatine.”

## Relevance to Ovitage

Strong alignment with Ovitage’s oral protein/BCAA story for peri/post-menopausal women: higher protein dose, leucine signalling, protection of lean mass, and brain-fog/mood adjacency via creatine and protein timing. Does not discuss collagen peptides specifically; Ovitage should not be positioned as replacing complete dietary protein or heavy strength training—Sims would treat collagen as at best additive to those foundations.

## Weak / lightly evidenced medical claims to flag

- Creatine ‘gut health’ benefit stated briefly without detail—evidence for creatine and gut is thinner than for muscle/cognition.
- Exact protein gram targets are practitioner heuristics synthesised from literature, not a single RCT prescription for every woman.
