Summary
In this premium AMA episode, Andrew Huberman answers listener questions about protein supplementation, comparing whey protein and collagen/bone broth across different health goals. He explains that whey protein is superior for muscle protein synthesis and recovery due to its high leucine content and bioavailability, while collagen protein (and bone broth) has distinct advantages for skin elasticity and appearance at doses of approximately 15 grams per day. Huberman recommends getting about 1 gram of quality protein per pound of body weight daily, with 60-70% from whole food sources and the remainder from supplements like whey.
The episode also addresses a nuanced downside of whey protein: its high leucine content can increase mTOR signaling, which in some individuals -- particularly women at certain phases of their menstrual cycle -- may exacerbate acne. Huberman recommends a self-experimentation approach: if experiencing acne, try removing whey protein for a few weeks to assess whether it is a contributing factor. He emphasizes that bone broth and collagen protein serve complementary rather than competing roles to whey protein, and that the ideal strategy is to use both types depending on specific health objectives.
Key Points
- Whey protein is superior to collagen/bone broth for muscle protein synthesis due to its high leucine content and bioavailability
- Collagen protein at ~15 grams per day has been shown to improve skin elasticity and appearance in studies over 2+ weeks
- Aim for approximately 1 gram of quality protein per pound of body weight daily, with 60-70% from whole foods
- High leucine content in whey protein can increase mTOR signaling, potentially exacerbating acne in some people -- especially women at certain menstrual cycle phases
- Bone broth and collagen protein serve complementary roles to whey and should not be viewed as replacements for high-quality protein sources
- If experiencing acne issues, try eliminating whey protein for a few weeks as a self-experiment to identify whether it is a contributor
Key Moments
Whey vs. collagen protein: when to use each for muscle and skin
Whey protein is superior for muscle protein synthesis due to high leucine content, while collagen at ~15g/day improves skin elasticity. Aim for 1g protein per pound of body weight daily. High leucine in whey can exacerbate acne in some people via mTOR signaling.
"Whey protein is going to be far superior for purposes of muscle protein synthesis and for recovery from exercise."
