What is the recommended protein intake?

To optimize health, particularly muscle health, Andrew Huberman and experts like Dr. Gabrielle Lyon and Dr. Mary Claire Haver, M.D. recommend aiming for around 1 gram of quality protein per pound of body weight, or lean body mass, per day 1 2. This intake may need to be higher for older adults, potentially 40-50 grams per meal, to stimulate muscle synthesis effectively 3.

Key Points:

• General Recommendation: 1 gram of protein per pound of body weight per day.
• Older Adults: May require more protein, up to 40-50 grams per meal, to maintain muscle mass.
• Quality Matters: High-quality protein sources rich in essential amino acids are important.
• Distribution: Total protein intake is the most critical factor, with even distribution across meals providing a slight additional benefit 4.

Always ensure to consult with a healthcare provider to personalize recommendations based on individual health needs and conditions.

The best protein sources, according to Andrew Huberman and his guests, include both animal-based and plant-based proteins:

Animal-Based Proteins:

1. Eggs: High in essential amino acids which are beneficial for skeletal muscle health.
2. Whey Protein: Contains a high ratio of leucine, crucial for muscle protein synthesis and repair.
3. Beef, Poultry, and Fish: These provide a complete amino acid profile similar to human muscle protein, making them highly effective for muscle maintenance and growth.
4. Organ Meats (e.g., Heart): Also high in beneficial compounds like CoQ10, which supports muscle health 1 2.

Plant-Based Proteins:

1. Soy Protein: Considered a complete protein with a PDCAAS (Protein Digestibility Corrected Amino Acid Score) of 1, meaning it provides all essential amino acids in sufficient quantities. Moderate consumption does not seem to affect testosterone or estrogen levels significantly.
2. Rice and Pea Protein Blends: These can be a viable option, especially when combined, to meet essential amino acid requirements.
3. Potato Protein Isolate: Has an amino acid profile similar to whey protein, though it is harder to find 3.

For vegans, ensuring adequate intake of key nutrients like B12, zinc, and iron is crucial, which may require careful dietary planning or supplementation 2.

The best protein supplements, as recommended by experts on the Huberman Lab, include both animal-based and plant-based options:

Animal-Based Protein Supplements:

1. Whey Protein:

   • Whey Protein Isolate: Ideal for those with lactose intolerance, as it contains very little lactose.
   • Whey Protein Concentrate: Contains alpha-lactalbumin, lactoferrin, and immunoglobulins which are beneficial for overall health 1.

2. Non-Animal Based Whey Protein: New developments have made it possible to produce whey protein from sources like yeast, providing a high-quality protein option for vegans 2.

Plant-Based Protein Supplements:

1. Soy Protein: A complete protein with a PDCAAS (Protein Digestibility Corrected Amino Acid Score) of 1, meaning it provides all essential amino acids in sufficient quantities. Moderate consumption does not seem to affect testosterone or estrogen levels significantly.
2. Potato Protein Isolate: Has an amino acid profile similar to whey protein, though it can be hard to find 2.

These supplements provide quality protein essential for muscle health and overall well-being. Always ensure to choose based on dietary preferences and any specific dietary restrictions or intolerances.
