Regenerative grass-fed whey protein isolate is rich in essential amino acids and boasts a high concentration of branched-chain amino acids (BCAAs)—Leucine, Isoleucine, and Valine (22.5g per 100g). These amino acids are critical for muscle protein synthesis and post-workout recovery. Whey isolate also delivers a strong dose of Glutamic Acid (17.1g), which plays a key role in muscle repair and immune support.
Additionally, whey protein isolate is highly digestible and rapidly absorbed, making it an ideal choice for those looking to maximize muscle gains.

Grass-fed beef protein shines in areas where whey isolate falls short. It contains a much higher Glycine (20g) and Proline (12g) content—key amino acids for joint, skin, and connective tissue health. Beef protein also features Hydroxyproline (10.2g), an amino acid found almost exclusively in collagen, making it an excellent choice for supporting overall structural integrity in the body.
This beef protein still comes with some BCAAs (8.4g total), which is not the case for regular collagen products, so it provides unique benefits of collagen PLUS the addition of a complete protein source. This makes it particularly valuable for those focused on joint health, injury prevention, and overall longevity.

If muscle growth is your top priority, regenerative grass-fed whey isolate seems to be the way to go. But if you’re looking for a protein that supports joint and skin health while still providing essential amino acids, and is dairy free, grass-fed beef protein is your choice.
Our personal take? Alternating both is natures ancestral wisdom. Our ancestors utilized all parts of the animal for a reason, because they each come packed with a variety of benefits.
