Promix Clean Grass-Fed Collagen Supplements

Whether you’re a professional athlete focused on reducing recovery time, or simply looking to improve your overall health, collagen supplements can help support your goals.

At Promix, we take pride in offering the cleanest collagen protein powder supplements free from artificial ingredients or processing aids during production. The peptides used in our collagen supplements are sourced exclusively from grass-fed Brazilian cattle and third-party tested for safety.

What are Collagen Peptides?

Collagen is an essential protein found in the connective tissue, ligaments, bone, and skin. In our mid-to-late 20s, our natural collagen supply starts to decline. A collagen deficiency can lead to several physiological responses, including:

  • Joint pain, stiffness, and inflammation
  • Increased risk of osteoarthritis
  • Muscle weakness
  • Decreased bone density
  • Loss of skin elasticity and hydration
  • Increased signs of skin aging 
  • Brittle nails, thinning or damaged hair
  • Prolonged recovery time after physical activity
  • Loss of strength and elasticity in arteries, leading to possible heart conditions

Adding a collagen supplement to your daily routine can help avoid the health risks associated with a collagen deficiency. Promix collagen supplements can help rebuild the collagen required to properly support joint, bone, skin, and connective tissue function and reduce recovery time.
