Collagen Peptide as a Protein Source

Collagen peptides are used extensively as a protein source in everyday foods, sports nutrition and medical care products. Given that the Recommended Daily Allowance for protein is 0.8g per kilogram of body weight, protein supplementation has become more crucial to our diets, especially for the elderly.

Research suggests that the elderly should consume 1.5g of protein per kilogram of body weight to maintain optimal health (Wolfe RR,Miller KB. Optimal protein intake in the elderly.2008 Oct;27(5):675-84.). These protein requirements can be challenging to achieve, and many rely on protein supplementation to help maintain lean muscle mass as they age.

In a published clinical study, researchers examined the effects of a fortified collagen supplement peptide supplement and a whey protein supplement on lean muscle mass and nitrogen balance in the elderly (Hays NP1, Kim H, Wells AM, Kajkenova O, Evans WJ. J Am Diet Assoc. Effects of whey and fortified collagen hydrolysate protein supplements on nitrogen balance and body composition in older women.2009 Jun;109(6):1082-7. doi: 10.1016/j.jada.2009.03.003). This study indicated that:

  • The collagen peptide group had less nitrogen excretion than the whey protein group, indicating that collagen peptides promote healthy nitrogen balance.
  • The collagen peptide group showed no change in body mass, while the whey protein group experienced a decrease in body mass, suggesting a potential decrease in lean muscle mass.

This research exemplifies that lean muscle mass can be retained through protein supplementation with collagen peptides. Wellnex collagen peptides can be included in a variety of applications, such as liquid concentrates and powders, to meet consumers’ protein needs.

Our Peptide Amino Acid Profiles

Wellnex collagen peptides have an effective amino acid profile and unique di-peptides to help stimulate collagen synthesis in humans. Collagen peptides contain 8 of the 9 essential amino acids. With high proportions of hydroxyproline-containing peptides, Wellnex collagen peptides are ideal for skin, joint and bone health.
