Absorption of Collagen Peptides Study
Monocentric, randomized, cross-over study; 4 healthy males (aged 41 ± 13 years) with a body weight of 59 ± 4 kg; Single Dose Study.
Results: Collagen tripeptide (CTP), CTP-100 and CTP-50- formulas containing approximately 100% and 50% tripeptides respectively- were shown to be absorbed more efficiently and in greater amounts than standard collagen peptide (CP) of higher molecular weights. These smaller tripeptides also remained longer in the body before being excreted, suggesting an enhanced bioavailability. These results support the use of low-molecular-weight collagen peptides like those in our formula to help improve skin hydration, elasticity, and overall appearance.*
Low-Molecular-Weight Collagen Peptide (LMWCP) Improvements in Human Skin Study*
Randomized, Double-Blind, Placebo-Controlled Study; 53 healthy females (aged 40-60 years) with photoaged skin; Used daily for 12 weeks.
Randomized, Double-Blind, Placebo-Controlled Study; 53 healthy females (aged 40-60 years) with photoaged skin; Used daily for 12 weeks.
Effects of Collagen Tripeptide Supplement on Skin Properties Study
Prospective, randomized, controlled open blinded assessment trial; 32 healthy volunteers (24 women, 8 men) aged 30-48 years; Used for 12 weeks.
Results: The groups that took collagen (with or without vitamin C) showed better skin hydration and elasticity compared to the control group.* The collagen groups also had less water loss from the skin (TEWL).* Participants who took collagen reported the highest satisfaction with their skin improvements.*
