Does anyone here use collagen supplements? Bodybuilders in past like Steve Reeves were big on taking collagen in (beef) gelatin form.
Back in the 50's. hen Bruce Randall dieted down from 400 lb to 223 lb and win the Mr Universe. I wonder whether his intake of collagen(specifically gelatin) might have helped preserve skin elasticity and avoid looseness and sagginess.
............Some of the evidence looks promising:"Oral supplementation of specific collagen peptides has beneficial effects on human skin physiology: a double-blind, placebo-controlled study.
........
At the end of the study, skin elasticity in both CH dosage groups showed a statistically significant improvement in comparison to placebo. After 4 weeks of follow-up treatment, a statistically significantly higher skin elasticity level was determined in elderly women. With regard to skin moisture and skin evaporation, a positive influence of CH treatment could be observed in a subgroup analysis, but data failed to reach a level of statistical significance. No side effects were noted throughout the study."

Results
RESULTS:
Oral collagen peptide supplementation significantly increased skin hydration after 8 weeks of intake. The collagen density in the dermis significantly increased and the fragmentation of the dermal collagen network significantly decreased already after 4 weeks of supplementation. Both effects persisted after 12 weeks. Ex vivo experiments demonstrated that collagen peptides induce collagen as well as glycosaminoglycan production, offering a mechanistic explanation for the observed clinical effects."
CONCLUSION:
The oral supplementation with collagen peptides is efficacious to improve hallmarks of skin aging."

The study presented here provides evidence that ingestion of Pure Gold Collagen can reduce the signs of aging. A larger in vivo study is needed to confirm the antiaging effect of this supplement. Additional in vitro studies will also help us to understand the potential mechanism of action of this nutritional antiaging supplement."
