Many beauty products contain collagen but won’t do much for your skin. Collagen molecules are too big to be absorbed through your skin. According to Collagen Supplement Research: “It simply stays on top of the skin and so that’s why there hasn’t been a single person who was ever used a collagen cream and seen a substantial difference in their skin because theoretically it’s impossible. Collagen needs to enter the bloodstream for it to effectively restructure your skin. That’s not possible with most creams because the molecules are too big to permeate the skin.”
To effectively get more collagen, you need hydrolyzed collagen powder. It basically gives you small chains of amino acids that are ready to go within your body. It’s easily digested and absorbed within minutes. “Instead of forcing your body to break down amino acids and then re-assemble those amino acids into collagen, hydrolyzed collagen skips that step. These hydrolyzed collagen supplements are typically made from high-grade gelatin (often extracted from cattle hides).” (source)
Scientific Evidence for Hydrolyzed Collagen
In a Japanese study, women took hydrolyzed collagen for 2 months and experienced 91% increase in skin hydration and elasticity. Another study showed dietary supplementation with collagen peptides improved appearance of cellulite.
In a study performed in France, women between ages 35 and 55 took 10 grams of hydrolyzed collagen daily for 12 weeks. By the end of the study, these women had experienced 41% less furrowing and fewer wrinkles. Their skin also resulted to be more hydrated and more resilient.
But hydrolyzed collagen is not only good for your skin, it also helps treat bone and joint diseases like osteoarthritis. According to Dr. Axe, “Multiple studies have showed collagen hydrolysate to be safe and to provide improvement in some measures of pain and function in men and women with OA or other arthritic conditions. Since cartilage is made up of collagen, it makes sense that supplementing with this building block could help the strength and framework of the cartilage itself.”
More Benefits of Hydrolyzed Collagen
Hormonal Balance: Lauren Geertsen explains that “of the amino acids in collagen hydrolysate and gelatin, 35% is glycine and 21% is proline and hydroproline. Also important, collagen hydrolysate/gelatin completely lacks the amino acid tryptophan. The high percentage of glycine and proline, as well as the lack of tryptophan, help balance the ingestion of large amounts of tryptophan and cysteine present in muscle meats. The equilibrium of amino acids play a large role in metabolic rate, thyroid function and hormone production.”
Weight Loss: “The purified, high-protein content of Hydrolysed Collagen is known to be an effective, natural appetite suppressant, in which many clinical studies have proven the satiating effect to promote weight loss. Additionally, unlike some weight-loss-promoting products, Hydrolysed Collagen contains no fillers, hormones, acids and is not produced with any forms of harsh processing that may affect the normal functioning of your body. Hydrolysed collagen has also proven to show a decrease in fats, avoiding clogging of the arteries and increased organ support.” (source)
