One older study found improvements in hair growth among people with androgenetic alopecia who took a gelatin-cystine supplement. In a study on human cancer cells in test tubes, gelatin from pig skin reduced growth in cells from stomach cancer, colon cancer and leukemia ( 31).

Collagen peptides are a more recent invention, optimized for drinking with water or other liquids instead of cooking. If you have brittle nails, collagen is definitely worth a try. 7. Appetite Reduction and Possible Weight Loss Lis DM, Baar K. Effects of Different Vitamin C-Enriched Collagen Derivatives on Collagen Synthesis. Int J Sport Nutr Exerc Metab. 2019;29(5):526-531. View abstract. This is thought to contribute to common gut conditions, such as irritable bowel syndrome (IBS). It Could Reduce Liver Damage You can’t get hydrolyzed collagen from home cooking unless your kitchen contains an entire chemistry lab. But considering that they’re probably equivalent for most people, getting more gelatin is likely to give you the same results. Here’s how to get it:Shaw G, Lee-Barthel A, Ross ML, Wang B, Baar K. Vitamin C-enriched gelatin supplementation before intermittent activity augments collagen synthesis. Am J Clin Nutr. 2017;105(1):136-143. doi:10.3945/ajcn.116.138594 The proteins in gelatin can help support the intestinal wall, including building the protective mucus lining in your intestines. In early studies on rats, gelatin helped protect the lining of the intestines from damage, although further research is needed to fully confirm this effect in humans. A 2019 meta-analysis of five high-quality oral collagen peptide studies found they decrease osteoarthritis pain according to two different measures[ *].

For some people, the difference in taste of gelatin vs. collagen makes collagen supplements a more appealing option. However, adding powdered gelatin supplements to drinks or smoothies can help mask the flavor and make it much more tolerable. This study doesn’t fully answer the question of whether collagen protein offers additional recovery benefits when combined with whey or other complete proteins, but we do know that it can reduce joint pain in hard-training athletes. Djagny VB, Wang Z, Xu S. Gelatin: a valuable protein for food and pharmaceutical industries: review. Crit Rev Food Sci Nutr 2001;41(6):481-92. View abstract. Gelatin is produced by processing animal parts to extract the collagen and turn it into gelatin. This flavorless, translucent substance has a jelly-like texture. Both collagen and gelatin have similar proteins, and they may provide similar benefits. Noma, T., et al. (2017). Effects of dietary gelatin hydrolysates on bone mineral density in magnesium-deficient rats.Starting at about age 35, your collagen production naturally begins to slow. By age 40, collagen begins to deplete faster than your body can reproduce it. By age 60, over ½ of your body’s collagen has been depleted. 3 In addition to aging, other factors impact collagen levels, including genetics, smoking, pollution, excessive sun exposure, and nutritional deficiencies. Health Benefits of Gelatin & Collagen Collagen is a special type of protein high in the amino acids glycine, proline, hydroxyproline, alanine, and arginine. In fact, compared to other proteins, it has 10-20 times more glycine and proline[ *]. Sustained adherence, hypoallergenic, non-pyrogenic, non-toxic, fluid control, impermeable to exogenous microorganisms, absorbs exudates, on shelf biomaterial, ease of application, and cost effective. It’s believed that our ancestors obtained more collagen and gelatin than most people eating a “modern diet” do today because they frequently consumed traditional bone broths made with connective tissues, tendons, and other odds and ends of animals that are naturally rich in these substances.

While it hasn’t been proven to be a helpful fat loss tool, it seems capable of increasing satiety hormones like leptin and lowering appetite hormones like ghrelin in obese adults. Nutrition Facts While eating parts of animals that contain collagen and consuming bone broth are both ideal ways to obtain gelatin and collagen, this isn’t always easy or possible. As an alternative, you can use powdered gelatin.

Most protein powders hold these nine essential amino acids in varying amounts. Any protein that has all nine is called a complete protein. Lewis CJ. Letter to reiterate certain public health and safety concerns to firms manufacturing or importing dietary supplements that contain specific bovine tissues. FDA. Available at: www.cfsan.fda.gov/~dms/dspltr05.html.

Normally, your body makes its own collagen using amino acids from the protein you eat, not necessarily from the collagen contained in food sources. The nutrient content of the remaining 1–2% varies, but consists of water and small amounts of vitamins and minerals like sodium, calcium, phosphorus and folate ( 9). However, although the two share similarities, many people are unsure about what factors distinguish collagen vs. gelatin and which one is a better option. Inoue, N., et al. (2016). Ingestion of bioactive collagen hydrolysates enhance facial skin moisture and elasticity and reduce facial ageing signs in a randomised double-blind placebo-controlled clinical study. If you don’t have time to make your own, then it can also be bought in sheet, granule or powder form. Pre-prepared gelatin can be stirred into hot food or liquids, such as stews, broths or gravies.

Here’s an explanation of what gelatin and collagen are, the difference between them, and why they’re important, plus simple ways to get more of them in your own diet. Gelatin and Collagen: Missing Pieces in the Modern Diet Collagen and gelatin have gained notoriety for easing symptoms of osteoarthritis and rheumatoid arthritis. Osteoarthritis is common in older people and considered the leading cause of frequent joint pains. As people age, they tend to develop more stiffness, aches and limited mobility that worsen over time since collagen continues to break down and erode. Lastly, just 2.5 grams per day of collagen peptides can improve the appearance of cellulite (and other skin health markers), according to a trial of 105 women between the ages of 24-50[ *]. 3.
