Collagen vs gelatin for arthritis10/19/2023 Collagen is considered to be one of the most useful biomaterials. The word collagen originates from a Greek word that kola means gum and gen means producing. We continually update and medically review our information to keep our content trustworthy, accurate, and reliable. Introduction Collagen, an important protein produced by the body, is the main structural protein found in the skin, tendon, and bone. All of our content is reviewed by medical doctors and doctoral-level experts in pharmacology, toxicology, and chemistry. On evolving topics, studies from pre-print journals may be sourced. These sources include peer-reviewed studies and information from agencies such as the FDA and USDA, and the National Academy of Medicine. In addition the results of its expert testing, ConsumerLab uses only high-quality, evidence based, information sources. Stop taking collagen before certain bone-related blood tests. People with allergies to specific sources of collagen (such as fish) should avoid collagen products derived from these sources. Collagen supplements safety and side effects:Ĭollagen supplements are generally well-tolerated, but mild side effects including gastrointestinal symptoms, headache, dizziness and rash can occur.However, there are some supplements that contain certain vitamins, amino acids, and other ingredients used in building collagen. There is no "vegan collagen," as plants do not produce collagen. Collagen may be taken with or without food. Dosing with UC-II, a cartilage-based product, is much lower. Typical daily dosage of hydrolyzed collagen is 1 to 10 grams. In addition to passing tests for quality, these products contained brands used in clinical studies that suggest benefits and, for powders, had superior taste when mixed in liquid. A cartilage-based product contained a much smaller amount (10 mg) but this is appropriate for that particular ingredient (see What CL Found).Īmong the products Approved in testing, ConsumerLab selected a Top Pick for skin (wrinkles) and a Top Pick for joint pain. What did CL's tests of collagen supplements find?ĬonsumerLab's tests showed that products contained their expected amounts of collagen, ranging, per daily serving, from about 2.9 grams to 20 grams among powders, and from 1.8 grams to 6 grams for tablets and capsules.These effects can require two to six months of daily use (see What It Does). It may also modestly improve joint pain and/or flexibility in osteoarthritis, help with tendons, and possibly help with the treatment of pressure ulcers, burns, and bleeding gums. Gelatin also contains collagen, but is not soluble in cold water (see What It Is).Ĭollagen appears to modestly reduce wrinkles and slightly improve the appearance of cellulite. The specific composition of these "collagen hydrolysate" or "collagen peptide" products can vary somewhat depending on how they are hydrolyzed (which typically involves heat and enzymes). Collagen in supplements is typically hydrolyzed, i.e., broken down to amino acids and/or chains of amino acids (peptides) to improve absorption as well as the ease with which it mixes into liquids, such as cold water. It uniquely contains the amino acid hydroxyproline, along with other amino acids. Collagen is a type of protein found in the skin (types I and III collagen), joints (type II collagen) and other parts of the body.
