Many people include collagen peptides in their supplement routine because of their benefits for the skin, joints, and connective tissue. They come in many different forms, and users can choose everything from premium marine collagen peptides to grass-fed ones. However, not all peptides are created equal. Quality varies, which affects how well the supplements are absorbed and, ultimately, how effective they are. Here are the reasons why the type you use matters.
The Source Affects Absorption, Taste, and Smell
Collagen peptides can be derived from several different sources, but most on the market are likely to come from bovine or marine sources. Bovine collagen is taken from cow hides, while marine collagens are extracted from the scales of fish. Both are rich in type I collagen, which is good for your skin and joints. Bovine collagen also typically contains type III collagen.
The molecular size of marine collagen is smaller, which means that it is better absorbed by the body. However, the source of the collagen affects the flavor, smell, and allergy risk of the products that use it. Premium marine collagen peptides tend to have the fish smell and taste removed to make them more pleasant.
Molecular Weight Also Affects Absorption
When you purchase collagen peptides, you should be provided with the molecular weight, measured in daltons. The lower this is, the smaller the peptides should be, which helps your digestive system absorb them more quickly. Premium products tend to weigh between 2,000 and 5,000 daltons, helping them to reach your bloodstream and stimulate your body’s collagen production process faster.
It is possible that a lower dose of smaller peptides may be more effective than a higher dose of large ones that cannot be absorbed as well. Be wary of collagen powders and other products that do not list the molecular weight. Results from these are likely to be inconsistent.
Some Products Are Purer Than Others
As you are going to be ingesting your collagen supplements, it is sensible to make sure they are as pure as possible. While being processed, they can easily become contaminated with heavy metals, pesticides, or residue from solvents. Where possible, look for suppliers whose products are purity tested and verified by third parties.
Also, take care to avoid products that are sweetened or which contain many filler ingredients. If you are supplementing with collagen for health or cosmetic reasons, these may undermine your goals.
Sourcing Collagen Impacts the Environment
Modern consumers are growing increasingly concerned about the environmental impact of the products they buy. You can leave a greener footprint when buying collagen peptides in several ways.
First, look for suppliers who use byproducts of other industries that would otherwise be thrown away. Many marine collagen suppliers operate this way. Secondly, look for suppliers who use wild-caught fish or free-range cattle. Brands that do this are often open and transparent about their sourcing. Some also carry eco-friendly certificates from third-party organizations.
Collagen peptides vary in several ways, and there are some important differences between them. Premium marine collagen peptides can have very different results from affordable bovine ones, so it’s always worth doing your research.
