Each scoop provides 6.6 g of **hydrolyzed collagen** (Types 1 and 3) from bovine sources, landing within the clinically studied range of 5-20 g per day. At this dose, you are in the range where randomized trials have observed improvements in skin elasticity and hydration — most skin-focused studies show benefits starting at 2.5 g per day. Hydrolyzed means the collagen proteins have been broken into smaller peptides that your gut can absorb more efficiently than intact collagen or gelatin.
Types 1 and 3 are the most abundant collagen types in your skin, bones, tendons, and ligaments. Type 1 alone makes up about 90% of your body's total collagen. The bovine source is well-studied and provides both types in a ratio similar to what your body naturally produces. The ingredient list contains nothing else — no sweeteners, no flavoring, no additives — so you are getting collagen and nothing more. The powder format lets you mix it into water, coffee, or smoothies, and dissolving it in liquid can support absorption.
One thing to keep in mind: your body needs **vitamin C** to actually build new collagen fibers. Vitamin C activates the enzymes that cross-link collagen into its functional structure. This product does not include vitamin C, so if your diet is low in fruits and vegetables, pairing it with a vitamin C source will help you get the most out of your collagen intake.
