For skin elasticity, hydration, and joint support, this delivers 6,000 mg (6 g) of **Hydrolyzed Collagen** per serving — solidly within the 5-15 g clinical range studied for these benefits. Most skin-focused collagen trials show measurable improvements starting at 2.5-5 g daily, so this dose gives you a comfortable margin. The 90 mg of **Vitamin C** supports your body's own collagen production, since vitamin C is a required cofactor for collagen synthesis.

The collagen is hydrolyzed, meaning it has been broken down into smaller peptides for better absorption. What this means for you: the tablet format keeps the formula simple — just collagen and vitamin C with no fillers competing for space.

The tradeoff is pill burden: the serving size is 6 tablets daily. That is a lot of tablets to swallow, and it is the main practical barrier to consistent use. If you find that manageable, the dose and formula are well-suited for skin and joint goals. If swallowing 6 tablets feels excessive, a powder format may be easier to stick with long-term.
