You're getting 5g of **Marine Collagen Peptides** per scoop — the minimum clinical dose where skin elasticity and hydration benefits start appearing in research (2.5–10g range). Fish-sourced collagen is naturally rich in Type I, the type most relevant to skin. If you're targeting joint support, you'd want to double the serving to reach the 10–15g range studied for that goal.

**Vitamin C** is included at 90mg as calcium ascorbate — a well-absorbed, stomach-friendly form. This matters because your body can't synthesize collagen without vitamin C as a cofactor, so having it built into the formula means one less thing to worry about. The 60mg of **Hyaluronic Acid** adds skin hydration support, though most studies showing visible results used 120–200mg daily, so you're getting about half the studied dose.

The main limitation is that everything here is dosed at the lower end of clinical ranges. At one scoop daily, this covers the basics for skin support, but if you're looking for stronger results — especially for joints — you'd need to increase your serving size, which also means going through the container faster.
