For skin hydration and elasticity, this delivers 5g of **Hydrolyzed Marine Collagen Peptides** per scoop — the minimum effective dose from skin-focused clinical trials. Marine collagen (primarily Type I) is the form most relevant to skin, and hydrolyzed peptides are broken down for better absorption. At one scoop daily, you're at the clinical floor; two scoops would put you at 10g, firmly in the proven range.
**Hyaluronic Acid** at 60 mg (as sodium hyaluronate) gives you a moderate dose — clinical studies typically use 120–240 mg for skin hydration, so you're getting about half of what research supports. **Vitamin C** at 90 mg supports your body's own collagen synthesis, which makes it a functionally important addition even at this modest dose.
With 200 servings per container and no other ingredients listed, this is a stripped-down collagen product that keeps things focused. The main gap is the HA dose — if skin hydration is your primary goal, you may want to supplement the hyaluronic acid separately to reach clinical levels.
