You're getting 1,000mg of **Vitamin C** per tablet — right in the middle of the clinically studied range (250–2,000mg) for immune support, collagen synthesis, and antioxidant protection. At one tablet daily, you're covered for a solid maintenance dose without approaching the 2,000mg upper limit.

The form here is standard ascorbic acid, which absorbs well at this dose level but starts to plateau around 1,000mg — your body will use most of it, but absorption efficiency drops if you take more. The 25mg of **Rose Hips** on the label is largely cosmetic at that amount, sitting at roughly 1% of the dose studied for any clinical benefit.

If you're looking for higher doses or better absorption at those levels, a buffered or liposomal form would serve you better. But at 1,000mg once daily for general immune and antioxidant support, this delivers what it promises at a straightforward dose.
