You're getting 1,000mg of **Vitamin C** per capsule — right in the middle of the clinically studied supplement range (250–2,000mg) and well above the 90mg RDA that only prevents deficiency. At this dose, you're covered for immune support and collagen synthesis, the two areas where vitamin C has the strongest research behind it. One capsule a day is all you need.
The form here is standard **ascorbic acid**, which is well-absorbed at this dose level but hits a ceiling — your body's absorption efficiency drops noticeably above 1,000mg per sitting. If you ever wanted to take more than one capsule, splitting doses throughout the day would help you absorb more of it. Buffered forms like calcium ascorbate are gentler on the stomach if you're sensitive.
At 1,000mg you're at half the 2,000mg tolerable upper limit, so there's room to increase if your needs call for it — though most people won't need to.
