Yes — vitamin C is required for collagen synthesis, which is why many collagen products already include it. Collagen is typically taken for skin elasticity, joints, hair & nails (marketed), while Vitamin C is used for antioxidant, immune support, collagen synthesis — different jobs, so people often end up with both in the cabinet.

For context: a typical daily amount of Collagen is 2.5–15 g, and Collagen has no formal upper limit (generally safe). A typical daily amount of Vitamin C is 75–90 mg, and the upper limit for Vitamin C is 2,000 mg.

• Vitamin C:High doses raise iron absorption — caution in hemochromatosis.
• Vitamin C:Very high doses may cause GI upset or kidney stones in susceptible people.
