The takeaway

Solid pick. Vitamin C has real research behind it (20+ studies reviewed), but Proprietary doesn't have enough studies yet.

Based on the ingredients we could read from this scan. A full label may include more — like added sugars, colorings or other ingredients — than we captured here.

Missing some ingredients or nutrients?

This grade is built from the label data we could match for this product, so parts of it — like the full nutrition panel — may not appear here yet. A grade is only as sharp as the label we can actually read, and it gets better every time someone shares a clear photo of the real product. Rescan the ingredients and nutrition facts and we'll sharpen it.
