Why does the label say 550mg, but the ingredient facts says 1.1 gram?

This product contains the same ingredients and quantity as the famous earlier Patented one called Vitacore . The Source Naturals bottle has same wt tablets each, so as 4 tablets contain 1 gram Vitamin C and ALSO 1.1gm Proline and also 1.1Gm of Lysine, and other minerals as listed on bottle together. The quantity is correct as per the earlier version Vitacore. The LABEL reflects the total only of Proline + Lysine of 2200mg divided by 4 tablets = 550mg. Company is eliminating legal matters as with the earlier Vitacore, and The Vit C is only on back label.

what color are these? The ones I just got had a broken seal and they are speckled brownish.

"Speckled brownish" is an accurate description for the natural color of these Proline-Lysine tablets.

Does this help improve your skin? Thanks!!

I didn't notice a difference in my skin. I mainly use it for improved circulation in my legs.
