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. **Q: what color are these? The ones I just got had a broken seal and they are speckled brownish.** A: "Speckled brownish" is an accurate description for the natural color of these Proline-Lysine tablets. **Q: Does this help improve your skin? Thanks!!** A: I didn't notice a difference in my skin. I mainly use it for improved circulation in my legs. ## Frequently Bought Together - Source Naturals Proline & Lysine, 550 mg - 120 Tablets - NOW Supplements, NAC (N-Acetyl Cysteine) 600 mg with Selenium, 250 Veg Capsules - NOW Foods Supplements, Glycine 1,000 mg Free-Form, Neurotransmitter Support*, 100 Veg Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/14712161-proline-and-lysine-550-mg-120-tablets](https://www.desertcart.com.cy/products/14712161-proline-and-lysine-550-mg-120-tablets) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-23*
