## Description

Full description not available

## Features

- L-Lysine is one of 9 essential amino acids that cannot be made in the body. It is the basic raw material for carnitine synthesis. L-Proline can be made in the body, but low-protein/vegetarian diets may not always promote optimal L-proline production. L-Lysine and L-proline amino acids are the precursors of hydroxylysine (HL), and hydroxyproline (HP), two constituents of collagen.
- Suggested Use: 2 to 4 tablets daily with meals.
- Suitable for vegetarians. Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, salt, preservatives, or artificial color, flavor or fragrance.

## Questions & Answers

**Q: Where are they made**
A: Please ask the manufacturer.

**Q: Why does the label say 550mg, but the ingredient facts says 1.1 gram?**
A: 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.

**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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Improve clogged arterite!
*by R***. on February 26, 2023*

Product on US market years ago faded out - Vitacore. The US proponent was Dr. Linus Pauling who passed on. He had a business partner in Europe who still sells Vitacore. Here in US you can get same thing from Amazon or Vitamin Shoppee - discount catalog. Proline + Lysine pills,- BUT HAS 1000MG of Vit C. See back label. SAME AS VITACORE. It was also originally available as orange powder drink . US Patented and tested as OK and works. Think of the water pot on stove with lime caked up . Add water and vinegar without stirring. After a while the pot is cleaner. The Proline + Lysine erodes away very slowly the Plaque build up in arteries from Cholesterol and fat. The autonomic process in body has no personal control. It constantly heals and adds collagen to arteries . If not enough collagen, process uses fat and cholesterol on surface of arteries. Poor diet. Takes a few weeks to feel better. A start of clearing on medial scan within 3 months. Full process takes a year constantly on pills. The Vit C allows body to MAKE collagen as well as from the food. So now you know. There was a movie years ago with Harrison Ford that was a put down on such a product. Producers of " The Fugitive" made it out as non worthy - they called it Provassic.

### ⭐⭐⭐⭐⭐ Great Stuff!
*by B***B on May 21, 2019*

I've been taking this stuff almost two years. They are horse pills, but easy enough to swallow. I take two in the morning, and two in the evening. I began using it after having an ischemic stroke (cholesterol blockage). After a year, my doc took me off the statin, and my LDL is still going down. I've had knee and hip issues for years...getting out of a seat was not fun, squatting was impossible, even walking was painful. I now, simply stand up from a chair, sofa, etc; I can do squats with/without weights again, and no issues/pain walking. I've even started running again. My wife's sister and a couple of friends have tried it, and report similar results. It does take a couple months to start noticing improvement, so bear with it.

### ⭐⭐⭐⭐ Trips to the Bathroom as an Older Male
*by W***. on March 29, 2025*

Good price and quality for a water based vitamin C with l-lysine / Linus Pauling type formula. Extra bonus additives in the formula for vascular health.As an older male I had to give this up for a fat based vitamin C as I had to go to the bathroom all of the time from the water based vitamin C.PS get your calcification checked as this does not address that issue.
