“High Quality L-Proline and Great Value”
This Nutricost L-Proline is exactly what I needed—clean ingredients, no fillers, and easy-to-swallow capsules. I appreciate that it’s non-GMO and gluten-free, making it a dependable daily supplement. The dosage is strong and effective, and the bottle lasts a long time. Excellent quality at a very fair price.

The unsung hero of collagen support—now in easy-to-swallow happiness pills
First Impressions Nutricost bottles always look like they mean business—clean label, zero nonsense. Crack this one open and boom: 180 capsules, 500mg each, serving size of two for a full 1000mg hit. Basically, collagen’s best wingman stuffed neatly in a plastic jug. Why I Like It L-Proline = collagen’s ride-or-die. Your skin, joints, and connective tissues need it, and unless you’re pounding bone broth 24/7, you’re probably not getting enough. Potent but manageable. 1000mg per serving feels just right—enough to matter without needing to choke down half a handful. Non-GMO and gluten-free. So I can pretend I’m a wellness influencer when really I’m just trying not to creak like an old wooden chair. Capsule Life 500mg per cap = not monstrous horse pills. Easy to swallow, no chalky aftertaste. Plastic bottle, standard flip-top—nothing fancy, but it does the job. Value You’re getting 90 servings in a single bottle. For the price, it’s like finding a coupon for your joints, skin, and tendons. Considering some “beauty” brands charge double for half the amount, this feels like stealing (the legal kind). Pros Solid 1000mg dose per serving. Clean formula—just what you need, no fillers. Capsules aren’t intimidating. 90 servings per bottle = lasts a while. Wallet-friendly compared to “glow-up” brands. Cons Serving size is 2 capsules—so if you hate swallowing pills, double the fun. Doesn’t come with collagen peptides built in—you’ll want to stack it. Bottom Line If you’re serious about joint health, collagen support, or just keeping the skin from crumbling like a day-old croissant, this is a no-brainer. Nutricost kept it simple and nailed it.

Repair mitochondria
I read that proline can help your cells repair mitochondria. (I had a long course of doxycycline for cat scratch disease and not too long ago I found out it can impair your mitochondria). I started taking four grams mornings on an empty stomach and it did seem to raise my energy levels after a week or so. Also read proline can help your cells repair DNA damage.

I believe in science
I’m not a doctor and do not give a medical advice. I bought this supplement after reading the article because I believe in science and hope it will reduce risk of cardiovascular issues in my future According to article “Reducing the risk for cardiovascular disease with nutritional supplements” Matthias Rath Journal of Orthomolecular Medicine 7, 153-153, 1992 …”The amino acids L-lysine and L-proline competitively interfere with the binding of lipoprotein-a to constituents of the vascular wall and atherosclerotic lesions. The therapeutic use of these amino acids could prevent further buildup of lipoprotein-a accumulation in the vascular wall. More importantly, optimum concentrations of L-lysine and L-proline could release deposited lipoprotein-a but also other atherogenic lipoproteins from the vascular wall….”

Ordered by Doc
My Provider started me on L-Proline and L- Lysine for elevated alpha lipo protein a “ little a” years before there was an approved drug for it. My numbers dropped drastically after a couple of months. The product I used in past was difficult to swallow. These capsules are so much easier. Do not take without talking to your Health Care Provider.

Hola lo pedi porque he bajado mucho de peso, por un padecimiento y tengo la piel resecaa, comence ha sentir algo muy raro en mi cabeza (mi cerebro), y hace 2 dias vi que tenia un sabor raro en mi boca, pense que la sopa se habia hechado a perder, y mi orina huele desagradable, ademas despues de comer sudo mucho, yo pense y le echaba la culpa a un antidepresivo que me tomo por la mañana, pero, hoy me tome primero la prolina con la glicina y la vit.C y comence con estos sintomas, llegue tarde y hasta entonces me acorde del antidepresivo, me puse a investigar de los aminoacidos y resulta que si no metabolizas la prolina, te da mas depresion, tal vez sea un excelnte producto para quien lo asimila bien, hoy fue mi ultimo dia de tomarmelo, gracias por su atencion
