## Overview

NOW Foods Sports Nutrition Arginine & Ornithine delivers a potent 2:1 amino acid blend (500 mg Arginine, 250 mg Ornithine) designed to enhance protein metabolism, support urea detoxification, and promote vascular health. Manufactured in the USA under strict GMP A-rated standards, this clean, filler-free formula is trusted by athletes and fitness enthusiasts to boost nitric oxide production, improve workout pumps, and stimulate natural growth hormone release for recovery and anti-aging benefits.

## Description

Arginine & Ornithine combines two complementary amino acids in one convenient supplement. Arginine is required for proper elimination of urea from the body, which occurs through a critical metabolic cycle that detoxifies the body of nitrogen compounds that are normal by-products of protein metabolism.* Ornithine is synthesized from arginine and is a precursor of citrulline, proline and glutamic acid.* Both of these amino acids are popular with athletes and other active individuals.Other Ingredients: Capsule and Magnesium Stearate (vegetable source).

Review: EXCELLENT SUPPLEMENT FOR EVERYONE - the combination of both Arginine & Ornithine in a 2 to 1 ratio is extremly powerful I suffered from 20+years of preiphreial artey disease- my veins bulged out and very painful even to walk , but these supplements cured my problems 100% when moderm medicine couldnt. IN ADDITION this combination when taken at bed time will activate your pituitary gland ( it shrinks by 1%every year after age 30- this is 1 of the reasons why we show signs of aging)but this stimulates and makes the gland grow and it produces Human Growth Hormones, ALSO it helps stimulate new growth in your organs, heart,liver etc ALSO it relaxes your blood vesels as to prevent hardening of the arties thruought ur body. Many people take this just to get off blood pressure medicine and report a drop in 30pts or more- of course this is with a good diet. I always trusted the NOW brand and havent been dissapointed , we all need to look to supplements and alternatives to modern medicine cause they only provide band aids not solutions Please for refrence stay away from High Fructose Corn Syrup , its in many,many products- read the label people from soda, fast food,ketchup,ice cream,pickles, most sweets etc It tells the brain your not full and u keep eating and drinking more of it.Your body cant digest it and it sits on top of liver causing fatty liver disease,cirrocis,diabetes etc etc check out naturalnews dot com its a wealth of information
Review: Great for vascularity & workout pumps - Love this supplement! Been taking last couple months 30-60 mins before my workouts, weights and cardio! I am a 25 year old female, 5’3” 115 lbs and I take two a day, I have tried three but didn’t notice much of a difference. I have noticed that although this supplement gives me great pump on certain occasions it has made me fatigued quicker during my weight training sesh... my thought on this is I had such a great pump that I lifted to my maximum and became fatigued quicker as a result... but this has only happened on a couple occasions while using this. My veins on my arms are looking awesome lately I am really impressed, I don’t hear to many ladies out there looking to gain big veins but I find it attractive and an attribute of being physically fit! This supplement has helped me consistently bump up my weights in the gym after being stuck on a plateau for quite some time not able to lift heavier. I would definitely recommend this to anyone looking to supplement their workouts with something cheap, effective and without all the garbage fillers and sugars in most workout supplements on the market today. I have also used this supplement in the past when completing a month long parasite cleanse. I would take two X2 a day and this helped detox ammonia from the die off of the parasites and help me get some sleep. For anyone that’s ever completed a strict parasite cleanse you know what a struggle it is to get yourself to sleep during the cleanse... this def helped! A+ -Multi uses -Great pumps during weight lifting -Increases vasularity -helps sleep -detox ammonia

### ⭐⭐⭐⭐⭐ My go-to Arginine brand
*by C***N on June 20, 2014*

I use this supplement as part of a pre-workout stack. Some believe it can help produce nitric oxide in the body. Some say they can "feel" it, and that may be true. I combine it with other amino acids and supplements. This is a great brand for value and quality. I have purchased lots of NOW brand supplements. I get the Ornithine combo for the added benefits. From my research: "There is currently one study using ornithine paired with arginine that noted improvements in lean mass and power output in weightlifters, but this is an old study that has not been replicated and its practical relevance is uncertain. Finally, the increases in growth hormone seen with ornithine are similar to those seen with arginine. In the end, ornithine looks somewhat promising for reducing ammonia concentrations in the blood and thus enhancing performance of prolonged exercise (45 minutes or more) which is in part due to it being elevated in the blood for a few hours after ingestion despite exercise."
