## Description

Ornithine is a non-essential amino acid that plays a central role in the urea cycle, functioning along with arginine and citrulline to rid the body of ammonia, a by-product of protein metabolism.* Because ornithine is converted into arginine, it can help to maintain healthy arginine levels in the body.* Ornithine can also be converted into other amino acids, such as citrulline, proline, and glutamate, as well as creatine, an important muscular energy source.* This product is pure, and because no anti-caking agents are used, lumping may occur. This product contains hydrochloride, the acid normally present in the stomach, which acts to stabilize the L-ornithine. Natural color variation may occur in this product.

Review: a miracle for HGH when 25mg taken at bedtime with 500mg ALCAR - Check google scholar you will see the study on this. It really makes me feel so strong the next day. Careful, too much ornithine boosts HGH too much so reduce dose if you are not getting 8hrs sleep. The ALCAR requires choline to work so get some citicoline.
Review: Great If You're on a Parasite Protocol - My nutritionist recommended L-Ornithine to reduce my night-time sweating while taking anti-parasite herbs. I couldn't believe how well it worked! Her brand was super expensive, though, and this product by NOW worked just as well. I took just under a Tbsp to stay comfortable at night.

### ⭐⭐⭐⭐⭐ a miracle for HGH when 25mg taken at bedtime with 500mg ALCAR

### ⭐⭐⭐⭐⭐ Great If You're on a Parasite Protocol
*by J***A on July 16, 2017*

### ⭐⭐⭐⭐⭐ Unlocking Deep Recovery and Metabolic Efficiency with a Versatile Amino Powerhouse
*by P***H on November 24, 2025*

I have been experimenting with amino acid stacks for years to optimize my post-workout recovery and overall sleep architecture, and adding this L-Ornithine powder to my regimen has been a distinct game-changer. My primary motivation for picking this up was the promise of efficient urea detoxification. As someone who consumes a high-protein diet to support muscle growth, I am acutely aware of the metabolic load that places on the body, specifically the buildup of ammonia which can lead to fatigue ("meat sweats," anyone?). Since incorporating this powder, I have noticed a tangible difference in how "clean" I feel after heavy lifting sessions. It acts effectively as metabolic housekeeping, helping to flush out the byproducts of protein breakdown so that my body can focus on rebuilding tissue rather than just fighting off fatigue. The versatility of the powder format is something I genuinely appreciate over capsules. This tub offers immense value because a little goes a very long way, and I have complete control over the dosage. I typically take about half a teaspoon mixed into water or juice. I must admit, L-Ornithine does not have the most pleasant flavor profile on its own—it is not exactly bitter, but it has a distinct, somewhat savory chemical taste that isn't great solo. However, because this NOW Foods formulation is micronized so well, it dissolves almost instantly. I found that mixing it with a tart cherry juice or a flavored electrolyte drink completely masks the taste, making it a non-issue. The texture is fine and doesn't leave that gritty residue at the bottom of the shaker cup that lesser brands often do. Beyond the detox aspect, the most surprising and enjoyable benefit I have experienced is the impact on my sleep quality. I take this about 30 minutes before bed, often stacked with L-Arginine, and the result is a profound sense of relaxation without the drowsiness associated with melatonin or sedatives. It seems to lower my cortisol levels and quiet the physical restlessness that comes from a hard day of training. I wake up feeling genuinely refreshed and ready to attack the gym again, rather than groggy. This specific tub has lasted me months, and given the purity and lack of fillers—no mystery ingredients, just straight amino acid—it is easily one of the most cost-effective staples in my supplement cabinet for maintaining high-level performance and recovery.
