Healthy Origins L-Arginine Powder 5,000 mg per Serving, 10.6 oz (300g) - American-Made USP Grade Amino Acid, Nitric Oxide Precursor Supports Heart Health, Sports Recovery & Performance - 60 Servings

Excellent quality

At my last dentist appoint, I discussed with her my sensitivity issue. She told me to use a toothpaste containing arginine. I now make my own using this Arginine product and NOW calcium carbonate powder. I also use a toothpaste containing nano-hydroxyapatite. The n-HA forms a matrix on your teeth that heals up tubules….lessening tooth sensitivity. This L-Arginine product is a very fine pwder that has zero taste. I’m constantly reading reviews on L-Arginine of people that people can barely tolerate the taste. To me, this brand has zero taste.

Seems good so far. I’ve noticed increased energy and strength. I can do 50-55 push ups straight now. Couldn’t before. I like that there are no extra ingredients. I recommend this product

I contacted the company to verify where the raw product is sourced from. They responded that L-Arginine and L-Citrulline raw material is processed in the United States. "The starting raw material for L-Citrulline and L-Arginine fermentation is glucose from corn syrup. The corn is harvested in the U.S.A." Most source from overseas (China). This shows their dedication to quality and consumer trust. The price is also similar to competitors making this, in my opinion, a better value.

L-arginine is an amino acid that has blood vessel dilation properties and can be used to help lower blood pressure. It can also lower blood sugar and improve athletic performance for better workouts. This particular supplement comes in a powdered form that is supposed to be mix into water or juice. The serving size is measured by an included scoop, providing 60 servings. The product is a very fine white powder that mixes easily in water. The label warns that the powder is very bitter, and it was right. I mixed it into a cup of water and drank it straight. It tasted like bitter fish juice, quite unpleasant. A squeeze of lime and teaspoon of sugar made it more palatable. I have taken L-arginine before and noticed positive effects on my blood pressure and maybe a slightly easier workout. This particular supplement is made in a certified GPM facility and third party lab tested to insure quality. A COA is not provided as proof of content however. Overall, I like this supplement and the health benefits that it offers. The taste is a problem, but that can be overcome if added to a smoothie or something else that is pleasant tasting.

Is it just me or tastes like rotten egg or something putrid?

6.25.23~ Healthy Origins Vitamin C is my GoTo. It's a small tub, full with product not space. It works with a small scoop & tastes good. So not surprised the L-Arginine is packaged the same. A tub no bigger than a small jar of jelly & no wasted space. It's also the 1st time L-Arginine hasn't bothered my belly. Tried powder, liquid in a drink & capsules. Every time my Plant based stomach either rumbles. Or the back of me does. You know what I mean & I'm not gonna say it. The best part of Healthy Origins version besides common sense is, It Works. My ol' tired muscles are just done lately. I've been working harder than Santa on Dec 24th (or the Ups driver) After a week of daily use, that knot between my shoulders is manageable without Biofreeze. Maybe it's placebo bc of my belief in this company but I'm gonna keep believing.

I take this L-Arginine powder in the morning with my nitric oxide supplement. I mix a scoop full in my orange juice and it dissolves so easily. There are no clumps or residue left behind like some of my other supplement powders. Some key features and why I chose this product over some others: 1. Non-Gmo 2. Gluten-free 3. Bpa free 4. aids in muscle support 5. 3rd party tested 6. No artificial sweeteners, magnesium stearate, titanium dioxide, or preservatives. It's especially difficult nowadays to find supplements with no magnesium stearate and titanium dioxide. I'm very satisfied with the ingredients of this product and definitely recommend especially if you like to exercise like me.
