Expert Reviews


What reviewers liked

I have tried many different brands and this is the only brand that works as it should for me. This is my second bottle and won't be my last.
This supplement will help you build muscle mass thanks to L-Arginine, which is an essential amino acid that converts into Nitric Oxide and helps to promote healthy blood circulation.
-
Unlike the other L-arginine supplements listed here, it contains various ingredients formulated to optimize blood flow. The ingredients are 400mg of pure L-arginine, 400mg of AAKG, 400mg of L-citrulline (which is a very potent NO booster), and cayenne pepper (which is a thermogenic).
Also included is a 100% Money back guarantee in case you are unsatisfied with the results.
Improvement in workout performance
With this supplement, you can surely train longer and harder without the feeling of easy fatigability. L-Arginine Extra Strength is highly recommended for athletes, runners, weightlifters, and active and sporty people.
Cayenne pepper boosts metabolism, which in turn enhances blood flow throughout the body's tissues. The same ingredient acts as a natural vasodilator, reverses excessive blood clotting, and reduces body acidity and pain.
With no chemicals, preservatives, artificial ingredients, or fillers, you are getting clean, pure L-arginine that can deliver the results you desire.
The supplement helps relax blood vessels and blood circulation, ensuring that more energy flows to your crucial organs such as the brain, lungs, and heart.

What reviewers didn't like

This product done nothing for me at all! And this is a real review from someone that really works out 4 days a week!
The only downside to this supplement is that it is very expensive. The entire bottle contains just 35 grams of active ingredients. If you are taking a high dosage of L-arginine daily, you’ll go through a bottle quickly.
The Cayenne pepper can be hard on the gastrointestinal tract. The aftertaste is bad and unpleasant.
Only contains 60 capsules. Not suitable for vegetarians
Contains cayenne pepper that may cause heartburn. May cause an upset stomach and frequent bowel movements
​Pricey. Low dosage. Not suited for vegans (contains gelatin)
Complaints about the size of capsule
