Love this product

I haven't tried other Nitric Oxide boosters, but I'm always looking for ways to increase energy and boost performance. The claim is that this can increase blood flow through vasodilation leading to increased energy and improved cardiovascular health. The claims seem a little overblown, but that's typical in the supplement marketThe taste of this is not horrible. It's got a berry flavor, a little too sweet for my taste, but it goes down easy. It's not bad on its own and would probably be fine added to a smoothie or protein shake with a fruity flavor to itI took this every day before workout for a couple weeks to see if I noticed a difference. I did get a slight boost in energy which is always nice. I felt more motivated to get through my workout and noticed that the energy boost didn't immediately taper off like with many other energy supplements. I didn't measure blood pressure so I can't say if it measurably dropped my BP, but I was pleased with the overall effect. However, I don't think it's enough to justify the cost. Most of the ingredients in this are readily available in cheaper alternatives, and I don't think this product provides enough to set it apart from alternatives to warrant the higher cost

Great product used for years started recommend by physician. Good to know can get on Amazon quickly in a pinch but if ordering directly can get a better price.

I have been taking it twice a day for two weeks and will continue to do so for another two to four weeks as recommended. The taste is great with no aftertaste and definitely feeling the boost of energy without any jitters or crashes. Looking forward to lowering my BP and hoping to see some other benefits.

It’s a powder drink that has great taste. Did not enhance my energy or workout performance. Same as most things you buy…states it can do something and does nothing.

This product works well for me. It does lower my blood pressure and it has a very good taste, so no problem to have it as an additional drink during the day. No added sugar is another plus. I have it autoshiped every month and was surprised that it is delivered from a small business. Thank you for bringing such a quality product to the market!

First of all, this product is extremely expensive, so I was expecting this product to be very effective. I ordered it because I was hoping it would be more effective than the other nitric oxide supplements I take before workouts. The website looks...well...to be honest a little like a scam. It gives off 'as seen on TV vibes'. The website points to studies that back up the claims that this particular supplement is much more effective than lab-produced arginine, but I could not find the studies easily, and there were no links on the website.I have gotten through about half of a tub of this supplement. I didn't feel like it had much effect, but that could be because I haven't used it long enough. But at over $70 for 30 servings, I don't think it is worth the high price. I could not find any evidence to substantiate the claims on this product. It doesn't really appear to be a miracle supplement (if it was, I'm sure everybody would be using it). I am sure it does have some positive effects though. If you can afford, I'd say go for it. It tastes pretty good. It tastes sort of like artificial blueberry, and it is quite sweet. I would recommend mixing it with plenty of water. Overall, I'm not super impressed with this supplement. If you can afford it, I think it'd be worth trying. However, I will not be ordering it again.
