OxySpark, Nitric Oxide Booster Dietary Supplement, Award-Winning Ingredients, Clinically Proven Ingredients. Increased Blood Flow, Cell Repair, and Energy. Senior Supplement Beet Root. 1 Pack

Tastes great. I think Human Beets packs more punch, but Human Beets is a challenge to drink for me. I mix 1/2 of this with the scoop of Human Beets and add some crystalized lemon and voila- very drinkable.

This stuff is great. I have more energy, more stamina, and clearer thoughts. I feel muscle forming after very little effort. My male machinery downstairs is working better than it has in years. And it tastes great. It takes zero effort to get it down in the morning. I have not noticed any side effects so I see no reason not to take this for years to come.

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.

I’ve tried a lot of supplements over the years, so I don’t usually expect much; but this one really surprised me. I started noticing a difference within just a couple of days, especially with my energy. Now that I’m about two weeks in, I can honestly say I feel a big improvement. My energy is more consistent, my mind feels clearer, and my focus is noticeably better. One of the biggest things for me though is motivation—I’ve had way more drive to actually get things done instead of putting them off. It doesn’t feel like a spike or anything artificial, just a steady boost that lasts throughout the day. A friend recommended it to me, and I’m really glad they did. This is one I’ll definitely be sticking with long term. Totally worth it.

I recently went on a lengthy business and vacation trip. Didn't realize until too late that I forgot to pack my OxySpark. By the end of the trip I was tired, and just not functioning at my normal pace. As soon as I returned home I immediately started back on my daily routine of OxySpark. Within two days I could feel the difference. My energy levels were better, I was sleeping better and just felt better. Will never travel without it again! This product is reasonably priced for the results that it gives!
