[This review was collected as part of a promotion.] A nice add on to my daily routine it's been a good week and noticed more blood flow clearer thinking and not getting dizzy when standing up too fast. Definitely a great item to take on a daily basis.

[This review was collected as part of a promotion.] I received this product in exchange for my honest review from influenster. These seemed fine and easy to take. The individual tablets were flat and oblong. One downside is that you have to take 3 tablets per serving and I can't tell much difference between this and beet root..

[This review was collected as part of a promotion.] All natural ingredients. Not too big. About the size of a quarter and not too thick. Easy to swallow without any taste. I tried this a few times and each time was the same. I got very flushed and felt warm all over. I took it with and without food. I honestly can't say if it works or not but I know I didn't feel good. Sorry, I wanted to love it.

[This review was collected as part of a promotion.] I can't tell yet how these make me feel, but I like that they're compact in a way rather than a capsule because it seems to make them go down way smoother. The filler ingredients could be better but the other stuff in it is good. I hope they work.

[This review was collected as part of a promotion.] Pills are somewhat large and you need to take 3 daily; may be off putting for people who have trouble swallowing large/multiple pills at once. They are solid tablets that won't leak like gel capsules. No aftertaste was noted or weird burps unlike fish oil supplements. My husband and I tried these and didn't notice much of a difference compared to using liquid beet root and eating other foods that increase nitric oxide. No noticeable increase in energy, blood pressure, and no changes in male sexual performance. This may work well for some people if eating nitric oxide boosting foods and/or swallowing pills is preferred to a liquid beet supplement.

[This review was collected as part of a promotion.] I took these for two weeks and stomach issues started after the second day. After two weeks I stopped and after one week the stomach distress has gone away. Although the pills are easy enough to take I will not be taking them again.

[This review was collected as part of a promotion.] Doctor's Preferred Nitric Oxide Advantage is an easy-to-take supplement that supports overall cardiovascular health and circulation. The tablets have a pleasant taste and dissolve quickly. After consistent use, I noticed improved energy levels and endurance throughout the day. It's a convenient option for anyone looking to support healthy blood flow and heart health as part of their wellness routine.

[This review was collected as part of a promotion.] My husband has been trying these to help with blood flow. It's too early to tell if it's helping. They are easy to swallow, and no bad taste, even after a few hours. We are waiting results after he takes them for awhile.

[This review was collected as part of a promotion.] I've been taking this supplement for a few weeks now and honestly, I can't tell too much of a difference between before and now. There doesn't seem to be any adverse side effects for me. No smell or odor from the physical pill itself. Pill size is easy to swallow. Overall, it might need a few more weeks for me to notice any difference.

[This review was collected as part of a promotion.] Not sure if these are doing anything yet, since I haven't been taking them that long, but I will continue to take them. The ingredients are very straightforward and seem pretty natural. The instructions are easy to follow, just take three a day. The bottle was easy to open and the pills are easy to swallow. No weird odor or flavor.
