Increased stamina

[This review was collected as part of a promotion.] Seems to work well. As a daily supplement, does seem to increase blood flow. Have noticed increased muscle pump and stamina with exercise since using it. Can't say it's anything remarkable or drastic, but is noticeable.

Easy to take, well-packaged, and a convenient supplement for daily wellness support.

The capsules are easy to take, and the bottle is clearly labeled with dosage instructions. The packaging feels secure and keeps the product fresh. After consistent use, I noticed improved energy and overall wellness. I also appreciate that the product is convenient to store and fits easily into my daily routine. Overall, it is a quality supplement that is simple to use and provides good value.

Easy to take

[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.

I like these

[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..

Perfect for heart health in adults

[This review was collected as part of a promotion.] These supplements really don't have a smell to them which is surprising. They come in a standard bottle easy for storage. You take 3 pills a day with or without food. The consistency of this med seems to help heart, energy, and circulation.

Takes time for effects to kick in

[This review was collected as part of a promotion.] Nitric oxide advantage gives a gentle energy boost and subtle muscle pump. Decent circulation support that takes time. Taste not so great and neither is the smell but not many smell to great. Not really into taking three a day a little overwhelming.

Provide energy fast

[This review was collected as part of a promotion.] Really good supplement. There are 90 tablets in the bottle so 3 per intake would leave you with a month worth of supply. The tablets are not too big as you can see it in my picture, and it was easy enough to swallow them. There is no strong smell, which I liked. But the most important thing is they really provide you energy, and there were no side effects for me.

Good for cardiovascular health

[This review was collected as part of a promotion.] This is a recommended dietary supplement. It is easily digestible. I have not had any stomach problems taking it. I'm hoping to boost circulation and achieve better cardiovascular health. There is no aftertaste. I would say this overall will be a good supplement to add to my daily vitamins.
