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.

Excited to try

[This review was collected as part of a promotion.] I’m so excited to be giving this supplement a try in my regular vitamin regimen! I recently found out that I have poor blood flow and I am really hoping to see some results with continued use. I wish the serving size was less than 3 per day, however the tablets are not too large, and do not have any unpleasant taste or smell.

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..

Better than the other's I've tried!!

[This review was collected as part of a promotion.] This is a good nitric oxide supplement!! The bottle has 90 tablets, the daily dose is 3 so its 1 months supply. It looks more like a vitamin, not in capsule form so it is easier to swallow. I've been taking it about 2 1/2 weeks now, and i have to say I have more energy and an overall feeling of well-being. I haven't noticed any side effects from this supplement.

"A+ for this Supplement!"

[This review was collected as part of a promotion.] These "Nitric Oxide Advantage Dietary Supplement Tablets" make me feel great and energetic! These tablets are easy to swallow, and I have "peace of mind" knowing that these are good for my health, specifically for my heart, circulation, and energy. I really like how these tablets are "4X better than beet root," so I would absolutely recommend these. Thank you to Influenster and Doctor's Preferred for this Product!
