Great addition to my daily routine

[This review was collected as part of a promotion.] I have been taking Nitric Oxide Advantage consistently and so far I have been pleasantly surprised. The packaging is clean and sturdy and the bottle seals well, so I don’t have to worry about the product spilling if I toss it in my bag. The instructions are pretty straightforward and easy to follow, which I always appreciate since I take several supplements already. The capsules are easy to swallow and and there isn’t much of an after taste. After using regularly I have noticed a little more energy throughout the day, and my blood pressure has been running lower then it was so that’s been a welcome bonus. I know everyone’s experience will be different but it’s been a positive addition to my daily routine. As far as maintenance costs go, I think it’s reasonable for a supplement I use everyday, especially if I continue seeing the same benefits. Overall, I am happy with it and plan to keep it in my supplement routine.

Great energy level and heart healthy

[This review was collected as part of a promotion.] For the duration of me taking this product I had constant energy but not jittery or shaky it was a good dosage of 3 a day and the ingredients were healthy and the pill had a smooth texture. I will be buying these again.
