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.

definitely a supplement I plan to continue taking 🙌🏼

[This review was collected as part of a promotion.] great product, overall happy with the increased notice of energy without the crash. the recommended dosage is 3 tablets once daily which is reasonable but I think even 2 a day would still work for me. they were easily digestible and taste wasn’t bad either 😊

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.

Mental boost & increased blood flow

[This review was collected as part of a promotion.] I've been using this vitamin for a few weeks and have to say I really like it. It actually does give me a subtle mental boost and helps keep me focused. I like to take it about an hour or two before I work out to increase blood flow. This is something I will likely continue to take as I enjoy the benefits.

Take care of your heart health

[This review was collected as part of a promotion.] I’m choosing to take better care of my health and with that being said, I am taking this to take care of my heart. I take 3 daily with food and sometimes without. Just depends on the day. But goes down easy.

Easy to digest. Improved Energy

[This review was collected as part of a promotion.] After only a few short weeks of taking the Nitric Oxide Advantage, I we feel an increase in my energy. There is little to no odor and the pills have a shape that makes them easy to digest. There is no aftertaste whatsoever. You take 3 pills daily and the bottle is easy to open and store.

Seems good

[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.

It’s okay

[This review was collected as part of a promotion.] I had mixed results with the Doctors Preferred Nitric Oxide Advantage It was easy to take, but I didnt notice a significant difference in energy or circulation compared with what I was expecting . It may work better for some people, but for me the effects were pretty mild . Overall, Its an okay supplement, but I probably wouldnt purchase it again
