Yo, please don't fear the flushing. Please don't fear the headache. Start start out with a quarter instead of a half or or even a hole start out slow and do it a couple times a day. Your body has been suffering with no adequate blood flow. When your body gets a hold of the ingredients in this product, mind you look at the ingredients they are all natural. And it opens up your capillaries and some smaller blood veins that have been closed for a long time you're going to feel a little different. So what you do as you start out slow so your body can get used to the difference is slowly. I did a half the week. With some of the days doing a half again after lunch. And a week after starting, I was driving at night, which is not something that I usually can handle very well, but the lights were actually not as halo as usual. It was actually very noticeable for me. So the capillaries in small blood veins in my eyes are definitely reaching benefits. Yes I got one little pain in my chest, but it was just blood flow then I got a headache once it was just blood flow. If you do your research, you'll see this is not dangerous. It's actually healthy. It's actually healthy but just go slow. It's not a race or Health is not a race. go slow start out slow. You will be so happy that you did. Read more

My doctor recommended this for me as part of my overall health maintenance generally and for heart health/blood circulation specifically. It is now part of my daily routine. I like the mild “sweet tart” flavor and trust it is providing an unseen benefit. It’s on a monthly auto ship for me and I plan to keep using it. Read more

⭐️⭐️⭐️⭐️⭐️ 5.0 out of 5 stars Noticeable Energy & Better Circulation in Just Weeks I’ve been taking Neo40 for about three weeks now, and I can honestly say I’m impressed. The dissolvable tablets have a pleasant fruity flavor — no chalky or bitter aftertaste like some supplements. I take one in the morning and within a couple of hours I feel more awake, focused, and generally more “alive.” What’s really noticeable is the improvement in circulation. My hands and feet used to feel cold a lot, but that’s almost completely gone. My blood pressure readings have also been a little more stable, which is a big win for me. The tablets dissolve quickly under the tongue, which makes it super convenient — no water needed. The price is on the higher side, but if you’re looking for a natural boost to nitric oxide and overall cardiovascular support, it’s worth it. Pros: Tastes surprisingly good Easy to take anywhere, anytime Noticeable boost in circulation & energy May help stabilize blood pressure Cons: A bit pricey for a monthly supply Bottom line: If you’re serious about heart health and want something that actually delivers, Neo40 is worth trying.

This is jet fuel for your vascular system. It was so good, I had to throttle back because it lowered my blood pressure just a bit too much. It tastes great, and has a normal losenge texture. It functions like a pharmaceutical grade product, with over the counter accessibility. Helps me sleep also Read more

I am one of the many aging people whose normal endogenous production of nitric oxide (NO) has shut down. I am experiencing the usual symptoms from lack of NO. I have been trying Neo40, 2/day divided doses as advised. I go by test results twice a day with NO test strips (HumanN is my favorite). Neo40 does provide a bump in NO level but not very much. Typically I go from Depleted to Low but definitely not Optimal. The Neo40 effect also seems to disappear fairly rapidly (less than 12 hours). I get dramatic results (Optimal) from canned spinach or beet vegetables so my system is capable (saliva bacteria are doing their job etc.). Veggie effects can extend to 24 hours. Veggies are difficult to do consistently once or twice a day (and, oxalates) hence the need for a product like Neo40. I am aware of positive literature for Neo40 and a leading NO scientist favorable comments in the book Integrative Cardiovascular Medicine. I don't know how to reconcile this information with the 'meh' effect I am seeing. I think sellers should provide a summary of the Neo40 effect and timeline they should be seeing to help consumers know what to expect and whether Neo40 is succeeding or failing for them. This is missing information. I think all consumers should test their personal response with NO test strips (and watch out for other sources of dietary nitrate that can confuse results). Otherwise consumer response to Neo40 is just a subjective guess. Thank you. Read more

I noticed a real difference after only 3 days. I'm sold. Easy to take and I can feel the results. At the risk of having a run on Neo40, I am stunned at how good I feel--literally decades younger. I consider this a real game changer for my health and I'll be a customer for life. A doctor recommended this to me and I am so glad he did. Read more
