Neo40® Professional is a clinically researched, patented technology in the form of a quickly dissolvable tablet. It is the first and only system to safely generate an independent source of physiological nitric oxide (NO) for systemic restoration. 

  • Promotes increased circulation throughout the body
  • Supports cardiovascular and heart health
  • Supports healthy blood pressure levels and healthy arterial function (vasodilation)
  • Improved ability to get oxygen and nutrients to the body’s cells, boosting healing and immune functions
  • Improved mental acuity
  • Supports decrease in development of cardiovascular disease (CVD)
  • Promotes improved regulation of insulin levels and increased kidney function

Nitric oxide controls many of the body’s functions, especially circulation and the ability to get oxygen and nutrients to our cells. Nitric oxide deficiency plays a significant role in the development of diabetes, obesity, hypertension, and elevated blood fats (metabolic syndrome).

Neo40® Professional is designed to support the body in nitric oxide production. Nitric Oxide controls many of the body’s functions including circulation and the ability to get oxygen to each cell which also plays a significant role for your immune system. 

Nitric Oxide production decreases with age and is rapidly decreased after age 40. Neo40® Professional is designed to work with your body and help support nitric oxide production.

It Works!

I've been taking NEO40 for about 4 weeks now and I've already experienced increased energy, as well as increased athletic performance on my bike workouts - as it allows my blood and blood oxygen to circulate more efficiently. Highly recommended!

I did like the item... I had no problems with taking it... and it did seem to maintain my blood oxygen levels. My only concern is that it is quite expensive for my level of income. Thanks, Tom Gerdes

Definitely a great product

I have diligently used what I perceived to be a high level of vitamin and health products, however, I didn't realize what a high level was until using the Restore shake. My office was exposed to Covid and three of us were positive and became sick. Of the three, I am the oldest by many years. I immediately began using Restore, Neo40 and Lugol's Iodine Plus. I recovered the quickest and had the least severe symptoms. These products have become an important part of my pursuit of a healthy lifestyle and are very supportive of my workout level and schedule. I would highly recommend them to anyone!

I’ve used Neo40 for several years, the same time I began using several other Tennant products. I’m healthy and generally feel very good. Which product did that? I trust Dr Tennant to know and formulate what I need so I’ll do my part and be faithful to myself and follow his directions.

Gave It My Best

I used the neo40 tablets for 16 days straight. I followed the directions and made sure I hydrated before and after taking it. I found the taste very pleasant and the tablets dissolved fairly quickly, however my mouth eventually became raw. I tried chewing the tablets, but I ended up with severe heartburn, so I am not able to take this product! I was very disappointed as I was looking for a natural product to keep my blood pressure down.
