Supplement to promote healthy vasodilation and blood pressure while enhancing cognitive function.


Supplement to promote healthy vasodilation and blood pressure while enhancing cognitive function.

Recent Nobel Prize winning research has led to a deeper understanding of the important role played by the simple molecule nitric oxide, known to influence many of our most basic health processes, including the cognitive learning and healthy blood vessel tone. In our bodies nitric oxide functions as a signaling molecule which may:

  • Influence cognitive function,
  • Help maintain blood pressure levels that are already normal.
  • Promote healthy immune and nervous system response.

Dr. Peter D'Adamo, author of Eat Right 4 Your Type formulated Nitricycle by blending together botanicals with the amino acid L-Arginine which is an essential precursor of nitric oxide. This unique blend helps to maintain healthy blood vessel tone thus making it popular for athletes and exercise enthusiasts. There is some evidence blood types B and AB may benefit more from Nitricycle although it is good for all types.

Nitricycle is produced in the USA and is GMP (Good Manufacturing Practices) quality assured and certified product as outlined by the Natural Products Association and is suitable for all blood types.

  • Nitricycle

    Posted by T. Dan Tolleson on Apr 28th, 2020

    Nitricycle helps "promote healthy vasodilation." I knew that my circulatory system was going downhill. I couldn't run very much anymore because of foot pain caused by corns. Then I discovered that corns are caused at least as much by declining circulation as by poorly fitting shoes. So I tried Nitricycle. After 2 bottles (2 months), I've noticed an increased springiness in my feet. I'm starting to run short distances. The corns on the one problematic foot are going away, even though I'm wearing the same shoes that I thought had given me corns in the first place because of a poor fit. This could be my imagination, but the light-greenish tinge of the skin on my calves is slowly changing to a slightly more orange tint. Thank you, Dr. D !!!

    I can't say enough about this. I feel calmer and am able to focus more intensely. The brain fog i used to deal with on a daily basis is gone! Recall is much improved. Thank you!
