NutriKey Complete C-1000 is an easily absorbed, comprehensive vitamin C complex that supports antioxidant status, immune function, promotes healthy skin, and brain function.

Why is this complex better than just taking vitamin C by itself?  Complete C-1000 has additional vitamins and minerals which help buffer the effects ascorbic acid can have on the stomach lining.  Also, with this formulation, the nutrients are more readily available for cell uptake. 

Benefits of supplementing with Complete C-1000 Complex may include:

● Supports healthy oxidative stress and immune function
● Supports cognitive function
● Supports healthy neuronal processes
● Supports collagen synthesis
● Supports healthy cortisol balance

Bye bye inflammation

I was suffering from a shoulder injury (rotator cuff) and needed something to reduce the inflammation (and quick!) I steadily increased dosage until I had diarrhea and then backed down to the recommended dose. The inflammation disappeared within a week. Good stuff!

Quick and free delivery

I have only been taking the product for a few days but was happy to receive it very quickly and I'm excited to feel the results.

Staying Well

This is a wonderful supplement that I find to be a great preventative. I use to have three to five colds per year that were either long term or I never got rid of them. Now...no colds for almost five years....
