I am sure you will get different opinions on this, but a few years ago a friend of mine, who was selling glyconutrients and swore they were a miracle for people with CF, sold me a bottle of there best selling glyconutrient powder. It was extremely expensive (over $100 per bottle) and it did nothing. About a month, we got a letter in the mail regarding the company selling the glyconutrients which are being sued and are reimbursing every person who spent any money on any of their products. So, I would be skeptical. They really sell the products, but I have yet to find anyone who can really convince me they are of any value.
