Rachel from Women's Health News blog has a good post about how to evaluate health/medical websites. Being relatively new to the dietary supplement industry, I have been amazed at the amount of "secrets" in the industry. From "doctors" with fake degrees to guys selling hand-stuffed bottles out of their apartment, it is becoming increasingly important to research the company/sponsor/etc. of the website that you buy products from.
And that's why at Jigsaw Health, we've taken the time to show pictures of our office and warehouse (along with sourcing all of our articles and backing up all of our products with links to scientific research!) to give consumers confidence in what they are purchasing.
