Advanced Bionutritionals are not disclosing contraindications and side effects of one of their product, Advanced Sleep Formula. I took this product and felt sick. I checked all ingredients in the Internet and I found out that one of them, 5-HTP (5-hydroxytryptophan), has many typical side effects and contraindications.
(You can check at http://www.ehow.com/about_5444904_hydroxytryptophan-side-effects, http://www.advance-health.com/5htp.html, and many others, just google 5-HTP side effects and/or counter-indications)
The company is registered at the Better Business Bureau. I made a complaint asking for the side effects to be published in their product description but they refused. Better Business Bureau closed the complaint deciding that Advanced Bionutritional made an effort to solve the dispute (!?!) but the customer was not satisfied.
As also reported on Ripoffreport site, Better Business Bureau (in my opinion 'Bad Business Bureau) is accused by many people and companies of being corrupted as they give high ratings to company that pay them, as supported by ABC news. [continued below]....
Advanced Bionutritionals fully refunded me. (Though I asked them to pay also the return shipping costs, which they didn't)
Advanced Bionutritional have a history of false claims in their product description: in fact, in 2004 Advanced Bionutritionals stopped advertising one of their product that was reported to the Federal Trade Commission for unsubstantiated claims (File No. 042 3123).
The product description of their Advanced Sleep Formula is misleading indeed, as it is claimed to be a very safe product also compared to other natural supplements like Valerian and Melatonin.
