Do chewable gummy multivitamins get properly absorbed as much as regular USP verified tablet multivitamins?

"Novirin and Gene- Eden- VIR are natural antiviral supplements backed by clinical studies followed by FDA guidelines"- Is that true? Can I use them??

Garbage: pure hooey. Because companies that manufacture garbage like this have such strong lobbyists, they can put whatever they wish on the label--so long as they print that they do not claim the junk will treat any disease. I have many patients with severe immune problems and if this junk worked I would be extraordinarily happy. Treat hepatitis C? And all those others? Bull. ...Read more

Does curvier plus vitamins are safe and approved by fda ?

Does curvier plus vitamins are safe and  approved by fda ?

Probably safe but...: I can't know for sure as I was unable to find details of what they contain. I found this list of ingredients: http://tinyurl.com/z9av57t It looks like they contain herbs rather than vitamins. These herbs have a long history of medicinal use and are generally safe, but not all herbs are appropriate for everyone so side effects are possible. The FDA does not "approve" supplements but regulates them. ...Read more

Is D. Mannose supplement for urinary health and UTI prevention safe/clinically proven effective?

Depends . . .: If you ask enough people, eventually you'll get the answer you want to hear. With that said, there's a big leap to take from theory to animal studies to humans. So while many new drugs are expensive, it takes a lot of research to get them approved. Check out http://www.med.nyu.edu/content?ChunkIID=225997 which points this out. Then check out http://www.ncbi.nlm.nih.gov/pubmed/23633128. Maybe!!!! ...Read more
