Do chewable gummy multivitamins get properly absorbed as much as regular USP verified tablet multivitamins?
Probably: Not all gummy vitamins are created equal and some are undoubtedly better than others, but they should contain high quality vitamins in a different base than tablets. The fact that they are chewable may increase their absorbability, but i don't know any objective research on their absorption so this is all just an educated guess. ...Read more
"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

Is the nutritional supplement Ultra Potent-C®, made by Metagenics, bioequivalent to vitamin C from food sources?
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

No: The federal drug administration (fda) does not test drugs or supplements. The fda evaluates research studies on medications to make sure they are effective and safe. Supplements are regulated under a separate law and don't have to be shown to be effective, but the manufacturers can't make claims about how they affect health. ...Read moreSee 1 more doctor answer

Policosanol: Companies selling policosanol claim it can help lower cholesterol. It's a product made from sugar cane. Many of the positive studies come from cuba, which grows the cane used to make the product. Studies outside cuba (south africa, germany, canada, etc) didn't show effectiveness. So, it seems more needs to be learned or shown about this one. ...Read more
Yes, can take both: Vitamin e and omega-3 fats like dha and epa are ok to take together. There is some evidence that antioxidants like vitamin E may improve sperm quality (less dna damage) but the studies are small and it's far from proven. There is no good evidence that either supplement improves female fertility. ...Read moreSee 1 more doctor answer
Mostly: There is no regulation or oversight in this area since the supplement lobby got congress to pass a bill forbidding the fda to even look at these products. Most however are very safe as the manufacturers are sensitive to toxicity and hazards. However few have ever been tested for potency or effectiveness and most fail such testing. Don't waste your money. ...Read more

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 moreSee 1 more doctor answer
