This product will change your hormones

Posted by Reviewer1446534 on Jun 11, 2014

unfortunatly this product contains Enteric capsules which are toxic to the body because it changes the testosterone into estrogen and vise versa. please look up "What Are Phthalates & What Are They In?" - If i knew this i wouldn't have done this i wouldn't have taken practically the whole bottle

Great product..BUT !..its coated with a banned plastic !

Posted by Reviewer2494531 on Sep 21, 2012

Ive only been using this for a short time and so has my 71 YO mother. We have both felt better only after 2-3 weeks. The problem is,we wont be using this brand again because of the enteric coating which is made of a banned plastic ! Can you believe that. ALL of doctors best enteric coatings are made of "hpmcp" which was banned from childrens toys in 2003. What retarded person in DrBest then thought it would be OK to use it to put it into our body. Idiots. So here is their email. PLEASE tell them you are not happy with "hpmcp" and maybe they will change the enteric coating to high dencity cellulose which is NOT harmfull. info@drbvitamins.com Its outrageous that this coating is used in ALL their products. Plastic has serious side effects on hormones. WE DO NOT WANT THIS ON OUR SUPPLEMENTS ! ------------------> ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ * 8-12-2013 - RESPONSE FROM: Doctor's Best: We regret the miscommunication to iHerb because Doctor’s Best removed the usage of Hydroxy propyl Methyl cellulose- Phthalate (“hpmcp”) in Q4 2012. All Doctor’s Best Serrapeptase products are currently manufactured with a specially designed Serrateric™ system which encapsulates the Serrapeptase ingredient itself; not the capsule. Serrateric™ is a non-GMO natural coating-free acid protection system. Serrateric™ is a combination of approved food additives (self-affirmed GRAS) that work to provide gastric protection for pH sensitive enzymes without the need for additional coating. The Serrateric™ system dissolves by coming in contact with bile salts found only in the small intestine assuring bio-absorption of the Serrapeptase active ingredient past the stomach pH environment. Doctor’s Best does not believe the products provided previously were unsafe but we do recognize advances in science and technology afford us the ability to consistently improve our products and formulations. We sincerely believe we have partnered with our manufacturer to develop the safest and most effective Serrapeptase product on the market.

have been taking stronger dose and now downgraded to this lighter does, hard to say if it is doing anything. my throat and inflamed phlegmy bits did not seem to get better thoughout this last bout of flu - and phlegm flooded asthmatic attacks seem as bad as w/o serrapeptase. I DO SO want it to be the miracle cure it's been touted as being

It's hard to find any literature about the negative side effects of Serrapeptase. If you search the internet it looks like a miracle enzym. And it is for many people, but not for me and not for my friend. First I had some fatigue and head ache, this can be normal for the first days. After a week the fatigue was gone and I didn't notice any positive effects. A week later I started to have MORE PAIN in almost ALL MY JOINTS and much acid in my muscles. When I checked with my friend she had the same reaction, so I was sure it was because of the Serrapeptase. But... maybe we just had to get through this and then it would be better, so we tried another week. Then my friend got pneumonia. She was getting sicker every day. And I didn't feel good either. I searched the internet for negative side effects, but couldn't find any in the first place. After a couple of hours I finally found something and it became clear that our pain en her pneumonia was caused by the Serrapeptase. We both suffer from FM (Fibromyalgia) and MPS (Myofascial pain syndrome) and my guess is that the latter in combination with Serrapeptase can cause more pain, inflammation and in my friends case pneumonia. It may help for FM, but be aware that most people with FM also have MPS and my reaction to Serrapeptase was more pain, inflammation in the muscles and many more trigger points! So, if you have FM and want to try it, pay close attention to how you feel!
