The best vitamin available!

I have severe insulin resistance, PCOS, IBS, severe food allergies, and a host of other health concerns. When I finally got to a doctor who could help me, my system was very depleted of minerals and vitamins and I felt like the walking dead. The first thing my doctor did was put me on a multivitamin but it upset my stomach. We went through 4 different brands but still they upset my stomach. My doctor told me to just take them anyway. I got sicker and sicker with severe stomach trouble and finally out of desperation, I went to another doctor who explained that this brand of vitamin is formulated differently so that it can be recognized by the body and assimilated into the body. I thought that this brand would be no different than the ones before but I agreed to try once more! Well, from the start, this brand was different. I actually felt BETTER taking these vitamins. And I have had no stomach upsets, or problems taking this brand. I have been taking it for over a year now and I have been feeling much better.<br /><br />Others have mentioned that this is a very expensive vitamin. But, take it from my personal experience, I tried vitamins that cost even more than this brand and I experienced major stomach upset and trouble and I couldn't see the results that I see taking these vitamins. If you have a sensitive stomach, you may definitely want to give these a try. They are definitely worth the price!

GREAT FOR HELP WITH MANAGING BLOOD GLUCOSE!!!

As the first reviewer said, this vitamin supplement isn't cheap, but it has definitely helped me to stabilize my blood glucose levels, weight and improve my stress tolerance (there is a good amount of vitamin B12 and Chromium in this formulation)! In the past, I would switch to a less expensive supplement and immediately noticed no change in lab work or mood then returned to Metabolic Synergy. It's a product I willingly set money aside for each month since I want to keep my family history of diabetes out of my own life!!!

regulated blood sugar in 24 hours. I had low ...

regulated blood sugar in 24 hours. I had low and high as I am recovering from severe adrenal fatugue-high cortisol and hypopituatary and hypothyroid..this formula should be one of those supplements thats in every household across america..I think it would help all the blood sugar issues, obesity issues and fatigue epidemics. Hats off to the two doctors that formulated this!

Lowered my fasting glucose from 101 to 72

My awesome Nutritional Doctor put me on this, I feel energetic and dropped my glucose by 30 points. I also used Silvercilin from Designs for health, awesome anti microbial that kills candida in the digestive track. Now am doing probiotic to maintain healthy gut flora. Metabolic synergy is the right choice.

Formulation Change - New Version is Terrible

I ordered this product for the first time in 2018 and absolutely loved the effects of the product. However since then they have significantly changed the formula. I ordered a new bottle about a week ago and started taking the new bottle. After about 2 or 3 days I broke out in hives all over my body in an allergic reaction to one of the new synthetic fillers they added to the new version. I compared the old bottle to the new bottle to see the significant change in product. I’m so upset, I really wanted to continue to use this product but it’s not the same. I’m not even sure if the new formulation works because I wasn’t able to use it long enough to find out. I wish I could give this new version zero stars.

Sleepless nights...

So I read some articles and researched the reviews for this product; I normally don’t review anything I buy but I believe this is something I thought would be helpful. I have been sleepless for months now, due to a combination of things, like stress, and would be awake almost all night. My dr gave me three months to loose pregnancy weight before retesting me for diabetes since my last tests were prediabetes, so I wanted to take vitamins or something that would help me also because I have a history of a dysfunctional thyroid, to sleep better, and better control my sugars. I got the product Monday and I started right away with taking it, only half of the recommended serving, and with this and gluco supreme herbal vitamin, I have been able to sleep! That’s the first improvement, I have been dieting and watching my sugar intake and drinking nothing but water to help with my diabetes and my sugars were still very high 180/190/200, not getting better at all, and three days later I actually saw the lowest number I had seen over three months of taking my sugars 168!! That’s pretty low, of course it’s probably because of the sleep I finally had three days in a row!! I really am excited to see what happens after using this for a longer period of time! I’ll be sure to comment Again in June when I retake my tests!
