I would buy this product again and again.
I have been using this product and ordering it since the 1980s. Since that time, I haven't missed one day without my DMG. I love the product.

excellent results
I bought this product in the hope that it would create more physical stamina and boost my immune system. I felt a good result on the very first day!! Hoping that long term will show immune boosting in my lab results. Thank you for this terrific product!

Amazing product!
From someone who is knowledgeable about supplements I can't believe this has flown under the radar as long as it has. I heard Dr. Mikovits give a talk about it and it truly is amazing. Can feel the mental focus and energy!

Just OK
[This review was collected as part of a promotion.] I have been using for about two weeks and can not tell a difference. Product is fairly expensive for little results.

Solid product that has worked well for the first week!
[This review was collected as part of a promotion.] Have been using the product for about a week or so taking 1 tablet dailey(usually in the morning before I get my day started). I am not a coffee drinker so its usually takes me a little while to get going but after taking these, I feel like I'm ready to go. One of the most drastic characteristic changes (and maybe it is placebo effect) but I feel laser focused and not trying to find my words(which typically happens). Tablets are easy to chew and, personally, I really enjoy the taste. Has a little sour hint to it with a lemon flavor.

Good product
[This review was collected as part of a promotion.] I've been using this for about a week. I can tell a difference. I feel good and have more energy. I feel more sharp and focused. I'll continue to take it. I'm excited about the results.

I haven't noticed anything different.
[This review was collected as part of a promotion.] It's an easy product to use but I haven't noticed anything different. Of course I just recently started to try it out. I like the info I've read about it so that's a plus.

They are worth it!
[This review was collected as part of a promotion.] I was a bit weary of these but in the end i felt a huge difference in my overall health, i woke up with more energy, not needing coffee and feeling rejuvenated. I didnt get sick not nearly as often & my immune has improved soo much! A bit pricey, but they are worth it!!

It Really Helps!
[This review was collected as part of a promotion.] The GLUCONIC® DMG 500 MG was surprisingly great to use. I wasn't aware of this product before Viewpoints, but I'm glad I know about it now! I didn't expect much because supplements in the past have not worked for me. However, this helped me with my focus and energy. It wasn't a huge difference, but I could definitely feel that it improved my focus and gave me slightly more energy than usual. I can't say much about its claims about helping immunity, but it does help with focus and energy. The only down side that I can think of is that it's quite sour. Other than that, the taste was great. It wasn't too chalky like other chewable tabs are. I would definitely buy these again, and recommend them to others. I think just the benefit of being able to focus better and have more energy is worth it.

Like coffee without the crash
[This review was collected as part of a promotion.] This is the first time I've tried a supplement like this beyond a multi vitamin. I did not know it existed until I tried it. I was not aware of any difference until the 2nd or 3rd day when I noticed I had been getting my steps in (on my watch pedometer) without trying. Instead of being so tired in the afternoon (which is my usual), I felt good. Not the energy like coffee gives, where you're energetic for a time then you crash, but a subtle feeling of just feeling good, and having the energy to do what I needed to do during the day without my usual 3 o'clock crash. This, in turn has helped my sleep issues, because I am not turning to coffee at 3 or 4 pm like I normally do, then having trouble falling asleep due to caffeine. I will absolutely buy this product again. And have already gotten my husband to try it.

A supplement worth having!
[This review was collected as part of a promotion.] I've been using this supplement for a week now. I take 1 chewable tablet in the morning and depending on the day, I will take another mid afternoon. I've noticed an increase in both energy and focus throughout my day, without the headaches you get from caffeinated products. They taste great, easy on the go and I'm excited to continue using to see what other benefits it may provide.

Energy boost
[This review was collected as part of a promotion.] I would continue taking this. Not only boost energy but helps with circulation and immune system!
