Doctor's Best D-Ribose with Bioenergy Ribose, Non-GMO, Vegan, Gluten Free, Energy Enhancement, 250g, 8.8 Ounce (Pack of 1)

I started using this years ago after i saw Dr. Oz on Good Morning America talking about natural remedies to help with fibromyalgia (which I suffer from severely) He specifically named the Doctor's Best brand, and in powder form, as your body absorbs it better and much faster than in a pill form. I add it to my coffee in the morning and sometime mid-day to keep my energy levels up in something like tea, crystal light, whatever. I was absolutely shocked when I first started using it! My energy levels were increased more than I can possibly explain! The energy is so different from caffeine, you never get a crash, it just gives you a natural energy boost that's unlike anything I've tried (and I've tried EVERYTHING) The taste is great, not strong at all, but it's a little sweet. Almost a slight butterscotch or vanilla taste, not chemically at all. At first I had to work my way up to the recommended two scoops a day (the scoops are tiny) because it actually gave me too much energy! It not only helps with the constant fatigue from fibromyalgia, it also helps my muscles ache a lot less. I used it for a couple of years, ran out and just kind of forgot to order it again. You stop noticing how much it does for you after a while. Within a week all of my fatigue and muscle aches were at it's highest. I had no idea it was doing that much for me until I stopped using it! I Immediately ordered more, and I will never let myself run out again! I can't attest how it would work for other uses (I believe it's used with a lot of weight trainers/ body builders), but if you have fibro you MUST have this in your daily diet. It's by far the best product I've tried over the past 10 years to try to help ease the symptoms of fibromyalgia. I feel like it's given me back a part of me that fibro took away. I can't say enough about it. Thank you Doctor's Best for literally changing my life (and Dr. Oz for recommending it...I never would have found it otherwise!)

I've ordered this several times for energy. While D-Ribose doesn't work to boost energy for everyone, it is cheap enough that it is definitely worth a try. It's great added to electrolyte drinks while working out or in the morning for an extra boost of energy. Highly recommend.

Don’t hesitate, get this now! I have CFS and idiopathic hypersomnia so I’ve tried it all. I have not had to take my stimulant medication in 3 weeks. This is absolutely unheard of for me. I am shocked in the best way possible. I put a scoop in my morning coffee and then again in my afternoon coffee or tea. It doesn’t change the taste of either and dissolves right away. There is no jitteriness or jolt of energy, it just lifts the heavy dark cloud off of me. I did try Bill supplements brand since I take their taurine and it is cheaper, however, it didn’t seem to work as well as this brand for some reason. I will be a customer for life, I’m finally feeling like a normal person!

I have Fibromyagia Syndrome/Chronic Fatigue Syndrome and for the past year have been exhausted more than usual. I'm in my early 50's and think it may have something to do with going thru menopause. I saw an episode of Dr Oz and he talked about using D-Ribose for FMS/CFS, so I thought I'd give it a try. I read up online a bit first before I placed my order to see which type I should purchase so I wouldn't waste my money. The research stated that they used a brand called Corvalen, but it was really expensive, so I read the reviews for Doctor's Best and decided to take a chance on this one. The first couple of days, I noticed a little more energy, but the next days and the next week, WOW. It really make me think a lot more clearly and I was functioning a lot better in my thinking and response time when I was gaming (I'm a die-hard COD player. Yeah, I'm over 50 and I'm a gamer, laugh all you want ...but it takes my mind off of my pain and helps to relieve stress). My scores went up significantly. I was also able to start my Yoga again, which I haven't had the energy to do for months now and I wasn't tired afterwards, I actually felt better and had more energy. These past 2 days now though, it doesn't seem to be working as well. I'm still taking the same dosage (5 grams, 3 x a day added to a small amount of grape juice or yogurt), the same way I have always taken it. The mental clarity and response time seems to have gone back to the way it was before even though I've not changed anything. Wondering if it could be related either to my cycle or maybe my FMS/CFS flaring up. If anyone knows why this happens, please let me know. I've been tempted to use more than suggested, as I have heard some people say they do (only side effect seems to be the 'jitters'), but it's too expensive to go thru that much. It does seem to work (most of the time), but it's really expensive and people who are ill and need this (such as myself) are probably already strapped by all the meds and equipment they are already paying for. It would be nice if these supplements that are suggested to us for better health would come at an affordable price since they are advertised as something that we need to function 'normally'. Also, if this is a 'maintenance' supplement, it would be nice to be able to buy it in a larger container at a lower cost like a lot of other companies sell their product. This container doesn't even contain enough for a months supply and it should (it contains 50 scoops, suggested at 2 scoops a day = 25 days).

Tried to contact seller and Amazon to replace defective item and it just sent me through a loop over and over again. This is supposed to be a powder and instead I received a rock. In the attached pick you can see one side where I've had to literally use a knife to break it up, and the other side it is very hard like a rock. This could be a sign of spoilage or tampering and it could be serious but they have made it impossible for me to contact seller. The second picture is of me balancing a butter knife of the "powder".

I like this product because it helps my body to produce energy and aid in muscle and cardiac recovery

Tastes good.

The product is as expected and spoiled due to improper transfer and powder is like rock amulgamated very vad and no return
