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!)

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 started taking this at my massage therapist's recommendation. Normally, things that work for me show the benefit pretty quick (a matter of days). So when I hadn't noticed any appreciable improvement to my daily stamina, I assumed it wasn't going to work for me. Kept taking it though, and a few days later realized I still had energy when I got home from work. My thoughts were clear, I didn't need to take a nap, and my sleep patterns appeared to improve. I chose this brand/volume because of its good ranking, and it had a good value (ratio of cost to volume compared to others). I was concerned with the bad taste some reviewers reported, so I 'hide' it in a mixture of grapefruit juice and water. I don't find a bad taste with that mix, and I'm pretty sensitive to these things...after chemotherapy years ago, many former nice things weren't so appealing due to a chemical aftertaste. I take 5g in the morning with breakfast, then sip on a 5g mix that I take to work in a sealed cup. Keeps me going even though I'm on my feet all day. Then I come home with enough mental/physical energy left to act like a real human being for a few hours before bedtime. I will do my best to follow up in a month or two to report any further changes/improvement. ====== OK, it's been over a month, and I'm still pleased with this product. It took about two weeks for it to be effective for me. I now have it on subscription purchase.

This is the second brand I've tried of D-Ribose powder I've tried, and I really like this brand! I like it infinitely more than the other brand I tried - it cost a bit more, but 1 measure of this is equal to 5 grams of D-Ribose, and 1 measure of the other was equal to 2 grams (the measures were the same size). I mix this into some yogurt, or a small amount of Powerade, and it's tasteless - which for me is a good thing. I don't want to add any taste to what I'm eating or drinking when I'm taking powdered supplements. Sometimes I add it to my powdered Creatine and Glutamine - which also are tasteless. I hate to have to choke down bitter or nasty tasting supplements - I just can't do it! There is a slight smell - not a bad smell, but when you open the bottle you can smell it - it smells exactly like other D-Ribose products I've tried - so it smells like it should smell I'm sure! As far as performance, this is FAR superior to the last D-Ribose, even though the last product was a great brand - one I trust. This product just happens to be better. I was relying on Amazon reviews and it really paid off! People seemed very happy with this product, now you can add me to the list! I suffer from Chronic Fatigue and FMS, and I'm always trying to find that magic bullet. This helps with energy, along with the other supplements I'm taking. I'm still working on the perfect combo, and the 3 I've listed, as well as L-Carnitine, are vital to helping me get out of bed each day. I hope this is helpful to someone out there, if it helps just one person I'll be happy to have written this review. The only thing I'm having a problem with, and it might be a BIG problem for some, is that this supplement seems to be making me gain weight. I don't like that. There hasn't been any other change, so I assume that's what it is. Also, there was no weight gain when I took other brands of d-ribose, so I assume it's this. The benefits so far keep me using this brand. Recommend!

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

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