Life ExtensionD-Ribose Powder, Dissolve in Liquid to Encourage Cellular Energy Production and Support Heart and Muscle Health, Gluten-Free, Non-GMO, Vegetarian, 150 Grams

I don't know if it's working yet, but I put it in my coffee along with my boron and my l.lysine easy way to get it in, thankfully I use very dark roast with protein powder, so I don't taste any of it

Excellent preduction for real athletes I recommend it, I am running like never before.

I bought to help my 2 dogs who suffer from heart murmurs. They like the taste and my dogs are not suffering from pain so I don't know if they are benefitting that way. The product came in a quality made tub with a scoop which helped alot. The price was comparable to others I've used.

I always cycle on this when I feel exhausted.I definitely helps . I use it in my unsweet iced green tea ( it’s very much like a sweetener and better than stevia or cane sugar )

I hope this review is helpful to others. I had a positive experience, but there are things that may have contributed, as well. One thing important to say right away - Life Extension products are excellent.BACKGROUND INFO: Male, 40 yrs old. I do Brazilian Jiu Jitsu and weight training. I work in an engineering field. I need to be completely honest that I have not tried this product ALONE, but with a group of other products that make us what is called The Awesome Foursome, which consists of: Reacted Magnesium (1x/day); Carnitine(1x/day); CoQ10(1x/day); D-Ribose(2x/day). Also, be aware that I take other supplements: fish oil (3x/day), trans-resveratrol(1x/day), Vit D3 (5000 IU/day), Myomin (3x/day), and slow release DHEA (20mg, 1x/day).DOSAGE: I take one scoop, twice a day (morning and late afternoon).VERDICT: Since adding TAF to my supplement regime, I have seen a very noticeable improvement in my mental focus at work and performance in BJJ, as well as weight lifting. There's no nervous caffeine jitters or restlessness, just simple alertness and focus. My cardio performance during intense BJJ sessions has also noticeably improved. I think this has a two part reason: mental focus allows for less wasted energy via better technique; true energy production improvement in the muscle cells.I have also noticed that my mood is much, much better. Productivity at work is up, and I am more patient and positive, which has made for home-life to be much more enjoyable for all - I got pretty cranky at night due to all the physical demands of my hobbies :). My wife has noticed the old happy me coming back.One bit of advice: For any supplement, I recommend trying it for at least two weeks before grading its performance. I typically try only one supplement at a time, but I tried all four of TAF together for a month, and I definitely noticed a difference. I may scale back one supplement at a time to see if anything changes, as it will be an expensive long-term commitment for all four, considering my already expensive supplement regime.If you're interested in taking all four of TAF, I don't recommend doing what I did. Instead, add only one at a time, and see if you get an improvement. My total expense for TAF is about $70/month. Ouch!!!

My doctor suggested I try this to start healing and strengthening my mitochondria and it has helped with my energy levels! I definitely recommend.

This is the very 1st time I tried the Supplemental powder. I was hoping it would become a supplement that would help me With my energy. I was made aware that if one's stomach is fermenting D-ribose will make it ferment worse. I'm not sure if that's the case with me however I stop taking it after 5-6 days I don't think it has anything to do with the product more to do with my health.I stopped taking it as it did seem to be giving me an upset stomach.

I like the product..
