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

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!!!

I have a child with autism and have found various supplements that have helped significantly over the years to mitigate some of the unfavorable symptoms of my child's ASD. This is one of those supplements that made a huge difference and is in the must-have category of filling in that nutritional gap. I decided to try this for my child after a study came out of the University of Arizona describing the benefits of D-Ribose and NADH for children with autism. D-ribose helped my child's mood improve favorably and decrease anxiety. I did not try NADH for a few months as a general rule to not try multiple new things at once. This brand is very effective and great quality and I reorder this consistently. I give my 100lb child (who is a teenager, actually) 1/2 tsp per day. I started out with one whole scoop per day and that had the OPPOSITE effect of increasing anxiety and lowering frustration tolerance and I found a very happy therapeutic dose at 1/2 tsp per day so you may want to experiment with dosing amount to find the right fit for you. The bonus is that this is a sweet powder and easily disguised in drinks. It does clump a little but I use a shaker bottle and give it a few minutes to unclump.

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.

great product really see the difference with cardiovascular endurance.

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

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

Not sure if it works or not yet. My soreness seems to last the same as no using it

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 )
