I listened in on the pitch at a race expo last weekend. I went online and read the studies too. The research supports the claims, but sample size is small.
I assume they funded the research, but didn’t confirm it.
I drink tart cherry and beet juice for the same anti inflammatory claims Altred makes. I would say both of these juices come at a hefty price tag and with a fair amount of calories per serving. The juices have some research behind them. It has been a while since I read those papers, but I imagine the sample sizes were significantly larger than the Alteed studies.
If I knew with some degree of certainty that the properties of the tart cherry or beet juices could be retained without the calories then I would pay the promo price at $30 / bottle. Not sure I could get my chin up to the bar for $50 / bottle regular price.
If I find the juice white papers I will update my post with a link(s).
Edit:
Rather than dig for a bunch of links here is a good summary on Tart Cherry Juice from TP with references at the bottom.
https://www.trainingpeaks.com/...-endurance-athletes/ I found a bunch of mixed results on beet juice, here is what appears to me to be a more complex study, which shows dosing is pretty key and individually variable:
http://www.physiology.org/...plphysiol.00372.2013 Given how variable this study shows beet juice is on results it is hard to buy in to the take 1 pill every two hours approach. It would also be a total waste of money if you were one of the poor responders that require a higher dosage. i would be far more inclined to try a tart cherry skin powder than a beet extract pill. I could have this all wrong as I am not a scientist by any stretch of the imagination.
