June 2 2016
Betalains are a class of red and yellow indole-derived pigments found in plants of the Caryophyllales, where they replace anthocyanin pigments.

J Nutr Science. 2014. Effects of a beetroot juice with high neobetanin
content on the early-phase insulin response in healthy volunteers. Produce rich
in phytochemicals may alter postprandial glucose and insulin responses by
interacting with the pathways that regulate glucose uptake and insulin secretion
in humans. The aims of the present study were to assess the phytochemical
constituents of red beetroot juice and to measure the postprandial glucose and
insulin responses elicited by either 225 ml beetroot juice (BEET), a control
beverage matched for macronutrient content (MCON) or a glucose beverage in
healthy adults. Beetroot juice was a particularly rich source of betalain
degradation compounds. The orange/yellow pigment neobetanin was measured in
particularly high quantities (providing 1·3 g in the 225 ml). A total of sixteen
healthy individuals were recruited, and consumed the test meals in a controlled
single-blind cross-over design. Results revealed a significant lowering of the
postprandial insulin response in the early phase (0-60 min) and a significantly
lower glucose response in the 0-30 min phase in the BEET treatment
compared with MCON. Betalains, polyphenols and dietary nitrate found in the
beetroot juice may each contribute to the observed differences in the
postprandial insulin concentration.
Q. I would like your unbiased opinion of the merit of betalains extracted from
beets. There is a company called Evolv that has a product called "limitless" and
they promote the production of "Prolain" which is a process they are patenting
in which they were able to separate the betalaine from the sugar and make a
supplement. They are making many claims. It's supposed to help with
osteoporosis, energy . I would love to be enlightened as to its
effectiveness and research that has been done in this area...I have osteo in my
knees. I've just lost 40 pounds to alleviate the pain and plan to lose 25 more
pounds. I'm on Celebrex, but I'm told that it's not good for your stomach over a
long period. I'm just exploring other solutions...
