What Makes Himalayan Tartary Buckwheat Sprout Powder Unique

What Makes HTB Rejuvenate Unique
Himalayan Tartary Buckwheat is a powerhouse of a plant, capable of surviving at the extremes of environmental pressure. In order to thrive where other plants cannot, HTB produces exceptionally high levels of plant molecules called polyphenols. The bran of Himalayan Tartary Buckwheat is especially fortified with these nutrients, and these may help promote a healthier gut microbiome.
Quercetin and luteolin are notable polyphenols found naturally in Himalayan Tartary Buckwheat. They have been studied for their effects on immune function, and may influence a number of pathways related to immune balance.

About Big Bold Health
Big Bold Health is revitalizing a nutritious crop that disappeared from Western agriculture many decades ago. We have established a grower co-op of family farms in a rural region of upstate New York at the northern edge of Appalachia. Our flour is organic, grain-free, gluten-free, and non-GMO. It is artisanally milled and packaged in small batches just a few miles from the fields where it is grown and harvested.
