Product Overview
Big Bold Health HTB Rejuvenate® Superfood is a vanilla whole-food shake mix built around HTB Activ™, Big Bold Health's proprietary sprouted Himalayan Tartary Buckwheat ingredient. Each serving combines 17 grams of protein with fiber, vitamins, minerals, amino acids, and a broad spectrum of plant polyphenols for convenient daily nutrition and support for metabolic health, microbiome diversity, immune resilience, and healthy aging.*
Best For
- Adding 17 grams of protein to a smoothie or daily shake
- Increasing dietary polyphenol and phytonutrient diversity
- Supporting healthy muscle and protein intake*
- Supporting metabolic health and healthy aging*
- Supporting microbiome diversity and gut health*
- Adults looking for a more complete nutritional option than a simple protein powder
More Than a Protein Shake
There are plenty of protein powders. There are also plenty of greens powders, vitamin mixes, fiber supplements, and products built around one heavily marketed plant compound.
HTB Rejuvenate® Superfood takes a different approach.
The formula starts with protein and adds fiber, vitamins, minerals, amino acids, and HTB Activ™, a sprouted Himalayan Tartary Buckwheat ingredient naturally rich in a diverse range of polyphenols.
The result is a versatile daily shake that combines straightforward nutritional value with the phytonutrient diversity that has made Himalayan Tartary Buckwheat increasingly interesting in functional nutrition and longevity medicine.
17 Grams of Protein Per Serving
Protein is one of the most practical reasons to use HTB Rejuvenate® Superfood. Each full serving provides 17 grams of protein, making it useful at breakfast, between meals, after exercise, or whenever daily protein intake needs some help.
Adequate protein becomes increasingly important with age. Maintaining lean mass requires more than exercise alone, and many adults simply do not consume enough high-quality protein consistently throughout the day.
For longevity medicine, that matters. Muscle supports strength, mobility, glucose disposal, metabolic health, physical independence, and resilience later in life.*

Powered by HTB Activ™
What separates HTB Rejuvenate® Superfood from an ordinary protein shake is HTB Activ™, Big Bold Health's proprietary Himalayan Tartary Buckwheat ingredient.
Himalayan Tartary Buckwheat is an ancient pseudocereal with an unusually diverse phytochemical profile. Big Bold Health reports that HTB Activ™ contains more than 100 naturally occurring polyphenols, including flavonoids associated with Tartary buckwheat such as rutin, quercetin, and hesperidin.
HTB Activ™ is grown with U.S. farming partners, sprouted, gently dried, and milled. Sprouting changes the seed's biochemistry as germination begins, increasing the activity and availability of a variety of naturally occurring plant compounds.
A full suggested serving of HTB Rejuvenate® Superfood provides 500 mg of HTB Activ™.
Why Polyphenol Diversity Is Interesting
Polyphenols are not one nutrient. They are a large family of plant compounds found in vegetables, fruits, herbs, tea, cocoa, berries, and other plant foods.
Much of their biology appears to come from interaction rather than from acting as simple antioxidants. Polyphenols can participate in cellular signaling and interact with the intestinal microbiome, where bacteria transform many of them into additional metabolites.
This has made polyphenol diversity increasingly interesting in research involving metabolism, inflammatory signaling, vascular health, gut physiology, cellular stress responses, and healthy aging.
Himalayan Tartary Buckwheat stands out because it supplies many of these compounds together within a food-derived matrix rather than reducing the conversation to one isolated flavonoid.
For a deeper look at the science, see Polyphenols, Immunometabolism, and Longevity Medicine.
Fiber and the Microbiome
HTB Rejuvenate® Superfood also provides dietary fiber, giving the shake another advantage over protein products focused almost entirely on amino acids.
Fiber helps support normal bowel function and provides substrate for selected intestinal microbes.* Polyphenols also interact with the microbiome, creating an interesting overlap between plant diversity, microbial metabolism, and gut-immune signaling.
No individual food can manufacture a healthy microbiome by itself. Regular intake of varied plant foods, adequate fiber, movement, sleep, metabolic health, and thoughtful use of targeted microbiome support remain the larger picture.

Vitamins, Minerals, and Amino Acids
HTB Rejuvenate® Superfood is formulated as more than an HTB delivery system. It also supplies a broad range of vitamins and minerals along with added amino acids.
This makes it particularly useful when convenience matters. Instead of combining a basic protein powder with several separate nutritional additions, HTB Rejuvenate® brings protein, fiber, micronutrients, amino acids, and polyphenols together in one shake.
That does not mean every person needs every nutrient in the formula. It does make the product considerably more nutritionally complete than the original HormoneSynergy® description suggested.
How to Use HTB Rejuvenate® Superfood
Mix 1 to 2 scoops with 8 to 12 ounces of water or milk. It can also be blended into smoothies, bowls, or other recipes.
The manufacturer's suggested full serving is 2 scoops, providing 500 mg of HTB Activ™.
The subtle vanilla flavor is designed to complement the naturally nutty character of Himalayan Tartary Buckwheat.

HTB Sprout Powder vs. HTB Rejuvenate® Superfood
Big Bold Health offers Himalayan Tartary Buckwheat in several forms, and the distinction is useful.
Himalayan Tartary Buckwheat Sprout Powder is the simpler option. It is essentially HTB Activ™ as a whole-food ingredient that can be added to meals, smoothies, yogurt, and recipes.
HTB Rejuvenate® Superfood is the more complete nutritional formula. It uses HTB Activ™ within a shake that also provides protein, fiber, vitamins, minerals, and amino acids.
For someone primarily interested in adding Himalayan Tartary Buckwheat to an existing diet, the sprout powder may make more sense. For someone who also wants protein and broader nutritional support in one shake, Rejuvenate® Superfood offers considerably more.
The HormoneSynergy® Perspective
We particularly like the combination here because it addresses two different parts of healthy aging without making the product unnecessarily complicated.
The first is practical: adequate protein matters for maintaining muscle, strength, recovery, and metabolic health as we age.*
The second is nutritional diversity. HTB Activ™ adds a broad plant-polyphenol matrix that is very different from what most protein powders provide.
That makes HTB Rejuvenate® Superfood less of a conventional supplement and more of a functional nutrition tool: protein, fiber, micronutrients, and an unusual whole-food phytonutrient source in a format that is easy to use consistently.
