Brain+ Functional Latte
with HTB Activ™

HTB Activ™ is Big Bold Health's proprietary ingredient—a rare, heirloom strain of Himalayan Tartary Buckwheat, sourced and grown exclusively with US farming partners. Evolved in harsh, high-altitude climates, this plant developed an extraordinary concentration of natural defense compounds, including over 100 diverse polyphenols confirmed through clinical testing.

What sets HTB Activ™ apart is the process behind it. Seeds are grown in a living, regenerative soil microbiome, sprouted at peak nutritional potency, then gently dried and milled to preserve their bioavailability. The result is an ingredient unlike anything else on the market—one that Big Bold Health owns from farm to formula.

Sprouting is the moment a dormant seed comes to life, activating its plant intelligence in ways that become directly available to your body when consumed. As the seed sprouts, it ramps up production of protective compounds including polyphenols, flavonoids, phenolic acids, and antioxidants—reaching levels nearly 3x higher than unsprouted flour and over 15x higher than common buckwheat.

Through enzymatic activity, your body doesn't just receive more nutrients—it receives them in forms it can recognize, absorb, and utilize. Sprouting breaks down compounds into more bioavailable forms, enhances nutrient solubility, improves interaction with your digestive system, and reduces antinutrients that can interfere with absorption.

This article provides a more in-depth explanation.

Despite its name, buckwheat is classified as a pseudocereal (or "false grain") because it is used in the same culinary and nutritional ways as true grains. Buckwheat is actually a seed harvested from a broad-leafed flowering plant that is closely related to rhubarb and sorrel. Himalayan Tartary Buckwheat is an often overlooked ancient superfood that is biologically distinct, with an unusually rich polyphenol profile. Gluten-free, grain-free, and vegetarian.

Our core products are built on HTB Activ™ as a foundational ingredient, each formulated to deliver it differently based on individual needs and lifestyle.

HTB Sprout Powder is pure HTB Activ™ with nothing added. Its ready-to-eat format supercharges everyday meals with a toasted, nutty flavor that pairs well with sweet and savory recipes.

Immunity Chews are a tasty on-the-go format with added vitamins and minerals formulated for immune support.

HTB Superfood is a whole-food shake mix that blends easily as a nutritious meal replacement.

HTB Flour is an organic, gluten-free flour alternative that adds polyphenol power to traditional recipes, made from HTB in its unsprouted form.

Immune Rejuvenate™ is a targeted polyphenol matrix and Microbiome Rejuvenate® is formulated for gut health—both available in convenient capsule form, an upgrade to your daily stack.

What you eat sends information your body acts on at a cellular level, the quality of those signals is instrumental. HTB delivers a rich concentration of polyphenols that activate cellular signals across every system in your body. Sprouting increases the amount of polyphenols up to 5x, unlocking their most bioavailable nourishing form.

The Gut's Role
Polyphenols travel to the colon, where the gut microbiome converts them into smaller, highly active compounds. These metabolites absorb into the bloodstream and begin influencing systems throughout the body.

Whole Body Balance
Quercetin and delphinidin interact with key immune signaling pathways, helping the body maintain a calm, balanced immune response. Balance of the immune system is linked to how the brain ages over time.

The Brain Connection
Certain polyphenol forms are able to cross the blood-brain barrier. Once there, they may help to support the health of brain cells, their connections and regions of the brain involved with memory.

HTB Activ™ was evaluated in one of the largest placebo-controlled trials to date on the cognitive outcomes* of a single food. Participants were given an 18 gram dose for 90 days. Among those who consistently followed the daily protocol, the HTB Activ™ group showed improved cognitive abilities, less fatigue, and better sleep—with the advantage widening over placebo week after week.
