Food as Medicine. Proven.
Does the quality of our diet impact us? Can real food influence brain wellness?
One of the largest controlled trials of a single food set out to find the answer.
The key background research
This work builds on earlier research on Tartary buckwheat compounds, and a study on high polyphenol diets. Together, they pointed in the same direction.
Tartary buckwheat and the biology of aging
Researchers studied how Tartary buckwheat compounds, including rutin, quercetin, and luteolin, may influence key biological markers tied to how the immune system ages. The findings connected real food to longevity, immune balance, and metabolic health.‡

Key Findings: 47% reduction in the rate of biological aging over 90 days among the fastest-aging participants.
Study used a concentrate of phytonutrients based around Himalayan Tartary Buckwheat, a separate formulation from HTB Activ. Exploratory pilot study. Single-arm design. Results varied across participants.¹
A high polyphenol diet and healthier brain aging
In a clinical brain-MRI trial, participants who followed a diet high in polyphenols, including green tea, walnuts, and Mankai, experienced significantly slower brain aging, alongside improvements in blood sugar metabolism over 18 months.‡

Key Findings: ~50% reduced advancement of brain-aging over 18 months of observation.

A landmark trial measuring the cognitive outcome of a single food
18g
A randomized, double-blind, trial compared an 18 gram daily dose of HTB Activ™ against a matched placebo.
82%
At baseline, 82% of participants showed room for corrective support in attention or focus over the previous 3 months.
49
Average age of participants was 49, ranging from 21-79 years, 63% of which were female.
662
850 enrolled initially, with 662 active participants over a 12 week (90-day) period.
One of the largest placebo-controlled trials to date on the cognitive outcomes of food.
Data analysis revealed several findings which were statistically significant compared to placebo.³
Discover what real food can do
90% of participants taking HTB Activ™ reported a meaningful shift in how they felt day to day, in relation to cognition, sleep, mood & fatigue.
Cognitive Ability +69%
People taking HTB Activ™ reported meaningful improvement in cognitive abilities—a statistically significant result. Among those who closely followed the protocol, improvement was 31% greater than the placebo group.†§
63% Better Sleep
People taking HTB Activ™ reported meaningful improvement in sleep. Those who consistently followed the protocol experienced more improvement over placebo—a statistically significant result.†§
66% Less Fatigue
People taking HTB Activ™ experienced less fatigue. Those who consistently followed the protocol experienced more improvement over placebo—a statistically significant result.†§
31% Brighter Mood
People taking HTB Activ™ reported meaningful improvement in their mood, While not statistically significant, it is worth watching closely as the research continues.†
Cognitive Speed +20%
People taking HTB Activ™ experienced a roughly 20% faster reaction time on a cognitive test (Flanker Squared) compared to their speed at the start of the study—with no loss in accuracy.†

Beyond the Label
Most food databases track around 150 nutrients. But real food contains more than 139,000 natural compounds, and scientists have barely scratched the surface of what they do.
Researchers have a name for this gap: they call it "the dark matter of nutrition." It's a massive layer of biological information hidden inside everyday food that science is only just beginning to understand.
Polyphenols make up a significant portion of those 139,000+ compounds that science has yet to fully understand. They sit at the center of nutrition's dark matter. Himalayan Tartary Buckwheat Sprout Powder (as HTB Activ™) is one of the most polyphenol-dense food sources, which lends itself well to this exploration.⁴
Nutritional power isn't found in a single nutrient. It's unlocked through the complexity of real food.
For a century, nutrition science hunted for the single magic molecule—one vitamin, one compound, one pill. But the body doesn't read food that way. Real food speaks in networks: hundreds of molecules acting together, sending signals that help program how our cells, brains, and immune systems behave.
One nutrient at a time doesn't work
Decades of nutrition research focused on single nutrients in isolation. That approach missed the point. Food is complex by design, and studying it piece by piece leaves out the bigger picture.
Plant compounds are built to work together
Polyphenols, the powerful plant compounds found in foods like berries and grains, naturally travel together through the food supply. They share the same biological origins and act on the same targets inside the body. They're designed to team up, not work alone.
Food works through a network effect
A single food touches pathways throughout the body. Food doesn’t just influence one thing; it works across multiple systems at once, like a master key that unlocks several doors simultaneously.
How polyphenols speak to the body and brain
Food works in ways science is still mapping. These proposed pathways reflect the current scientific thinking on how polyphenols may communicate with the body and influence how people feel, think, and function.*
Antioxidant
Helping neutralize the oxidative stress that wears down cells and tissues over time.*
Epigenetic
Influencing how genes are switched on or off, the way nutrients help program our biology.*
Metabolic
Supporting healthy blood sugar and steady energy, two factors closely tied to how the brain ages.*
Microbiome
Feeding the gut ecosystem that shapes immunity, mood, and the gut–brain axis.*
Immune
Helping calm and balance immune signaling, a system deeply linked to brain health.*
Add polyphenols to your patient protocol
Sprouting unlocks an incredible world of plant molecules
Independent laboratory testing identified up to 80 individual phytonutrients in HTB Activ™ including polyphenol concentrations hundreds of times higher than those found in common buckwheat.⁵
Same plant family.
Very different chemistry.
RUTIN
RUTIN
(Quercetin-3-rutinoside) One of the most abundant polyphenol in HTB Activ™, increasing 2–5× during sprouting to reach levels 313× higher than common buckwheat.
Supports antioxidant activity and helps strengthen the integrity of small blood vessels.*
QUERCETIN
QUERCETIN
(Flavonol aglycone) Forms naturally when rutin breaks down during sprouting, reaching levels 167× higher than common buckwheat.
Supports immune balance, helps protect cellular energy systems, promotes vascular health, and has been studied for its role in brain resilience.*
DELPHINIDIN
DELPHINIDIN
(Anthocyanidin aglycone) Elevated in sprouts compared to seeds. Supports the body's antioxidant response and plays an active role in cellular signaling.
Notably, it crosses the blood-brain barrier, where it may help support a healthy, balanced immune response in the brain.*
HOMOERIODICTYOL
HOMOERIODICTYOL
(Methylated flavanone) Rare in most food sources and uniquely elevated during sprouting through the plant's natural stress response.
Influences how the body perceives bitter taste, supports the response to oxidative stress, and plays a role in healthy hormonal signaling.*

How the food you eat connects to the brain
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.
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.
This is what taking food seriously looks like—not chasing a single nutrient, but harnessing the full, complex intelligence of an ancient superfood. In one of our largest trials, that complexity was noticed in the 90% of participants taking HTB Activ™ who reported meaningful positive changes in cognition, sleep, mood and fatigue.
