In a recent episode of the Doctor Bob Martin Show, Hardy Nutritionals’ Product Development Scientist Dallin Hardy joined Dr. Adam Brockman for a deep, science-forward conversation on a question more people are asking every year:

What if the missing piece in mental and physical wellness isn’t another prescription—but proper nutrition at a cellular level?

With mental health challenges, stress, brain fog, and mood instability on the rise, the discussion centered on how broad-spectrum micronutrients—specifically those found in Daily Essential Nutrients (DEN)—support brain function in a way isolated nutrients and symptom-targeted approaches cannot.

From Animal Nutrition to Human Mental Health

Dallin shared the origins of Hardy Nutritionals, founded by his father, David Hardy, whose background was originally in animal nutrition and agricultural science.

In animal health, supplementation is not controversial—it’s foundational. Farmers know that animals thrive only when they receive a complete, balanced spectrum of nutrients at meaningful doses. Those that don’t supplement… don’t stay in business.

What David Hardy noticed when transitioning into human nutrition was a striking contradiction:

• Humans are often skeptical of vitamins and minerals

• Yet readily accept powerful pharmaceutical drugs—often without fully understanding their risks

That disconnect became personal when broad-spectrum micronutrient protocols were used successfully within their own family to support recovery from severe mental health challenges. Those outcomes solidified the shift toward human nutrition and ultimately led to the development of Daily Essential Nutrients.

What “Broad-Spectrum” Actually Means (and Why It Matters)

At first glance, DEN may resemble a multivitamin. But as Dallin explained, the similarities stop at the label.

Broad-spectrum micronutrition means:

• Every essential vitamin

• Every essential mineral

• Trace minerals often missing from standard supplements

• Delivered in clinically meaningful doses

• Balanced to avoid deficiencies and nutrient imbalances

Most one-a-day multivitamins are constrained by capsule size and consumer expectations. As a result, they must sacrifice either:

• Comprehensiveness, or

• Dose

Daily Essential Nutrients does neither.

Clinical research on DEN uses 12 capsules per day, divided across meals—not because “more is better,” but because this mirrors how the body absorbs nutrients from food and allows enzymes to function optimally throughout the day.

The Biochemistry Behind Mental Wellness

Dallin offered a clear analogy from biochemistry:

Think of metabolism as an interconnected network of assembly lines.

• The workers are enzymes

• Roughly 50% of enzymes require vitamin or mineral cofactors to function

If even one required nutrient is missing, the entire system slows down—especially in energy-intensive organs like the brain.

The brain represents only about 2% of body weight, yet consumes roughly 20% of the body’s energy. Every essential vitamin and mineral plays a role in mitochondrial energy production. Supporting brain health, therefore, requires all nutrients working together, not isolated supplementation.

This is why single-nutrient strategies often fall short—and why broad-spectrum approaches show such wide-ranging benefits.

Why Minimum Intake Isn’t Enough

Government dietary recommendations (RDAs / Daily Values) are designed to prevent overt deficiency diseases—not to optimize healing, resilience, or neurological function.

In clinical contexts, especially when someone is already under stress or experiencing mental health symptoms, nutrient needs are higher. Research consistently shows that bringing the body into an optimal nutrient range—above deficiency but well below toxicity—can meaningfully support recovery.

This therapeutic window is wide for vitamins and minerals because they are native to human physiology, unlike pharmaceuticals that often have narrow safety margins.

A Research-Backed, Systems-Level Approach

Hardy Nutritionals’ research portfolio is unusually robust in mental health nutrition. Independent, peer-reviewed studies using DEN have explored outcomes across:

• Depression

• Anxiety

• ADHD

• Bipolar disorder

• Autism spectrum conditions

• Traumatic brain injury

• Stress and emotional regulation

• Antenatal and postpartum mental health

Rather than targeting a single diagnosis, the research consistently points to improved global functioning—a measure that reflects real-world quality of life, emotional stability, and resilience.

This systems-level effect explains why integrative physicians and mental health practitioners increasingly view broad-spectrum micronutrients as a foundational first step, especially before escalating to more invasive interventions.

Nutrition Has Changed—Our Biology Hasn’t

Modern food systems look abundant, but nutrient density has quietly declined due to:

• Rapid crop growth

• Soil depletion

• Irrigation practices

• Ultra-processed foods

Dallin shared an agricultural parallel: livestock grazing on fast-growing, lush grass can suffer fatal mineral deficiencies unless supplemented. The grass looks healthy—but it isn’t complete.

Human food systems face a similar challenge. Appearance doesn’t equal nutrient sufficiency.

The Takeaway

The conversation on the Doctor Bob Martin Show reinforces a core Hardy Nutritionals principle:

Mental wellness is not a mystery—it is biology.

When the brain receives the full spectrum of essential nutrients it requires, at the right doses and in the right balance, it is better equipped to regulate mood, manage stress, support cognition, and heal.

Broad-spectrum micronutrition doesn’t replace medical care—but it restores the foundation upon which mental and physical health depend.

Daily Essential Nutrients (DEN) contains every essential vitamin and mineral science has shown to be required for optimal human health in precisely balanced ratios, delivered in a highly bioavailable format. This broad-spectrum approach is what sets Daily Essential Nutrients apart and has attracted the attention of university researchers, textbook authors, health practitioners, and researchers worldwide.
