On Healing Horizons with Saima, David Hunter—founder of Global Phytoplankton—explains why the ocean’s tiniest plants may be the most overlooked source of cellular nutrition. We cover what makes phytoplankton different from spirulina/chlorella, its dense micronutrient and omega-3 profile, and why its microscopic size may support mitochondrial function and energy. David connects ocean ecology, sustainability, and practical wellness: foundational nutrition, digestion, sleep, skin, and vitality. This direct, science-curious conversation separates hype from first principles and explores where phytoplankton fits in a modern nutrition stack. Guest: David Hunter.
About the guest :
David Hunter is the founder of Global Phytoplankton. For nearly two decades he has focused on cultivating marine phytoplankton for human and pet nutrition, advocating a “first principles” approach that starts with base-level micronutrients from the oceanic food chain.
Key takeaways:
-
Foundation first: Phytoplankton is positioned as the planet’s base food source and a concentrated provider of micronutrients, antioxidants, and omega-3 precursors that support whole-body wellness.
-
Cell-level framing: Because phytoplankton is microscopic, David argues it can nourish the mitochondria—the cell’s “engine”—without heavy digestive burden.
-
Broad nutrient coverage: Rather than guessing single-nutrient fixes (e.g., just iron or magnesium), a broad-spectrum input may help address multiple minor deficiencies at once.
-
Ecology ↔ humans: Ocean health and human health are linked. Phytoplankton generates significant planetary oxygen and sits at the start of marine food chains that ultimately supply omega-3s.
-
Complement, don’t replace: Even if adding phytoplankton, smart basics still matter: balanced diet, hydration, sleep, stress management, and professional medical guidance.
-
Pets, too (anecdotal): David reports pet owners noticing mobility and energy shifts in older dogs; these are anecdotal and should not replace veterinary care.
-
Quality & consistency: If you experiment with any supplement, monitor dose, timing, and personal response; buy from reputable producers and consult your clinician if you have conditions, are pregnant, or take medications.
-
Sustainability note: Interest is growing in marine micro-nutrition that supports human vitality while encouraging responsible ocean stewardship.
