Marine Phytoplankton Guide

Marine phytoplankton is the most nutrient-dense organism on the planet by dry weight and also one of the most overhyped in supplement marketing. This section covers what the evidence actually supports, from EPA content and bioavailability through to safety, sustainability and how cultivation method affects what ends up in the capsule.

The Basics

What Is Marine Phytoplankton? The organism itself: species, taxonomy and what makes it nutritionally distinct from other algae. Marine Phytoplankton Nutrition Facts EPA, chlorophyll, carotenoids and amino acids: what whole-cell phytoplankton actually contains. What Is Nannochloropsis gaditana? The specific species used in most phytoplankton supplements and why it was selected for EPA content. Nannochloropsis Benefits and Nutrition A closer look at the nutrient profile, EFSA-authorised claims and practical supplementation guidance.

Evidence and Health Claims

Marine Phytoplankton Benefits: What the Evidence Says Clinical and observational evidence reviewed, with clear boundaries between what is established and what is not. Does Marine Phytoplankton Contain EPA? The headline question for anyone considering phytoplankton as an omega-3 source, answered at species level. Does Marine Phytoplankton Contain DHA? Why most phytoplankton species do not deliver meaningful DHA and what that means for your supplement strategy. Clinical Research on Marine Phytoplankton What the published studies actually tested, what they found and where the gaps remain.

Safety and Practical Guidance

Is Marine Phytoplankton Safe? Toxicology, contraindications and what to check before adding phytoplankton to your routine. Marine Phytoplankton Side Effects Documented side effects, drug interactions and realistic expectations for daily use. How to Choose a Supplement Species, cultivation method and label transparency: the three things that separate useful products from marketing. Overstated Claims About Marine Phytoplankton Common marketing claims that outrun the evidence, and how to spot them.

Production and Sustainability

How Marine Phytoplankton Is Grown Open ponds vs closed photobioreactors: how cultivation method affects purity, consistency and price. Is Marine Phytoplankton Sustainable? Land use, water use, carbon footprint and the environmental case for algae-based supplements. Vegan Nutrition and Phytoplankton Where phytoplankton fits in a plant-based diet and what it does and does not replace.

Comparisons

Phytoplankton vs Other Microalgae How marine phytoplankton compares to chlorella, spirulina and other algae supplements. Marine Phytoplankton vs Fish Oil EPA source, bioavailability, contaminant risk and cost: a head-to-head comparison. Marine Phytoplankton vs Algae Oil Whole-cell phytoplankton vs extracted Schizochytrium oil: different products for different needs. Marine Phytoplankton vs Krill Oil Phospholipid-bound omega-3 from two very different sources. What the evidence says about each. Phytoplankton vs Spirulina One produces EPA, the other does not. A nutritional comparison that matters more than most people realise.
