Chlorella
Overview
Chlorella is a microalgae providing protein, chlorophyll, and bioavailable vitamin B12 (true cobalamin forms in validated preparations) unlike many spirulina products [1]. It is used in supplement-scale portions for micronutrient and protein density.
Within the BRAIN Diet framework, chlorella can help close B12 gaps in plant-forward patterns when a validated algae source is used
Key Nutritional Highlights
- Microalgae protein with validated true B12 in some preparations [1].
- Very high table protein per 100 g; typical use is supplement grams/day.
- Source quality matters for B12 form (cobalamin vs analogues).
- Introduce gradually; GI tolerance varies.
Food Context
Synergies
- Part of functional food strategy
Sourcing
- Choose quality sources with confirmed B12 content
Preparation
- Available as powder, tablets, or capsules
- Important for vegan B12 intake
Essential Amino Acid Profile
Chlorella contribute plant protein. Pair with complementary protein sources (e.g. grains and legumes) for a balanced essential amino acid profile.
