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 [1].

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.

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.
