Health and nutrition
Benefits, risks, and dosage without the greenwash.
Algae can be useful, but quality, contaminant testing, iodine level, and product form decide whether a recommendation is responsible.
Algea system
Health and nutrition connects science, buyers, products, and supply.
Evidence and safety
The health layer is a buying guide and a risk guide.
55-70%
Protein density
Spirulina dry weight is frequently cited for high protein, but product quality depends on origin and testing.
Dose matters
Iodine caution
Seaweed can be useful for iodine intake but risky for thyroid-sensitive users when labels are vague.
Phyco + asta
Pigment value
Phycocyanin and astaxanthin are key commercial pigments spanning supplements, cosmetics, and colorants.
COA first
Testing standard
Heavy metals, microcystins, microbial load, and origin should be checked before any recommendation.
Next step
Turn algae curiosity into a working decision.
Move from learning to comparing, sourcing, or reading deeper research.
