Macro partitioning
Microalgae species such as Chlorella vulgaris and Arthrospira platensis provide high-quality protein with essential amino acid scores (AAS) equal to or exceeding those of animal-derived proteins, making them viable alternatives for human nutrition.
If you are looking for a high-quality protein source, consider microalgae like Chlorella or Spirulina. They contain all essential amino acids in amounts that meet or exceed the requirements for human health, rivaling the quality of animal proteins. This makes them a sustainable and effective option for meeting your daily protein needs.
Microalgae Chlorella vulgaris and Chlorella sorokiniana had AAS values of 1.10 and 1.16, respectively... animal-derived proteins are generally the highest rated... casein has the AAS values of 1.03–1.32
Why this rating
The paper is a review citing multiple primary studies with specific AAS data, though it lacks a single large-scale clinical trial on human health outcomes.

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
