Plant protein blend
Pea, rice or soy protein blend. Blending improves the amino acid profile over single sources.
Evidence category: Clinical study. This describes the source category, not approval or certainty.
Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.
In a randomised crossover trial in ten healthy young adults, a pea-rice blend did not raise blood essential amino acids above pea protein alone, and whey was higher than both. A double-blind crossover trial in 14 older adults found a dairy-plant blend gave amino acid availability similar to casein and whey and higher than soy or pea alone. A dataset analysis of protein quality scores found most single plant proteins score below animal proteins, while mixtures can raise the score. Evidence is small human trials plus composition data.
Benefits reported in the imported source
- A dairy-plant blend matched casein and whey for amino acid availability in older adults
- Mixing plant proteins can raise protein quality scores above single plant sources
Risks and limits
- Most single plant proteins score below animal proteins on protein quality
- A pea-rice blend was no better than pea alone, and whey beat both on blood amino acids
- Evidence is small human trials plus composition data
Source bottom line: Single plant proteins rank below animal proteins, while blends can match dairy on amino acid availability.

Study protocols — reports, not instructions
10 healthy young adults (4 men, 6 women), mean age 22
- Reported regimen
- a single bolus of 0.3 g protein per kg body mass in 400 ml water, as a pea-rice blend, pea isolate or whey, in randomised crossover order
- Duration
- single dose, trials at least 5 days apart
- Reported outcome
- Plasma essential amino acid area under the curve was greater after whey than after pea or the blend, with no difference between pea and the pea-rice blend.
- Source
- Postprandial plasma aminoacidemia and indices of appetite regulation following pea-rice blend, pea isolate and whey protein ingestion in healthy young adults

14 healthy elderly subjects, mean age 67.4 years
- Reported regimen
- a single 18 g bolus in 360 ml, as a blend of 35% whey, 25% casein, 20% soy and 20% pea, or casein, whey, soy or pea alone, on visits about a week apart
- Duration
- single dose per visit
- Reported outcome
- Total amino acid availability from the blend matched casein and whey and exceeded soy and pea alone, with leucine and methionine well above the vegetable proteins.

Community and practice descriptions
Accounts of a practice are not evidence of safety or effectiveness. Words such as “standard”, “safe” or “recommended” describe the source account, not verified consensus or this wiki’s advice. Commercial and self-published citations are retained for traceability, not vendor endorsement or independent clinical corroboration.
Historical research outcome: no-verified-description · 2026-10-06
No suitable community description was independently verified in these checks. The entry remains empty; this does not establish that no practice exists elsewhere. The food-protein excerpt about quinoa and chia does not document a routine for the catalogue's plant-protein supplement.
