Plant Based Protein
Plant proteins for anyone avoiding dairy entirely. The important thing to check is whether the sources are combined, because most single plant proteins are incomplete on their own.
What to look for in a plant protein
Most single plant proteins are limited in at least one essential amino acid. Rice protein is low in lysine. Pea protein is low in methionine. Combining them covers both, which is why rice and pea blends are the standard rather than a marketing gimmick.
Leucine is the one to watch. Leucine triggers muscle protein synthesis, and plant proteins are generally lower in it than whey. That is why plant protein servings are often larger, and why some products add extra leucine directly. Check the panel.
Digestibility matters too. Plant proteins score lower than whey on digestibility measures, so a slightly larger serving is reasonable rather than excessive.
And if you are avoiding dairy but not animal products entirely, egg white protein is worth knowing about. It is a complete protein in a single source with no combining required, and naturally higher in leucine than most plant options.

Why plant proteins are blended
Most single plant sources are limited in at least one essential amino acid. Combining them fixes it.
| Rice protein | Low in lysine Pea protein |
So a rice and pea blend is not marketing. It is the reason the category works at all.
Leucine is the one to watch. Leucine triggers muscle protein synthesis and plant proteins are generally lower in it than whey. That is why plant servings are often larger, and why some products add leucine directly. Check the panel.
What to expect, honestly
Plant protein has improved enormously. It is still not identical to whey.
exture is grittier. Pea and rice protein have a particle size that never fully disappears the way whey does. Blending with liquid rather than shaking, or mixing into a smoothie, helps considerably.
Digestibility scores lower than whey on standard measures, which is why a slightly larger serving is reasonable rather than excessive.
Taste is stronger. Earthy notes from pea protein are part of the ingredient rather than a fault, and chocolate flavours generally mask it better than vanilla.
And if you are avoiding dairy but not animal products entirely, egg white protein is worth knowing about. Complete in a single source, no combining required, and naturally higher in leucine than most plant options.
