Plant-Based Protein: Benefits, Best Uses, Timing, and What to Look For

What Is Plant-Based Protein?

Plant-based (vegan) protein powder is described by Healthylife as an alternative to whey or casein proteins, suitable for vegans and vegetarians, and also potentially useful for people with allergies or intolerances. (Source: Healthylife – Vegan protein powders)

Healthylife also lists common plant-based options such as soy, pea and hemp proteins, noting rice protein is often mixed with other plant proteins to “complete its amino profile.” (Source: Healthylife – Protein powder supplements (category page))

How Plant-Based Protein Works in the Body

Myprotein explains that pea and rice proteins can be complementary proteins: pea protein is lower in methionine and higher in lysine, while rice protein is higher in methionine and lower in lysine, and combining them increases levels of both amino acids compared with either alone. (Source: Myprotein AU – Whey vs plant protein (complementary proteins))

Myprotein’s nutritionist guide states its Vegan Protein Blend combines pea protein, brown rice protein and hemp protein to create a “full amino acid profile” in a vegan shake. (Source: Myprotein AU – Which protein powder is right for you?)

Key Benefits: What the Evidence Says (from These Sources)

1) A practical way to increase protein intake without dairy

Myprotein describes vegan protein as a good option for people with allergies and intolerances and states it doesn’t contain any dairy, is “naturally gluten-free,” and “hypoallergenic” (as described on their page). It also states that a 25g serving provides between 18g and 20g of plant protein (as described on their page). (Source: Myprotein AU – Vegan protein in the lab)

2) Muscle support positioning (pea protein as a high-quality protein source)

Myprotein’s plant-based protein powders article states pea protein has been shown to be a high-quality protein source with evidence suggesting it can have the same effect on muscle mass as whey protein (as described on their page). (Source: Myprotein AU – Best plant-based protein powders)

3) Protein between meals (and “while you sleep” positioning)

Myprotein describes milk/casein powders as “packed with slow-releasing protein” that can help grow and maintain muscle between meals and even while you sleep. (This is included here as a comparison point because many people choosing plant-based proteins are comparing them with milk-based proteins.) (Source: Myprotein AU – Milk & casein category)

Whether plant-based protein provides the same “slow-release” properties as casein: Not specified on the source page.

Common plant protein sources (examples from allowed merchants)

• True Protein describes “Vegan 85” as a tri-blend made from pumpkin, pea and brown rice. (Source: True Protein – Vegan protein powders collection)
