Vegan Protein Powder

Is vegan protein powder as good as whey?

For most people, a well-made plant protein can do the same job as whey: add protein to your day. The evidence is thinner, though. The International Society of Sports Nutrition (ISSN) says research on plant proteins such as pea, rice and hemp is limited, although one study found rice protein comparable to whey in resistance-trained people.

The ISSN also says whey has an advantage over soy for the short-term muscle response after a single serving, partly because of its amino acid make-up. In practice, the total protein you eat across the day matters more than which powder supplies part of it. Compare plant options with our whey protein range if you're not fully dairy-free.

What is vegan protein powder made from?

Most vegan protein powders are made from pea, brown rice, soy or hemp protein, either on their own or blended together. Blends are common because each plant source has a slightly different amino acid profile and texture.

The Vegan Society notes that pea and soya-based foods are usually high in protein, and that hemp seeds can make a useful contribution. Check the ingredients list for the protein sources, the sweetener and any thickeners, and whether the product is a plain protein or a blend with added carbohydrates, as some recovery products are.

How much protein do vegans need?

The UK recommends 0.75g of protein per kilogram of body weight a day for adults, and the Vegan Society says vegans may need a higher protein intake, suggesting around 1g per kilogram. It adds that most people don't need to work out their protein requirement.

If you train regularly, the British Dietetic Association says people in strength and endurance sports need around 1.4 to 2.0g per kilogram a day, and that a healthy, balanced diet should usually provide it. A powder is a convenient top-up, not a requirement.

Is plant protein a complete protein?

Yes, in the sense that plant proteins contain every essential amino acid. The Vegan Society says plant proteins contain all the essential amino acids, and that a varied, balanced diet gives you a good mix across the day.

Individual sources contain them in different proportions, which is one reason pea and rice are often blended. If the label shows an amino acid profile, you can compare the leucine per serving: the ISSN suggests each protein dose should aim for 700 to 3,000mg of leucine and 20 to 40g of protein.

Is all plant-based protein powder vegan?

Not always. "Plant-based" describes the protein source, but a product can still contain milk-derived ingredients or be made on lines that handle milk, so look for a clear vegan statement on the label. Several product names in this collection say "vegan", but we still suggest you check the label of the exact tub you buy.

Check allergens too. Soybeans are one of the 14 allergens that must be emphasised in the ingredients list, and the NHS lists peas and soybeans among the most common allergic foods. Pea-free, soy-free and gluten-free options exist, so read the label rather than assuming.

How do you compare vegan protein powder on value?

Compare the cost per 25g of protein, not the price of the tub. Plant powders range widely in protein per 100g, so a cheaper tub can cost more for the protein you actually get.

"The amount of protein on the front of the packaging doesn't always tell you which product offers the best value," says Andy Arshad, who runs SupplementHQ. "When we compare products from different brands and wholesalers, serving sizes, protein concentrations and the number of servings per tub vary considerably. Two products can look similarly priced, but once you calculate the actual cost per 25g of protein, the value can be quite different."

How to compare value (example figures, not real products): a £25 tub of 750g at 70% protein contains 525g of protein, or 21 portions of 25g, so it costs about £1.19 per 25g. A £30 tub of 1kg at 80% protein contains 800g, or 32 portions, so it costs about 94p per 25g. The more expensive tub is better value.

What does protein actually do?

The authorised claims for protein in Great Britain are that "protein contributes to a growth in muscle mass", "protein contributes to the maintenance of muscle mass" and "protein contributes to the maintenance of normal bones". These can only be used where a food is at least a source of protein, which most protein powders are.

Plant protein carries the same claims as any other protein; no source has extra authorised claims. Being vegan also means planning for nutrients such as vitamin B12, and the NHS says a vitamin B12 supplement may be needed. See our vitamins & supplements for that.

Which is the best vegan protein powder?

The best one for you fits your diet and allergies, gives a useful amount of protein per serving and costs a sensible amount per 25g of protein. Taste and mixability matter too, because plant powders can be thicker or grittier than whey.

"Sometimes the premium is justified by formulation, testing or ingredient quality, but sometimes customers are paying mainly for branding," says Andy. Start with the protein per serving, check the vegan statement and allergens, then work out the cost per 25g. Our guide to reading a supplement label shows where to find each figure, and you can compare across every type in our protein powder hub.
