Protein powder is the highest-volume supplement category in South Africa. The whey-vs-plant debate has shifted in the last three years — modern plant blends close most of the amino-acid gap. Here's how to choose.
The fast call
- Cheapest cost-per-gram of protein — whey concentrate, typically the lowest cost per gram of protein on SA shelves.
- Lactose-free, low-fat option — whey isolate (90%+ protein, almost no lactose).
- Plant-based, complete amino profile — pea + brown rice blend, or pea + hemp blend. Look for a brand that lists the leucine content.
- Vegan + digestible — pea isolate with added enzymes.
Amino acid quality matters more than the source
Protein is judged on its essential amino acid profile, particularly leucine (the muscle-building trigger). Whey hits the leucine threshold at around 20 g. A pea + brown rice blend hits it at around 25 g — close enough that, for most people, dose just goes up slightly.
What to check on the label
Look for transparent amino acid disclosure and a stated leucine content per serving, for both whey and plant options — that's the number that tells you whether the blend actually hits the muscle-building threshold.
Vivid doesn't currently sell protein. We focus on stack supplements that protein powder doesn't cover.
