WHOLE SUPP Review 2026: Meal-Replacement Shakes Tested for Triathlon Training
Overview
Whole Supp is a UK plant-based meal-replacement shake brand built around whole-food ingredients rather than the isolate-heavy formulas common in most protein powders. For triathletes juggling early swims, work and evening sessions, a shake that covers a proper meal in 30 seconds is a genuinely useful tool — as long as it doesn’t taste like chalk or unsettle your stomach before a session. Here’s what’s actually in it, what it costs, and who it suits.

Key Specs
- Protein — 31g of plant-based protein per serving (100g / 2 scoops)
- Calories — 400kcal per serving, with 40-41g carbohydrate and 12-13g fat
- Ingredients — built around 13 whole-food ingredients including pea protein, brown rice protein and whole oats, plus 30+ vitamins and minerals
- Dietary — vegan, gluten-free and soy-free
- Flavours — Chocolate, Caramel Sea Salt and Strawberry
- Yield — one bag makes 15 meals
Why It’s Different From a Standard Protein Shake
Most protein powders are built to hit a single number — grams of protein per scoop — and leave you to source the rest of a meal’s worth of nutrition elsewhere. Whole Supp is positioned as a full meal replacement rather than a post-workout topper: alongside the 31g of protein you get meaningful fibre (4.8-6.7g per serving) and a full micronutrient spread, which is the point of building the formula around whole foods rather than isolates. It’s a genuinely useful option for the pre-dawn swim session where a proper breakfast isn’t realistic, or the evening after a long turbo session when cooking is the last thing you want to do.
What Others Say
Whole Supp has picked up a following beyond age-group triathletes. Tottenham Hotspur’s performance nutritionist consultant Mark Evans has recommended it to players: “I’ve found Whole Supp to be more filling and palatable than other powder formulations, made even more impressive because it’s a plant-based product. I will be recommending and using Whole Supp with my athletes.”
Price and Availability
A bag (15 meals) costs £33.99 as a one-off purchase, or £26.85 on a Subscribe & Save plan — working out at around £2.26 per meal, which is competitive against most meal-replacement and protein blends once you account for the fact it’s replacing a meal rather than supplementing one.
Verdict: Who It’s For
Whole Supp suits triathletes who need a genuine meal replacement rather than a post-workout protein top-up — particularly useful around early sessions or on packed training days when a proper cooked meal isn’t going to happen. If you’re only after a straightforward recovery protein shake to have alongside food, a cheaper whey or plant protein powder will do that job for less; Whole Supp earns its higher per-serving cost by replacing the meal outright.
