Form Nutrition Review 2026: Plant-Based Protein and Supplements for Triathletes

What Is Form Nutrition?

Form Nutrition is a UK-based plant-based sports nutrition brand that has built a strong following among endurance athletes who want effective, clean supplements without animal-derived ingredients. Founded with a focus on sustainability and performance, Form’s range covers protein powders, pre-workout capsules and sleep recovery supplements — all vegan, all third-party tested and all free from artificial colours and sweeteners.

The Core Range: What’s Available

Performance Protein — £26 (13 servings, 520g)

Form’s flagship protein powder uses a blend of pea, rice and pumpkin seed proteins to achieve a complete amino acid profile. Each serving delivers 20g protein and 150 calories with no artificial flavouring — the Chocolate Peanut variant is genuinely good. For triathletes, this fills the post-swim or post-turbo protein window cleanly, without the bloating some athletes experience from whey-based proteins on high-volume training days.

Superblend Protein — £26 (13 servings, 520g)

The Superblend upgrades the protein base with added digestive enzymes and a broader blend of plant proteins including hemp and fava bean, targeting athletes who train twice a day and need fast uptake between sessions. The Chocolate Salted Caramel flavour is the bestseller and mixes cleanly with water or oat milk without clumping.

Performance Capsules

Edge — Caffeine Capsules — £19 (60 capsules)

Edge is Form’s pre-race caffeine supplement, delivering 100mg of caffeine per capsule alongside L-theanine to blunt the jitteriness that can accompany high-dose caffeine intake. For triathletes, taking 1-2 capsules 45 minutes before a race is a clean, no-sugar way to activate the caffeine performance benefit without the glycaemic spike of caffeinated gels. Useful in the 30-minute pre-race window when solid food isn’t practical.

Boost — Pre-Workout Capsules — £19 (30 capsules)

Boost takes the Edge formula further with added beta-alanine and creatine for training sessions where you’re targeting quality over volume — interval sessions, FTP tests, vo2max efforts. Unlike most pre-workouts it’s in capsule form rather than a powder drink, which makes dosing more precise and avoids the gastrointestinal risk of high-carb pre-workout drinks before swim training.

ZZZZs — Sleep Recovery Capsules — £19 (30 capsules)

Recovery is where triathlon performance is actually built, and sleep quality is the biggest lever most age groupers can pull without changing training volume. Form’s ZZZZs capsules combine magnesium glycinate, L-theanine and chamomile extract to support sleep onset and quality. Third-party tested for banned substances — safe for competition use.

Verdict

Form Nutrition is the most compelling plant-based sports nutrition brand currently available in the UK for triathletes. The protein powders are genuinely palatable (rare for plant-based products), the capsule supplements are well-dosed and clearly formulated for endurance athletes rather than bodybuilders, and the price point is fair given the ingredient quality. If you’re plant-based or simply want to reduce reliance on animal-derived supplements, Form is the brand to start with.
