What’s inside this formula?
Fast&Up’s Yeast Protein — Unflavoured is listed here in the yeast protein collection. This article looks at the selected 500 g; 13 servings pack, then puts its ingredients into context.
The manufacturer lists 26 g protein per serving from yeast protein isolate, with inulin, added enzymes and Bacillus probiotics. Yeast is a microorganism, rather than a plant protein source.
Check the original label ↗Yeast-derived protein is an alternative to dairy and common plant-protein sources. The nutritional comparison still begins with protein grams, amino acids and the complete formula. Emerging research on specific yeast proteins is useful context, but it should not be treated as proof that every yeast product outperforms established options.
The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.
Where might it be useful?
Protein supply
Yeast protein can contribute amino acids as part of the overall diet.
An alternative ingredient
It may offer a practical protein-source option when its formula and dietary status fit the user’s preferences.
What the research can — and cannot — tell us
A controlled trial has studied yeast protein alongside whey and exercise, but the evidence base is less extensive than the general protein literature. Results depend on the studied ingredient, population and training programme. They do not establish clinical superiority of this exact retail product.
What deserves your attention?
Check the current scoop weight and amino-acid panel, and consider inulin tolerance. A manufacturer protein-quality score does not establish clinical superiority. Listing availability changed between source snapshots; confirm at the seller.
Suitability comes before strength
Check the full formula and any yeast-related allergy or intolerance. A dairy-free ingredient does not by itself verify all allergen claims; discuss protein restriction or medical conditions with a clinician.
Dietary details for this product
Vegetarian The manufacturer explicitly identifies this yeast-derived, non-dairy formula as suitable for vegetarians. Whole-formula vegan certification was not independently checked.
A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
