Our read on this product

Scoring 45/100, the Fulfil Vitamin & Protein Bar highlights the trade-offs in modern sports nutrition. The use of milk protein provides a solid amino acid profile, yet this is offset by the inclusion of sucralose and soy lecithin. The high calorie density of 385 kcal per 100g makes it a heavy snack option for those not engaging in intense physical training. Ultimately, it prioritizes performance metrics over ingredient clean-label standards.

Best for

This bar is designed for athletes and active individuals who require high protein intake for muscle maintenance and recovery.

Approach with care

Individuals sensitive to artificial sweeteners like sucralose or those with dairy and soy allergies should avoid this product.

Ingredients to watch

Sucralose: Watch out
Neutral

Milk Protein

Derived from milk, this provides a complete amino acid profile to support muscle maintenance and satiety. While highly nutritious, high consumption of processed dairy proteins can potentially trigger acne in some sensitive individuals.

Neutral

Polydextrose

A soluble fiber used as a bulking agent and sugar substitute to improve texture. It has a low glycemic impact but may cause digestive discomfort or bloating if consumed in large quantities.

Neutral

Soy Lecithin

An emulsifier extracted from soybeans that helps maintain product consistency and stability. It is generally recognized as safe, though it is a common allergen and highly processed.

Watch out

Sucralose

An artificial intense sweetener used to provide sweetness without calories. While FDA-approved, some studies suggest potential long-term impacts on gut microbiome diversity.
