/ 100
PoorExcellent

Verdict: moderate

Marmite Yeast Extract earns a moderate score of 60/100 primarily due to its intense sodium content, which offsets its beneficial B-vitamin fortification.

Key takeaways

  • 4000mg sodium per 100g
  • Excellent source of B-vitamins
  • Contains 34g protein per 100g
  • Highly sustainable yeast-based source
  • Extremely low sugar at 0.5g

Our read on this product

Marmite Yeast Extract holds a respectable health score of 60/100, largely supported by its exceptional B-vitamin profile including Thiamin, Riboflavin, and B12. However, the nutritional profile is heavily impacted by a massive sodium content of 4000mg per 100g, which poses cardiovascular concerns if overconsumed. While it is low in fat and sugar, the ultra-processed nature of the yeast extract means it functions best as a small flavor enhancer rather than a staple food. Its ability to provide 34g of protein is notable, though the serving size necessary to reach that level would exceed safe sodium limits.

Best for

Marmite Yeast Extract is suitable for vegetarians and vegans looking for a rich source of B-vitamins and savory umami flavor.

Approach with care

Individuals with hypertension or those on strict low-sodium diets should avoid this product entirely due to the extreme salt concentration.

Good

Yeast Extract

Concentrated yeast extract is the core ingredient providing the signature umami flavor and richness. It is a natural source of B vitamins, though highly processed to achieve its dense, spreadable consistency.

Watch out

Salt

Used as a flavor enhancer and a primary preservative for shelf stability. Excess sodium intake is linked to elevated blood pressure and cardiovascular strain.

Neutral

Vegetable Juice Concentrate

Used to add depth and natural sweetness to the savory profile. It is derived from plant sources and is generally considered a neutral, processed additive.

Good

Vitamins (Thiamin, Riboflavin, Niacin, Vitamin B12, Folic Acid)

These are added to fortify the product for nutritional value. They are essential micronutrients that support energy metabolism and nerve function.
