Yellow-Eye Mullet

Food · Protein · Food, Typed Supps

An overlooked fish that’s unusually rich in B12 and selenium.

Stage by stage

Intake (Chewing): Chewing breaks down its protein and fat structure.
Stomach (Protein digestion begins): Stomach enzymes begin breaking down the fish protein.
Small intestine (B12 & minerals absorbed): B12, selenium, zinc and omega-3 fats are absorbed in the small intestine.
Bloodstream & immune tissue (Red blood cells & immune support): B12 supports red blood cell formation and nerve function; selenium and zinc support immune activity.

Timing

Any meal — its fat content helps carry the omega-3 it supplies.

Time to effect

Weeks: B12 stores build up with regular intake, since the liver holds several years’ worth in reserve.

Allergens

Contains: Fish. Derived from what this food is, not from a product label.

Eating patterns

Fits: Pescatarian, Kosher, Keto, Gluten-free. Depends on the product: Halal, Low-FODMAP.

Satiety

167 on the satiety index, where white bread is 100 — high. Modelled from the Holt et al. (1995) measurements.

Environmental footprint

13.6 kg CO2e and 3691 litres of freshwater per kg, matched to "Fish (farmed)" in Poore & Nemecek (2018), Science 360.

Cost band

Mid — roughly £11 per kg, as a band midpoint rather than a price.

Food vs. supplement

A 100g serving supplies close to double the daily B12 requirement and more than a full day’s selenium from one whole food — output that would otherwise take two separate supplements.

Kitchen tip

Pan-fry or grill whole — its oilier flesh holds up well to higher heat and doesn’t dry out as fast as leaner fish.

Common myth

"Fish sold mainly as bait has no real nutritional value." In reality: Yellow-eye mullet is a genuinely dense source of B12 and selenium — its use as bait reflects its price and abundance, not its nutrient content.
