How Much B12 In An M & S Liver And Bacon For One?

I asked Google AI, the title of this post and received this answer.

An M&S Lamb’s Liver and Bacon meal (typically 450g for one) is an exceptionally high source of Vitamin B12 due to the high concentration in liver, likely providing well over 100 µg (micrograms) of B12 per pack.

Key Facts Regarding B12 in M&S Liver and Bacon:

Liver Density: Lamb’s liver contains roughly 85–90 micrograms of Vitamin B12 per 100g.

Component Breakdown: The 450g meal contains approximately 16% liver (approx. 72g of liver).

Total Content Estimate: Based on the 72g of liver, a single 450g meal likely contains roughly 60–70 µg of Vitamin B12, which is over 2,000% of the daily recommended intake.

Additional Sources: The bacon and gravy also contribute to this total.

The UK Reference Nutrient Intake (RNI) for adults is 1.5 micrograms daily, making this meal a significant source.

As I wuld have expected, this ready meal is a good source of B12.
