How Much B12 In A Portion Of Beef Lasagne?

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

A standard portion of beef lasagne (approx. 200g-300g) typically contains between 0.6 mcg and 1.7 mcg of Vitamin B12.

This amount provides roughly 25% to 70% of the recommended daily intake (RDA) for adults (which is 2.4 mcg).

Per 100g: A 100g serving contains approximately 0.3 mcg to 0.4 mcg of B12.

Higher-End Estimates: Some nutritional data indicates that a generous, nutrient-dense serving of homemade beef lasagne can have as much as 1.7 mcg of B12.

Source: The primary source of B12 in this dish is the ground beef, with additional amounts from cheese and dairy.

Note: The exact amount depends on the amount of beef and dairy used in the recipe.

I generally eat, one Marks and Spencer’s Made Without gluten-free beef lasagne every week.
