Which same compound in Edam Cheese and Lamb

[Guest guest]

I heard a health show a few days ago,

mentioning a compound in both Edam Cheese

and lamb (not Vitamin Bs), were helpful for ???

I lost my notes. It was definitely not Vit Bs,

it could be an amino acids or something else.

Whenever I had one type of palpitations, eating

Edam Cheese or lamb were very helpful. This means,

I am deficient in ???? I haven't be able to find out since,

which compound it is.

Anyone knows???

Many thanks,
