Many cellular functions are influenced by methyl groups, such as DNA methylation and phosphatidylcholine synthesis. The methyl food donors, folate methionine, and betaine can provide methyl groups. To act as a donor of methyl, betaine is not required for the addition of folate.

It is not possible to determine the nutritional needs of folate, methyl, choline, and betaine donors for farm animals. These nutrients are not available in diet formulation software, animal simulator models, or diet formula programs. An insufficient supply of methyl donors can cause inflammation.

In addition, recent evidence suggests that methyl donors activate adenosine monophosphate-activated protein kinase, a major anti-inflammatory switch, that dietary supplements containing methyl donors can be used to prevent or ameliorate chronic inflammation and its effects in livestock, including fatty liver. 

Betaine can also come from food sources. Betaine can also be converted into DMG by donating homocysteine-methyl strips. This pathway is mediated through BHMT, which is an enzyme that's induced by betaine and inhibited.

Research suggests that folic acid deficiencies can be partially treated with choline. Folic acid-deficient rats' livers were low in phosphatidylcholine and cholines. Folate stores in the liver decrease when folate is consumed on a low-choline diet.
