Studies show a clear benefit for lowering homocysteine by raising folate to adequate levels, but theres no additional benefit seen from adding more folate for people who already get plenty of folate.[ref][ref] Decreasing animal protein (maybe): Higher levels of dietary methionine, such as from a diet high in animal protein, can increase homocysteine levels.[ref] However, a high-protein diet usually contains more vitamin B12, vitamin B6, betaine, and folate, which may offset the increase in methionine in real life.[ref] In laboratory settings, people who eat foods high in methionine alone show an increase in homocysteine, but this is attenuated when the increased methionine is consumed along with other amino acids.[ref] Natural vitamins and supplements for decreasing homocysteine: Folate: Dozens of studies and placebo-controlled clinical trials show that increasing folate can lower high homocysteine levels
