While we need methionine and protein in the diet, one way to increase homocysteine is to significantly increase dietary methionine without a concomitant increase in choline, B12, or folate.[ref] Timing of testing: Homocysteine levels are lowest in the first hour after a meal, so if you test your homocysteine level after eating, it will likely be different than what a fasting blood test will show.[ref] Down syndrome, CBS, and low homocysteine: People with Down syndrome usually have very low homocysteine levels due to the extra copy of chromosome 21, which causes an extra copy of the CBS gene
Considerations: Bioavailability may be lower compared to injections
Remember that you can also naturally boost your vitamin B12 levels by consuming more food sources of vitamin B12, including beef liver, organic meats and wild-caught salmon
