From the Guidelines
Grass-fed beef liver in methylated form should be consumed in moderation, if at all, due to the potential health risks associated with high red meat consumption, as suggested by low- to very low-certainty evidence from cohort studies 1. When considering the use of grass-fed beef liver supplements, it is essential to weigh the potential benefits against the potential risks. The supplements provide naturally occurring vitamin B12 and folate in their methylated forms, which are more bioavailable and easier for the body to utilize. However, the evidence from cohort studies assessing dietary patterns suggests that adherence to dietary patterns lower in red or processed meat is associated with a very small absolute risk reduction in major cardiometabolic and cancer outcomes 1. Some key points to consider:
- A decrease of 3 servings/wk of processed meat was associated with a very small reduced risk for major morbid cardiometabolic outcomes, including all-cause mortality, cardiovascular mortality, stroke, myocardial infarction, and type 2 diabetes 1.
- The evidence also suggests that meat consumption, particularly red and processed meat, may be associated with an increased risk of aging-related diseases, such as cancer, type 2 diabetes, and cardiovascular disease 1.
- Restricting protein intake, particularly from animal sources, may be beneficial for reducing the risk of aging-related diseases, as suggested by studies on amino acid restriction and mTOR activation 1.
- Vegetable protein sources, such as beans, lentils, tofu, and nuts, may be a healthier alternative to animal protein sources, as they contain less methionine and sulfur-rich amino acids 1. If you still wish to consume grass-fed beef liver supplements, a typical dosage ranges from 500-3000mg daily, taken with food to enhance absorption and minimize potential digestive discomfort. However, it is crucial to consult with a healthcare provider before starting any new supplement regimen, especially if you have specific health conditions or take medications.
From the Research
Grass Fed Beef Liver Methylated
- There are no research papers to assist in answering this question, as the provided studies do not mention grass fed beef liver or methylation in relation to it.
- The studies provided focus on various topics such as vitamins B-complex 2, vitamin A supplementation 3, high-dose B-complex multivitamin/mineral supplementation 4, vitamins and minerals for energy, fatigue, and cognition 5, and menaquinone-7 supplementation 6.
- None of these studies provide information on the methylation of grass fed beef liver, so it is not possible to provide a detailed answer to this question based on the available evidence.
