Betaine Supplementation Decreases Plasma Homocysteine in Healthy Adult Participants: A Meta-Analysis
American Journal of Clinical Nutrition.
This meta-analysis evaluated five randomized, placebo-controlled trials (206 total participants) using 4–6 g/day of betaine for 6–24 weeks. The pooled analysis examined whether betaine supplementation consistently supports healthy homocysteine metabolism across multiple study populations.
Study Design Highlights
- Study type: Meta-analysis of five randomized, placebo-controlled trials
- Participants: 206 total adults across 5 trials
- Dose: 4–6 g/day betaine
- Duration: 6–24 weeks per trial
Key Findings (What the Study Showed)
- Betaine supplementation significantly reduced plasma homocysteine by 1.23 μmol/L on average
- This represented an average reduction of approximately 11.8% from baseline
- Reductions were consistent across all five trials included in the analysis
- Important nuance: Two studies noted small increases in total cholesterol and LDL (~5–10 mg/dL). Researchers noted these modest changes may occur alongside homocysteine reductions, highlighting the importance of evaluating metabolic markers in context
Mechanism
Betaine functions as a methyl donor through the enzyme betaine-homocysteine methyltransferase (BHMT), helping convert homocysteine back into methionine in the liver and kidney. This pathway supports normal methylation processes, particularly when additional methyl donors are beneficial for maintaining metabolic balance.*

DuraBeet® Ingredient Summary & Real-World Relevance
Your liver plays a central role in managing nutrient metabolism and lipid processing while supporting normal metabolic byproducts. Many of these processes rely heavily on proper methylation balance and lipid transport pathways.
DuraBeet® (betaine) helps support normal liver and metabolic function in several important ways. Betaine contributes to phosphatidylcholine production, a compound required for assembling very-low-density lipoproteins (VLDL) that help transport triglycerides out of the liver as part of normal lipid metabolism.* Betaine also acts as a methyl donor, helping convert homocysteine back into methionine and supporting the balance of key methylation compounds such as S-adenosylmethionine (SAM) — pathways that are involved in many cellular processes including lipid metabolism and protein maintenance.* Research also shows that betaine influences metabolic signaling pathways involved in energy metabolism, mitochondrial function, and cellular stress responses.*
When metabolic demands are high due to factors such as high caloric intake, metabolic stress, alcohol intake, or imbalanced methylation pathways, nutrients like betaine help support the metabolic systems responsible for maintaining normal liver and cellular function.* DuraBeet® is not a stimulant and is not designed as a "cleanse." Instead, it provides foundational nutritional support for metabolic and methylation pathways involved in healthy liver physiology.*
