TMG Rhonda Patrick: The Surprising Supplement She Swears By for Energy, Longevity & Heart Health
If you’re curious about optimizing your health you’ve probably come across the name Rhonda Patrick. Known for her deep dives into nutrition and wellness Dr. Patrick often highlights the benefits of TMG—short for trimethylglycine—as part of a smart supplement routine.
You might wonder why TMG gets so much attention and how it fits into your daily health strategy. Whether you’re aiming to boost energy or support longevity understanding TMG through Rhonda Patrick’s research could help you make more informed choices for your well-being.
Who Is Rhonda Patrick?
Dr. Rhonda Patrick, PhD, is a biomedical scientist focused on nutritional health, longevity, cellular biology, and micronutrient supplementation. You find her research and public discussions address how substances like TMG (trimethylglycine), methylation processes, and micronutrients impact DNA regulation, energy metabolism, and cognitive function. Notable platforms featuring her expertise include publications like Cell Metabolism, her FoundMyFitness channel, and appearances on podcasts such as The Joe Rogan Experience.
You see Dr. Patrick provide evidence-based recommendations for health optimization, referencing human trials, peer-reviewed studies, and mechanistic data. Key themes in her work include the effects of diet, sauna therapy, vitamins, and supplements—examples include TMG, vitamin D, omega-3s, and magnesium—on inflammation, aging, and disease risk. Her PhD from the University of Tennessee and postdoctoral research at Children’s Hospital Oakland Research Institute anchor her credibility.
What Is TMG?
TMG, or trimethylglycine, is a natural compound found in beetroot, spinach, and whole grains like quinoa. You support cellular processes when TMG donates methyl groups, small molecules essential for the methylation of DNA, proteins, and lipids. TMG assists in the conversion of homocysteine to methionine, a critical step for cardiovascular health, as described in research from the National Institutes of Health.
You often see TMG referenced in the context of methylation pathways, which impact your DNA repair, liver function, and neurotransmitter synthesis. Rhonda Patrick notes that adequate TMG intake supports these methylation reactions, especially if your diet is low in folate or vitamin B12—two key cofactors. For example, individuals with elevated homocysteine, as found in some clinical studies, can experience reduced levels when supplementing with TMG.
TMG appears in a variety of foods, yet supplementation provides a concentrated dose, commonly ranging from 500 mg to 2,500 mg daily. Possible effects include improved metabolic health, better methylation status, and support for athletic performance. Peer-reviewed evidence cited by Dr. Patrick suggests a connection between TMG and these health outcomes, though its impact varies by individual.

Rhonda Patrick’s Research on TMG
Dr. Rhonda Patrick’s investigations into TMG examine how this compound influences health at the cellular and systemic levels. You’ll find detailed explanations and recommendations from her work, based on clinical and mechanistic evidence.
Potential Benefits Highlighted by Rhonda Patrick
Dr. Patrick identifies key benefits of TMG intake, including enhanced methylation status, reduced homocysteine, and improved physical performance. Clinical studies cited in her research find that TMG supplementation supports efficient DNA methylation and lowers homocysteine concentrations—an established marker for cardiovascular risk—especially in people with suboptimal folate or B12 intake. Strength and endurance athletes, for example, see improved muscle power and reduced fatigue after TMG use. Some users report subjective increases in cognitive clarity and metabolic energy, corroborated by pilot clinical data.
Mechanisms of Action Discussed
Dr. Patrick delineates TMG’s methyl donor capacity as central to its mechanisms. TMG donates methyl groups, facilitating the methylation of homocysteine to methionine. This reaction contributes to the synthesis of S-adenosylmethionine (SAM-e), a critical substrate in DNA, protein, and neurotransmitter methylation. Her published reviews discuss how TMG’s functions interconnect with B-vitamins and the folate cycle, influencing gene expression and energy pathways. For cardiovascular health, this methylation loop supports normal plasma homocysteine levels, which peer-reviewed data link to reduced cardiovascular disease risk.

How to Use TMG According to Rhonda Patrick
Dr. Rhonda Patrick outlines practical guidelines for integrating trimethylglycine (TMG) into your health routine. Her recommendations balance evidence from human trials and clinical mechanisms, focusing on safe, effective use.
Recommended Dosages and Forms
Rhonda Patrick recommends supplementing TMG with daily intake ranges from 500 mg to 2,500 mg, based on published intervention studies, individual needs, and dietary intake of folate or vitamin B12. Capsules and powder are the most common supplement forms, with powder offering customizable dosing for precise intake. Food sources like beetroot and spinach provide TMG, though most users seeking measurable clinical effects opt for supplemental forms. For advanced health objectives—such as homocysteine reduction or methylation support—Dr. Patrick prioritizes daily TMG alongside a B-vitamin-rich diet.
Possible Side Effects and Considerations
Dr. Patrick describes TMG as well-tolerated for most, citing minimal side effects in peer-reviewed studies. You might experience mild digestive symptoms—such as nausea or stomach upset—at higher doses or with sensitive digestive systems. Cases of increased body odor or rare allergic responses appear in clinical reports but remain infrequent. She advises discussing supplementation with a healthcare provider, especially if you take prescription medications, have kidney disease, or manage methylation disorders. For best results, Dr. Patrick suggests co-supplementing TMG with adequate folate and vitamin B12 to support balanced methylation.

Comparisons With Other Methylation Supplements
Trimethylglycine (TMG) stands out among methylation supplements for its direct role as a methyl donor, supporting efficient homocysteine-to-methionine conversion. Compared to folate (examples: methylfolate, folic acid), TMG operates downstream in the methylation cycle, benefiting those with folate or B12 insufficiency by providing alternative support for methylation pathways. Supplementing with TMG provides an advantage in individuals with genetic MTHFR variations (source: NIH), where folate metabolism is compromised.
Vitamin B12 (examples: methylcobalamin, adenosylcobalamin) acts as a cofactor for homocysteine remethylation but depends on adequate folate status. TMG works independently, complementing B12 action and covering potential gaps in methylation, especially in plant-based diets with low B12 intake. SAM-e (S-adenosylmethionine) directly delivers active methyl groups, but SAM-e supplements lack the broad dietary presence and affordability of TMG.
Niacin (vitamin B3) impacts methylation by consuming methyl groups during metabolism, indirectly influencing homocysteine levels and methylation capacity. TMG supplementation addresses the increased demand for methyl groups induced by higher niacin intake.
Clinical trials compare TMG with methylfolate and B12, showing equivalent reductions in homocysteine in populations with adequate vitamin status (source: American Journal of Clinical Nutrition, 2016). In athletic performance studies, TMG outperforms placebo and matches creatine in supporting muscle output and recovery.
| Supplement | Main Role in Methylation | Dietary Sources | Standout Feature |
|---|---|---|---|
| TMG | Direct methyl donor (homocysteine → methionine) | Beets, spinach | Works independently of folate/B12 |
| Methylfolate | Folate cycle entry, DNA methylation | Leafy greens | Central to MTHFR gene variations |
| B12 | Cofactor for homocysteine remethylation | Animal products | Essential for vegetarians/vegans |
| SAM-e | Universal methyl donor | Limited dietary | Direct methyl group provider |
| Niacin | Consumes methyl groups, regulates methyl self-sufficiency | Animal/plant foods | Modulates demand for methyl donors |
