TMG / Betaine
What Is TMG (Betaine)?
TMG, short for trimethylglycine (also called betaine), is a naturally occurring compound found in foods like beetroot. It plays a role in methylation — a chemical process the body uses to process homocysteine (an amino acid that can damage blood vessels if it builds up too high) and support liver and cell function. WellBeingMora's B-Complex Plus Formula includes TMG sourced from beetroot, alongside choline and inositol, as part of its methylation-support blend.

Why Choose WellBeingMora TMG?
WellBeingMora sources its TMG specifically from beetroot, tying it to the same nitrate-and-nutrient-rich source used in the brand's Beetroot Extract, rather than a synthetic betaine source — pairing it with choline and inositol in the B-Complex Plus Formula as a combined methylation-support blend.
Top Features & Benefits
| Supports healthy homocysteine levels | Supports the body's methylation process | Sourced from beetroot |
| Works alongside choline & inositol | Supports liver methylation processes | Naturally occurring compound |
How Does It Work?
- TMG donates a methyl group (a small chemical building block) in a reaction that converts homocysteine back into methionine, an amino acid the body reuses — this is one of the body's main pathways for keeping homocysteine levels in check.
- This methylation pathway also supports liver function, since the liver relies on methylation for processing various compounds.
- TMG's effect on homocysteine is well documented, but its effect on cholesterol and heart-related outcomes is more mixed (see below) — so it's best understood as a targeted homocysteine-support ingredient, not a broad cardiovascular fix on its own.
TMG for Specific Health Concerns
| Concern | How TMG Helps |
|---|---|
| Homocysteine support | A 3-week randomized, placebo-controlled crossover trial in healthy, physically active men found that betaine supplementation significantly decreased homocysteine, with no negative effect on cholesterol, inflammation markers, or liver enzymes at the doses tested (2.5–5g/day). A separate randomized crossover study confirmed betaine reliably lowers homocysteine and raises blood betaine levels — with people carrying a specific gene variant (MTHFR) showing an even bigger rise in blood betaine after supplementation. |
| Higher-dose cholesterol effects — an honest caveat | Worth noting: a combined analysis of three randomized trials in 151 healthy adults found that a much higher dose (6g/day) increased LDL ("bad") cholesterol by about 11% and triglycerides by about 13% — meaning the benefit of lower homocysteine may be partly offset at these higher doses. This is why the full picture matters, not just one measurement in isolation. |
| Exercise & body composition | A review of human clinical trials found betaine supplementation, combined with physical activity, was linked to improvements in body composition in some studies — an area of ongoing sports nutrition research rather than a settled conclusion. |
When to Take
TMG is included as part of WellBeingMora's B-Complex Plus Formula at a lower amount (300mg, sourced from beetroot) than the higher doses (2.5–6g) used in dedicated homocysteine research — reflecting its role here as part of a broader methylation-support blend rather than a standalone high-dose betaine supplement.
Side Effects & Precautions
At the higher doses studied in dedicated trials (4–6g/day), some people experienced increases in LDL cholesterol and triglycerides, along with possible mild digestive upset. These effects were not seen in lower-dose (2.5g/day), shorter-duration studies. The 300mg dose in WellBeingMora's formula is well below the levels where these effects were observed.

Final Thoughts
TMG's homocysteine-lowering effect is one of the more consistently reproduced findings in this area of nutrition research, backed by multiple placebo-controlled human trials. The honest caveat is dose: the cholesterol trade-off only shows up at much higher doses than what's used in a multi-ingredient formula like this one. Where the evidence has a real trade-off — like the higher-dose cholesterol findings above — we've said so directly rather than only citing the studies that support the strongest claim.
FAQs
What is TMG (betaine) used for?
TMG supports the body's methylation process, primarily by helping convert homocysteine back into a reusable amino acid — supporting healthy homocysteine levels.
Does TMG really lower homocysteine?
Yes — multiple randomized, placebo-controlled trials confirm betaine reliably lowers homocysteine levels in healthy adults.
Does TMG have any downsides?
At higher doses (6g/day) used in some dedicated research, betaine raised LDL cholesterol and triglycerides even while lowering homocysteine — worth knowing honestly, though this hasn't been shown at the lower doses included in multi-ingredient formulas like WellBeingMora's B-Complex Plus.
Why is TMG sourced from beetroot specifically?
Beetroot is a natural, well-known source of TMG, and using it ties this ingredient to the same source as WellBeingMora's dedicated Beetroot Extract.
Can TMG help with exercise performance?
Some clinical research suggests betaine combined with physical activity may support body composition, though this remains an active area of sports nutrition research rather than a settled conclusion.
Is TMG safe for daily use?
At the doses used in shorter, lower-dose studies (2.5g/day), TMG appeared safe with no negative effects on cholesterol or liver enzymes. Higher-dose, longer-term use should factor in the cholesterol findings above.
What's the difference between TMG and choline?
Both support methylation, but TMG acts directly on homocysteine conversion, while choline is a precursor the body can convert into betaine itself. WellBeingMora's B-Complex Plus includes both alongside inositol for a fuller methylation-support blend.
How much TMG is in WellBeingMora's formula?
300mg per serving, sourced from beetroot — a supporting dose within a broader methylation blend, not a standalone high-dose betaine product.
Does everyone respond to TMG the same way?
Not quite — people carrying a specific gene variant (MTHFR) tend to show a bigger rise in blood betaine levels after supplementation, though homocysteine still drops in most people regardless of genotype.
