Lowering homocysteine with TMG
Homocysteine drops fast on TMG both times I started it — and the one big spike turned out to be travel, diet, and short sleep, not the supplement.
The numbers
| date | homocysteine |
|---|---|
| 2024-10-31 | 10.08 |
| 2025-06-05 | 10.76 |
| 2025-07-29 | 7.42 |
| 2025-10-29 | 8.09 |
| 2025-12-16 | 7.29 |
| 2026-03-12 | 11.48 |
| 2026-04-16 | 9.89 |
| 2026-06-11 | 8.82 |
What I did
- TMG 1 g, mornings · 2025-06-16 → 2025-07-10. Homocysteine went 10.76 → 7.42 within six weeks of starting.
- Off TMG through the autumn → drifted back up to 8.09.
- TMG 2 g, mornings · restarted 2025-11-11, ongoing. Next draw: 7.29.
Co-interventions I can't fully separate: methyl B-12 (1 mg daily) started four days after the first TMG run; methylfolate (every other day) added 2026-01.
The spike, explained
The 11.48 on 2026-03-12 stood out — the highest reading in the series, and I was still on 2 g TMG daily. It isn't a mystery anymore.
The two to three months before that draw were the worst-controlled stretch of the year: travelling, eating out most days, a worse diet overall, and short sleep in the couple of weeks right before the blood test. Homocysteine tracks exactly that — B-vitamin intake and the folate/B12 status behind it — so a spike there is what you'd expect, TMG or not.
Once the normal routine came back, so did the number: 9.89 a month later, then 8.82 on 2026-06-11, back near the on-TMG baseline (and that June draw also followed a short-sleep week — the low end of "normal for me").
So the honest read isn't "TMG fixed it and it stays fixed." It's "TMG lowers it, and diet + sleep can push it right back up." Both levers matter, and the March draw is the proof of the second one — I'm keeping it in the record for exactly that reason.
