ProHealth Longevity | TMG Supplements (Trimethylglycine)

Our verdict

ProHealth Longevity | TMG Supplements (Trimethylglycine) works out to $0.14 per serving of betaine (tmg), at 1000mg per serving in tablet form. That puts it around the median of the 16 betaine (tmg) products we can price per dose, where the typical serving costs $0.13, a Value Index of 0.9 where the median product is 1.0. One container lasts 120 days at the label dose of 1 serving a day, about $4.14 a month. We could not verify a third-party certification for ProHealth in a public registry.
