NOVOS looked into adding TMG (trimethylglycine) to our NMN.
After all, NOVOS is a big proponent of proper methylation and epigenetic approaches to longevity and health. However, TMG can cause in some people digestive issues and sleep problems.
We also think TMG is already too deep into the methylation pathways, not allowing the body to choose the amount of methylation for itself.
Therefore, we prefer B vitamins and substances like phosphatidylcholine, as we explain here:

We also added other substances to NOVOS that epigenetically impact longevity, like alpha-ketoglutarate, micro-dosed lithium, glycine, and more.
