NAD+ Protector Stack

NMN + TMG (Trimethylglycine)

NAD+ precursors boost cellular energy but consume methyl groups in the process. TMG donates methyl groups to replenish what NAD+ synthesis uses, preventing methylation depletion.

Value Choice

This pair requires two separate supplements. Both are needed for the synergy to work.

NMN

Nicotinamide mononucleotide (NMN) is a direct precursor to NAD+, the coenzyme critical for cellular energy production and DNA repair. Levels decline with age.

TMG (Betaine)

Trimethylglycine donates methyl groups via the BHMT pathway, replenishing the methylation pool that NAD+ synthesis depletes. The essential companion to any NAD+ precursor.

How to take this pair: Take 250-1,000 mg NMN in the morning on an empty stomach to align with circadian NAD+ rhythms. Take 500-1,000 mg TMG at the same time so methyl donors are available as NAD+ synthesis proceeds. Start TMG at 500 mg and increase gradually. People with MTHFR variants should monitor for overmethylation symptoms.
