Should I stack NMN with TMG (trimethylglycine)?

There is a theoretical case. NMN supplementation increases methyl group consumption (NAD+ metabolism uses methyls); TMG donates methyls and stabilises homocysteine. The animal data is suggestive, the human data is sparse. If you have elevated homocysteine on a routine blood test, methylation support is reasonable - and TMG is cheap (RM30-50 per month). If your homocysteine is normal, the marginal benefit is unclear. Standard pairing dose: 500mg TMG with each 250mg NMN. Avoid stacking TMG if you have low blood pressure, as it can drop further.

Why this matters for Malaysian buyers

NMN buying decisions in Malaysia involve a stack of considerations that don't always map to advice from US- or EU-focused sources: NPRA notification status, JAKIM halal certification (or its absence), tropical-climate storage realities, mall pharmacy versus Shopee Malaysia tradeoffs, and how local medical practitioners typically respond to questions about supplements outside their training. We answer questions like "Should I stack NMN with TMG (trimethylglycine)?" through the lens of Malaysian buyer realities - not generic global guidance.
