Yes, Vitamin B3 does appear to be beneficial for boosting 1-methylnicotinamide (1-MNA) levels. Here's what the research shows:

What the Evidence Says

According to Pillser's research database, there is 1 study specifically examining Vitamin B3 for increasing 1-methylnicotinamide levels, and that study showed a beneficial effect¹².

The Metabolic Connection

This makes biochemical sense. Vitamin B3 (which includes niacin, nicotinamide, and nicotinamide riboside) is converted in the body into NAD+. NAD+ is further broken down into nicotinamide, which is then methylated by the enzyme nicotinamide N-methyltransferase (NNMT) to produce 1-methylnicotinamide (1-MNA). So supplementing with Vitamin B3 provides more substrate for this pathway.

Regarding Dosage

Pillser's database does not specify the exact dosage used in the available study. However, based on general knowledge of the metabolic pathway:

• Doses of nicotinamide in the range of 500–1,500 mg per day are commonly used in research contexts for NAD+ precursor effects, which would be expected to increase downstream metabolites like 1-MNA.
• Nicotinamide riboside is often dosed at 250–500 mg per day.
• Niacin dosing for metabolic effects typically starts at 250–500 mg per day, though niacin can cause flushing at higher doses.

Since the specific dosage data from the Pillser study isn't detailed, it would be best to refer to the research directly for exact dosing parameters.
