Questions regarding NMN dosage and volume

Why is nmn so expensive? By my research you’d need to spend around £200 a month to dose yourself properly

Yes NMN is relatively expensive, as it is very complicated and expensive to make to a clean, high purity. We do our best to keep the price as low as possible. Our NMN is verified by third party labs to be of the highest quality in terms of purity, heavy metal content and microbial content.
NMN is less expensive than it was a couple of years ago, and the long term price trend is downwards.

You can find prices and pack sizes at the main NMN page here:

The recommended dosage is 0.5g per day, and upper dosage is 1g per day.

The price for 100 grams is £382.82 - or £363.68 if paying via bank transfer. This would work out at £54.55 per month if taking 0.5g per day, or £109.10 per month if taking 1g per day.
Some people like to take a day or two off per week. If taking NMN on 5 out of the 7 days per week, this would drop the monthly price down to around £36.37 per month for 0.5g per day, or £72.74 per month for 1g per day.
