Jinfiniti NMN Supplements Personal Case Study

A good jump in NAD levels and grip strength during this one month trial, but not everything improved

I decided to give NMN another try, having previously tested it quite thoroughly with DoNotAge’s supplement, but at the time I wasn’t aware of Jinfiniti’s intracellular NAD test, so although many secondary biomarkers improved I didn’t have a definitive measurement. Similarly, I trialled Tru Niagen NR which only pushed my NAD level up a small amount, so I was interested to retest NMN with a proper before and after NAD test. Fortunately, I had the opportunity to do this when I won a pack of 2 tests and a month’s supply of NMN in a promotion – however, as always, this blog post is editorially independent with no input from Jinfiniti.

My NAD Grand Challenge prize:

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in all living cells that plays a crucial role in cellular energy production and metabolism. It helps to facilitate reactions that generate energy from glucose, fatty acids, and amino acids, and is also involved in DNA repair and gene expression.

Studies suggest that as we age, NAD+ levels decline, which may contribute to age-related diseases and cellular dysfunction. By supplementing with NMN, it may be possible to increase NAD+ levels and potentially improve cellular function and overall health. Nicotinamide mononucleotide (NMN) is a molecule that is converted into NAD+ in the body. More details about NAD (and the NAD+ salvage pathway) in this previous NMN blog.

Accuri Vitality Boost Review

As well as their excellent NAD test, Jinfiniti also sell their own NMN formulation – Accuri Vitality Boost – which is half NMN and half a mixture of creatine monohydrate, D-Ribose and nicotinamide. Importantly, it is manufactured under GMP (good manufacturing practice) which ensures a high-quality production. More details here:

The recommended dose is one scoop (1000 mg, of which 500 mg is NMN) twice a day – so I took mine first thing in the morning and after lunch. The suggested method for best absorption is to dissolve it in a little bit of cold water first (just enough to dissolve it by stirring) then drink it sip by sip, keeping each sip in the mouth for 30-45 seconds to get mucosal absorption. Initially I found this a bit inconvenient, but after a couple of day I got used to doing something else whilst holding a sip in my mouth.

The powder dissolved pretty quickly (under a minute) with the photos below showing what it looks like after a quick swirl in water, though occasionally I had to crush a particularly big lump of powder with a teaspoon. The final photo shows what is left after drinking the liquid, but a final dash of water meant none was wasted.


NAD Level

All of the physical biomarker results below, and secondary effects of any changes to the body’s NAD levels – i.e. this is the key, and most direct, result.

I tested for intracellular NAD before and after taking NMN. In fact, I did the “after” test before I ran out of NMN, to make sure my levels were at their peak, and also to pick a day when the post was most likely to speed my sample to the Jinfiniti lab as quickly as possible.

I previously reviewed Jinfiniti’s NAD test, but in summary it’s easy to perform, particularly when I followed the “soak hands in warm water for 2 minutes” instructions which resulted in easily producing 8 big drops of blood. And because it uses a dry blood spot it is also easy to post. My 2nd test took 10 days to be delivered using Royal Mail International Tracked (£6.90), then 6 days after that to receive the report.
