According to research, NMN acts quickly. Preclinical pharmacokinetic studies suggest that NMN is absorbed from the gut into the bloodstream within minutes and transported into tissues within 10 to 30 minutes [1, 2].

Then the magic — or rather, the biochemistry — begins.

The NMN is immediately used for NAD+ biosynthesis, helping replenish this essential molecule inside the body.

Research also suggests that this rapid uptake may be enabled by an NMN-specific transporter called “Slc12a8.”

Same Day: More Activity Inside Your Cells

Human studies show that NAD+ metabolites in blood plasma begin to rise within the first few hours after taking NMN — and continue increasing over time, suggesting greater NAD+ utilization in cells and tissues [4].

Your cells can already begin using these higher NAD+ levels to support hundreds of essential cellular processes.
And if you could talk to your cells, they’d probably thank you for it. :)

NAD+ Levels Keep Rising — Fueling the Powerhouses of Your Cells

As NAD+ levels continue to rise, they begin supporting the powerhouses of your cells — the mitochondria, where cellular energy is produced. 

A preclinical study found that treating human kidney cells with NMN for three days led to increased mitochondrial replication [5].

More mitochondria can enable more efficient energy production and metabolic regulation within the cell.

Day 30: NAD+ Levels Increase by Up to 40%

Here’s the fact: After just one month, NAD+ levels in the blood can be up to 40% higher than when you took your first capsules. With continued supplementation, these elevated levels can be maintained.

This is based on a human clinical study investigating NMN supplementation at a daily dose of 250 mg in healthy adults [7].

Can you feel the difference in your fitness yet?

Now we move from cells to entire systems, as aspects of your physical performance can begin to improve.

A human clinical study found that NAD+ is one of the most depleted metabolites in aging muscle and that higher NAD+ levels were associated with healthier muscle function [8].

Another clinical study showed that taking 250 mg of NMN daily for 6 weeks improved muscle strength and physical performance in healthy older men [19].

Your cells have more energy — and now your muscles can start to feel the difference.

How is your skin looking?

Advanced glycation end products (AGEs) are markers associated with skin aging. A clinical study in healthy postmenopausal women found that taking 300 mg of NMN daily for 8 weeks reduced AGE levels in the skin [10].

This reduction is considered a positive sign for skin aging and suggests that NMN may support healthier-looking skin over time.

Three months in — and you’ve already spent around 60 days with NAD+ levels up to 40% higher in your cells and tissues. But what has actually changed physically?

According to clinical studies, quite a lot.

In one study, healthy older men taking 250 mg of NMN per day showed improved walking speed [9].

Another study found that taking 300 mg of NMN daily doubled telomere length in peripheral blood mononuclear cells, which may indicate a younger biological age [12].

A lot can happen in six months — what has changed in your life?

With beLIVELY NMN, the benefits start to add up across your entire body. It supports multiple tissues and systems over time by targeting metabolic aging where it begins — inside your cells.

Have you ever thought about testing your biological age? After six months of taking NMN, it may come back significantly lower than before, because your cells have finally found the energy driver they needed — NMN!
