Why Support
NAD+ With NMN?
As we age, NAD levels in the body naturally decline. It has been reported in scientific literature that NAD+ levels decline significantly by age 55 — falling to around half of what they were in early adulthood.
NMN (Nicotinamide Mononucleotide) is a compound found in the body and is a direct precursor to NAD+. Researchers are actively studying NMN for its role in cellular energy metabolism and healthy ageing, with studies exploring its potential connection to mitochondrial function and cellular processes.
"Studies have explored NMN's potential connection to mitochondrial function, cellular vitality and the mechanisms of healthy ageing."
Any references to the relationship between NMN and NAD+ are made in the context of publicly available third-party studies, and we do not present these as authorised health claims under Regulation (EC) No 1924/2006.

Move the slider to see how cellular NAD⁺ availability is generally understood to change across the lifespan — and why a precursor strategy is studied.
Illustrative trend only. As NAD⁺ availability changes, the cellular processes it powers — energy metabolism, DNA repair signalling and sirtuin activity — are studied as part of healthy ageing research.
Our Founders Tested It.
The Results Spoke For Themselves.
Both co-founders committed to a before-and-after NAD+ test. Jonny for 1 month, Jack for 2. Both showed the same result.
★★★★★ Both co-founders, independently tested — same 2.3× result.
These results reflect Jonny Bradley's and/or Jack Woods' personal experience taking Element 5 NMN and were not obtained under clinical or laboratory-controlled conditions. Results are not typical and may vary. This is not medical advice. This product is not intended to diagnose, treat, cure, or prevent any disease. Always consult a healthcare professional before use.

"As a busy mum over 30 I was on a look out for something that actually works. My energy was always low and I was getting unwell ALOT! I've been taking element 5 NMN for over 6 months now and the energy I feel is amazing!"
"Been on Element 5 NMN for about 18 months now and honestly? It's been a game-changer for my training. Running and gym work just feel easier to recover from. I don't get that wiped-out feeling for days anymore."

Everything you want in a supplement Nothing you don't
Why NMN?
Five compelling reasons thousands of people are adding NMN to their daily routine.
Studied for its role in supporting cellular energy metabolism — fuel for your body at a cellular level.
A direct precursor to NAD+, essential for cellular metabolism and repair processes.
At work, in the gym, or on the go — your body relies on healthy cellular function every day.
As NAD+ levels naturally decline with age, NMN is being studied for its potential role in healthy cellular maintenance.
Support your daily routine without caffeine or quick fixes. Just clean, natural cellular support.

Everything you need to know about NMN, NAD+ and Element 5.
It's completely up to you — choose a time that fits your routine.
Many customers prefer to take NMN in the morning, but it can be taken at any time of day.
NMN can be taken with or without food; a glass of water is all you need.
Once ingested, NMN is absorbed into the bloodstream and transported into cells through a protein called SLC12A8. Inside the cell, it is converted into NAD+, a coenzyme involved in many biological processes.
This was described in a 2019 study published in Nature Metabolism by Dr. Shin-ichiro Imai's team, which suggested NMN can be taken up directly by cells without first converting to NR.
Research continues into how NMN uptake varies across tissues, particularly in the brain, muscles, and liver.
NMN doesn't typically produce fast or obvious effects and experiences can vary from person to person.
Some studies have explored changes in NAD+ levels after consistent use for 8 to 12 weeks. Some users track their progress using intracellular NAD+ tests, taken before and after supplementation.
The NAD+ molecule is too large to pass through cell membranes efficiently. NMN, being smaller and transported directly into cells, is a more effective precursor.
The recommended dose for Element 5 NMN is 500 mg per day (one capsule), taken in the morning with water.
Study Evidence: A study in Frontiers in Nutrition showed 250 mg of NMN nearly doubled NAD+ levels over 12 weeks. Another study observed significant NAD+ increases with 300–900 mg/day, with improvements in muscle endurance at higher doses.
NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme found in every living cell. It plays a key role in energy metabolism and important biological pathways like sirtuin activation.
Scientists continue to study NAD+ for its role in maintaining healthy cellular function, especially as levels are known to decline with age.
NR (Nicotinamide Riboside) is another NAD+ precursor that converts into NMN in the body before eventually forming NAD+.
NMN enters the NAD+ biosynthesis pathway at a later stage, meaning it may bypass one conversion step — making it a more direct precursor.
NAD+ is a coenzyme found in all living cells. It plays a central role in cellular energy metabolism and processes related to cellular maintenance and stress response.
Research is ongoing into how NAD+ interacts with proteins like sirtuins, studied for their role in healthy aging and cell regulation.
NMN is found in small amounts in edamame, broccoli, cabbage, avocados, and cucumbers — but the natural content is very low.
Edamame contains about 1.8mg of NMN per 100g. To reach a 500mg daily dose from food alone you'd need:
- 26.5kg of edamame
- 40kg of cucumber
- 80kg of avocado
- 55kg of cabbage
Yes! Open the capsule and pour into water. NMN may sink in small clumps initially (completely normal — it's compacted). Stir and it will turn slightly cloudy as it dissolves.
If left to settle, bubbles clear from the bottom up. NMN doesn't need to be fully dissolved to be effective — purely personal preference.
This is one of the most common questions we get — and we understand why. NMN is a precursor to NAD+, supporting NAD+ levels over time, not creating instant effects.
Everyone responds differently. Some feel a difference quickly; others don't feel anything — but that doesn't mean it's not working at a cellular level.
We suggest a more objective approach rather than going by feel:
- Take an NAD+ test before you start
- Re-test after 60–90 days
