I was buying NMN and resveratrol separately from two brands. Having both at full dose — 500mg at 98% — with a proper CoA makes the whole thing simpler.

Full dose printed clearly, batch number on the base, and the team sent the CoA the same day. That level of transparency is the reason I reordered.

A realistic timeline for what you’ll notice.
NMN works at a cellular level over weeks of consistent use — it is not a stimulant. Below is what customers commonly report, and when. Individual results vary; these are customer-reported experiences, not guaranteed outcomes.
Days 1–7
Nothing dramatic — and that’s expected
NMN is not a stimulant. Most customers report no noticeable change in the first week. The process is biochemical, not immediate.
Weeks 2–4
Early, individual changes
The most commonly reported early observations relate to daily energy consistency. Reports vary widely between people.
Weeks 5–10
The window most trials study
The strongest published evidence comes from studies of 12 weeks or longer. Our 60-day guarantee is built to cover a realistic trial period.
Month 3+
Consistency is the point
As with any food supplement, daily, consistent use is recommended. NMN supports the NAD+ pool over time rather than acutely.
Two molecules. Full-dose transparency.
No fillers hiding the dose. No proprietary blends. Every milligram printed on the label.
Within the published range
Human research on NMN has used doses from 250mg to 1,200mg daily. Our 500mg beta-NMN dose (>99% purity) sits in the middle of that evidence base.
Advanced delayed-release capsules
Delayed-release capsules are designed to protect the formula from being released immediately after swallowing, allowing the capsule to open later in the digestive process. This can help provide a more controlled delivery experience and is one of the reasons we use delayed-release HPMC capsules rather than a standard capsule shell. It’s a small detail, but one that reflects ELIXER’s focus on formulation quality from the ingredients right through to how they’re delivered.
A food supplement, not a medicine
NMN and resveratrol have no authorised UK/EU health claims. We make no medicinal or disease claims, and compete on dose, purity, form and third-party testing.

What is NMN?
NMN (Nicotinamide Mononucleotide) is a naturally occurring compound found in trace amounts in foods including broccoli, avocado, cabbage and edamame. Biologically, it is a direct precursor to NAD+, a coenzyme present in every living cell.

My energy has increased, my face looks more youthful, i've been told i look rejuvenated and I just turned 50 so I am feeling blessed to feel so well, thank you Elixer MMN!
Pleased I found these vitamins. They have increased my energy levels and my sleep has very much improved. Would highly recommend.
After taking for two weeks I had so much energy my hair and skin improved no more brain fog from next month going to up the dose
Excellent service and they really do work, I have ankoylosing spondylitis and it helped with the fatgeaue and my hair stopped going grey ! I mean I don't mind grey hair but I just noticed that it stopped. Can't recommend these guys enough. When I can afford it I will be back
I definitely feel more alert and with much more energy. I had been suffering with low mood swings and lack of energy after an illness. Since taking NMN I can feel that lifting and having so much more confidence has given me a real boost
