Energy Depletion After 40
NAD+ levels drop by up to 50% as we age. Your mitochondria — the power plants of every cell — run low on fuel, leaving you fatigued, slow to recover, and struggling to keep pace with your younger self.

The Problem
Your Energy Has Been Quietly Running Out Since 40
NAD+ — the molecule your cells use for energy, repair and survival — declines by up to 50% between your 40s and 60s. The fatigue, brain fog and slow recovery you feel? That is cellular energy depletion happening in real time.
Brain Fog & Lost Focus
NAD+ is critical for neuronal health and cognitive energy. When levels fall, mental clarity, memory and concentration all suffer — the fog thickens and sharp thinking feels further away every year.
Slower Metabolism & Vitality
Cellular repair slows with age. NAD+ activates sirtuins — the longevity proteins governing DNA repair, metabolism, and cellular survival. Without sufficient NAD+, everything in your body slows down.
The NAD+ Difference
The Molecule That Powers Every Cell in Your Body
In research laboratories worldwide, NAD+ is now called the most important molecule in ageing biology. Essential for energy production, DNA repair and cellular vitality — WaferiX® delivers it sublingually for maximum impact.
⚡
Cellular Energy Production
NAD+ is the essential co-enzyme that powers your mitochondria. Restoring NAD+ levels gives your cells the fuel they need to produce energy efficiently — reducing fatigue and improving stamina from the inside out.

DNA Repair & Healthy Ageing
NAD+ activates sirtuins — the longevity proteins governing DNA repair, inflammation and cellular survival. Higher NAD+ means faster repair, slower cellular ageing and better resilience as you get older.

THE PRODUCT
WaferiX SL-NAD+
Sublingual Supplement
30 highly bioavailable NAD+ wafers — engineered for fast sublingual absorption and daily cellular support.
100mg NAD+ per wafer — the research-backed dose, delivered as highly bioavailable nanoparticles for rapid cellular uptake.
Patented WaferiX® Fast Acting Technology — peel, place under tongue, let dissolve. No water. No capsules. No fuss.
30 sublingual wafers — a full month supply. Take 1–2 daily, or as recommended by your physician.
Always refrigerated — keep wafers potent, fresh and effective throughout the month. Protect from light and moisture.
Simple Daily Routine
How to Take Your SL-NAD+ Wafer
Quick and effective intake — no water needed. Just one wafer placed under the tongue. Peel, place, dissolve, done.
1
Peel Tab — Don't Pop
Always peel back the blister tab carefully. Never push the wafer through the foil — this protects the delicate sublingual wafer and ensures it reaches you intact.
2
Place Under Tongue
Rinse your mouth first, then place the wafer under your tongue. Position it as far back as comfortable for the best sublingual absorption surface area.
3
Let Dissolve Fully
Allow the wafer to dissolve completely under your tongue. Do not consume food or drink within 5–10 minutes of taking for maximum NAD+ uptake.
4
Never Chew or Swallow
Never chew or swallow the wafer whole. This bypasses the sublingual absorption that makes WaferiX® so effective. Let the nano technology do the work.

Your Questions, Answered
What is NAD+ and why does it matter after 40?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell and essential for energy production, DNA repair and cellular health. Research shows NAD+ levels decline by up to 50% between your 40s and 60s — contributing to fatigue, brain fog, slower metabolism and the visible signs of ageing. Replenishing NAD+ with SL-NAD+ supports cellular energy, vitality and healthy ageing at the most fundamental level.
What is WaferiX® sublingual technology?
WaferiX® is a patented sublingual delivery system. The wafer rapidly dissolves under the tongue, releasing highly bioavailable NAD+ nanoparticles directly into the bloodstream — bypassing the digestive system entirely. This nano absorption technology is covered by patents listed at www.ixbiopharma.com/patents and delivers NAD+ faster and more efficiently than standard capsules or oral supplements.
How do I take SL-NAD+ correctly?
Rinse your mouth, then peel back the blister tab carefully — never push the wafer through the foil. Place the wafer under your tongue and allow it to dissolve fully for as long as possible. Do not chew or swallow the wafer. Do not consume food or drink within 5–10 minutes of taking. Take 1–2 wafers daily, or as recommended by your physician.
How long before I notice results?
Many users report improvements in energy levels and mental clarity within 2–4 weeks of consistent daily use. Deeper cellular benefits — improved metabolism and vitality — typically build over 4–8 weeks. Individual results vary depending on starting NAD+ levels, lifestyle, age and consistency. Taking SL-NAD+ daily as directed gives your cells the best opportunity to restore and maintain optimal NAD+ levels.
Does SL-NAD+ need to be refrigerated?
Yes. SL-NAD+ wafers must always be kept refrigerated prior to use. Protect from light and moisture. Ensure the carton is sealed when not in use. Following storage instructions preserves the potency and bioavailability of the NAD+ nanoparticles throughout the product's shelf life. Only remove a wafer immediately before use.
Is SL-NAD+ suitable for everyone?
Do not take SL-NAD+ if you are pregnant, breastfeeding or trying to conceive. Not suitable for persons under 18 years of age. If symptoms persist or you have any existing medical conditions, please consult your physician prior to use. The product contains sugars and lactose. Vitamin and mineral supplements should not replace a balanced and varied diet and healthy lifestyle.
