Say goodbye to constant fatigue and hello to more energy

The Cell Life dietary supplement can help your body feel more energetic and balanced.

Do you often feel tired
and lacking in energy?

Maybe it's because of the "power plants" in
your cells—the mitochondria.

That's because they're responsible for the body's own energy production. As you get older, however, it becomes harder for your body to produce enough energy.

Cell Life can support your body's natural energy production. Many users report that it makes them feel more energetic and fit.

Our Customers' Positive Experiences

“I’ve had trouble falling asleep and staying asleep my whole life. After a week of taking Cell Life (1 capsule in the morning, 1 in the evening), I sleep like a log and wake up feeling noticeably more refreshed—without waking up at 3 a.m.—and like I’m 20 years younger. During the day, I have more energy, my mind stays clear, and I’m finally sleeping better again—Swiss quality that works calmly and reliably for me.”

“At the office, I was especially annoyed by my irritability and the 3 p.m. afternoon slump, especially after 4 p.m. After two weeks with Cell Life, I’m much more relaxed, my focus stays steady until the end of the workday, and I need less coffee. It feels like steady energy throughout the day—no jitters, no crashes, just staying focused from start to finish.”

I take Cell Life before and after my workout. Results after just a short time: no midday slump, I cut my coffee intake from 4 to 2 cups, and I was able to lift significantly more weight than usual on the leg press—plus, I recovered faster the next day. Exactly what I was looking for: better recovery, a clear head during coaching sessions, and consistent energy well into the evening.

Working rotating shifts left me constantly tired. After about 10 days of taking Cell Life, I’m able to sleep through the night more often again, I feel noticeably more refreshed in the morning, and I can stay focused in the afternoon without that post-lunch slump. For my shift work, this steady energy is worth its weight in gold, and the fact that it’s a Swiss product gives me confidence.

Lots of deadlines, lots of responsibility, and used to mean lots of coffee, too. After two weeks on Cell Life, I’m calmer in the team; my mind stays clear until the end of the workday, and 4→2 cups of coffee are enough—no jitters, no crash. For me, it’s steady energy instead of quick bursts; exactly what I need in my day-to-day life.

Do you often feel tired? Low energy? Trouble sleeping?

You wake up in the morning and feel as if you've barely slept.

Your energy starts to wane as early as mid-morning, and by noon at the latest, that familiar slump sets in: You’re unfocused, listless, and somehow constantly tired.

Exercise doesn't really help you relax either. 

Instead of feeling refreshed, you often feel even more exhausted afterward—almost burned out.

And then there are those minor but persistent complaints: 

Back pain, sore knees, tense shoulders.

That’s just how it is when you get older, isn’t it? No, it doesn’t have to be that way.

Why many people (as they age)
feel less and less energetic

Let’s take a closer look at what happens in our bodies as we get older:

Our cells contain tiny “power plants”—the mitochondria. They produce the energy our bodies need for important functions such as movement and healing. This energy is supplied in the form of ATP (adenosine triphosphate).

But to produce ATP, our bodies need a molecule called NAD. If there isn’t enough NAD, less ATP is produced—and you’ll lack energy.

The problem: As you get older, your body produces less NAD. This can disrupt the natural processes in your cells. Many people then report lower energy levels, slower recovery, or general fatigue.

So, should I just take NAD? Not necessarily. If you take NAD directly, it may not end up where it's needed at that moment.

But here’s the thing: Your body can produce NAD on its own—and use it exactly where it’s needed. Provided, of course, that it gets the right building blocks to do so. And that’s exactly where Cell Life comes in.

Cell Life by Fastesana: Help Your Body Produce Energy

In medicine, many products are developed to treat specific symptoms, such as medications for pain or muscle tension. At Fastesana, however, we have created a product that works preventively and supports the body before symptoms arise.

That's how Cell Life came to be: Cell Life contains nicotinamide riboside (NR)—the building blocks your body needs to produce NAD on its own.

Studies show that taking 1,000 mg of NR daily doubled NAD levels after just 3 weeks.

Many users report that after a few weeks of using Cell Life, they feel fitter and more energetic.

Who is Cell Life suitable for?

Cell Life is for anyone who wants to be more than just “awake”: It supports mental clarity, restful sleep, recovery, and an active metabolism—especially if you:

You want to fall asleep more easily at night and wake up feeling refreshed in the morning.

want to counteract age-related processes, regenerate faster, and support natural cell repair.

You want to fall asleep more easily at night and wake up feeling refreshed in the morning.

Have trouble recovering after exercising or on strenuous days.

want to improve your performance, mental clarity, and memory.

want to counteract age-related processes, regenerate faster, and support natural cell repair.

In our daily work with patients, we are often asked the same question: “What vitamins or dietary supplements should I take?”

But honestly—the answer isn’t simple. The market offers many products, but unfortunately, they don’t always provide the help we need. Often, the dosages are too low and the prices are way too high. As doctors and certified nutrition therapists, we wanted to recommend something to our patients that we could stand behind 100 percent. But what we were looking for simply didn’t exist. So we decided to take matters into our own hands. And that’s how Cell Life came to be. A product we developed with passion and based on our own experience.

Frequently Asked Questions About the"
" Cell Life Dietary Supplementfrom Fastesana

What is Cell Life?

Cell Life is a high-dose dietary supplement that helps support your body’s natural energy production. It contains nicotinamide riboside (NR), the building blocks your body uses to produce NAD on its own when it needs it. This can help you feel more energetic.

How does Cell Life work?

Cell Life contains NR—a precursor to NAD. NAD is a molecule that plays a role in cellular energy metabolism. Regular use can support the body’s natural energy-producing processes. Many people report feeling more energetic as a result.

What is NAD, and why is it important?

NAD (nicotinamide adenine dinucleotide) is a molecule responsible for energy production in our cells. It plays a key role in many important bodily processes. As we age, NAD levels decline, which can lead to fatigue and reduced performance. Cell Life helps your body compensate for age-related changes in NAD levels.

How soon can I expect to see results?

Cell Life has long-term effects. Studies show that taking 1,000 mg of NR daily can double NAD levels in as little as 3 weeks. How quickly you notice results can vary from person to person, but many users report having more energy and better recovery after a few weeks of use.

Is Cell Life right for me?

Cell Life is suitable for anyone who wants to boost their energy and feel more vibrant. It can be especially helpful for people who are often tired, have trouble recovering after exercise, want to improve their concentration and performance, or want to counteract the natural aging process.

How long should I take Cell Life?

Cell Life is designed for long-term use to provide ongoing support for your body’s natural energy production. You can take Cell Life for as long as you want to maintain your energy and vitality.

Where is Cell Life manufactured?

Cell Life is manufactured in Switzerland. We place great emphasis on the highest quality and production under strict quality controls.

Where can I buy Cell Life?

You can easily order Cell Life directly from our website. The product will be delivered to your home in just a few days.

What is NMN, and how is it different from Cell Life?

NMN (nicotinamide mononucleotide) is a compound often associated with anti-aging and increasing NAD levels. However, in the EU and Switzerland, NMN is not approved as a dietary supplement and may not be offered for human consumption.
Cell Life deliberately relies on nicotinamide riboside (NR), an approved NAD precursor that is authorized in the EU.

Advantages of NR:

Approved in the EU: NR is officially approved for human consumption.
Improved bioavailability: NR is absorbed more efficiently than other B3 compounds.
Direct NAD precursor: NR directly contributes to increasing NAD levels.
