Product Description

Nano C is a breakthrough form of Vitamin C, designed for optimal absorption.

The Vitamin C particles in Nano C have been ‘chopped up’ using the latest nanotechnology. So they are 100x smaller than the openings in your gut lining.

That’s why your body can absorb Nano C better than many other sources of Vitamin C. [3]

The Nano C in each batch is rigorously tested for purity and to ensure against toxins and contaminants. And the FDA regularly audits our manufacturing facility for safety and purity.

Based on ingredient research, and real customer experiences, here’s what you can expect when you start taking Nano C:

  • null

    Promotes a rapid immune-cell response to viruses and bacteria – Targeting contagious pathogens in as little as 30 minutes! [6]

  • null

    It helps protect your friends and family by lowering your risk of passing anything to them[5] …

  • null

    You’ll gain more confidence in your financial security when you’re taking fewer sick days off work [2]...

  • null

    Be able to care for your partner when they’re feeling sick, without being concerned about getting sick yourself [2]

  • null

    The freedom to go out and enjoy yourself, no matter the time of year, safe in the knowledge that your immune system is stronger than ever [2]

  • null

    And not having to worry so much about a sickness ruining your vacation or family event you were looking forward to [2]


Are You One Of The Four Out Five Americans Running Low On Vitamin C?

You’ve likely heard how Vitamin C can:

  • Supercharge your immune system [2]
  • Help you recover from colds and other viruses quicker [5]
  • And even help you avoid catching respiratory infections in the first place[7] [8]

Harvard Medical School reports that Vitamin C is an essential fuel for your immune system [9]

And 2-time Nobel Prize-winning scientist, Linus Pauling swore by it…

But despite Americans consuming more Vitamin C than any other time in history [10]

77% of Americans suffer from LESS than optimal levels of Vitamin C. [11] And a further 31% are running dangerously-low on this vital immune fuel. [12]

How is this possible?

It’s because the Vitamin C in food, fruit drinks, and ordinary supplements is too big to pass through your gut lining immediately. The average Vitamin C particle is 10,000 nanometers wide. Whereas the openings in your gut lining are only 100 nanometers wide. [13] [14]

It’s like trying to fit a 5ft-beach ball through a garden hose. So the Vitamin C your consuming isn’t being fully absorbed. And your immune system isn’t getting the Vitamin C it needs to function at full capacity. [5]

That’s why Zenith Labs teamed up with the world’s leading Nano Engineers. And we created a form of Vitamin C that CAN fit through your gut lining. [1]

Introducing Nano C

Nano C is created using the latest nanotechnology. The Vitamin C particles in Nano C are 100x smaller than the openings in your gut lining. [15] This helps your body to absorb Nano C quickly-and-easily into your bloodstream. [3] [16] Helping it to reach and fuel your immune cells that need it most. [1]

Frequently asked questions


Nano C only contains natural Vitamin C – that’s broken down into nanosized particles. This helps the Nano C absorb into your bloodstream quicker and easier, helping it get to your immune cells, which need Vitamin C for fuel.

Take a look at the Supplement Facts below.


Our unique nano form of Vitamin C is rigorously tested for purity and to ensure against toxins and contaminants. Our manufacturing facility is regularly audited by the FDA for safety and purity.

We also focus on primarily using natural ingredients. Ingredients which your body already knows how to use. And which gently, naturally support your health.


There’s no such thing as “overdosing” on Vitamin C.

If you take a high dose of a regular Vitamin C supplement, the particles can stay in your gut without getting absorbed. This can cause gas or other gut discomforts until your body flushes them out.

But Nano C avoids that problem since the particles are so small that they’re quickly absorbed and put to use. Not only is Nano C perfectly safe. But it also avoids the gut discomfort risk of other Vitamin C supplements.


Take one full dropper of the Nano C under your tongue each morning. It’s that simple. Each bottle comes with enough Nano C for a 30-day supply.


Through my years of medical practice, I’ve seen first-hand that individuals react differently to the same treatments. While the ingredients inside Nano C can benefit everyone who takes them, it remains the fact that results can vary. If you’re not happy with Nano C for any reason, even if the bottles are empty, simply contact us for a complete refund. In most cases, we won’t even ask you to send back the bottles.

The reason you should get started right now:

There’s no reason to go another day worrying about viruses and bacteria wreaking havoc on your health. Take care of your immune health today. Nano C is the only way to get Vitamin C small enough to pass through your gut wall easily. Helping to rapidly fuel & support your immune system.
