Go Beyond Your Vitamin D deficiency

Your free weekly dose of practical, science-based tools & tips to optimize your energy.

Hello Trailblazers,

Before we dive in...
This issue was meant to land in your inbox Thursday, but life threw a few unexpected curveballs — both technical and personal. Thank you for your patience and grace. The good news? Some delays are just opportunities for upgrades. And today’s issue, the final chapter of our light trilogy, might just be the most illuminating yet. So Here we go!

Over the last two issues, we introduced you to the forgotten nutrient of modern life: sunlight.

In Issue #1: We explored how each of your cells is like a little car battery that holds a charge of about -70 millivolts, and the precise timing (10 AM–2 PM) and UVB wavelengths (280–315 nm) your body needs to synthesize Vitamin D — and how missing that window can lead to widespread deficiency.

And in Issue #2: We zoomed in deeper, revealing how light charges your mitochondria—the power centers of your 30+ trillion cells.

Now, it’s time to complete the trilogy. We’ll zoom in on the actual unit of sunlight energy — the photon. This isn’t spiritual poetry. This is physics and biology.

Every second, each square centimeter of your skin receives up to 10²¹ photons — a billion trillion packets of light energy.

They don’t just warm you…They program you!

Today’s Fix – Under the Sun:

  • What Are Photons?

  • Sunlight: The Original Cellular Nutrient

  • Sunlight vs. Sunscreen as a Filter

  • And more!

🔬 What Are Photons?

Photons are the smallest packets of light energy. Though massless, they’re biologically potent, and they carry instructions. Every sunrise, trillions of them flood the Earth, delivering pure biological data that tells your body how to wake up, regulate, and repair.

When they hit your skin or eyes, they trigger specific chemical and electrical responses.

Spectrum Breakdown:

  • 🔴 Red Light (620–750 nm):
    Penetrates 8–10 mm deep. Boosts ATP by up to 200% by activating cytochrome c oxidase (Hamblin, 2017).

  • 🌈 Infrared (750–1000+ nm):
    Penetrates even deeper. Supports blood flow, detox, and inflammation reduction.

  • 🔵 UVB (280–315 nm):
    Converts cholesterol into Vitamin D3 via 7-dehydrocholesterol.
    Just 15–30 min of sunlight can yield 10,000–25,000 IU of Vitamin D (Holick, 2004).

    But modern life blocks the signal:

We live indoors. We wear sunglasses. We coat our skin with chemical sunscreens

As a result, your body experiences:

  • 🧠 Circadian rhythm disruption

  • 😞 Mood instability and fatigue

  • 🔋 Low mitochondrial output

  • 💤 Sleep and hormone irregularities

🧬 How Photons Power Your Biology

Your body is wired to read and respond to sunlight.

  • 👁 Eyes:
    Over 100,000 photoreceptors each, syncing your brain clock to the sun.

  • 🧬 Skin:
    Chromophores absorb light, boost mitochondrial function, and regulate circadian biology.

  • 🩸 Blood:
    Red light is absorbed by hemoglobin, enhancing oxygen delivery and circulation.

💡 Wang et al. (2016) found that red/infrared light can reverse mitochondrial dysfunction, restoring cellular power.

Diagnostic Spotlight: How we measure the problem.

If you’re tired all the time…

If your brain feels foggy by 2 PM…

If your mood, metabolism, or immunity feels “off”...

It may be your lifestyle. It might be about how much light you’re exposed to, and the type of light. We live in a world flooded with information, stimulation, and static — but disconnected from natural light.

The Data:

  • 🔒 90% of our time is spent indoors (EPA, 2022)

  • 💊 90% of Americans are Vitamin D deficient or insufficient (CDC, 2018)

  • Mitochondrial dysfunction is now linked to chronic fatigue, depression, autoimmune diseases, heart disease, and even neurodegeneration (Wallace, 2012)

Your body runs on voltage. And light is the switch. It’s not that you’re broken — you’re underlit:

  • 🌫 Morning grogginess (even after 7–8 hours of sleep)

  • 🧠 Brain fog or attention dips midday

  • 😞 Mood swings, irritability, or low resilience

  • 🦠 Frequent colds, sluggish immunity

  • 🧬 Low Vitamin D levels (< 30 ng/mL)

Let this diagnostic moment be your wake-up call. It’s time to plug back into the power source we were designed for.
🧠 Why Light Is Your First Nutrient

Before breakfast.
Before coffee.
Before supplements...

There was light.

Photons:

  • Enter the body faster than food

  • Direct gene expression

  • Regulate your hormone clock

  • Power your cells with ATP

Your body doesn’t need more interference. It needs more light.

Fix-It Shift:

Old belief: Sunlight is dangerous and should be blocked.
Fix-It Shift: Sunlight is your original programming language — your body can’t run without it. We’ve been conditioned to see sunlight as a threat — something to fear, avoid, or shield ourselves from.

But here’s the truth:
Your body doesn’t just tolerate light. It requires it.

Photons are not “nice to have.”
They are biological instructions — light-coded software that tells your cells how to function, heal, and stay alive.

This is where everything changes.

When you start thinking of sunlight as a nutrient — as data, not danger — you begin to live differently:

  • You wake with the sun

  • You seek natural light exposure in the early morning and evening

  • You allow your skin and eyes to receive that full-spectrum code

This is beyond Vitamin D deficiency. It’s about electrical potential.
It’s about restoring your body’s ability to:

  • Charge your cells

  • Coordinate hormone signals

  • Set your circadian clock

  • Activate immune responses

  • Synthesize ATP (your body’s energy currency)

Let your body receive the full signal. Sunlight isn’t just heat — it’s data, fuel, and frequency. It’s the original recipe for human vitality.

Fix-it Action:

1. Morning Light (within 30–60 min of sunrise)

  • No sunglasses or glass barriers

  • 10–15 minutes outside

  • Stack with movement + water

2. Midday Sun Dose (10 AM–2 PM)

  • 10–30 minutes of direct skin exposure

  • No sunscreen (use shade or time management)

  • Supports Vitamin D synthesis

3. Sunset Reset

  • Watch the sun go down

  • Boosts melatonin and sleep prep

What Blocks Your Charge?

Let’s get controversial.

What if the sunscreen you apply to “protect” your skin is actually filtering out the very light that powers your cells? What if the light that’s most damaging to your biology… doesn’t even come from the sun? We’ll talk a lot about Red Light vs. Blue Light, but for now we’ll just give you give you a quick introduction.

Let’s unpack it.

🔴 Red Light vs. 🔵 Blue Light — Not All Light Is Created Equal

Nature’s light comes in a spectrum — and your body treats each wavelength differently.

Red and Near-Infrared Light (600–900 nm):

  • Penetrates deep into the skin (up to 10 mm)

  • Stimulates mitochondrial enzymes like cytochrome c oxidase

  • Boosts ATP (cellular energy) by up to 200% (Hamblin, 2017)

  • Reduces inflammation, enhances blood flow, and speeds up tissue repair

Blue Light (400–495 nm):

  • Found in natural sunlight but also over-amplified in screens and LEDs

  • Shown to suppress melatonin production at night

  • Can induce oxidative stress and premature aging in skin when overexposed (especially without the balancing effects of red/infrared light)

🌞 Sunlight: The Original Cellular Nutrient

We tend to think of nutrients as things we eat or drink — but light is arguably your first and most foundational nutrient. Your cells absorb photons like roots absorb water. They convert it into:

  • ATP for energy

  • Nitric oxide for vascular flow

  • Melatonin (when received through the eyes at appropriate times) for hormone signaling

  • Vitamin D3, via UVB photons, to regulate over 1,000 genes

Without sunlight, this nutrient supply dries up — and so does your cellular voltage.

⚠️ Sunscreen: A Pharmaceutical Filter?

Chemical sunscreens are designed to block UV rays, but they don’t stop there:

  • They also reduce exposure to red and near-infrared light — the healing bands.

  • Active ingredients like oxybenzone, avobenzone, and octinoxate can create free radicals under sun exposure.

  • Many of these chemicals are endocrine disruptors, mimicking or interfering with your hormones.

Imagine applying a skin cream that:

  • Disrupts your hormones

  • Filters out your most therapeutic light

  • And then tells your cells to “protect themselves” from the nutrient they evolved under

That’s not protection. That’s interference.

🔋 What Enhances or Blocks Your Charge?

Your cells hold a natural voltage — around -70 millivolts when healthy. That negative charge is critical for:

  • Nutrient transport

  • Waste elimination

  • Internal communication

  • Resistance to inflammation

⚡ Things that block your charge:

  • 24/7 indoor living

  • Sunglasses during sunrise/sunset

  • Chemical sunscreens

  • Chronic dehydration

⚡ Things that enhance your charge:

  • Morning sunlight (red + infrared-rich)

  • Midday UVB (Vitamin D synthesis)

  • Sunset light (melatonin priming)

Next Thursday we’ll provide you with a list of Mineral-based sunscreens, if you must use them. In the table below we’re showing you the main difference:
