The Sun. In A Bottle.
Most people walking around today are low in vitamin D. They don’t know it. Their doctors don’t mention it. But their bodies feel it.
See Why It Matters ↓Hey, it’s Dr. Martin here…
Let me tell you something simple.
Most people walking around today are low in vitamin D.
They don’t know it. Their doctors don’t mention it. But their bodies feel it.
I saw it for over 45 years in our clinic.
And here’s what I know…
When your vitamin D levels are down, everything in your body is down.
So we decided to fix that.
You Can’t Bottle The Sun
But you can bottle what the sun does for your body. Here’s the truth most people never hear.
- 1Your ageYou make 4 times less vitamin D from the sun at age 70 than you did at 20.
- 2Where you live your lifeYou spend over 90% of your life indoors.
- 3SunscreenSunscreen blocks your ability to make vitamin D.
- 4Fall and winterAnd fall and winter wipe out whatever levels you built over the summer.
That’s why flu season hits when vitamin D drops.
That’s why memory, mood, immunity, bones, and heart health change so fast.
It’s not bad luck. It’s low vitamin D.
Most Vitamin D Supplements Are Useless
Here’s what most companies won’t tell you.
- 1They use vitamin D2, not D3.D2 barely raises blood levels.
- 2They give you tiny doses.Like 400 to 1,000 IU. That does almost nothing.
- 3Or worse, they leave out vitamin K2.And without K2, all that calcium vitamin D pulls in can get stuck in your blood vessels. That hardens arteries. That leads to heart problems. That ages you faster.
You don’t want that. You want the calcium in your bones, not your bloodstream.
That’s why K2 matters.
Why D3 + K2 Together Matters
This is the part almost nobody explains.
Vitamin D is the bouncer. It lets calcium into your bloodstream.
Vitamin K2 is the traffic cop. It makes sure calcium goes to your bones, not your arteries.
This is why vitamin D and K belong together.Always.
A study in the European Heart Journal found Vitamin K2 cut heart attack and all-cause death risk in high-risk patients.
Vitamin D alone boosts calcium. But K2 tells it where to go.You need both.
One dropper is 5,000 IU of Vitamin D3 and 100mcg of Vitamin K2. That’s it.

Questions About This Formula
Real questions from real patients. Straight answers.
Why do I even need vitamin D?
Because your body doesn’t work right without it. Every cell in your body has a vitamin D receptor.
Your immune system, your brain, your bones, your hormones. They all depend on it.
Low vitamin D is a check-engine light. When levels drop, something is off. And most people are low.
Dr. Martin on this
Can’t I just get vitamin D from the sun?
You can. But most people don’t.
We live indoors. We cover up. We wear sunscreen. And once you hit 60, you make a fraction of the vitamin D you did at 20.
Fall and winter? You make almost none. That’s why supplementing is simple common sense.
Dr. Martin on this
Why is K2 included?
Vitamin D pulls calcium into your bloodstream. But you don’t want calcium floating around in your arteries.
K2 (MK-7) takes that calcium and puts it where it belongs—your bones.
I call vitamin D the “bouncer” and K2 the “traffic cop.” You need both.
Dr. Martin on this
Why MK-7 instead of other forms of K2?
MK-7 stays in your system longer. It absorbs better. Your bones and blood vessels prefer it.
It’s the form used in the strongest heart and bone studies. We use MK-7 because it works best.
Dr. Martin on this
Why a liquid vitamin D instead of capsules?
Absorption. Plain and simple.
Liquid gets into your system faster and more predictably. Plus, it’s concentrated, tasteless, and easy to take.
One dropper on your tongue, in a smoothie or in water, and you’re done.
How much should I take?
Most people do well with 4,000 to 5,000 IU daily.
But here’s my real advice. Get your levels checked once or twice a year.
Your sweet spot is 60 to 100 ng/mL. That’s where immune strength, heart health, and brain protection are at their best.
Dr. Martin on this
Is it safe?
Vitamin D is one of the safest nutrients on the planet. Your immune system needs it. Your bones need it. Your brain needs it.
We’re not talking megadoses here. We’re talking about getting you into the normal human range, the levels people used to get naturally from sun and outdoor living.
This is about restoring what life has taken away.
Dr. Martin on this
What will I notice?
Most people notice three things. More steady energy. Better sleep. Stronger immune response.
For others, it’s less brain fog, better mood, fewer aches, clearer thinking.
When your vitamin D rises, your whole body works better. It’s that simple.
★★★★★“It is the best I have found, to give me my energy back and my immune system is so much stronger because of it.”Bonny Nelson
Dr. Martin on this
Why this formula over others?
Because we made it the way your body needs it.
D3, not D2. Strong, not weak. MK-7, not the cheap forms. Liquid, not poorly absorbed capsules. With K2, not alone.
Every part of it is built for one goal. To raise your vitamin D to where it should be.
Dr. Martin on this
Your body runs on vitamin D.
The question is…
Are you giving it enough?
Most people aren’t. And when vitamin D drops, everything else drops with it.
You don’t want to live like that. You don’t have to live like that.
