42% Of Adults Are Low On The Hormone Their Body Makes From Sunlight
Vitamin D isn't really a vitamin, it's a hormone your skin makes from sunlight, and indoor life, sunscreen, and winter block it. We pair D3 with K2 so the calcium goes to your bones, not your arteries. 5000 IU D3 + 100mcg K2, one daily softgel.†
Daily vitamin D has been linked in randomized trials to roughly 13% lower cancer mortality.† An estimated 42% of adults are deficient without knowing it.
Description
JevityRx D3 + K2 delivers 5000 IU of vitamin D3 (the same form your skin makes from sunlight) paired with 100mcg of vitamin K2 as MK-7, in one small daily softgel.
Vitamin D behaves like a hormone: it regulates your immune system, your bones, your mood, and how your cells grow. But roughly 42% of adults are deficient, because modern life keeps us indoors, covered in sunscreen, and short on sun for half the year. K2 is the missing partner: it directs the calcium D3 helps you absorb into your bones, and away from your arteries.†
Why you need it
If you're tired in a way sleep doesn't fix, catch every cold that goes around, feel low through the darker months, or just haven't seen the sun in a while, there's a good chance your vitamin D is running low, and you'd never know without a blood test.†
Daily vitamin D has been studied for immune function, bone strength, mood, and, in randomized trials, an association with lower cancer mortality. Pairing it with K2 is what makes it a complete formula instead of half of one.†

You cannot feel a vitamin D deficiency. You can only feel what it costs you.
Vitamin D runs your immune system, your bones, and your mood. Studies have linked daily supplementation to lower cancer mortality, and roughly 42% of adults are deficient without ever knowing it.†
Two nutrients that only work when they're together.
D3 helps your body absorb calcium. K2 tells that calcium where to go. Take one without the other and you only get half the story.
The exact form your skin makes when sunlight hits it, and the form found in fatty fish and egg yolks. It behaves like a hormone, not a vitamin.
Indoor jobs, sunscreen, winter, age, and darker skin all cut how much you make. An estimated 42% of adults are deficient without knowing it.†
Vitamin D regulates immune cells, bone building, mood, and how cells grow. Daily levels have been associated in randomized trials with lower cancer mortality.†
Made by bacteria and found in fermented foods like natto and in grass-fed dairy, foods almost nobody in a Western diet eats regularly.
Western diets deliver very little K2, so most people taking D3 alone are missing the partner that makes it safe and complete.
K2 activates the proteins that pull calcium into your bones and keep it out of your arteries. D3 without K2 can send calcium to the wrong place.†
What customers say after 8-12 weeks.
What refilling the sunshine hormone supports.
From a stronger immune system to steadier mood, here's what vitamin D quietly runs.
Immune Defense†
Bone Strength†
Calcium to Bones (K2)†
Mood & Energy†
Real benefits. One daily softgel.
One hormone, the systems it runs, and what the research base says about each.
The mortality signal.
In a meta-analysis of randomized trials, daily vitamin D supplementation was associated with roughly 13% lower cancer mortality. The effect showed up with daily dosing, not big infrequent doses. It did not lower cancer incidence, so this is about association with outcomes, not prevention.†
Your first line of defense.
Vitamin D helps regulate the immune cells that respond to everyday threats, which is part of why deficiency tracks with more frequent illness, especially in winter when levels drop.†
Calcium, in the right place.
D3 helps you absorb calcium; K2 activates the proteins that steer it into bone and away from arterial walls. Together they support bone strength and cardiovascular health in a way D3 alone does not.†
Through the dark months.
Vitamin D receptors sit throughout the brain, and low levels are associated with low mood, especially in winter. Refilling the deficit supports a steadier baseline.†

Why this isn't the D3 you've tried.
Real dose. The right partner. Zero compromise.
A real 5000 IU dose
Not the 400-1000 IU in most multivitamins that barely moves your levels. 5000 IU is the amount that actually refills a deficit.
Paired with K2 (most skip it)
D3 without K2 sends calcium to your arteries as easily as your bones. We include 100mcg of K2 so it goes where it should.
MK-7, the best form of K2
We use MK-7, the longer-lasting, better-absorbed form of vitamin K2, not the cheaper MK-4 that clears in hours.
Clean & third-party tested
Non-GMO, free from gluten, dairy, and soy. Every batch third-party tested for purity and potency.
One softgel, daily
Daily dosing is what the research supports. One small softgel with a meal, no routine to overthink.
- 5000 IU D3 + 100mcg K2
- MK-7 form of K2
- Third-party tested
- Daily dosing
- Underdosed 400-1000 IU
- D3 alone, no K2
- Cheaper MK-4 (if any)
- No batch testing
JevityRx vs. Other Brands
- A real dose — 5000 IU D3, enough to refill a deficit, not a token amount.
- The K2 partner — 100mcg MK-7 so calcium goes to bones, not arteries.
- Clean & tested — no fillers, third-party tested every batch.
30 days. Feel the difference, or your money back.
Vitamin D refills a deficit over weeks, so give it time. If you're not completely satisfied in your first 30 days, contact us for a full refund, no questions asked, no return required.
Common questions.
Why do I need K2 with my vitamin D?
D3 tells your body to absorb more calcium, but it doesn't decide where that calcium goes. K2 activates the proteins that direct calcium into your bones and away from your arteries. Taking high-dose D3 without K2 can send calcium to the wrong place, which is why we pair them.†
Is 5000 IU too much?
5000 IU (125mcg) is a common daily maintenance dose for adults refilling a deficiency, and it's well within safe daily intake ranges. If you have kidney disease, take blood thinners, or are unsure of your levels, check with your physician, ideally with a vitamin D blood test.
When should I take it?
Take 1 softgel daily with a meal that has some fat, since vitamins D and K are fat-soluble and absorb better with food. Morning or evening both work, consistency matters more than timing.†
How long until I notice a difference?
Some people notice steadier energy and mood within a couple of weeks. Rebuilding blood levels takes longer, most people re-test after 8-12 weeks of daily use and see their numbers climbing back into range.†
Can I take it with magnesium?
Yes, and you should. Magnesium is required to convert vitamin D into its active form, so the two work together, which is why our Buy 3 bundle pairs D3+K2 with JevityRx Magnesium.†
What's your guarantee?
Every order is backed by a 30-day money-back guarantee. If you're not satisfied, contact us for a full refund, no questions asked.
They Felt the Shift. You Will Too.
Went from deficient to solidly in range on my last blood test. My doctor was genuinely impressed. Energy and mood came right up with it.*
Every year the dark months flatten me. Not this year. Steady energy, better mood, and I dodged the colds going around the office.*
I'd been taking plain D3 for years not realizing I needed K2 with it. This has both at real doses. Simple, and it just makes sense.*
