Most vitamin D comes as a capsule, softgel, or gummy — which means it has to survive your digestive system first. Over the next 60–90 minutes your stomach breaks it down, and a good portion of the vitamin is lost before it ever reaches your bloodstream. Vitamin D is fat-soluble, too, so how much you actually absorb from a pill can vary a lot from person to person.
Rejuvia is a sublingual spray. You spray it under your tongue, where the vitamins absorb directly into your bloodstream — no digestion, no waiting, no waste. Your body takes in up to 90% more than gummies and pills, so far more of the D3 and K2 on the label becomes the D3 and K2 your body actually gets to use.
Same vitamins — far better delivery.
Rejuvia is 100% made in the USA and ships from the USA. All orders ship within one business day from our warehouse in Chicago. We offer free shipping on all orders over $59.

Vitamin D3 and K2 are a team, and they work best together.
D3 is what lets your body absorb calcium from your food. But absorbing calcium is only half the job — on its own, that calcium can end up in the wrong places, like your arteries and soft tissue, instead of your bones.
That's where K2 comes in. K2 activates the proteins that direct calcium into your bones and teeth and keep it out of your arteries. Take D3 by itself and you raise calcium absorption without telling your body where to put it. Pair it with K2 and the whole system works the way it's meant to.
That's why every Rejuvia spray combines 2,000 IU (50 mcg) of D3 with 120 mcg of clinically-studied K2VITAL® — the two nutrients that make each other work.
Two actives in a clean base: Vitamin D3 (2,000 IU / 50 mcg) and Vitamin K2 as clinically-studied K2VITAL® (120 mcg), in a base of purified water, organic cane sugar, and organic peppermint flavor.
D3 and K2 work as a team — D3 helps your body absorb calcium, and K2 directs that calcium into your bones and away from your arteries.
Why D3 and K2 together?
They work as a team. Vitamin D3 helps your body absorb calcium, and K2 helps direct that calcium into your bones and away from your arteries — which is why we pair 2,000 IU (50 mcg) of D3 with 120 mcg of bioactive K2VITAL®.
How is this better than a D3 pill?
Most vitamin D comes as a capsule or softgel that has to survive digestion, where a good portion is broken down before it's ever absorbed. Our spray goes under your tongue and absorbs directly, so your body gets what it needs faster and more efficiently.
Can I take it every day?
Yes — it's made for daily use. A few sprays each morning is all it takes, and it's non-habit-forming with no dependency or tolerance buildup.
What flavor is it?
A light, pleasant natural mint taste that most customers genuinely enjoy.
How long does one bottle last?
Roughly one month of daily use. Each spray tube contains 240 total spritzes and our suggested dosage is 6–8 spritzes per day.

Here's Why D3 And K2 Belong Together
Here's Why D3 And K2 Belong Together
D3 helps your body absorb calcium from your food. K2 helps your body use that calcium, by activating the proteins that bind it into your bones. One gets the calcium in. The other helps put it to work. That's why every daily serving pairs:
- 2,000 IU (50 mcg) of Vitamin D3
- 120 mcg of Vitamin K2 as K2VITAL®

Started For My Mom, Now For Everyone
My mom was 55, going through menopause, and struggling — she'd tried everything and nothing helped. So at the University of Pennsylvania I built her first oral spray with natural ingredients that absorb under your tongue and work in minutes, not hours.
That obsession with better absorption is why every Rejuvia spray — including our D3+K2 — is sublingual. Five years later, it's the daily ritual for over 425,000 people, and it all started with my mom.
