Most vitamin D products are capsules, softgels, or gummies — which means they have to survive your digestive system first. Over the next 60–90 minutes your stomach breaks them down, and much 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 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 75% more compared to 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.
Better absorption, better ingredients.
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.
99% of all Rejuvia orders arrive within 2–3 business days.
Yes. Rejuvia's D3+K2 spray is made with clean, all-natural ingredients — vegan, non-GMO, and made in a cGMP-compliant facility in the USA.
Every batch is triple lab-tested for purity and potency, with a Certificate of Analysis accessible via a QR code on the packaging. No artificial colors and no unnecessary fillers.
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 peppermint 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.
Used by 425,000+ customers
for daily immunity, bone strength and heart support.

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.
