Why Rejuvia Works
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 works to break 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.
How To Use
Spray 6-8 times under your tongue or on the inside of your cheek once daily.
Ingredients
Key Ingredients: Vitamin D3, Vitamin K2 (as K2Vital®), Purified Water, Organic Cane Sugar, Organic Peppermint Flavor

Review return and refund information
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®. Taking D3 without K2 means you're only getting half the picture.
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 than pills. The benefits of maintaining healthy vitamin D levels build with consistent daily use.
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, depending on your dosage. Each spray tube contains 240 total spritzes and our suggested dosage is 6–8 spritzes under your tongue per day.

Your indoor life is costing you vitamin D
Most people spend 90% of their day behind walls and glass that block the UV rays your skin needs to produce vitamin D.
But replacing D3 alone isn't enough — without K2, your body absorbs the calcium but has nowhere to put it.
This sublingual spray gives you the D3 you need and the K2 that makes sure it actually works.
- Vitamins D3 + K2 paired together
- Plant-based D3 supports calcium absorption
- K2 directs calcium into bones and teeth
- Replaces what your body can't make

Most people are deficient without knowing it — and low D3 is directly linked to poor sleep quality. This bioavailable form supports your body's natural melatonin production and helps regulate the sleep-wake cycle at a hormonal level.
Vitamin K2
The most bioavailable form of K2, sourced from Vita-K2® — the gold standard used in clinical research. Works in the background while you sleep to support cardiovascular and bone health during your body's nightly repair cycle.

Frequently Asked Questions
What does the D3 + K2 spray do?
It's our daily foundation spray. Vitamin D3 supports strong bones, healthy immune function, muscle function, and overall energy and mood — and K2 makes sure the calcium your body absorbs actually gets directed where you want it. Most people don't get anywhere near enough D from sunlight alone, especially in the winter or if you spend your days indoors, so this is the one you take every morning without thinking about it.
Why are D3 and K2 together instead of separate?
Because they only really work as a pair. D3's job is to help your body absorb calcium — but on its own, it doesn't tell that calcium where to go. K2 is what directs it into your bones and teeth, where it belongs, instead of letting it settle in your soft tissue and arteries. Taking high-dose D3 without K2 is a very common mistake. We formulated them together so you don't have to think about it.
How and when do I take it?
Spray it under your tongue in the morning, hold for a few seconds, then swallow. Once a day, every day — consistency is what makes fat-soluble vitamins work. It's mild-tasting, so you can take it straight or right after your coffee.
What's in it — is it clean?
Just the actives and a clean, all-natural base. Made in the USA in a cGMP-compliant facility, triple lab tested, vegan, and non-GMO, with no artificial colors or unnecessary fillers. It's the same standard we hold every Rejuvia product to.
Why a spray instead of a capsule or gummy?
A capsule or gummy has to be swallowed and digested before any of it reaches your bloodstream — that takes 45–60 minutes and you lose potency in the process. An oral spray absorbs directly under your tongue, straight into your bloodstream, bypassing the stomach entirely. Better absorption, faster, and no giant horse pill to choke down. That last part matters more than people admit — a lot of our customers came to us specifically because they can't or won't swallow pills.
Are Rejuvia's sprays third-party tested?
All of our products are indepdently triple lab-tested for purity and potency each batch. Each prodcut comes with a Certificate of Analysis to ensure we are using the finest ingredients and you can access it via a QR code on the packaging. We batch-test and validate with certified third-party labs to ensure purity and consistency.
What is Rejuvia's return policy?
Return receipt and refund handling have not yet been arranged for this store. Please review return and refund information before placing an order.
