Brett K.Verified buyer“The first thing I noticed was how premium the bottle feels. It definitely doesn’t come across like a cheap supplement, and I really like that it comes in glass instead of plastic. The drops are super easy to use. I usually just add them to my smoothie. Would definitely recommend!”

Samuel G.Verified buyer“D3X has been a great addition to my morning routine—easy to use and tastes just like olive oil, which makes me feel good knowing it’s made with natural ingredients. Since I don’t get much sun exposure and my diet isn’t always ideal, this has been a huge help.”
Jason A.Verified buyer“I ordered D3X a few weeks ago. My favorite thing about it is how when I mix it in my shake you cannot tell it’s there. Super easy!”

Why D3X vs. regular vitamin D

Before you buy
Three questions
Every order includes a printed guide on how and when to take it.
Why vitamin D3 in olive oil?
Vitamin D is fat-soluble. Your body absorbs it along with fat, not water. In a Tufts study, peak vitamin D3 absorption was 32% higher when the dose was taken with a meal containing fat than with a fat-free meal.
So D3X comes already dissolved in organic olive oil, and there's fat in every dose, even with black coffee. We chose olive oil over the MCT, sunflower or safflower oil that's typical in D3 + K2 because it's a real food you already know. The amber glass bottle shields it from light.
Why olive oil, not MCT or seed oils →Liquid D3 + K2 drops or capsules?
We think drops, for three reasons:
- Absorption. In a head-to-head study of 70 adults, a vitamin D3 oral solution reached a higher peak and greater total absorption than the same dose as a capsule or a tablet.
- Fewer ingredients. Capsules need a shell, tablets need binders and flow agents, and gummies usually add sugar and leave out the fat. D3X is three ingredients: D3, K2 as MK-7, and olive oil.
- Nothing to swallow. Take it under your tongue or stir it into coffee, a shake or yogurt. It's unflavored.
How much D3 and K2 is in each dropper?
- 2,000 IU
- vitamin D3
- 100 mcg
- vitamin K2 as MK-7
- 1 mL
- one full dropper, once a day
One full dropper (1 mL) is one daily serving: 2,000 IU (50 mcg) of vitamin D3 as cholecalciferol and 100 mcg of vitamin K2 as MK-7. No counting drops. Each 30 mL bottle holds 30 servings, so one bottle is one month.
2,000 IU is below the 4,000 IU daily upper limit for adults set by the National Academies. Ask your doctor first if you're pregnant or nursing, already take vitamin D, or take medication, especially a blood thinner, since vitamin K affects how it works.

Love the science behind this product! I actually take it daily as a shot just straight in my mouth! No weird taste!
Much thought and care was put into creating this product. From the dark glass dropper bottle, to using organic olive oil with the D3 plus K2. Great product. Simple to add to coffe, or even take a dropper full by mouth. This product is quite simply, exactly what it needs to be! Excellent!!

The quality is excellent, it’s easy to take, and I feel more energized overall. I also appreciate that it combines D3 and K2 for better absorption and support. Highly recommended!
Love this D3 + K2 combo. The liquid form is easy to take and absorbs well, and I like that it’s in olive oil. It mixes in just about anything! Simple, clean ingredients and a great addition to my daily routine. Highly recommend!
Had me at 100% organic olive oil based. It is very refreshing to see a supplement company use natural ingredients
Easy to use, convenient dropper. Love that it's 3 simple ingredients!
D3X is the perfect liquid vitamin supplement! It’s a hassle sometimes to take so many pills that sometimes I forget to take them! With D3X it takes seconds to add into my morning protein shake! You can’t taste it at all and honestly it’s the best thing ever!!! Wish I had known about this liquid supplement sooner! Thank you D3X!!
I absolutely love the pure olive oil! It’s the only pure product I found online to order
I love it! The taste is like drinking pure extra virgin olive oil and NOW I know that my D3 level in my blood years will finally rise from 42 to
60-80 , a very healthy range. This elite company , D3X has done everything to give an extremely high quality product that absolutely will not be surpassed. I researched all of them and all of the top sellers never worked for me. You will love this product as I do! Also the black smooth box and the care in packaging the dark amber glass bottle is first class!
I love it! It’s a must for your health. Recommended!
Very good
I’ve been taking d3x liquid drops for about 4 months now. I like that they are in a smooth liquid form - much better than taking yet another Vitamin D supplement in pill form! Easy to swallow and good for supporting strong bones!
If you’re looking for a way to support your health, I have a vitamin D supplement I’d love to recommend to you. 😊
I’d been searching for a while for D3 and K2 in one product, without a plastic bottle. D3X checked both boxes. The label is short and clear. It arrived well packed in a glass bottle that looks nice on my counter. I’ve been taking a few drops every morning in my coffee for 6 weeks now. The coffee doesn’t taste any different and it’s the first supplement I’ve actually stuck with.
My energy doubled since taking D3X daily. Easy and convenient liquid formulation. Great product.
Great Product! Love the organic ingredients and it really helps me in office all day as I have a vitamin D deficiency! Highly reccomend!
Excellent product - great taste, packaging is of high quality, will buy again.
Unbelievable quality, the look of the bottle makes me excited to take my vitamin D in the morning. I like that they use olive oil to package it. I can put it under my tongue, on my morning eggs/toast, or in my morning beverage. Really happy with the product, highly recommend it
I love your product. My recent blood work showed significant improvement in D3, and I am thrilled! Thank you!!!!
Thank you for the clear and concise packaging explaining the benefits of incorporating this into my daily routine. The easy-to-use dropper paired with the smooth liquid makes it worthwhile. Glad to be a returning customer!
After I began using this product, I see improvements in running times, lifting strength, and clarity in my thinking and thought process!
10 stars for me refined daily ritual, transforms health and wellness into a genuinely delicious experience with its rich, buttery taste. Seamless blend of elegant simplicity and exceptional health performance.
I’ve really enjoyed using D3X! I notice a difference in my overall energy and mood when using it as a part of my daily routine. Highly recommend!
D3X has become a staple in my daily routine. I’m working on healing my immune system and I am pretty selective about supplements, so I appreciate the attention they put into the ingredients, sourcing, and formulation. The drops are easy to take and thoughtfully made, and an easy addition to my supplement regimen.
I’ve really enjoyed using D3X! The flavor is very mild, which makes it easy to incorporate into my routine in different ways. I’ve tried it straight from the dropper, in my coffee, and with breakfast, and my favorite has definitely been adding it to my eggs. The olive oil base pairs really naturally with them.
I also really like the simplicity of the product and how easy the liquid format is to use. It has been a great addition to my daily routine, and I’m looking forward to continuing to use it!
It’s 2 less pills I have to take which is great. And I think liquid is much more effective.
D3X sits right on my nightstand — it’s the first thing I take every morning, before anything else. Beyond the benefits of the vitamin itself, I really like the liquid dropper delivery. It’s clean, fast, and easy to work into a routine.
Love that I can put in my electrolytes every day!
