5 out of 5 stars
Noticeable difference
Started taking this after finishing my basic Vit D capsules. The liquid is so much easier to take, has zero flavor/taste, and paired with the K2 offers optimal absorption. Thorne is a trusted brand and I've been a user of their products for many years. I take 4 drops once in the morning to make a 2000 IU dose (recommended by my PCP due to chronic low Vit D levels) instead of taking two drops twice daily. I've had no issues. I have noticed an improvement in my general mood and I'm very happy with the results. I call them my happy drops

    I love the fact that the supplement is metered. Do not listen to the other reviews who evidently are so busy they don’t have a few seconds to wait for this wonderful d3 k2 to meter out. I recently bought a different d2 k3 from a superstore, only because I was out and saw it there. What a mistake!!! This different brand has a dropper but is absolutely horrible taste wise. Do yourself a favor. Stick with Thorne. No taste. Easy to use. Wonderful benefits. I have bought Thorne vitamin d3 k2 many times in the past. Perfect every time.

    4.0 out of 5 stars High quality vitamin but the dropper is very annoying.
    Reviewed in the United States on January 17, 2025
    Verified Purchase
    These are high quality vitamins and supplement a very important vitamin that many people are deficient in. Also with the small dose the value is actually quite excellent. I've noticed improvements to my mood, anxiety issues, joints, and overall health since taking them. I just wish the bottle was maybe a squeeze bottle somehow. It's a hard bottle and the dropper lid just doesn't work well to dispense the vitamin oil. I have to tilt my head all the way back and it just feels like it takes forever to get a few drops out. The drops are very small so if you're not very deliberate to make sure they fall onto your tongue or back of your mouth you might not even be sure they dispensed. If they are able to develop a better dosage method these would be perfect.

    5.0 out of 5 stars Absolutely Amazing Vitamin D supplement!
    Reviewed in the United States on December 6, 2024
    Verified Purchase
    Vitamin D is the one the vitamins that MOST humans , especially in the western hemisphere, are deficient in. I think something like 80% of Americans are Vitamin D deficient.

    This supplement is great for a bunch of reasons.
    1) TONS of doses in one tiny bottle. 600+ doses in a bottle smaller than pocket-sized hand sanitizer.
    2) EXTREMELY affordable - considering you get 600 doses.
    3) The delivery mechanism is WONDERFUL. I was worried because some reviews said the drops didn't come out easily. They must have had a defective bottle, or weren't turning the bottle completely upside down. It works perfectly.

    Make sure you turn the bottle COMPLETELY upside down. Then let 1-2 drops come out. The liquid is tasteless, odorless - so you can put it whatever you want.

    Protip: Vitamin D is fat soluble, unlike Vitamin C.....so you can just a larger dose a few times a week.....or you can take it daily, since it builds up!
    This is great because I give my elderly mother and my son doses from this bottle.....and I don't have to do it every single day like I do for myself. I just give them about 4-6 drops every 5 days or so.

    Reviewed in the United States on December 3, 2024

    Short version:
    No side effects, blood work showed optimal vitamin d levels when previously deficient after taking three drops a day.

    Long version:
    Before I started taking this supplement, my blood work showed that I was extremely deficient in vitamin D. Other brands of pills made me nauseous and gave me very bad headaches. I’m also diabetic so all the sugar free gummies I tried upset my stomach. I took these as a Hail Mary and started with one drop a day for a week. I proceeded to two drops, and now I take three drops a day. I’m very consistent and take them every day with a meal and my other prescription pills. My blood work now shows optimal levels, and I’m nowhere near overdose or high levels. I will continue to monitor but so far I’m just sitting in a good range. I was worried because the drops are so small and taste like nothing, that nothing was really happening internally, I also wasn’t experiencing any negative side effects and it seemed too good to be true, but bloodwork proves they’re working wonderfully. I feel less tired throughout the day and my dark circles around my eyes seemed to have lightened a little bit.

    Reviewed in the United Arab Emirates on January 18, 2025
    Verified Purchase
    This Vitamin D + K2 liquid is a powerhouse in a bottle! It’s super easy to take, thanks to the metered dispenser that gives you exactly what you need—no guesswork, no mess. The liquid format absorbs quickly, and with 600 servings in one bottle, it feels like it’ll last forever (okay, maybe not forever, but close!).

    I’ve been using it daily, and I’ve noticed my energy levels are better, and my muscles feel less fatigued after workouts. Knowing it’s supporting my bones too is a nice bonus—healthy bones, happy life, right?

    The flavor is very mild, almost nonexistent, which is great if you’re not a fan of overly flavored supplements. Just pop it into your favorite drink or take it straight—it’s that simple.

    The only downside is the price—it’s a bit of an investment upfront, but considering how long it lasts, it’s totally worth it. Also, it’s important to take it with a fat-containing meal for proper absorption, but that’s standard for vitamin D.

    Overall, this is a high-quality, easy-to-use supplement that delivers real results. If you’re serious about supporting your bones, muscles, and overall health, this is a no-brainer!
