THORNE - Vitamin D + K2 Liquid with a Metered Dispenser - Vitamins D3 & K2 to Support Healthy Bones & Muscles* - 1 Fl Oz (30 ml) - 600 Servings

This vitamin D + K2 liquid is easy to use and feels like a very high-quality supplement. The metered dispenser makes it simple to get an accurate dose without guessing, which is a big plus. The liquid form absorbs well and can be taken on its own or added to food or drinks. The combination of D3 and K2 supports bone health, immune function, and proper calcium utilization in the body. It doesn’t have much taste, which makes it easy to take daily. The bottle also lasts a long time since only a few drops are needed. It is a little more expensive than basic vitamin D options, but the quality and absorption make it worth it.

THORNE's Vitamin D + K2 Liquid has been exactly what I needed for optimal bone and cardiovascular health support! As someone who has struggled with vitamin D deficiency despite taking various supplements, this liquid formula with the synergistic K2 combination has finally delivered the results my doctor and I were looking for. The liquid format with the metered dispenser is incredibly convenient and ensures precise dosing every time. Just a few drops under the tongue and I'm getting the perfect amount of both D3 and K2 without having to swallow large capsules. The absorption seems superior to the tablets I used previously - my most recent blood work showed significant improvement in my vitamin D levels after just three months of consistent use. What I love about THORNE is their unwavering commitment to purity and quality. These vitamins are free from unnecessary additives, artificial colors, and preservatives that are common in other brands. As someone with multiple food sensitivities, knowing that THORNE products undergo rigorous testing gives me complete confidence in their safety and potency. The combination of D3 and K2 is brilliant because they work synergistically to support both bone health and proper calcium utilization. Since starting this supplement, I feel more confident that I'm not only getting adequate vitamin D but also ensuring the calcium I consume goes where it should - into my bones rather than soft tissues. The liquid has a very mild taste and mixes easily into water or juice if preferred, though I find taking it directly is just as pleasant. The bottle lasts several months with daily use, making it excellent value for pharmaceutical-grade supplementation. My energy levels have noticeably improved, and I feel more resilient during the darker winter months when natural vitamin D production is limited. My healthcare provider was impressed with my improved levels and recommended I continue with this specific formulation. For anyone serious about optimizing their vitamin D status with a trusted, scientifically-formulated product, THORNE delivers uncompromising quality and effectiveness.

These little drops are micro powerhouses that are rapidly absorbed and so easy to take. I have been using the drops on a spoon and just taking them that way. The taste is basically nothing, but I also follow with water and do a swish to make sure I get all of it. I have been a long time user of Thorne products and am really happy with this D3/K2. The quality is excellent, but I don't expect anything else from this brand. I am waiting to see if my levels come up, but I take this supplement three times a day, so I believe there is some benefit. I have seen a lot of people write about the issues with the dispensing but it works as designed. Tip the bottle at a 45 degree angle and let it drip out. Shaking it will only frustrate you and make a mess. It takes a second for the liquid to go through the dispenser so you just have to be patient. Overall, the quality is so high and if you have problems swallowing pills, this is a great alternative.

I’ve tried several Vitamin D + K2 supplements over the years, but this one by Thorne truly stands out for its quality, potency, and convenience. First off, I appreciate Thorne’s reputation for third-party testing and clean ingredients. As someone who is cautious about what goes into our bodies—especially for our kids—knowing there are no unnecessary additives or allergens gives me great peace of mind. We have two teen athletes in the house, and supporting their immune systems, energy, recovery, and bone health is a top priority. Their coaches emphasize the importance of D3, and this has been a perfect, reliable option to include in their daily routine. Within just a few weeks, we noticed improvements in their mood, focus, and overall recovery between practices and tournaments. The liquid dropper format is a game changer. It’s super easy to dose, especially for picky kids or anyone who struggles with swallowing pills. The taste is neutral enough to take directly, or we can mix it into a smoothie or juice without any complaints. I also love that it combines D3 with K2, which is important for proper calcium absorption and bone support—critical for growing, active teens. Storage is simple—I keep it in a cool, dark cabinet (not the fridge), and it holds potency well over time. This is now a staple in our family’s supplement routine, and I’ll definitely continue to reorder. If you’re looking for a reliable, well-formulated Vitamin D + K2 supplement for your household, I can’t recommend this one enough.

Most economical we have found for everyday vitamin D supplement. Definitely works because my vitamin D levels are higher than last time i got my blood tested. I also don’t always remember to take it every day. Good stuff.

I bought Thorne Vitamin D + K2 because it came highly recommended, Thorne is a dependable brand. The liquid form makes it easier to consume, the only issue is delivery. The “dispenser” is the same as essential oil bottles delivery system which means although it is a precise measurement, it is very slow in delivery. You have to wait and watch it drip out into the beverage every time which is fine if you have the time. It’s hard to know if it works, but that’s where the trust factor comes in. Only buy from trusted sources that can validate their product. Thorne s one

Quality Ingredients. Promotes energy & sleep

The vitamin D itself tastes like nothing at all, but you have to get it out of the bottle first. The "dispenser" is ridiculously hard to shake anything out of it. I want to be able to just tilt my head back and shake the drops in, but most of the time they never come out. I have tried shaking them onto a spoon, but that is also hit or miss. The best thing is to shake vigorously onto food or a cup of liquid. This should be a dropper instead of an essential oil-like dispenser. If I can find one to switch it out with, I have no idea how much that drop would equal these tiny drops, so I don't really know how much I would be taking. As it is, I still don't really know, because the drops come out so randomly, and maybe 2 come out at once, I really don't know. I'd love to give this 5 stars, but the dispenser makes it impossible to. A 1 for the dispenser, and a 5 for the drops themselves.

So easy to use , long lasting and value for money

I use it daily, great product.

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! 4.9/5

Easy to consume, convenient way to get enough vitamin d. Just the D & K vitamins, no nasty additives that normally upset my digestive tract. Drop into my water twice a day. Simple. I think they are working. Seem pricey, but, the quantity justifies this.
