This is my favorite vitamin D to take. It’s easy to use and carry on when traveling. It comes in a small bottle and provided metered doses of 1000 iu’s of Vitamin D3 and 200 mcg of Vitamin K2. Taking it with food that contains fat is important for absorption so I take it with breakfast. I like that it’s liquid and has no taste or smell. I can drop it onto a spoon or put in a smoothie and I can’t taste it. Repeat bloodwork shows an increase in D levels so I know it’s working. While it’s a bit more expensive than other brands, it’s worth the money and I’ll continue to use this brand to help maintain my vitamin d level. Read more

I have been taking the natto stuff (mk7) but kept reading all the good stuff from Chris Masterjohn and Ray Peat about vitamin k2 in the mk4 version. Obviously not about to go ham on the goose liver - and pastured eggs and milk are good but not great sources of this vitamin. I can’t eat beef liver without gagging so this stuff is it. I take 1-2 drops a day usually in a divided dose. The bottle has 1200 drops in it so it should last a long time which is good cuz it’s expensive. I keep it in the fridge. I have noticed a difference I think - some people say mk4 doesn’t stay in your blood for very long and is useless while others say that it’s being absorbed by your tissues which is where you’d want this form to go. So ultimately I’m young and healthy and trying to stay that way with a nutritional amount of this stuff (not therapeutic doses) so I guess we’ll see how I’m doing in another 35 years? People say their teeth feel great, I’d agree. I was having some jaw pain and stuff that’s gone. I think I feel a little more energetic too. Update 12/13/19 Still taking this stuff and my original bottle is still good to go. I got a chest x ray done when I pulled a muscle to rule out any other issues and my bones are great. No arthritis and they’re nice and thick. I’m still pretty young but I know people younger than me that have been surprised to find out they already have the earliest stages of arthritis beginning. So anecdotally I think It’s helping keep me healthy and I’ll keep taking it in the low doses that I do. Read more

Vitamin D3 is fat soluble and the fact that this supplement already incorporates MCT oil (medium chain triglycerides) that are a high quality fat and not a rancid seed oil, makes it a very good quality product for proper absorption. Read more

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. Read more

This is a secret I’ve had for a long time in that this vitamin K 2. Will keep your arteries, clean of plaque. I don’t want you to believe me look up the research on it. It’s a fact that most people don’t know about it. I’ve been taking it for years and I’m 83 years old and in great shape. Read more

I’ve been buying this THORNE Vitamin D Liquid for my daughter, and it’s been an absolute lifesaver. She can’t tolerate vitamin D3 combined with K2, so finding this pure Vitamin D formula has been perfect for her. We actually buy K2 separately, so she can adjust her dose to exactly what she needs without any issues. The liquid form makes it super easy to give her the right amount, and the dropper is perfect for precise dosing. Since switching to this, her energy levels have been better, and I’ve noticed her immune system seems much stronger. What I really love is that I can control both her Vitamin D and K2 intake separately, which gives us a lot more flexibility and avoids any digestive discomfort she was having with other combined supplements. I’ve been buying this for her regularly now, and it’s working great. If you’re looking for a high-quality, pure Vitamin D supplement without K2, I highly recommend this one—it’s made a huge difference for her! Read more

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. Read more

I’ve received vitamin today and on the bottle the expiry date is 08/12/2022. Taking into account that the product is from USA market, USA date format mm/dd/yyyy so it was expired in August. Even if the date format is different, it’ll expiry in a month which is nonsense as how can I use the whole bottle in a month. I would like the product to be replaced with the normal expiry date.

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 Read more
