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

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.

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.

Best supplement I've ever used. This product delivers all of the benefits Vitamin D supplementation is supposed to deliver, from energy levels to joint pain. I use 10 drops twice a day with food at breakfast and lunch. Life changing impact since I don't get a lot of sun. Takes a couple of hours to kick in. Gives me plenty of energy. I now understand how people get through the day without tons of caffeine. Very neutral taste.

Great product. Very good for mood and energy. Surprisingly very easy and good dropper. Super easy to dose by drop. I just tilt it to the side and it starts dropping a couple seconds later. It says do not refrigerate just keep it in a cool dry place. No taste or smell. Way better than generic or prescription.

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.

Love this supplement. Easy to use (and yes as others have mentioned - tip the bottle completed upside down and wait for drip to happen. It works very well). Have added this to my must-have supplement list.

High quality and easy to use, I take it at night with calcium to ensure proper absorption.

Does not really have a taste. Will update in a few months to see if this increased my vitamin D levels. I like this brand because it’s high quality. Research about taking vit D, you must take it with vit K for absorption.
