Optimize Vitaminz Liquid Vitamin D3 K2 Drops with Dandelion Root & Bilberry | Immune, Liver & Bone Support, MK-7 Formula, Fast Absorption Liquid Multivitamin, 30 Day Supply, 2 Fl Oz

I’ve been using these Optimize Vitaminz liquid drops for a bit now, and overall I’d say they’re a pretty solid option if you prefer liquids over pills. The biggest plus for me is how easy they are to take. The dropper makes it simple to measure, and I like that I can just add it to a drink or take it without dealing with swallowing capsules. The taste is actually decent too—slightly citrusy and not overly “vitamin-like,” which makes it easier to stick with daily. I also appreciate that it combines D3 and K2 in one formula, along with extras like dandelion root and bilberry. It feels a little more thought-out than a basic supplement, and the dark glass bottle is a nice touch for keeping everything stable. That said, it’s not perfect. The bottle only lasts about a month, which makes it feel like you go through it pretty quickly. I also noticed the formula is a bit of an odd mix—some things are included in good amounts, while others you might expect in a multivitamin aren’t there, so it may not fully replace other supplements. Overall, it’s convenient, tastes fine, and seems well-made, just with a couple trade-offs that kept it from being a full 5 stars.

I didn't know this until after I bought this - but it's super important to take vitamin D3 WITH vitamin K2 so that it shuttles calcium to your bones instead of your arteries. Optimize Vitaminz has both together - so I threw out my vitamin D3 Flavor is great, it's kind of like a blood orange/citric-y type flavor. way easier to take vs. pills too - so that's nice. All in all I love it!

I have never used liquid vitamins before this, so it was hard to compare with anything. I probably would not purchase this product again, as in my opinion, pills are easier to take than these drops. Some people mentioned that the dropper is hard to fill to the correct line, and I found this to be the case. A syringe would be much easier for dosing, and the manufacturer might consider including a syringe and just having a regular cap instead of a dropper cap. I think that the taste is ok, but not super nice. For me, the citrus flavor was good, but not enough to overpower the medicinal undertones, which are strong. I did not notice increased energy over the time I took the supplement, though I already take other supplements and there may be little difference between the capsules I usually take and these. Overall, I would stick with capsules myself.

Some of the things I like about this supplement: I like that it is a liquid, so I don’t need to swallow yet another pill. I like the formulation. I like the dark bottle. I like that it is made in the USA. Some of the things I do not like: It separates pretty quickly when mixed with water. I don’t like the color; it looks like rusty water. I really, really don’t like the taste. To me, it just tastes like a vitamin pill has been ground up and mixed with a liquid. I don’t like that I can only get .8ml into the dropper. It makes dispensing a 2ml dose more difficult. I usually end up taking whatever I can squeeze out of two droppers. I think it is expensive and not a good value for me. Overall, I think this is a good product. If I prioritized not needing to swallow a pill versus the higher expense, this could be a great solution. For me, the taste is unpleasant, like a vitamin partially dissolved in my mouth, so I’m deducting a star.

I have recently began taking Optimize Vitaminz Liquid Vitamin D3 K2 drops and thus far have been impressed. I really like that it is in a liquid format. I’ve taken capsules before, but this absorbs much faster and feels more effective. The dropper makes dosing simple and precise, and I like that I can add it to water or take it directly without any hassle. It also has an added blend of dandelion root and bilberry. It does not have any off-putting odor. It’s not just another basic D3 supplement. Instead, it is more like a well-rounded formula that supports not only immune health but also liver function and overall wellness. The taste is mild and not overly sweet or artificial, which I appreciate. Some liquid vitamins can be hard to tolerate, but this one is actually quite pleasant. I also like that it uses the MK-7 form of Vitamin K2, which I’ve read is more bioavailable and works synergistically with D3 for bone and cardiovascular health. Overall, this feels like a thoughtfully formulated, high-quality supplement. If you’re looking for an easy-to-take vitamin D3 + K2 with added herbal benefits, this is definitely worth trying.

I’ve tried quite a few liquid supplements over the years, and this one has some solid pros with a few things to be aware of. First off, I really appreciate that it comes in a dark glass bottle. That’s always a plus for preserving the integrity of light-sensitive vitamins and keeping the formula stable longer. The dropper is also marked, which makes it much easier to measure out a serving compared to unmarked droppers. The bottle contains 30 servings, which is pretty standard for liquid vitamins, but it does feel a bit underwhelming—especially if you’re taking it daily, it goes quickly. As for the formula itself, it seems well thought out overall. One thing I do think is worth mentioning (and something to be mindful of) is that some vitamins are fat-soluble—like vitamins A, D, E, and K. These can build up in the body if taken in excess, unlike water-soluble vitamins that are more easily excreted. That said, most reputable supplements are formulated to stay within safe daily ranges when used as directed. The main caution here is really about consistency and dosing accuracy—since droppers aren’t always perfectly precise, it’s just something to be aware of rather than a dealbreaker. Taste-wise, this one is actually pretty pleasant. The lemon flavor is definitely the dominant note—very tangy and reminiscent of something like Tang. I personally appreciate that because it does a great job of masking the typical “vitamin” taste that a lot of liquid supplements have. Overall, this is a good option if you prefer liquid vitamins and want something that’s easy to take and tastes decent. Just be mindful to stick to the recommended serving size, especially with fat-soluble vitamins in the mix.

I’m really impressed with these Optimize Vitaminz Liquid D3 K2 Drops. The combination of Vitamin D3, MK‑7 K2, dandelion root, and bilberry makes this feel like more than just a basic vitamin — it’s a well‑rounded formula that supports immunity, liver health, and bone strength all at once. The liquid absorbs quickly, and I genuinely feel the difference in my energy and overall wellness. The taste is mild and easy to take, and I love that one bottle lasts a full 30 days. After using it consistently, I’ve noticed better mood balance, less sluggishness, and a general sense of feeling “lighter” and more supported. It’s become part of my daily routine. If you’re looking for a high‑quality D3/K2 supplement with extra herbal benefits, this one is absolutely worth it. Highly recommended!

I was initially excited to purchase this product, as none of the listed ingredients appeared to contain anything I’m allergic to. However, upon receiving the item, I discovered that it contains sunflower lecithin—an ingredient not shown in the product images or disclosed in the ingredient list at the time of purchase. Unfortunately, I’m allergic to all sunflower-derived ingredients, so I’m unable to use it. I strongly encourage the manufacturer to update the ingredient listing to accurately reflect all contents for the safety of individuals with allergies.
