Best Liquid Vitamin D Supplements of 2025

"I'm deficient in vitamin D and also deal with acne, so the addition of vitamin K and omegas was a huge benefit for me. I tried the mocha flavor, which smells nice, but it tastes quite oily. Despite that, I prefer liquid supplements over pills for better absorption. I’ll keep updating on my progress, but so far, I feel this brand is quite high quality and I appreciate that it’s organic."

"I recently started using the Organic Vitamin D3 K2 Drops with MCT Oil Omega 3, and I'm thrilled with the results! The combination of Vitamin D3 and K2 is perfect for bone health and overall wellness. The 5000 IU dosage suits my needs well, providing a strong daily boost. These drops are easy to use, and I appreciate the convenient dropper. I've noticed a real improvement in my energy levels and mood, especially during winter. I highly recommend these drops for anyone looking to enhance their Vitamin D3 and K2 intake!"

"This liquid vitamin D by NOW is the best I've ever taken. It's clear and odorless, and mostly flavorless, though there's an oily base. I noticed an immediate boost in energy without any nausea."

"What a great product! I bought this for my daughter, who has a vitamin D deficiency, and we saw results within a week! Her energy level is up with no side effects. It's also very easy for her to take daily!"

"I had purchased this product before but stopped using it because I didn't notice any benefits. After learning that it needs to be taken with a meal, I've been feeling great and more energized."

"I had an issue with low vitamin D. My doctor suggested trying a liquid option for faster absorption. After using this product for about a year, my levels are normal again. The flavor is my favorite—subtle with a nice aftertaste. I love this product and will keep using it."

"I wasn't consistent with supplements until I needed to raise my vitamin D. I started with a level of 14 and after using this for several months, I'm now at 28. I've felt a difference, especially with energy and brain fog. I'm really happy with my results and appreciate the fair pricing. The taste isn't bad, but the texture is a bit oily. I get a hint of pineapple flavor and I absolutely love this supplement!"

"I constantly struggle with low vitamin D due to Hashimoto's and not having a gallbladder. This product makes it easy for me to remember to take my supplement.

"My blood work showed normal D3 levels, surprising my doctor. I feel better taking this product, and it's tasteless, making it easy to consume."

"I love the liquid format of this vitamin. Unlike other sweet options, this one has no flavor. It absorbs well, and I appreciate the inclusion of vitamin K."

"I prefer these drops over tablets because I can dissolve them in water. They have a subtle taste, and I often add a bit of orange or vanilla for extra flavor. No smell at all, and they are a good value for what you pay."

"After struggling with a severe Vitamin D deficiency and experiencing bone and muscle pain, I started using these liquid drops. After three months, my levels normalized, and the pain has significantly decreased. I really appreciate the ease of taking them, especially since I find pills difficult to swallow. I even add it to my iced coffee in the morning, and it blends perfectly!"

"My husband and I both like this Vitamin D product. He keeps a close eye on his levels, and this seems to help maintain them. However, I wish the dropper worked better; it often measures inaccurately and can get messy when trying to extract a full dose. Despite that, we enjoy mixing it into our morning beverages."

"I have dysphagia and can't swallow pills, so the liquid form of this vitamin supplement is a huge advantage for me. My vitamin D level improved from 12 to 28 in just 4 weeks. I can easily mix it with food or drinks, and it has no taste or aftertaste. It's been great for my energy and is very affordable!"

"My doctor recommended vitamin pills, but they weren't getting absorbed, and my vitamin D levels kept dropping. I decided to try this supplement with my doctor's approval, taking one dropper every other day. By day two, I felt significantly better, and within two weeks, my levels were improving. Initially, I masked the taste in a smoothie, but now I take it straight!"

"I purchased this liquid vitamin D supplement because I wanted an alternative to pills. However, it has a light unpleasant taste and feels oily. I've been taking it for about a month now, but I'm not seeing much difference, so I think I’ll switch back to pills."

"Vitamin D is one of the vitamins that most humans are deficient in, especially in the western hemisphere. I think around 80% of Americans lack Vitamin D. This supplement has been fantastic for a few reasons: it contains 600 doses in a bottle smaller than pocket-sized hand sanitizer, it's incredibly affordable, and the delivery mechanism is wonderful. I found that if you turn the bottle completely upside down, the drops come out perfectly. The liquid is tasteless and odorless, which means I can mix it with anything. I give my elderly mother and son 4-6 drops every 5 days, which is convenient!"

"Before taking this supplement, my blood work indicated I was extremely deficient in vitamin D. Other brands made me feel nauseous, but with these drops, I started with one drop a day, then moved to two, and now I take three drops daily. I've been consistent and take them with meals. My blood work now shows optimal levels, and I feel less tired throughout the day. It seemed too good to be true, but my results prove they're working wonderfully."

"I'm a fan of Thorne and was looking for a D3/K2 product. I find the measured drops to be simple and user-friendly. Sometimes you have to wait a bit for the drops to come out, but that’s no big deal for me. I take four drops every morning to reach the recommended dose. I've noticed an improvement in my mood and overall, I'm very pleased with the results of this product!"

"I chose Sandhu Vitamin D3 + K2 because I needed support for my bones and heart. The liquid drop format is fantastic; it's easy to take and doesn't require swallowing pills. I can mix it with juice or tea, and there's no unpleasant taste, which I appreciate. However, I haven't noticed much change in my well-being after a few weeks of use. Perhaps it needs more time to show results? Also, the dropper can be tricky for measuring the right amount, which makes me a bit concerned about taking too much or too little."

"So far, my experience with this product has been positive. I ordered based on the reviews, and I don't have any complaints at this point."

"I've been using these liquid, unflavored D3 and K2 drops and have noticed an overall improvement in how I feel. It's easy to administer—just drop it under my tongue—and there's no bad flavor to deal with. I can even mix it into drinks. The product is made in the USA from globally sourced ingredients and is third-party tested, which gives me peace of mind. I'm very satisfied with this choice."

"I noticed my Vitamin D levels increased quickly with this product. No flavor and it's easy to take. I will definitely recommend it!"

"I love that this product has no smell or taste; it's just pure Vitamin D. However, since I'm pregnant, taking 10 drops can be a bit tedious sometimes."

"I switched from capsules to drops, and now just 2 drops in my coffee keeps my Vitamin D levels stable. No taste and it saves money—definitely a win!"

"I find it easy to take with the dropper, and the mild taste is a bonus. Compared to other brands, I feel the price is reasonable!"

"This liquid Vitamin D3 is perfect for me after my gastric bypass surgery. It's essential for my health, and it fits the bill."

"I appreciate that it has no taste and is clear and easy to swallow. However, I wish the quantity was larger—I'd probably order two next time!"
