I can tell the difference
I prefer micellized vitamins because my body doesn’t seem to break down more complex forms of vitamins. I have Vitamin D deficiency (genetic causes, in my case) and I’ve tried other forms of Vitamin D, even drops, and my body hasn’t absorbed them well at all. Or the ones with soy lecithin have caused me a lot of pain, because that’s what soy lecithin does to my body.Then, I found this form of the vitamin. My body seems to absorb this Vitamin D more easily and so I’ve continued to use it for nearly half a year now. One dose is one drop. In my case, I’ve found that if I take fewer than 4 drops a day, I go back to having some Vitamin D deficiency symptoms, but I don’t want to overdo it either, so I take between 1-4 drops a day and see how I feel in a few days.I also like the taste. It’s mild and sweet and slightly citrusy.

Great taste, amazing absorption
Great taste, amazing absorption. So many people run low in vitamin D and have no idea how significantly it affects their health. This affordable, high quality formula is just perfect. Vitamin D deficiency can actually cause depression, hair loss, aching joints, obesity, digestive issues, bowel inflammation and many other maladies. The exceptional absorption and easy use of this high-quality product are wonderful. I was in NO WAY COMPENSATED or purchase discounted for this review.

Increases Vit. D levels with no side effects
I cannot say enough great things about Klaire Labs Micellized Vit. D3 Liquid – 400IU! As one with multiple food-sensitivities who has great difficulty taking most supplements, I searched two years for a Vit. D3 supplement I could take without negative side effects. Finally, I found the perfect solution with this product. No side effects and it is very effective. My Vit. D blood level in August was on the low side at 29. After taking this product 5 drops per dose, two doses per day (4000 IU per day) as recommended by my doctor, my Vit. D blood level in December is now 48. Yea! Thanks to Klaire Labs for such a great product!

Low dose, very tolerable
I’m sensitive to side effects from most vitamin d supplements. I’m able to take these without feeling like my brain is vibrating.I believe lower dose over time is much better than one big dose weekly, which is often what drs prescribe.And the fact that since the dosage is ONE DROP, not only is it easy to take, you can customize your dose easily without using up the entire bottle in a short time.Klaire labs is my go-to for quality, bioavailability , and the least side effects.

Great vitamin D for kiddos!
This is great vitamin D for kiddos. My baby who is now 20 months old loves it and happily takes it. It also lasts a long time! We are still using the bottle we got last year. I trust this brand as I have been happy with their probiotics too and prefer it to other big kid product brands.

Excellent and purely developed form of Vitamin D
I have been using this MICELLIZED form of Vitamin D for years. It was recommended to me by two different nutritionists. I always feel better and can tell this form is working when I take it.
