My son was delayed in bring born early. Dud some research found that vitamin d helps with development issues. ALL PRAISES TO THE MOST HIGH HE IS IMPROVING NOT EVEN A FULL TWO WEEKS. He starting to speak, legs straighten and just improving in therapy. His therapist gets really excited to see him improve..WORKED

I was very happy to find this on amazon, my child’s first bottle was bought Online at a store that most towns have but this was quickest and less stressful way to order it again. Hoping this bottle will give us the same great results, on my child’s lab work to monitor vitamin d deficiency. It has helped keep it where it should be with two drops a day (some days we forget but that’s okay) and my child doesn’t complain about the taste, just sometimes gets inpatient, when it takes long to drop. I found a way to speed up the drop, by opening it up, while upside down. 😅 ((no one paid me for this review, this is our life, real life))

It is extremely difficult to get the liquid out of the little nozzle thing at the top. I often have to forcefully jerk the bottle 3-4 times with the bottle upside down to get anything to come out. This makes me nervous regarding accurate dosing, as we all know it is not safe to give too much to a child. Also, what constitutes "1 drop?" Each drop that comes out varies in size due to the way it struggles out of the bottle. This would be much better if it came with a dropper. I don't care about the gimmicky "1 drop" thing. Just keep it flavorless and give us an easier way to get it out of the bottle. Sheesh. I can't speak to the effectiveness either. I will know when we recheck my child's D levels in a few months.

Easy to use and lasts a long time! This is actually less expensive than the cheap brands because it lasts so much longer than those and it isn't filled with extra stuff!

These are the best vitamin d drops! They are tasteless and 1 tiny drop is the dose vs. the nasty poly-vi-sol pediatricians usually recommend.

BUYER BEWARE!!! Please check product labeling to ensure you are receiving the correct item! This is super dangerous- label across the front of the package is the kids drops 400iu and the bottle is for adults 2000iu. Carlson makes great products, but always double check especially for kids!!
