Natural Factors, Vitamin D3 400 IU, Supports Strong Bones, Teeth and Immune Function, 100 tablets (100 servings)

This is the best of the best! My kids are super picky and this is their favorite! Small, tastes great, doesn’t get gross. ⭐️⭐️⭐️⭐️⭐️

I have to say, these are exactly what I was looking for. I take a multivitamin but needed just a little more Vitamin D (I'm an adult woman) but didn't want too much. I know these are chewable but I didn't care; they taste very good by the way so kids will like them. Now I can get the right amount of Vitamin D.

I've been using these vitamins as a D3 supplement for my two kids (ages 6 and 2). They are a small chew-able tablet and my kids love the taste. A D3 supplement is very important, especially in the winter months when we aren't getting natural D3 from the sun. I've been very happy with these for my kids!

I bought a bottle of Natural Factors D3 and the bottle arrived wrapped like it was new, but the bottle was empty. These are not cheap, and to receive it like this is disheartening. Would give it 0 stars if I could.

So much easier than the drops for my 1.5 year old. He loves taking his daily "vitamin."In regard to the post claiming the magnesium stearate prevents absorption, this has been disproven by many scientists:"One in vitro study conducted in 2007 found that tablets containing magnesium stearate dissolved more slowly than tablets without magnesium stearate when placed in artificial gastric juice. (1) The study authors concluded that in vivo studies are needed to determine whether this finding has any practical significance. However, an earlier study found that although magnesium stearate increased the time it took for a drug to dissolve, it had no effect on overall bioavailability, as evidenced by blood levels of the drug in test subjects. (2) Further, another study found that levels of magnesium stearate didn’t affect tablet dissolution at all. (3)All of this indicates that although magnesium stearate might affect the rate of tablet dissolution in some circumstances, it doesn’t affect the overall bioavailability of the drug or supplement.1.

I started buying these when my son's pediatric urologist recommended he be on Vitamin D for problems with digestion and a small bladder. The D3 has worked wonders for him. He loves the taste so much, he often will remind me to give him his D3! The company ships the vitamins reliably and with appropriate expiration dates. I'm very pleased with the product and the company.

Great taste and very easy for small children to chew and swallow!

I bought these for my boys age 5 and 11 as most kids these days they spend more time indoors than out so I decided to start them on these vitamins. I have noticed they have more energy and are not walking around tired anymore. They have been going outside and jumping on the trampoline and just playing more outside. I recommend these to anyone who has kids that are inside the house a lot it is a great product I am very happy that I purchased these vitamins.
