Questions & Answers

6 Customer Questions


Is this a naturally derived Vitamin D or synthetic?
Answer by ChewyDec 21, 2019
RxD3 contains pure Vitamin D3 in the form of cholecalciferol.

My 5 year old dog weighs 16 pounds. How much of a dropperful would I put in his food twice daily?
Answer by ChewyOct 20, 2020
It suggests giving one drop daily.

My vet wants my cockatoo to take vitamin D 100-200 iu. Your liquid vitamin D is 3000 iu. Is that the total amount in jar and what does one drop hold in iu’s?
Answer by ChewyAug 06, 2020
One drop of this supplement contains 100 IU and 3000 IU per ml.

What kind of MCT oil is in this product?
Answer by ChewyMay 17, 2021
The MCT oil used in the RxD3 is extracted from coconut. It is a clear, tasteless oil and is a very stable carrier for vitamin D3.

RX vitamin D3

I give this to both of my dogs every day but would love for the dropper to last instead of breaking half way thru the bottle. Can you make it more durable?? It’s really hard to make it thru the whole bottle with a broken top!!

Looks healthy

I’m sorry I try to post my questions here before I purchase and it makes constantly error. I have 2 years old cat, 17 lbs and he is under weight control plan. 1. My cat is healthy but my apartment has no sunlight at all. Can I give him for help of sunlight which is vitamin D? 2. I feed him a lysine in wet food in the morning for his immune health. Can I give this one drop in wet food in the evening? Please answer me

Dropper falls apart

I don't even get through a quarter of the bottle every time before the top of the dropper separates from the plastic top. I have to throw away most of it and get a new one. It would be nice if the material was more durable.

Packaging Items

I purchased this medication for my cat. The box was toooo big for the amount of bottles ordered (8) wrapped in paper but loosly rattling around in the box. The bottles are glass and I was surprised none were broken, Considering the trip, delivery, and banging around while in process. I would suggest bundling these bottles in bubble wrap as the product itself does not come boxed.

Just like I get from my vet

I was happy to get on autodelivery of this medication since my dog needs to be on this going forward. This is exactly the same as I get from the vet. Super convenient. Yes, the dropper top is not well made and as you use the bottle the dropper cover fails. The mfg should do something about this issue for sure.

Two 15 year old cats ! 3 Drops in their wet food every morning.

My “Cat Only” vet who has been practicing for 45 years suggest this for all cats. Vitamin D levels are important ! The tasteless drops are easy to give to them with the eye dropper in the bottle. And of course CHEWY’S PRICE is the best as always.

Great packaging

This is the second time I’ve purchased this. I’m happy to say the dropper has been improved. Getting the correct amount in the dropper is easy and without fuss. Much better than before. AND I received it sooner than estimated!

Vitamin D3 very low dose

Purchased your Vitamin D3 supplement for my dog who is very Vit D3 deficient (determined by test). He requires 4000 IUs of Vit D3 per day. Your version of Vit D3 contains 100 IUs per drop. So you can do the Math! The ad for Vit D3 did not specify how low of a dose it is. In comparison, stsndard Vitamin D3 purchased at a store contains 1000 IU per drop. Disappointing!

Vet Recommended

This Vitamin D brand and strength came recommend by my vet when my dog’s bloodwork came back with a Vitamin D deficiency. She gets 6 drops in her food daily.
