Disclosure: I got this product as part of an advertorial.
The ingredients list indicates the only factor of D3 component is coconut oil; basically you are consuming pure coconut oil. I suppose if you normally consume a lot of coconut oil in your diet, you would not need to take Vitamin D3 supplements.
There are 180 softgels in the bottle, and you take one per day, so that's a 3-month supply, which isn't bad for the price. My only concern is that the general recommended daily dosage of Vitamin D3 is 4000 IU, but these pills offer 5,000 IU. Not a HUGE concern, as these are fat-soluble pills so overdosage won't kill you, but like I said, if you have a diet that already contains lots of Vitamin D3, this product may be unnecessary.
I received one or more of the products mentioned above for free using Tomoson.com. Regardless, I only recommend products or services I use personally and believe will be good for my readers.
