I was talking to a doctor friend of mine and she was telling me that Vitamin D3 is lost through our urine if it's not taken with Calcium? I had never heard this before, but wanted to see if anyone knows anything about this?

Sadly, that's 100% incorrect.
However, you do need fat to absorb vitamin D supplements properly. Many people who have trouble getting their levels up are taking it on an empty stomach or with very little fat.

Ah, that may be where I have a problem then. I had my gallbladder out a while back, so I can't tolerate too much fat at one time. I take my D2 at the end of the day before bed so though not completely an empty stomach, there's not much left there, and I try not to take in too much fat in the first place.
I believe you only need something like 14-20 grams for optimal absorption.
Generally, consuming it with dinner dose the trick as most foods have at least that much trace fat in them.
With all the usual fat soluble supplements we take, is 14-20g of fat the magic number needed to optimal absorption? I've never been able to find that info.
Idk, but if you just have a big enough meal or one containing some fat, you should be good to go. I see so many patients and people online who say " i can't get my Vitamin D up" and nobody has told them that they need a fatty meal to absorb it properly with a high enough dose (usually at least 5,000 IU daily)
A big enough meal like dinner will usually contain enough trace amounts of fat even if the meal is not necessarily "fatty".
Yea it seems a lot of people aren't aware of that.
I aim for at least 10g of fat with all my supplements (except the empty stomach ones) since so many are fat soluble. Hopefully it's enough to get the full absorption.
I tried the 50,000 iu per week method for years, could never get my vit d score over 40. I'm seeing a new doc who has me on s sublingual D3/K2 spray. He says it's so effective after a few days I will be incapable of catching the flu.
I remember reading that D3 absorption is enhanced by k2 and that you shouldn't take calcium. Taken with fat increases absorption too.
