THORNE - Vitamin D3 Supplement - Supports Healthy Bones, Teeth, Muscles, Cardiovascular & Immune Function* - Gluten, Dairy & Soy-Free - 1,000 IU - 90 Capsules

I had to get a low dose, due to my current high calcium level. Once I have surgery I will go up to 5000 ui a day instead of this very low dose. It's too low for most people. Make sure you take vitamin K2 and magnesium with it to work properly. Also, it is a FAT soluble hormone. Take it with fat or it won't work properly. Eat healthy with it (animal fat or olive or grass- fed butter, for example).

I cannot judge the effectiveness after a couple of weeks, hopefully it is good given that Thorne is USA Olympic team sponsor. The good thing is that the vitamins are really tiny and easy to swallow - I know some have issued and cant easily swallow pills

I trust Thorne brand to get quality vitamins

Love all of Thorne's products, especially their Vitamin D. The quality and price point can not be beat.

Trying Thorne supplements for the first time. They are very thin capsules and I do believe the content will be absorbed into my system.

I Absolutely love THORNE SUPPLEMENTS! They are Pure Quality!

These pills are one of the few left that aren't made out of a soy product.

The capsules were half empty, some of them. Way too expensive.

I haven't taking this long enough to give a review.

Just received the 4 bottles of Thorne D3 I ordered. Each bottle contains 90. Recommended dose is 1 per day, so each bottle lasts 90 days. I ordered 4 bottles. That's 380 days worth of recommended servings. Every single bottle expires in 6 months. I have two other bottles I previously ordered, that don't expire for 2 years. If you're going to be selling products so close to their expiration date, you need to let consumers know prior to their purchasing them. Which you did not.
