We tried quite a few different products but none brought my husband's level up. His levels always stayed low. With this product, his vitamin D3 level is 132! This is the ONLY thing that worked for him. Hallelujah!

Thanks for your feedback!

The best Vitamin D3 that works very Quickly, no big pills to swallow either. Even my doctor asked me what I used, I sent her the link.

My Vitamin D was always low, I bought these and after one week my vitamin D is on top again. I used the first week one per day. The second week I used one every second day because it is 5000 IU. Now I use once a month. Even my doctor asked me what I use, so I sent her the link. THE BEST PRODUCT EVER.

Thanks for your feedback!

Easy to take

I switched to Superior Source because I wanted the mirolingual formula. After taking Superior Source 5K IU Vit D3 for a while, blood test showed that my vit D level is remaining stable at a good high level.

Thanks for your feedback!

Love it!

I know it works - I have had my blood tested both before and after. Also someone told me another product upset their stomach but this one never will. It is just a microscopic sublingual that dissolves in no time - easy-peasy!

Thanks for your feedback!

Great product

I have been using this vitamin D for years. I used to be deficient but since I have used this my levels have increased significantly. It is a very small pill you put under your tongue and it dissolves. There is a little bit of a sweet taste but no real flavor. I would highly recommend!!!!!

Thanks for your feedback!

LOTS OF VITAMIN D ! (for the money)

Title says it all. Easy to take, too. No drops or big pills or hastles. Highly Recommend.

Thanks for your feedback!

I trust this D3

Posted by DesertLiving on December 26 2014 | Verified Purchase

I have had very low d3 levels and have had cancer in past years. This is the only d3 I take daily, along with K2 by life Extension. Superior Source works and my D3 levels have gone from 20 to 65-68 on quarterly bloodwork tests. It takes a couple months if you are depleted, but I even have less body aches and feel better knowing my d3 lvls are in normal range now.

Thanks for your feedback!

Love these microlinguals, so easy to take a high dose of D3. I also take the methyl B12 microlingual.

Thanks for your feedback!
