This is effective and I love it!

Posted by iHerb Customer on Jun 26, 2012 | Verified Purchase

I have the VDR (Vitamin D receptor genetic defect and need to take 50,000 IU D3/week. The 50,000 IU pill nauseated me so I bought this over the counter instead. I take it 5 days/week and take 2 days off and it keeps my D3 blood test at 70-80 where it should be according to Life Extension (www.lef.org). I did try taking this every day because I am a creature of habit, but that drove my D3 up to 100 (which was deemed borderline ok) however this was not ok because it made me prone to urinary tract infections at 100 because it changed my ph (so watch for that). (UTI's are disaster for someone with high blood pressure as your blood pressure supplements (including drugs) do not work when your kidneys don't). This pill is very pleasant. Someone told me their D supplement caused stomach upset but this one never will. Just make sure to take weekends off it you take this dose.

Thanks for your feedback!

As a muslim it is hard to come across a vitamin d3 that contain high (10,000 UI) vitamin with vcaps. Only some of gelatin we can actually consume (halal). So i highly recommend this Superior Source,D3, Extra Strength,MicroLingual. Its dissolve really fast in my mouth, the taste is not that bad. And it really works. You need to consume this with vit k for better absorption eat vegetables like kale , broccoli and spinach, these veges contains more vit k than other vegetables .

Thanks for your feedback!

This tiny little pill makes it so easy to take. This supplement dissolves in your mouth, which I love because I have trouble swallowing pills. It only took 2 weeks for my Vitamin D level to become normal.

Thanks for your feedback!

Superior Source, D3, Extra Strength

Posted by iHerb Customer on Oct 27, 2014 | Verified Purchase

I purchased this product for my horse. She has PPID (Cushings Disease) and couldn't shake skin infections. I started with 2 daily and after great improvement in 2 months, I now administer 1 daily with Prascend Pergolide for PPID! It as hard to find a D3 in a high dosage... this works very well for my horse. I administer it in a syringe with a bit of water and she takes it super easy. It breaks down quickly. Thank you!

Thanks for your feedback!

Strongest D That I Could Find

Posted by iHerb Customer on Jun 29, 2013 | Verified Purchase

More expensive than regular D but worth it if as strong as claimed. Needs some studies to compare sublingual with swallowed, and how long D levels take to build up in the body.

Thanks for your feedback!
