iHerb Customer Reviews

Excellent value and quality

Posted by iHerb Customer on Feb 04, 2018 | Verified Purchase

This is my second reorder of this product. It's hard to find D3 in 5,000 IUs. This product works for me and is excellent value.

Thanks for your feedback!

feel more alert, less dark

Posted by iHerb Customer on Jan 24, 2018 | Verified Purchase

helps with my fatigue and lethargy but subtle difference only. on days that i didn't take it, i felt so blue and depressed. so this helps me be more alert.

Thanks for your feedback!

Power Dose Love it

Posted by iHerb Customer on Jan 23, 2018 | Verified Purchase

This is a great product for me. I get no sunshine so vitamin D is nil. This seems to help my energy level, pain in the legs especially lower limbs. I think it is helping reduce my blood pressure a notch and allergies. You cannot get this strength in vitamin D in my country so I happy to buy this. The value is unbelievable.

Thanks for your feedback!

This is a good cheap simple way to raise your vitamin D

Posted by iHerb Customer on Jan 16, 2018 | Verified Purchase

This tablet is much easier (because popping a small pill is easier than having a bad tasting liquid version) to use daily to bring up your vitamin D. I had my levels measured before and after taking a bottle and they had risen.
