Douglas Laboratories D-Sorb | Vitamin D3 in a Patented, Naturally Self-Assembling Nano-Colloid System for Enhanced Absorption | 30 Capsules

Easy to take. Good product and good company.

Excellent source of Vitamin D. Doesn't upset my stomach. Doctor recommended.

Does the job. Would purchase again. Capsules are small enough that those will difficulty swallowing horse pills, do not have to worry about.

These Vitamin D capsules are great!

Used for low vitamin d in blood. New test shows improvement.

Love it!

I have a great vitamin D deficiency and these are the perfect dose for me!

This is a high dosage vitamin D prescribed by my doctor for low D confirmed by blood test.Have consumed 2 bottles, one from Amazon purchased last month and another from my doctor's office. Both had serious leakage issues, some only had 1/3 of the yellow vitamin left inside the capsule. They leaked out into the pill dispenser (kept flat on a counter in an air conditioned room) and they leaked inside the bottles also.I called Douglas Labs to inform them to suggest their product needs improvement. The man on the phone asked where I bought them. As to the bottle from Amazon he replied in disgust saying, "We do not sell our products on Amazon" and basically blamed the product's problem on a third party seller. Regarding the bottle from the doctor he apologized and said I should tell the doctor to get a full refund. When I report this to my doctor today she said no one ever complained before and refused to grant me a refund.The issue with the leakage is you may not actually be getting 12500 mgs as you think you are.Due to poor quality controls and also the fact that the lab seems to not care when a customer complains I will rate this product 2 stars = I Don't Like It. I am being generous, as I probably should be rating it with 1 star.
