Let customers speak for us
Have been taking these vitamins for many of the years since open heart surgery with aortic valve replacement in August 1990!
I have been using Clotacin since before, when it was called Clotamin.
It has no Vitamin K and is good for older people on an anticoagulant.
I really like this supplement. They don't smell good but they don't have an awful taste when going down! Very easy to swallow. These did not affect my INR level at all.
Excellent vitamin for those on blood thinners. So thankfully I found this. Courteous staff. Always sending a thank you note with every purchase.
Shipping was only 2 days. I've been using the Clotacin product for many years now in order to have a multi-vitamin without the Vit. K as I am on blood thinners.
Great product I’m glad it exist I told my care team about it they didn’t know and they are always weary of some of these supplements.
Confident I have a multi that does NOT effect my warfarin levels. I have already made several 6 month purchases and will continue to use.
Essential for those of us who must take warfarin. I'm glad this is available.
I am on a blood thinner and can't take most multi-vitamins. Clotacin meets and exceed all my vitamin needs.
Clotacin has been great for my son, he's a teen on Warfarin. Like all teens, he probably doesn't eat exactly like he should. Clotacin gives us that assurance that he is at least getting the vitamins his body needs without affecting his INR levels.
As a first-time buyer, I emailed with a few questions and was pleasantly surprised to hear directly from Kelly, one of the owners. She was friendly, helpful, and even placed my order for me. Wonderful customer service!
