I love Dr Osborne’s supplements. I love that they are grain free and I don’t have to worry what additive are in them. They are the best vitamins. I buy all the vitamins I can from him. I had a hard time in the past finding vitamin D with vitamin k that is grain free. I buy my vitamins that I can from him. He doesn’t carry all the vitamins I need. I keep looking for him to sell more. Very happy😃

I love all of Dr. Osborne’s vitamins and know that I can trust them to be high quality and gluten free.

I like this because it comes with vitamin K which is crucial for better absorption and distribution.

I buy all of my supplements from GFS with confidence there is no gluten or other harmful ingredients. Since learning I am gluten sensitive this is critical to me. This particular supplement is powerful and effective because it is D with K. THANK YOU Dr. Osborne!!!

I’m so happy with this product. I have trouble swallowing pills, and this one is small enough for me to manage. I appreciate that the K and the D are combined into one and that it’s gluten-free
