We have used the Sports Research D3-K2 for many years. Our Dr. said we must be using a good product since our D3 levels are always very good. Sadly to say I had to quit using the product when they put the curcumin in the tablet. It causes me to have heartburn now. However, my husband continues to use this wonderful, quality product.
I’ve been taking these for a couple of years but just read a book talking about how so many of the ingredients in most supplements on the market are from China or other places that aren’t regulated byt then packaged here in the USA. Are your products ingredients from the USA?
I really prefer the packaging of Sports Research products. Easy to open. Nice quality. No fussy pill tops. The pop top is where its at. These pills are small and easy to swallow. Don’t know yet if its raising my Vit D but in the winter a supplement is necessary.
I really like your product. Was referred by a Therapist friend of mine. Said he really did his research on your products.
