Excellent product, has helped my health conditions
Back in 2016, I had a mild stroke. Blood tests revealed that my vitamin D level was very low. I started taking Sports Research Vitamin D3 along with another brand of vitamin K2. Within about a week my atrial flutter arrhythmia improved so much that everything seemed back to normal. I have had no recurrence of these symptoms, and my vitamin D levels now test in the high normal range. I have since changed to the Sports Research 2-in-1 K2 + D3 formula for economy and convenience. I appreciate that these products are vegan, non-GMO, and independent third-party tested.
