The Premier Vitamin D3 + K2 is great! This brand is high quality and effective based on lab bloodwork I recently had to determine my doctor recommended vitamin D levels. It absorbs better than the brand of vitamin D that I previously took. I take 1 capsule per day with meals. It is easy on the stomach and I have no after effects. The labeling on the bottle is aesthetically appealing and easy to understand directions for use. My order arrived promptly and was packaged for safe shipping and handling. I will definitely order this product from iHerb company again.

This product is excellent for people who don't get enough sunlight daily. This product is on my monthly supplement order with iHerb. The size is good and I had no problems taking them. The quality is excellent and the ingredients are all natural with no additives. I am very happy with this product line. Please go to their website for additional information you will not be disappointed.

It is a product made by a great, reputable company. Also, because it is a strong product, I only have to take it every other day.

looks like good quality, the size is easy to swallow. I think it works well.

Amazing I love all products from premier research labs

Great, I tried it from the beginning of Ramadan, this is the best type because it is a mixture between vitamin D & K2, and this helps to benefit from vitamins

On the recommendation of the therapist, I take exactly the composition of D3 and K2, since assimilation goes better in this combination. We will drink for a month and retake tests.

it is an excellent product the quality is also excellent it contains the ingredients that my body requires and the dose is recommended

Champion product and hero manufacturing 👌 I took two boxes for the summer

I had a lot of body aches, after I started drinking this vitamin my body stopped hurting
