Good product - it works!
I received the supplement 2 days after ordering. It arrived unbroken and the gel caps were not melted or stuck together. First let me describe the product: they are very small and easy to swallow. No odor and no taste. I have had to take Vitamin D for sometime as prescribed by my provider. My D blood levels were really low - less than 12ng/ml and I would be prescribed a once-a-week prescription of 50,000 IUs to take once a week for 12 weeks. My blood level would be where it needed to be - greater than 20ng/ml. But when I had to return in 3 months for repeat blood work, the level was back down below 12ng/ml. And, I would get another prescription not for a weekly dose. My insurance company no longer covers Vitamin D and I have to purchase over-the-counter. I saw the Naturebell promotion for D3 + K2 supplement and reviewed it with my provider. She said that 10,000 IUs per day is in the upper range for a dose (this is the amount one would get from direct sunlight). As I don't seem to retain/absorb it well and my sunlight exposure is limited, she was okay with the 10,000 IU dose. She will check my blood level again in 3-4 months. I have now been taking the D3 + K2 for almost 3 weeks and have had no adverse side effects. I feel good, energy level is more consistant since taking daily. I take 1 everying morning ... I try to take with a fatty food like butter on toast or cheese in an omelette as the fat helps it to be better absorbed. I do drink coffee and caffiene does interfere with the absorption somewhat. I also have some gut issues that interfere with absorption. The 10,000 IUs should be just right. So far, I am very pleased. As to the K2 helping with the absorpiton of calcium to the bones -- I'll have to wait and see. I had a bone scan done about 2 months ago and will repeat in about a year. I'm 74 years old and am looking forward to this supplement helping with some "old age" issues. I have used Naturebell products in the past (I am still using their Magnesium) and have been very satisfied. I have confidence in their products.

Great D3 and K2 product for immune support and energy
I recently learned that D3 is critical for energy as well as immune support. This is the brand I have been giving to my family and it works well as the pills are little, easy to swallow, and has no taste. Also, it has the K2 which is a necessary combo with D3 for absorption. With the price being this good, we will continue to reorder this brand.

This product is definitely effective!
Effectiveness: I've been taking this supplement for 2-3 years. I doubled up on the recommended dose because I live further north and don't get much sun exposure and I doubted effectiveness due to it's relatively low cost. I got a lab test in January and tested extremely high for Vitamin D. So, I definitely have no doubt about this products effectiveness now!! Follow the dosage on the bottle. I also love that this product uses coconut oil as the carrier and not a seed oil. That's why I initially chose this product over others.
