I've been using this Vitamin D3 K2 supplement for about a month now, and I have to say - it's become a staple in my daily routine. As someone who works indoors most of the day, I definitely don't get enough sunlight, especially during winter.

The capsules are slightly larger than average, but I've had no trouble swallowing them with water. What really stands out to me is the thoughtful formulation - the combination of D3, K2 MK7, calcium AND bioperine makes me feel like I'm getting a complete package for bone and immune health.

I haven't been sick since starting these (knock on wood!), though I can't say for certain it's because of these supplements. But what I do notice is more consistent energy levels throughout the day. The bottle says to take one daily, but after consulting with my doctor, I've been taking two (5000 IU each) since my levels were quite low.

The fact that these are made in the USA with non-GMO ingredients gives me extra peace of mind. The bottle lasts me a full month at my dosage, which is great value compared to some other brands I've tried. If you're looking for a high-potency D3 supplement that includes all the co-factors for optimal absorption, this one's definitely worth considering.
