Many customers said they only received a 12-capsule bottle. What’s up with that?

Thank you for your question. We understand the concern. As you will note, those complaints are from over a year ago and were due to errors at Amazon's end. Amazon fulfills our products for us and they kept mistakenly shipping customers 12-count bottles instead of 100-count bottles. (You can also see this fact in the photos the customers posted - they show 12-count bottles.) We decided to no longer sell the 12-count bottle on Amazon and have all leftover 12-count inventory shipped back to us. Since then there have been no more issues. Please do let us know if ever there is an issue with one of our products. We hope this helps assuage your concerns. Sincerely, Nivagen

this is what I found. Story at-a-glance Vitamin K2 is an important fat-soluble vitamin that plays critical roles in protecting your heart and brain, and building strong bones. It also plays an important role in cancer protection The biological role of vitamin K2 is to help move calcium into the proper areas in your body, such as your bones and teeth. It also helps remove calcium from areas where it shouldn’t be, such as in your arteries and soft tissues The optimal amounts of vitamin K2 are still under investigation, but it seems likely that 180 to 200 micrograms of vitamin K2 might be enough to activate your body’s K2-dependent proteins to shuttle calcium to the proper areas If you take oral vitamin D, you also need to take vitamin K2. Vitamin K2 deficiency is actually what produces the symptoms of vitamin D toxicity, which includes inappropriate calcification that can lead to hardening of your arteries If you take a calcium supplement, it’s important to maintain the proper balance between calcium, vitamin K2, vitamin D, and magnesium. Lack of balance between these nutrients is why calcium supplements have become associated with increased risk of heart attack and stroke

Hi, is it equal to ip 60000 iu excipients as 60000 does not available online?

The dosage is as on the bottle: 50,000 IU. That's a weekly dosage. I am not a doctor.

Vitamin D3

This Vitamin D3 capsules is great. I have a habit of forgetting to take my vitamin D3 and my level has been low since 2023. I ordered this last year December to take. I had a blood test taken today and my vitamin D level is normal on the higher range. My energy levels are good, I now longer feel fatigued. The vitamins are easy to swallow and the size of the capsules are good.I will say with this vitamin, because it is a high dose have your vitamin D3 level checked by your physician just to ensure that your levels are good.
