Review: Weekly dose corrected my lab values - As a menopausal woman, and post bariatric surgery, my labs were showing a low Vit D. Rather than taking a dose daily, my MD stated a large dose weekly would suffice. I found Nivagen and have had no issues with it. In fact, my yearly labs are now very satisfactory, including my Vit. D!
Review: Easy and Affordable - This is a great way to get my vitamin D3 during the winter months. I take it every Monday instead of taking a D3 everyday. No side effects and I feel great. I think it also helps with being in a better mood but that is hard to prove that it is the D3. I would recommend this D3.

## Questions & Answers

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

**Q: Are the capsules vegan?**
A: No the capsules are not vegan.

**Q: what is K2?**
A: 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

**Q: Hi, is it equal to ip 60000 iu excipients as 60000 does not available online?**
A: The dosage is as on the bottle: 50,000 IU. That's a weekly dosage. I am not a doctor.

### ⭐⭐⭐⭐⭐ Easy and Affordable

This is a great way to get my vitamin D3 during the winter months. I take it every Monday instead of taking a D3 everyday. No side effects and I feel great. I think it also helps with being in a better mood but that is hard to prove that it is the D3. I would recommend this D3.

### ⭐⭐⭐⭐⭐ Works great!
*by M***S on December 13, 2021*

I was encouraged to really up my D levels after having calcaneal osteotomy with a graft that has been slow to heal/fill in. After switching to the once a week 50k Nivagen (had been on the 10k @ 5x a week Designs for Health supplement) my levels are now in the 80s range. The other supplement did take me from 31 for the last 5 years to the 50s range after 3 months so both are effective. I prefer the once a week option in this tiny pill as it's easy to take, is more affordable and lessens the number of pills I take in a day. As a side benefit, it's helped me get off the buproprion I'd been on for 5 years! Yay!
