Once-Weekly Vitamin D3 50,000 IU Softgels, 50 Count Bottle, High Potency Vitamin D Supplement, Easy-to-Swallow, Extended Supply

I am very satisfied with ULTRA-D3 50,000 IU. The capsules are small and very easy to take, and I love that I only need one per week. After using it for several weeks, I have noticed a big difference in my energy and overall well-being. I really like that it is a high-potency formula and that it supports the health of bones, teeth, and the immune system. I also appreciate that it is gluten-free and of excellent quality. I definitely recommend it for anyone looking for a practical and effective way to maintain good vitamin D levels. Excellent product and very good value for money!

I’ve been using this brand for a full year now. For the last 5 years I’ve been on prescription vitamin D and changed to this due to the cost being so much lower. I’m happy to share that my vitamin D has maintained the same level using this product in place of the much more expensive prescription. Excellent value and easy to swallow. Highly Recommend

I was excited to find this was available in a larger quantity! I had been purchasing it in the smaller qty (I think 12 or 15? ) that comes in a box. The larger qty is a better fit for me as I have to take it at least 3x weekly!! I've tried a few brands, and was disappointed every time. I found this and OMGosh so pleased with how noticeably it works for me!! This brand had been my GO-TO brands since! That was almost 2 years ago! I can't recommend it enough!!

This product really worked for me! My vitamin D level increased from 18.9 ng/mL (deficient) in January 2026 to 51.6 ng/mL by June 2026 after taking it as prescribed. If your doctor has prescribed a high-dose vitamin D supplement, I would definitely recommend giving this one a try. It was effective for me, and I’m very happy with the results.

Taking weekly. Happy with my purchase.

Good brand, but I miss the smaller blister pack they used to sell. I don't go through these quick and blister packs are better for storage IMO.

It does make a difference In the way I feel

Works just as well as the prescription for a few dollar less makes it a good bang for your buck. Size is small and easy to swallow. Definitely helped my vitamin d levels and I can tell when I dont take it.

It seemed all right at first. The first row of capsules was fine. When I started on the second row, as I moved down the weekly dose I found 3 capsules broken and leaking. I threw then away. Not accidental that the last 3 capsules were leaking inside their individual pouch. Disappointed I could not finish the course. Angry over the financial loss. As for any benefits? I have to question if this product is even genuine. All these weeks, I have kept the product safely inside its original container in a cool. Dark place. Guess I will only know if I do the test again.
