Vitamin D3 and K2 are two of the most important nutrients for bone density, calcium balance and cardiovascular health, and they work as a team, D3 helps the body absorb calcium, while K2 helps direct it to bones and teeth rather than arteries. Our range combines natural, plant-based D3 from lichen with bioactive K2 MK-7 from traditional Japanese natto fermentation, suspended in organic MCT oil from coconut for absorption and purity.
There are two ways to take it. Vitamin D3 + K2 MK-7 provides 5,000IU of vegan D3 and 200mcg of all-trans MK-7 in organic MCT oil, a clean, effective pairing for strong bones, immune support and balanced calcium metabolism in one daily softgel. Vitamin D3 + K2 Advanced Complex keeps that high-strength foundation and adds Magnesium Glycinate, Calcium Citrate Malate and Zinc Picolinate for broader mineral support, with magnesium helping activate vitamin D and zinc supporting mineralization and immune balance.
Both are produced with gentle, solvent-free extraction and multi-stage filtration to remove residues and keep the actives clean and stable, with each softgel nitrogen-flushed before sealing to prevent oxidation. Our all-trans MK-7 is over 99% pure, the form that stays active in the body longer. Everything is toxin-free, non-GMO and tested for heavy metals, solvents and stability under cGMP-certified conditions.

GREAT PRODUCT!!! I've been on this product for at least 10 years. There was an almost immediate reaction to an issue I have with my hip, due to the previous 3 surgeries on that area. I will not and cannot go without this product.
This product is one of excellent quality. In a single daily pill, you have 50 mg. of Lycopene. Taking lycopene might slightly reduce the risk of developing prostate cancer. It might also slightly reduce the risk of prostate cancer coming back.
I found this company when they were new about a decade ago on eBay & have been singing their praises to everyone I know talking about wanting a good collagen supplement. There were hardly any of any other collagen products on the market that had all of the different types of collagen in it like UltraColl. Most have type 1, 2, 3 but few have type 7.. There is SO MUCH misinformation out there on what collagen types help what things in your body you’re trying to aid. For me it was everything from my spinal chord injury/surgery that gives me chronic pain, stiffness, etc to skin & hair.. I love that they have stayed true to who they are & after all these years still offer an amazing product at a very reasonable price! If you’re thinking of starting a collagen product do yourself a favor & try UltraColl.. Give it atleast 3mos to notice results. I promise, you will not be sorry! And if you try other brands that are popular right now, in the process, you’ll understand why you’ll always come back to UltraColl! They are the best! Truly!
Here’s a bottle I found w/their old label, so prob from back in like 2008-10ish... Still love this awesome brand!
Thank you ULTRACOLL! You are the Bestest!
Hello ! Some days ago I got 6 bottles of Glucosamine and Chondroitin 1500 but the signs on the bottle , its weight , the tablets themselves have a difference with what I got with your company 2 years ago . Did you change anything in this production ? Besides it s not easy to swallow the tablets now . There is some powder on the bottle walls inside .
If not the best Korean Panax Ginseng is right there at the top. I´m so glad I found the us.pureclinica website and that I was able to buy it from you eventhough I don´t live in the USA. Thanks.
