If vitamins had personalities, this one would be the reliable friend who actually shows up on time. I’ve been taking this D3 + K2 combo for a while now, and it’s officially part of my “things I do to feel like I have my life together” routine. The softgels are tiny, easy to swallow, and don’t leave you with that weird vitamin aftertaste that makes you question your life choices. Bonus points for being vegan and clean — no mystery ingredients or “why is this in here?” moments. I love that it combines D3 and K2, so I don’t have to play supplement math every morning. My bones feel supported, my conscience is clear, and my medicine cabinet feels slightly more adult. If you’re looking for a solid, no-nonsense vitamin that quietly does its job without drama, this one’s a keeper Read more

I’m very happy with this brand of D3 with K2 to help absorption. I really appreciate the clean, vegan formula. The product seems to be excellent quality and fresh. The gel caps are easy to swallow and don’t get clumped up or stick together. It’s odorless and tasteless. The 5.000 IU increments make it easy to dose. It’s a decent value at $26.45 for 60 caps, especially for a quality product, Read more

I used AI to identify this as one of the top-tier D3 + K2 supplements on the market, but at this price point, I’m looking for long-term justification to keep it in my daily routine. As someone who isn't vegan, I don't need to pay extra for plant-based certifications—I’m purely interested in bioavailability and measurable health benefits. It’s a solid product, but for the non-vegan consumer, the value must be proven in the lab results. It is the only way I know that would ensure that I am not just "pissing away my money". Read more

This brought my low Vit D level back up to the normal range. It doesn’t hurt my stomach (I have IBS). D3 with K2 is what my doctor recommended and it turned out to be very effective. As I said before in the headline it doesn’t taste like anything. I trust this brand. I have other supplements by them. Read more

Vitamin D3 + K2 was the first supplement I ever purchased from Sports Research and this decision eventually led to me relying on this company for a number of my supplements. Sports Research’s D3 product first earned my respect when I had changed over to them due to poor testing results in my D3 lab work. I didn’t change my dose, only the brand, yet five months later when I had my next round of labs completed my doctor asked “What did you change on your vitamin D intake?” My Vitamin D numbers had improved significantly. While I find that they are usually not the least expensive alternative, I have nonetheless determined that Sports Research has high quality products that deliver what they claim and are worth the price. I have changed over a number of my other supplements to this brand due to their reliable quality and the consistent good results I receive from using them. I also like that Sports Research products are produced in a USA cGMP facility. While all supplements sold in the USA (even ones made in other countries) are technically subject to cGMP rules, the reality of the situation is that USA production is a plus. USA producers are subject to on-site FDA inspections, whereas foreign produced products are almost entirely cGMP compliant only via paperwork and promises. While the FDA does have a handful of overseas inspection teams, they generally only inspect pharmaceuticals and don’t bother with supplement products. If you have been struggling to get your Vitamin D numbers up, this is the way to do it in my experience. Sport’s Research’s Vitamin D3 + K2 has delivered documented results for me. The K2 works in synergy with the D3 to increase the overall absorption rate. I take 2 of these daily (one in the morning and one at dinner) and my Vitamin D3 levels have been reliably right where my physician wants them for some time now. Read more
