Biotics Research Bio-DK Caps 10,000 IU

Some supplements arrive in a bottle. Bio-DK Caps 10,000 IU arrives like it has somewhere to be — carrying 250 mcg (10,000 IU) of vitamin D3 alongside a dual-K situation: 500 mcg of K1 and 75 mcg of K2 as MK-7, all tucked into a single capsule. That's a pretty packed little commuter.

Biotics Research — Rosenberg, Texas, their own facility, since 1975, making the kind of professional-grade supplements that don't need to brag at parties — built this one around a microemulsion delivery system. Which is a very science-y way of saying they put real thought into how the stuff actually gets where it's going (instead of just vibing in your digestive tract like it's on a gap year).

What's Actually in the Capsule

Each single-capsule serving contains vitamin D3 as cholecalciferol at 250 mcg (10,000 IU) — that's 1,250% of the Daily Value, for those keeping score at home — paired with a combined 575 mcg of vitamin K delivered in two forms: K1 as phytonadione (500 mcg) and K2 as menaquinone-7, or MK-7 (75 mcg). Rounding out the formula are two antioxidant enzymes, superoxide dismutase (SOD) and catalase, each at 20 mcg, both sourced from vegetable culture. The capsule shell is gelatin-based, and the formula includes gum arabic and sesame seed oil as part of its microemulsion architecture. It is gluten free and dairy free.
