Take it once daily, ideally in the morning with a meal. Since vitamin D3 is fat-soluble, pairing it with a meal that contains healthy fats — like eggs, nut butter, or avocado — can help your body absorb it even more effectively.

Vitamin D3 dramatically increases calcium absorption — which is great for bone health but can lead to calcium building up in the wrong places (like your arteries) if taken alone. Vitamin K2 acts as a co-pilot, directing that calcium specifically into your bones and teeth where it belongs, making the combination far safer and more effective than D3 alone.

Yes. At 2,500 IU of D3 per serving, the dose is well within recommended guidelines for daily supplementation. The formula is third-party tested for purity and potency, and manufactured in an FDA-registered, cGMP-certified facility. As with any supplement, consult your healthcare provider if you have specific medical conditions.

Refrigeration is not required, though Rho recommends it for the best taste experience. The product is shelf-stable and travel-friendly, making it easy to keep in your kit bag or take on the road.
