Vitamin D3 + K2 Parent and Child Bundle

Give your family the extra support they need in one balanced bundle. This combo includes the Adult strength Vitamin D3 + K2 Oral Spray and the Kids version—so you’ve got every member covered. As a parent, you’ll love the convenience of both sprays in one pack: no pills to swallow, no sugar-loaded gummies, one simple routine for you and one for the kids. Backed by science, developed for fast absorption, and perfect for modern family life.

In modern family life, packed schedules, variable diets, indoor lifestyles and limited sun exposure mean it’s harder than ever to ensure everyone gets enough Vitamin D—and the companion nutrient Vitamin K2 is often overlooked. This combo ensures you’re taking a proactive step:

  • Helping your child build strong bones and a resilient immune system, while making your own health a priority at the same time.
  • Avoiding juggling multiple supplement formats, sorting out pills, or finding kid-friendly versions separately.
  • Creating one simple daily habit: you spray yours, they spray theirs—easy to keep consistent.
  • Giving you confidence that your family’s base nutrients are covered, freeing you up to focus on the moments that matter.

Advanced multi-benefit formulation:


  • Vitamin D contributes to the normal function of the immune system, helping your body defend against everyday illnesses and stay resilient year-round.
  • Vitamin D & K2 combine to improve calcium absorption and direct it to where it's needed most; your bones, not your arteries.
  • Vitamin D supports normal muscle function, helping you to stay active everyday Vitamin K contributes to normal blood clotting.

Frequently Asked Questions

  • Expert Customer Service

Yes, all of our packaging is fully recyclable. Please see our Better Planet Project page for more information.

No. Our oral sprays bypass the primary processing of the digestive system, meaning they can be taken at any time of day, with or without food. The active ingredients are delivered directly into the bloodstream via the inner cheek.

Our oral sprays can be used under or on the tongue, but the most effective area is the inside of the cheek due to its rich vein system. This is also where we carry out our absorption testing.

The vitamin D3 contained in the majority of our vitamin D oral sprays is sourced from lanolin, which is derived from sheep wool.

Our K2 is MK7 (all-trans) K2VITAL® from Kappa Bioscience.
