This mini patch is formulated with a full daily dose of vitamin D3 and vitamin K2, which work synergistically to keep your body strong and healthy from the inside out—no matter the season. Vitamins D3 and K2 have been shown to support bone health, boost energy levels, enhance mood, support immune function, and help compensate for a lack of sun exposure.*
Each pack includes 36 mini patches—enough for a full month of daily use, plus 6 extra patches to share!
A third-party, randomized parallel pilot trial found that vitamin D is systemically absorbed through the skin when applied using our transdermal patches, reducing vitamin D3 deficiency among participants from 23% at baseline to 0% after 8 weeks.
The patches are ½" in diameter, made from 100% recycled PET, and come on a clear backing.
