A fantastic third-party batch-tested Vitamin D3 and K2 oral spray in dark glass packaging. Three sprays equate to 4,000 IU of plant-based vitamin D3 with 100µg of K2. You can reduce the number of sprays if you would like to reduce the therapeutic dose. Where many D3 and K2 sprays add sweeteners, thickeners, or preservatives, this product has just four ingredients: algae-derived D3, K2, MCT oil, and peppermint. Great for those looking for a clean, tablet-free, plant-based source of Vitamin D that does not need to be stored in the fridge.
