1Why Not NaturalWhy Not Natural Organic Vitamin D3 K2 (MK-7) Liquid Drops, 5000 IU of sublingual D3 with Coconut MCT Oil, for Strong Bones and Teeth, Heart and Immune Support
Main highlights- SIMPLE INGREDIENT LIST: Every ingredient in our formula has a purpose! Our formula is vegetarian (the vitamin D is derived from lanolin, a byproduct of wool production, and the K2 comes from nattō), keto-friendly, non-GMO, gluten-free, and 3rd party tested.
- ORGANIC PEPPERMINT OIL: We use real peppermint oil (similar to essential oil, but at a lower concentration so as to protect the microbiome) which supports digestion and gives it a refreshing, breath-freshening taste!
- MCT OIL - This coconut-derived oil supports energy, metabolism, and the brain. Vitamins D and K should always be taken with fat (like MCT), so this supplement can be taken with or without food!
- HIGH POTENCY - With 5,000 IU of D3 and 100 mcg of organic K2 per half dropper liquid serving to quickly build up vitamin D levels and support your bone health and immune system.
- DESIGNED FOR ABSORPTION - Same bioactive form of Vitamin D as sunshine plus Vitamin K2, which helps move calcium to bones and teeth (and improves absorption!), and away from soft tissues like arteries.
