Liquid Vitamin D3 & K2

Liquid Vitamin D3 & K2 is an unflavored liquid formula that pairs two powerhouse nutrients — vitamin D3 (cholecalciferol) and vitamin K2 in its superior MK-7 form (menaquinone). Together they support strong bones, healthy circulation, immune function, and brain and nervous system health. The liquid delivery form is easily absorbed, making it a convenient daily addition to your routine.

Vitamin D3 plays a critical role in structural support for bones, muscles, and teeth, while also activating both branches of the immune system and helping to boost mood. Vitamin K2 (MK-7) supports healthy circulation by helping guide calcium to the places it's needed most — like bones and teeth — while working to slow the deposit of minerals like calcium in arteries. Together they optimize calcium usage so it gets to all the right places and avoids the wrong ones.

Once daily, add 5 drops to any beverage or food, or simply take them straight from the bottle. Each 30 ml bottle provides a 120-day supply, so a single bottle goes a long way.

It's a great choice for adults looking to support bone density, heart health, circulation, and immune function in one easy daily step. It may be especially helpful as we age, since guiding calcium to bones and away from arteries becomes increasingly important over time. Anyone who is pregnant, nursing, or taking prescription medication should check with their healthcare provider before starting.

If you're primarily after vitamin D3 in tablet form, Nature's Sunshine offers a standalone Vitamin D3 (180 tablets). For broader bone support with calcium and magnesium, Calcium-Magnesium SynerPro (150 tablets) is worth a look. Krill Oil with Vitamin K2 (60 capsules) pairs K2 with the benefits of krill oil. For cardiovascular-focused support, Solstic Cardio and Solstic Twenty-Four come in convenient single-serve packets. Liquid Vitamin D3 & K2 stands out by combining both D3 and K2 in an easily absorbed liquid with a generous 120-day supply.
