Vitamins and Supplements Letter Vitamins Vitamin D

NOW® D3 + K2 Chewables combines vitamins D3 and K2, two nutrients extensively researched for their roles in the health of bones, teeth and the cardiovascular system. Vitamin D3 works with calcium to support bone health, and more recent studies indicate it’s important for immune system health as well. MenaQ7® MK-7, a trademarked ingredient in NOW D3 + K2, is a unique soy-free, bioavailable form of vitamin K2 that plays a critical role in arterial health through its ability to support proper calcium metabolism in blood vessels and arteries. Vitamin K2 is also important for the formation of strong, healthy bones.

Support immune health with Enzymedica® Vegetarian D3 + K2, a vegetarian formula uniquely whole-food sourced from shiitake mushrooms and chickpeas, delivers 5,000 IU of D3 and 90 mcg of K2 for immune and bone support. While vitamin K2 is essential for its benefits for our bones, vitamin D3 is essential for multiple health benefits, including immune health, strong bones and cardiovascular health. Enzymedica Vegetarian D3 + K2 also provides inulin, a prebiotic from organic blue agave, to help support the digestive system. Enjoy 1 capsule daily with food and reap the benefits of Vegan D3 + K2.

Support your body’s natural defenses with the Swanson Immune Health Bundle, a targeted trio of everyday wellness essentials: high potency Vitamin D3, Vitamin C with Rose Hips and Zinc Picolinate. Together, these immune-supporting nutrients help fill common nutritional gaps while promoting whole-body wellness—from immune system function and antioxidant protection to bone, muscle, skin and vision health.

Each nutrient in Swanson Daily Immune Essentials supports immune health through a distinct, complementary pathway. Vitamin D3 helps maintain healthy vitamin D levels, which are needed for normal immune cell activity, while also supporting calcium absorption for bones and teeth, muscle function and nerve signaling. Vitamin C works as a water-soluble antioxidant, helping protect cells from free radical stress, and it also supports immune cell function as well as collagen formation for healthy skin—your body’s first line of defense. Zinc Picolinate supplies an essential trace mineral involved in hundreds of enzymatic reactions, including processes related to immune cell development, protein and DNA synthesis, cell signaling and skin health.

Designed for consistent daily use, this 2-month bundle brings together vitamin C, vitamin D3 and zinc in a simple routine that supports year-round wellness. Want a deeper dive into your body’s defenses? Check out The Science Behind Your Immune System & How to Keep it Strong.
