Product Description
Race travel, crowded start lines, and back-to-back training weeks are part of your calendar, and a daily immune routine belongs alongside them. Thorne's Immune Support Stack gives you vitamin D3, zinc, and vitamin C with citrus bioflavonoids to support healthy immune function.
Vitamin D3 for immune and bone support – Vitamin D3 is the form your skin makes from sunlight, and this vegan liquid supports immune function, strong bones, and muscle strength, with a dose you set by the dropperful.
Zinc that supports your immune system and your skin – Zinc Picolinate gives you 30 mg of a well-researched zinc form chosen for absorption and tolerability, to support immune, skin, eye, and nerve health.
Antioxidant and immune support from vitamin C – Vitamin C with Flavonoids pairs 500 mg of vitamin C with 75 mg of citrus bioflavonoids from oranges to support your immune system and your body's antioxidant defenses.
Vitamin D3, also called cholecalciferol, helps your body absorb calcium and phosphorus and plays a role in immune and muscle function. Zinc picolinate is zinc bound to picolinic acid, and citrus bioflavonoids are plant compounds from oranges that Thorne pairs with vitamin C.
How to Use Thorne Immune Support Stack
Dose: Take ½ to 1 dropperful of Vitamin D3 daily, 1 capsule of Zinc Picolinate 30 mg daily, and 1 capsule of Vitamin C with Flavonoids one to three times daily.
