Antioxidant support; Immune support
Adults with busy schedules who want simple daily antioxidant and immune support, or those with limited intake of vitamin C and zinc-rich foods.
Take 1 capsule once daily with a meal; taking with food may help reduce stomach upset from vitamin C and zinc.
Non-GMO; Vegetarian/Vegan; Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, or tree nut ingredients; Produced in a facility that processes these allergens.
Ascorbic acid functions as a water-soluble antioxidant and cofactor for collagen and catecholamine synthesis, helping neutralize free radicals and support normal immune cell activity.
Caution: May cause stomach discomfort in some people; taking with food can improve tolerance.
Zinc acts as a cofactor for numerous enzymes and supports normal development and signaling of immune cells while helping protect cells from oxidative stress.
Caution: High zinc intake may interfere with copper balance; avoid combining with other high-dose zinc supplements unless guided by a professional.
Vitamin C provides antioxidant activity in the aqueous environment, while zinc supports enzyme function and normal immune cell signaling; together they address overlapping oxidative stress and immune defense pathways. Using zinc bisglycinate may aid absorption, complementing vitamin C’s rapid uptake.
Label Warning: For adults only. Consult a physician if you are pregnant or nursing, taking medication, or have a medical condition.
Who should be cautious: People who are sensitive to high-dose vitamin C may experience stomach discomfort if taken without food. Those with a history of kidney stones or iron overload may want to discuss use with a healthcare provider. If you take thyroid medications or certain antibiotics, calcium, magnesium, or iron at the same time as zinc, absorption may be affected; separate timing may be helpful. People on anticoagulant therapy should consult a healthcare provider due to vitamin K interactions that may occur with other products in their routine.
Storage: Store in a cool, dry place after opening.
