Immune support; Antioxidant support; Collagen and connective tissue support; Skin, bone, and joint support
Adults with high-stress or busy lifestyles and those who want extra antioxidant and collagen support from a buffered vitamin C formula.
Take 1 tablet once daily, preferably with a meal to enhance tolerance.
Non-GMO; Vegetarian/Vegan; Kosher; Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients; Produced in a GMP facility that processes other allergens.
Ascorbate donates electrons to neutralize free radicals and serves as a cofactor for enzymes that build collagen and support neurotransmitter and carnitine synthesis.
Caution: High intakes may cause digestive discomfort in some people; the buffered form is gentler on the stomach but start with food if sensitive.
Bioflavonoids act as antioxidants and may help recycle or spare vitamin C while supporting capillary integrity.
Caution: May interact with certain medications or sensitivities to citrus; discontinue if unusual reactions occur.
Calcium supplies a buffering mineral that reduces acidity and contributes to normal muscle and nerve function.
Caution: Total daily calcium from all sources matters; excessive intake may contribute to constipation in some individuals.
Acerola provides naturally occurring polyphenols and vitamin C–related compounds that add antioxidant activity.
Caution: Contains fruit-derived compounds; avoid if you have known sensitivity to acerola or related fruits.
Rutin is a flavonoid that may help protect cells from oxidative stress and support healthy capillary function.
Caution: May cause mild digestive upset in sensitive individuals; stop use if discomfort persists.
Vitamin C provides the primary antioxidant and collagen-building support, while the buffered calcium reduces acidity for gentler digestion. Citrus bioflavonoids, rutin, and acerola add complementary polyphenols that help protect cells from oxidative stress and may help preserve vitamin C activity.
Label Warning: For adults only. Consult a physician if you are pregnant or nursing, taking medication, or have a medical condition. Natural color variation may occur.
Who should be cautious: People sensitive to citrus bioflavonoids or acerola may wish to use caution. Those monitoring calcium intake may consider the added calcium content. If you take medications, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place after opening.

Vitamin C is a water soluble nutrient well known for its vital role in the immune system. Vitamin C is also necessary for the production of collagen (a structural protein in connective tissue) and is therefore important for skin, bone, and joint health. Vitamin C is needed for amino acid metabolism, neurotransmitter synthesis, and the utilization of many nutrients, such as folic acid and iron. It is also a highly effective antioxidant that can help maintain healthy tissues by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors. This product supplies calcium ascorbate, a buffered form of vitamin C that is bioavailable and non-acidic; it is enhanced with bioflavonoids, which work synergistically with vitamin C.
Take 1 tablet daily.
