Vitamin C functions as an electron donor that helps neutralize free radicals and serves as a cofactor for enzymes involved in collagen formation and neurotransmitter synthesis.
Caution: High-dose vitamin C may cause digestive discomfort in some people; taking with food can help tolerance.
Citrus bioflavonoids provide polyphenols that may help stabilize vitamin C and support antioxidant activity in tissues.
Caution: May interact with certain medications or sensitivities to citrus-derived compounds; discontinue if unusual reactions occur.
Rutin is a flavonoid that may help support capillary integrity and antioxidant defenses by scavenging reactive oxygen species.
Caution: May cause mild gastrointestinal upset in sensitive individuals; take with food if needed.
Acerola provides natural vitamin C and polyphenols that contribute to antioxidant activity and complement ascorbate uptake.
Caution: Contains natural fruit compounds; those with fruit sensitivities should monitor for tolerance.
Calcium supports normal cellular signaling and, in buffered vitamin C, reduces acidity to make ascorbate gentler on the stomach.
Caution: Total daily calcium intake from diet and supplements should be considered to avoid excessive amounts.
Ascorbate supplies core antioxidant and collagen-related support, while bioflavonoids and rutin add complementary polyphenols that help sustain antioxidant activity. Acerola contributes natural vitamin C and plant compounds that align with the formula’s oxidative stress support. Calcium buffers the ascorbate to be less acidic for the digestive tract.
Label Warning: For adults only. Consult a physician if you are pregnant or nursing, taking medication, or have a medical condition. Keep out of reach of children.
Who should be cautious: People with a history of kidney stones or sensitive stomachs may wish to start with a lower dose of vitamin C and discuss with a healthcare provider. Those monitoring calcium intake should be mindful of the added calcium. If you take medications, discuss potential interactions 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 protect the body's cells and molecules from damage by free radicals and reactive oxygen molecules 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.
