Buffered Vitamin C 1000 mg

• Vitamin C

  1000 mg

  Ingredient research · Vitamin C

  Vitamin C is an essential water-soluble nutrient that supports collagen production, antioxidant defenses, and the normal function of immune cells. Supplementation reliably prevents or corrects deficiency, can improve absorption of plant-based iron, and may modestly shorten the duration of common colds when taken regularly.

  • Supports lower common-cold risk during brief periods of severe physical exercise or cold stress.
  • Supports circulating Vitamin C status across studied healthy and clinical populations.
  • Supports short-term blood-pressure and endothelial-function outcomes in studied adults.
  • Supports fasting-glucose and HbA1c outcomes in adults with type 2 diabetes.

• Calcium

  112 mg

  Ingredient research · Calcium

  Calcium is an essential mineral that gives bones and teeth their structure and also enables muscle contraction and nerve signaling. Supplements are most useful for filling inadequate intake and, often alongside vitamin D, can help preserve bone mineral density and support fracture prevention in some higher-risk groups.

  • Supports bone-mineral-density outcomes in studied healthy children and older women.

• Citrus Bioflavonoid Complex

  From 25 mg Hesperidin (other related phenolic compounds)

  100 mg

  Ingredient research · Citrus Bioflavonoids

  Citrus Bioflavonoids are a mixture of citrus-derived plant compounds, often including hesperidin and related flavanones, that can influence antioxidant and blood-vessel signaling. They are mainly supplemented to support capillary and circulatory health or complement vitamin C, but distinct human benefits remain modest and depend on the extract’s composition.

• Rutin

  10 mg

  Ingredient research · Rutin

  Rutin is a plant flavonoid made of quercetin linked to a sugar group, and is taken mainly for its antioxidant activity and proposed support of capillary and venous function. Unlike some modified rutosides, Rutin itself has limited human evidence for circulatory benefits, while broader cardiometabolic or anti-inflammatory uses remain speculative.
