BioCeuticals Ultra Potent-C® (200g
BioCeuticals Ultra Potent-C® (200g
Ultra Potent-C combines a high dose of various forms of vitamin C, together with zinc, vitamin E and betacarotene in an easy-to-mix-and-drink oral powder for immune system and antioxidant support.
2.45g of total vitamin C per 4g dose.
A blend of three ascorbates providing optimal delivery of vitamin C with minimal gastrointestinal discomfort.
Contains zinc chelated to an amino acid; known to enhance zinc absorption. In the amino acid chelate form zinc bisglycinate, zinc had an increased bioavailability of 43% in women.
Vitamin E and betacarotene provide additional nutritional and antioxidant support.
Mineral salts of ascorbic acid are buffered and therefore less acidic and potentially less irritating than ascorbic acid alone. Sodium ascorbate and calcium ascorbate are the most common forms. Sodium ascorbate generally provides 131mg of sodium per 1000mg of ascorbic acid, and pure calcium ascorbate provides 114mg of calcium per 1000mg of ascorbic acid.
Vitamin C content of various forms of ascorbic acid 
Ascorbic acid = 100% vitamin C
Sodium ascorbate = 88.9% vitamin C
Calcium ascorbate = 82.39% vitamin C
Roles of Vitamin C in Immune Cells
- The active ingredients contained in this product have not been shown to be contraindicated during pregnancy or lactation.
- The tolerable upper limit (UL) for vitamin C is 2000mg per day for pregnant or breastfeeding women aged 19 years and older, and 1800mg per day for pregnant or breastfeeding women aged 14-18 years.
- Do not exceed a daily intake of 200mg of vitamin C in patients with haemochromatosis.
- High doses of vitamins C or E may reduce the response to warfarin.[4,5]
- Medications that may lower vitamin C levels include aspirin and corticosteroids.
- Taking more than 40mg of zinc per day over a period of weeks may interfere with copper bioavailability.
- Substances that may affect zinc absorption or excretion include high dietary calcium intake, coffee, folate, supplemental iron, NSAIDs, antibiotics and diuretics.
