One tablet provides 1000 mcg vitamin B12 and 100 mg calcium. The tablets have a prolonged release, which means the active ingredients are released gradually. The pack contains 110 tablets, enough for nearly 4 months’ use. The tablets are also suitable for vegans.
Vitamin B12 is a water-soluble vitamin that naturally occurs in animal foods such as fish, meat, poultry, eggs and dairy products.
Cyanocobalamin is a form of vitamin B12 that is synthetically produced, which means the substance is made in a laboratory or production process rather than being directly extracted from a natural source. Cyanocobalamin is widely used in food supplements.
Calcium is a mineral that naturally occurs in foods such as dairy products, green leafy vegetables, nuts and pulses.
Calcium carbonate is a common compound of calcium that naturally occurs in rocks such as limestone and marble, and is also present in shells and eggshells. In food supplements, calcium carbonate is used as a source of calcium.
Calcium naturally occurs in dairy products, green leafy vegetables such as kale and broccoli, nuts, seeds and certain types of fish like sardines.
Prolonged release means that a tablet is formulated so that the active ingredients are released gradually, instead of all at once.
