Vitamin manufacturer Twinlab Corporation has launched a calcium-infused water into the US market.

The company said today (25 October) that its bottled water product, named TwinCal, is drawn from a spring that has one of the "highest naturally occurring calcium contents of any spring found within the US".

"TwinCal is naturally infused with calcium carbonate, which studies have shown the body absorbs as well as the calcium in milk. It also contains magnesium, a compound that helps the body better absorb calcium, and silica, a trace mineral found in bones and teeth", added the vitamin company.

The water, which contains 60 mg of calcium in each bottle, will be available in 24 packs of 0.5 litre bottles.

Twinlab Corporation manufactures and markets over 1,200 different nutritional supplements and science-based nutritional products, including a line of sports nutrition, vitamins, minerals, nutraceuticals, herbs and tea products.
