The Bahamas are the closest tax haven to the United States. As far as tax havens go, the Bahamas are one of the largest in land area. With over 700 islands and cays (pronounced key) totaling 5,400 square miles, only Panama, Vanuatu and Switzerland are bigger.
Calcium citrate is a calcium supplement derived from citric acidâa substance commonly found in citrus fruits and other fruits and vegetables. While calcium citrate is an acidic form of calcium, calcium carbonate, another calcium supplement, is alkaline based.
Many natural calcium carbonate preparations such as oyster shells or bone meal contain some lead. The low lead levels in calcium supplements are unlikely to be a health risk because calcium blocks lead absorption. Calcium citrate is well absorbed in the fasting state. Calcium doses above 500 mg are not absorbed as well as smaller doses, so large doses of supplements should be taken in divided doses (eg, in the morning and evening).
