Calcium supplements derived from natural sources such as bonemeal, dolomitic limestone and oyster shells may contain high amounts of lead. Just because a product is labeled "all natural" does not mean it is lead-free. Some over-the-counter calcium preparations may contain dangerous amounts of lead.
Supplementing one's diet with calcium has been shown to decrease the amount of lead the body absorbs - as more calcium is absorbed by the body the less lead gets into the bloodstream. Thus, it is often advised to increase one's calcium consumption to prevent lead poisoning. However, taking lead-contaminated calcium supplements gets the exact opposite result - even more lead in the body!
The best way to add extra calcium is by following a healthy diet that contains calcium-rich foods such as dairy products, sardines, and salmon, as well as vegetarian sources such as kale, turnip greens, spinach, broccoli, almonds, and peanuts.
If you decide to supplement your diet with store-bought calcium, look for preparations that specifically state "lead-free" on their labels.
