Does your calcium contain any lead?
The lead limit for all of our calcium products is well below the federally adopted USP (United States Pharmacopeia) and California Proposition 65 regulations. The current California lead limit, effective April 1, 1999, allows for a maximum of 1.5 ppm of lead per 1,000 mg of Calcium (which is even lower than federal guidelines that allow for a maximum of 3 ppm of lead calculated on calcium carbonate).
What are some dietary sources of Calcium 750 mg with D and K?
Please note, because of the chemical similarity between calcium and lead, all calcium supplements have trace amounts of lead in them. Even supplements that report non-detectable amounts may have some lead in them depending on the study equipment used. Our equipment for detecting lead is very sophisticated and accurate. It is essential that our equipment be very precise since we have to be able to detect even trace amounts of lead in our products.
Calcium needs range from 1000-1300 mg per day. Many Americans do not take in enough calcium from their diets. Common calcium containing foods include: Milk, Yogurt, Cheeses, Calcium fortified juices, and dark green leafy vegetables.
What is your calcium derived from? Is it from oyster shell?
Vitamin D is obtained from sunlight, foods and supplements. Many people have low levels of vitamin D. Vitamin D is found naturally in very few foods. Natural sources include: Salmon, sardines, mackerel, and other oily fish. Vitamin D is also found in egg yolks in smaller amounts. Some foods are also fortified with vitamin D, these include milk, yogurt, cheese, some cereals and juices. Read the labels to determine the amount of vitamin D in these foods.
High Vitamin K food sources include green leafy vegetables, such as spinach, kale, collard greens and green lettuce. Vitamin K can also be found in lower amounts in vegetable oils, such as olive, canola and soybean oil.
Our calcium is derived from limestone, not oyster shell.
Why do I need to take a calcium supplement?
National nutrient intake data shows 49% of American adults fail to meet the recommended calcium intake through dietary sources.1 Calcium is an important nutrient, particularly for teens as well as post-menopausal women and older men. There are increased daily intake recommendations for individuals at these specific lifestages including 1300 mg for teens as 1200 mg for post-menopausal women (51 - 70y) and older men (>70y) compared to 1000 mg for adults (19 -50y).2 In general, you need to consume three or more servings of calcium per day to meet the daily requirement. One serving would be approximately one 8 ounce cup of milk, 6 ounces of yogurt, or 1 ounce of cheese.
