Kirkland Signature Calcium 600 mg. with Vitamin D3, 500 Tablets Exp. 09/24
Kirkland Signature Calcium 600 mg with Vitamin D3 is an important part of your daily regimen. Taking one tablet two times a day with a meal provides a daily intake of 1200 mg of calcium and 20 mcg (800 IU) of Vitamin D3. Calcium is a key mineral that supports many functions in the body. Vitamin D supports the action of calcium, so they work synergistically:
• For strong bones and teeth†
• With Vitamin D assisting in the absorption of calcium†
Adequate calcium and vitamin D, as part of a balanced diet along with physical activity may reduce the risk of osteoporosis later in life.
Of all the minerals, Calcium ranks among the highest in terms of quantity in the body. While calcium supports a variety of functions in the body, such as muscle contraction, one of its most important jobs is to give structure and integrity to bones and teeth. In fact, calcium is pulled in and out of bones during normal processes.
Bone health is a sum of several factors including genetics, environment, life-style and nutrition. Calcium is just one ingredient in the “recipe” for healthy bones. Vitamin D is another nutrient that is important because it helps with calcium absorption, so calcium has a better chance of getting where it needs to go.
Calcium is better absorbed when taken with food. Also, when you split the dose—1 tablet twice a day rather than all at once---the calcium has an even better chance of being absorbed. And, we added vitamin D to our formulation to further help with absorption.
While calcium is important at all stages of life, Kirkland Signature Calcium 600 mg with Vitamin D3 is intended for adults.
Recommended Daily Allowances (RDA) for calcium were established by the Institute of Medicine (IOM) based on age and gender. Men between 19-70 years old require 1,000 mg calcium daily, whereas men over 71 years need 1,200 mg per day.
Women between the ages of 19-50 years old need 1,000 mg calcium per day and those over 50 years old need 1,200 mg per day. The Tolerable Upper Intake Level (UL) of calcium for men and women older than 18 years of age is 2,500 mg per day.
Rich sources of calcium include dairy products, such as cheese, milk, and yogurt. Leafy greens, like kale, broccoli, and spinach also provide calcium in moderate amounts, but they contain other elements that may block calcium absorption.
Oxalic acid or oxalate strongly inhibits calcium absorption and can be found in spinach and rhubarb. Foods fortified with calcium include fruit juices, tofu, and cereals.
Vitamin D is a fat-soluble vitamin that is naturally available in a few foods but it is added to other foods. One way to get Vitamin D is through exposure to sunlight. Vitamin D is produced by the body when ultraviolet rays of the sun hit the skin and signal its production. However, the use of sunscreens could block the absorption of Vitamin D.
