Calcium, vitamin D, and nutrition for women

Calcium is important for women of all ages. It has been shown to help alleviate PMS symptoms, support a healthy pregnancy, and prevent osteoporosis and bone loss after menopause.

Calcium is absorbed slowly; your body cannot take in more than 500 mg at once. Also, calcium from naturally occurring sources is absorbed better than calcium supplements.

Women under the age of 40 need 1,000 mg of calcium daily. After age 40, you need between 1200-1500 mg a day. To boost your calcium intake:

* Start your day with a calcium-fortified whole grain cereal and low-fat milk.
* Choose high calcium snacks such as yogurt, calcium-fortified orange juice, canned sardines with bones, and almonds.
* Pick hard cheese over soft. An ounce of cheddar packs 200 mg, versus a meager 60 mg in a half-cup of cottage cheese.
* Understand food labels. If a label says a serving supplies 25% of daily calcium, simply add a 0 to the percentage to decipher how many mg are in that serving. In this case there are 250mg which is 50% of 500mg, the maximum amount the body can absorb at one time.

Many health conditions can affect calcium levels. Be sure to talk with your doctor about your calcium requirements and whether you need a bone density evaluation.

Calcium can’t work alone – for your body to utilize and absorb the calcium you need Vitamin D and magnesium as well. You can get Vitamin D from direct exposure to sunlight, and also from foods like fortified milk, egg yolks, saltwater fish, liver and supplements. According to the National Osteoporosis Foundation, adults under age 50 need 400-800 IU of vitamin D3 daily (the best form of vitamin D for bone health), and adults over 50 need 800-1,000 IU of vitamin D3 daily. Magnesium is usually found in green vegetables, nuts and legumes, and you should aim for about 320/mg per day.
