Get More from Your Calcium Supplement
How to maximize calcium absorption
by Michelle Gibeault Traub, R.D.
Calcium
is a very important nutrient. It is essential for the health of your bones,
teeth, nerves, muscles, and much more. With all that it does it isn’t too
surprising that daily calcium needs can range from 800 to 1300 mg depending on
your age*. But, there are lots of complicating factors in meeting those high
calcium requirements every single day! With a little know-how, you can get the
most from your daily calcium intake.
Calcium Helpers
In order to
maximize calcium absorption and also keep calcium in the bones, your body needs
help from other nutrients and certain conditions including:
- Vitamin D – Calcium’s best friend, vitamin D
helps the body to absorb calcium. Therefore, it is very important to consume
the two nutrients together. Most calcium supplements, including Adora Calcium
contain vitamin D. But, some high calcium foods do not, particularly some
fortified foods and vegetables like broccoli and spinach. To remedy this problem,
be sure to get more D through supplements or sun exposure.
-
Vitamin K – K is best know for its role in
clotting the blood, but it also helps keep calcium in the bones. The digestive
tract is able to make adequate amounts of vitamin K, but some calcium
supplements, like Adora Calcium, include the nutrient to optimize bone health.
-
Magnesium – Calcium’s cousin, magnesium is a mineral that actually helps maintain calcium levels in the body. Magnesium
can be found in a wide variety of unprocessed foods such as nuts, seeds, whole
grains, and leafy grains.
-
Stomach Acid – Calcium is absorbed into the blood
stream in the upper portion of the small intestine. However, before this can
occur, calcium must be broken down by stomach acid. Ideally, calcium pills should be taken with food to
stimulate stomach acid production. Since Adora Calcium is chewable and
contains real chocolate, it is likely that the stomach will produce enough acid
for adequate digestion, but for those who have digestive trouble it is wise to
eat a little snack with your Adora Calcium supplement to insure optimal
absorption.
-
Timing & Amount – Digestion is a slow and steady
process which takes approximately 2-3 hours to complete. However, during that
window of time the body can only absorb approximately 500 mg of calcium. As a
result, in order to meet requirements of 1000 mg or more, you must consume at
least 2 servings of calcium either from supplements or through foods spread out
over the course of 2 to 3 hour intervals. For
example:
A cup of yogurt at
10:00 a.m. (300 mg of calcium) +
An Adora Calcium at
2:00 p.m. (500 mg of calcium) +
An Adora Calcium at 7:00 p.m. (500 mg
calcium) = 1300 mg
This fulfills the calcium requirements (1300 mg) of a
teenager or postmenopausal woman (See Chart Below).
Naturally,
calcium’s “helpers” can’t do their job if you aren’t getting enough of the
mineral to begin with. Take a look at the Calcium Resources below for the
number of Adora Calcium supplements, and the types of calcium-rich foods that
will help you meet your daily calcium requirements. With a little planning, you
can easily give your body the calcium it needs.
While Calcium has a
great group of friends, it unfortunately has lots of enemies too. Watch for
next month’s Women’s “circle of health” where we address “Calcium Challenges:
Factors that fight calcium absorption”.
