What Are the Benefits of Calcium for Women?
Typically, we think of calcium as only benefiting our bone health. Most of us know that calcium is the major mineral in our skeleton (in fact, the average woman houses 2.6 lbs of calcium in her skeleton), but we don’t often stop to think about why. Yes, calcium provides structure and strength to bone, but it also acts as a “functional reserve,” storing calcium in the bone so it’s available for other bodily functions.
We often think of bones as static and unchanging, but that’s actually not the right way to think about them. Bones are actively remodeling, building up and breaking down every day. And when dietary calcium is inadequate, the body pulls the calcium stored in our bones to keep other vital systems running.
How Does Calcium Support Muscle Contractions?
First, calcium is used by the body to support muscle contractions. As A.G. Szent-Györgyi explains in his 1975 article on the “Calcium Regulation of Muscle Contraction,” calcium is essential for muscle contraction because it allows actin and myosin, the proteins responsible for movement, to interact. In the absence of calcium, regulatory proteins block this interaction, preventing contraction. When calcium binds to these regulatory systems, it triggers structural changes that enable muscles to contract and function properly. This is also why calcium and magnesium work together so closely, since both minerals play a role in how muscles fire and recover.
What Role Does Calcium Play in Nerve Function?
Another key role of calcium is nerve function. Calcium helps signals move through your body by acting as the trigger that allows nerve cells to communicate. When an electrical signal reaches the end of a nerve, calcium enters the cell and causes the release of neurotransmitters, which are the chemical messengers that pass the signal to the next cell. This is part of why women with low calcium levels often experience muscle cramps, tingling, and fatigue, because the nervous system simply cannot communicate the way it should.
Why Is Calcium Important for Heart Health?
Calcium is also very important to how the heart works, linking electrical signals to the actual pumping action of each heartbeat. When calcium enters heart muscle cells, it helps trigger contraction, and when it is removed, the heart relaxes and refills with blood.
Simply put, calcium is what allows the heart to beat in a coordinated, rhythmic way, and without it, the heart would not be able to pump blood effectively. This is one of the less talked-about benefits of calcium for women, but it is obviously essential.
How Do Calcium Needs Change During and After Menopause?
Now let’s zoom out and think about calcium from a lifespan perspective. Calcium matters at every stage of a woman’s life, but it becomes especially important during and after menopause. One of the biggest shifts women experience is the loss of estrogen, a hormone that helps protect bone. This is why HRT (hormone replacement therapy) is FDA-approved for osteoporosis prevention, and it’s why many women see a sharp decline in bone density during the menopausal transition, with as much as 20% loss in bone mineral density in the 5 to 7 years following menopause.
We also get less efficient at processing and utilizing calcium as we age. After age 50, the goal is about 1,200 mg of calcium a day, up from 1,000 mg during younger adulthood. Most women are not getting enough calcium, with many getting only around 800 to 900 mg a day from food. That gap matters, especially after menopause when bone loss speeds up. Even how and when you take calcium can affect how much your body actually absorbs, so the details matter.
Are Most Women Getting Enough Calcium?
Knowing what we know now about just how important calcium is to our everyday function, allowing our heart to beat, muscles to contract, and nerves to function, is good motivation to pay attention to our calcium consumption. It’s also worth knowing that not all supplements are created equal. Conventional calcium supplements are made from synthetic forms that are harder for the body to absorb and are known to cause bloating and constipation, which is one of the reasons so many women stop taking them consistently.
It’s helpful to think about why we need this much calcium every day so we can better commit to eating a calcium-rich diet, but even so, many women still don’t consume enough. Seen Nutrition’s Calcium Chew Complete was designed to solve that. Each chew provides 500 mg of calcium from milk minerals. We formulated it to taste good and be easy to stick with for years, which is what matters most.
