What is Calcium Citrate?
Calcium is the most abundant mineral in the human body and is essential for several biological processes,
including cellular signaling, mitochondrial function, blood clotting, muscle contraction, and nerve impulse
transmission. Its most well-known purposes are to build and maintain strong bones and teeth. Calcium can
also bind to other minerals and assist in eliminating them from the body.
Calcium citrate is a calcium salt derived from citric acid. It is one of the most bioavailable forms of
calcium available on the market, equal to that of calcium carbonate. However, calcium citrate supplements
don’t interact with stomach acid, making them easier to absorb than calcium carbonate supplements. Beyond
its use as a dietary supplement, the food and beverage industries use calcium citrate as a sour flavoring
additive and food preservative. It also has use as a water softener because the citrate can chelate unwanted
Calcium Deficiency Symptoms
Dairy products and dairy-fortified foods account for 72% of dietary calcium intake in the United States. The
richest calcium foods include milk, yogurt, and various kinds of cheese. As a result, individuals with
lactose intolerance or those following a vegan or vegetarian diet may struggle to consume adequate calcium
from their diets. Low levels of vitamin D can also contribute to calcium deficiencies. Postmenopausal women
and the elderly also have an increased risk of calcium insufficiency.
The body needs calcium to sustain itself, and it will leach it from bones and teeth to obtain it if
necessary. Deficiency symptoms become more prominent the longer the body goes without adequate calcium
intake. The following are several calcium deficiency symptoms:
- Nails that break easily
- Bones that fracture easily
- Slowed hair growth
- Fragile, thin skin
- Muscle spasms and cramps
- Numbness or tingling in hands and feet
- Confusion or memory problems
Potential Calcium Benefits
Calcium for Bones
Numerous scientific studies have proven calcium’s role in developing and maintaining healthy bones. The FDA
also recognizes this fact and requires all food labels to include their calcium contents. Calcium
supplements are particularly important for older adults, as hormonal changes can lead to bone wastage and
mineral loss from bone tissue. Calcium supplements are even more effective for older adults when paired with
vitamin D. The body needs vitamin D to absorb calcium. It also reduces bone loss and the risk of fractures
in the elderly population.
What is the Best Calcium Supplement?
PureBulk carries numerous calcium supplements. Which one is best depends on the individual’s needs. For
example, calcium citrate is best for older adults and individuals with insufficient stomach acid. Calcium carbonate
is another highly
bioavailable calcium supplement. PureBulk also offers coral calcium
, which provides calcium
carbonate and magnesium.
Calcium Citrate with Vitamin D
helps the body absorb
calcium and also plays a role in strengthening muscles.
Calcium and Magnesium
Calcium works with magnesium to sustain
bone health. Most individuals need a 2:1 ratio of calcium to magnesium for optimal results.
Older adults, individuals with diabetes, and individuals with malabsorptive conditions have a greater
risk of developing magnesium and calcium deficiencies.
How to Take Calcium Supplements for Best Absorption
Most calcium supplements require acid to break them down. However, calcium citrate is the one exception. The
body absorbs the calcium from calcium citrate supplements equally well with or without food. Calcium citrate
supplements are the superior option for individuals taking proton-pump inhibitors and older adults, as they
naturally have lower stomach acid levels. Calcium citrate supplements are also better for bariatric bypass
patients that received gastric bypass surgery, as it’s easier for their altered anatomy to absorb.
How Much Calcium Per Day?
Calcium supplements work best when taken throughout the day. Although most adults need 1000mg of calcium per
day, they should not take more than 600mg of calcium at a time. Calcium needs change with age and certain
medical conditions. For example, pregnant and lactating women need 1300mg of calcium per day. Women over the
age of 50 and all adults over the age of 70 need 1200mg per day.
