Is Calcium Chloride Safe To Eat In Food

12

Calcium is an essential nutrient found in many foods, such as dairy products. The bones and teeth contain over 99% of all calcium in the human body.

Bones are always breaking down and rebuilding. Calcium is needed for this process, but the concentration of calcium in the body tends to decline with age. Taking extra calcium helps the bones rebuild and stay strong. The heart, nerves, and blood-clotting systems also need calcium.

People commonly take calcium by mouth for the treatment and prevention of low calcium levels, muscle cramps, osteoporosis, softening of the bones, and PMS. It is also used for high blood pressure, cancer, stroke, and many other conditions, but there is no good scientific evidence to support many of these other uses.

In the US and Canada, foods that contain calcium and vitamin D are allowed to state that they might reduce the risk of osteoporosis.

Uses & Effectiveness ?

Effective for

  • Indigestion (dyspepsia). Taking calcium carbonate by mouth as an antacid is effective for treating indigestion.
  • High levels of potassium in the blood (hyperkalemia). Giving calcium gluconate by IV can reverse heart problems caused by high potassium levels. IV products can only be given by a healthcare provider.
  • Low levels of calcium in the blood (hypocalcemia). Taking calcium by mouth and by IV is effective for treating and preventing low calcium levels. IV products can only be given by a healthcare provider.
  • Kidney failure. Taking calcium carbonate or calcium acetate by mouth is effective for controlling high phosphate levels in the blood in people with kidney failure. Taking calcium by mouth also seems to help reduce blood pressure in people with kidney failure.

Likely Effective for

    • Bone loss in people taking drugs called corticosteroids. Taking calcium and vitamin D by mouth seems to reduce bone density loss in people using corticosteroid drugs long-term.
 
  • Overactive parathyroid (hyperparathyroidism). Taking calcium by mouth reduces parathyroid hormone levels in people with kidney failure and parathyroid hormone levels that are too high.
  • Weak and brittle bones (osteoporosis). Consuming adequate amounts of calcium, both from the diet and supplements, is effective for preventing bone loss and treating osteoporosis. Taking calcium by mouth, alone or with vitamin D, also helps prevent fractures in people with osteoporosis.
  • Premenstrual syndrome (PMS). Consuming adequate amounts of calcium, both from the diet and supplements, seems to significantly reduce mood swings, bloating, food cravings, and pain.

Possibly Effective for

  • Colon cancer, rectal cancer. Taking calcium supplements by mouth or increasing intake from the diet seems to reduces the risk of colorectal cancer. But people with low levels of vitamin D don’t seem to benefit from calcium supplements, nor do people who are overweight or obese.
  • Increasing bone strength in the unborn baby. Taking calcium supplements by mouth during pregnancy increases the bone mineral density of the baby when calcium intake from the diet is low.
  • High blood pressure. Taking calcium supplements by mouth seems to reduce blood pressure by a small amount in people with or without high blood pressure.
  • Softening of the bones (osteomalacia). Taking calcium by mouth seems to help reverse softening of the bones caused by very low calcium intake.
  • A pregnancy complication marked by high blood pressure and protein in the urine (pre-eclampsia). Taking 1-2 grams of calcium by mouth daily seems to reduce the risk of pregnancy-related high blood pressure. It seems to be most helpful in those who are high risk and have low calcium levels.
  • Softening of bones in children, often due to vitamin D deficiency (rickets). Taking calcium by mouth seems to help reverse softening of the bones in children with very low calcium intake.
  • Preventing tooth loss (tooth retention). Taking calcium and vitamin D by mouth appears to help prevent tooth loss in older people.

  • Breast cancer. Taking calcium by mouth doesn’t reduce the risk for breast cancer.
  • Fractures. Taking calcium by mouth, alone or with vitamin D, doesn’t seem to prevent fractures in older people who do not have osteoporosis.
  • Heart attack. Taking calcium supplements by mouth doesn’t seem to help prevent a heart attack. In fact, taking calcium supplements by mouth without vitamin D might increase the risk for a heart attack.
  • Obesity. Taking calcium by mouth doesn’t seem to help with weight loss.
  • Death from any cause. Taking calcium supplements by mouth doesn’t seem to reduce the overall risk of death.
  • Side Effects

    When taken by mouth: Calcium is likely safe when used in recommended amounts of about 1000-1200 mg daily. Calcium can cause some minor side effects such as belching or gas. But calcium is possibly unsafe when taken in doses above the daily tolerable upper intake level (UL). The UL is 2500 mg for adults ages 19-50 years and 2000 mg for adults over 50 years. Taking more than this daily can increase the chance of having serious side effects.

    Special Precautions & Warnings:

    Pregnancy and breast-feeding: Calcium is likely safe when taken by mouth in recommended amounts. But calcium is possibly unsafe when taken by mouth in doses above the daily tolerable upper intake level (UL). The UL is 3000 mg for those under 18 years of age and 2500 mg for those over 18 years of age. Higher doses might increase the risk of seizures in the infant. Be sure to consider total calcium intake from both dietary and supplemental sources of calcium. Avoid taking more than 1000-1200 mg of calcium from supplements daily unless prescribed by your doctor.

    Children: Calcium is likely safe when taken by mouth in recommended amounts. But calcium is possibly unsafe when taken by mouth in doses above the daily tolerable upper intake level (UL). The UL is 1000 mg for those 0-6 months old, 1500 mg for those 6-12 months old, 2500 mg for those 1-8 years old, and 3000 mg for those 9-18 years old. Children should consume enough calcium to meet daily requirements, but should not consume extra calcium.

    Low acid levels in the stomach (achlorhydria): People with low levels of gastric acid absorb less calcium if calcium is taken on an empty stomach. People with low acid levels should take calcium supplements with meals.

    Too much calcium in the blood (as in parathyroid gland disorders and sarcoidosis): Calcium should be avoided if you have a condition that causes high calcium levels. Taking calcium supplements can cause calcium levels to increase even more.

    Kidney disorders: In people with kidney disorders, taking calcium supplements can increase calcium levels too much. Speak with a healthcare provider before taking calcium supplements.

    Smoking: People who smoke absorb less calcium from the stomach and might require calcium supplements.

    Stroke: Taking calcium supplements for 5 or more years might increase the chance of developing dementia in people who have had a stroke. More research is needed to know if calcium supplements should be avoided after a stroke.

    Interactions ?

    Major Interaction

    Do not take this combination

    • Ceftriaxone (Rocephin) interacts with CALCIUM

      Administering intravenous ceftriaxone and calcium together can result in life-threatening damage to the lungs and kidneys. Calcium should not be administered intravenously within 48 hours of intravenous ceftriaxone. This interaction is not a concern when calcium is taken by mouth.

    • Dolutegravir (Tivicay) interacts with CALCIUM

      Taking calcium along with dolutegravir can reduce blood levels of dolutegravir. This might decrease the effects of dolutegravir. To avoid this interaction, dolutegravir should be taken 2 hours before or 6 hours after taking calcium.

    • Elvitegravir (Vitekta) interacts with CALCIUM

      Taking calcium along with elvitegravir can reduce blood levels of elvitegravir. This might decrease the effects of elvitegravir. To avoid this interaction, elvitegravir should be taken 2 hours before or 2 hours after taking calcium.

    Moderate Interaction

    Be cautious with this combination

      • Antibiotics (Quinolone antibiotics) interacts with CALCIUM

        Calcium might decrease how well some antibiotics work. In the gut, calcium binds to antibiotics known as “quinolones.” This can decrease the amount of these drugs that the body absorbs. To avoid this interaction, take these drugs at least 2 hours before or 4 to 6 hours after calcium.

      • Antibiotics (Tetracycline antibiotics) interacts with CALCIUM

        Calcium might decrease how well some antibiotics work. In the gut, calcium binds to antibiotics known as “tetracyclines.” This can decrease the amount of these drugs that the body absorbs. To avoid this interaction, take these drugs at least 2 hours before or 4 to 6 hours after calcium.

    • Bisphosphonates interacts with CALCIUM

      Calcium can decrease how much bisphosphonate the body absorbs, which can decrease the effects of bisphosphonates. To avoid this interaction, take bisphosphonates at least 30 minutes before calcium or at a different time of day.

    • Calcipotriene (Dovonex) interacts with CALCIUM

      Calcipotriene is a drug that is similar to vitamin D. Vitamin D helps the body absorb calcium. Taking calcium supplements along with calcipotriene might increase levels of calcium too much.

    • Digoxin (Lanoxin) interacts with CALCIUM

      Calcium can affect your heart. Digoxin is used to help your heart beat stronger. Taking calcium along with digoxin might increase the effects of digoxin and lead to an irregular heartbeat. If you are taking digoxin, talk to your doctor before taking calcium supplements.

    • Diltiazem (Cardizem, others) interacts with CALCIUM

      Taking large amounts of calcium along with diltiazem might decrease the effects of diltiazem.

    • Levothyroxine (Synthroid, others) interacts with CALCIUM

      Calcium can decrease how much levothyroxine the body absorbs. Taking calcium along with levothyroxine might decrease the effects of levothyroxine. Levothyroxine and calcium should be taken at least 4 hours apart.

    • Sotalol (Betapace) interacts with CALCIUM

      Taking calcium with sotalol can decrease how much sotalol the body absorbs. Taking calcium along with sotalol might decrease the effects of sotalol. To avoid this interaction, take calcium at least 2 hours before or 4 hours after taking sotalol.

    • Verapamil (Calan, others) interacts with CALCIUM

      Taking large amounts of calcium along with verapamil might decrease the effects of verapamil.

    • Water pills (Thiazide diuretics) interacts with CALCIUM

      Some “water pills” increase the amount of calcium in the body. Taking large amounts of calcium with some “water pills” might cause there to be too much calcium in the body. This could cause serious side effects, including kidney problems.

    • Aluminum interacts with CALCIUM

      Calcium citrate can increase how much aluminum the body absorbs from aluminum hydroxide. This increase in aluminum levels can cause serious side effects, especially in people with kidney disease. But not all forms of calcium have this effect. Calcium acetate does not appear to increase aluminum levels.

    • Lithium interacts with CALCIUM

      Long-term lithium use can increase calcium levels in the blood. Taking lithium with calcium supplements might increase calcium levels too much.

    • Raltegravir (Isentress) interacts with CALCIUM

      Taking calcium along with raltegravir for several months might reduce blood levels of raltegravir and decrease its effects. Taking a single dose of calcium along with raltegravir does not appear to affect blood levels of raltegravir.

    Minor Interaction

    Be watchful with this combination

    • Medications for high blood pressure (Calcium channel blockers) interacts with CALCIUM

      Calcium channel blockers are a type of medicine used for high blood pressure. Calcium may decrease the effects of calcium channel blockers when given by IV. But taking calcium supplements by mouth or consuming foods containing calcium does not seem to have this effect.
