Why Your Calcium is Causing Constipation (+ What to Do About it!)
Does Calcium Cause Constipation?
Unfortunately, most calcium supplements cause constipation and other gastrointestinal issues like bloating, gas, and cramps! Chances are you’re reading this because you’ve had a bad experience with these issues.
Beyond the discomfort, these gastrointestinal issues are a big problem because they can keep you from taking your recommended dosage of calcium every day. Why would you want to feel sick to your stomach, right?
After reading this post, you’ll know how to avoid all these problems and not have to worry about missing your dosing schedule.
Why Do Calcium Supplements Cause Constipation?
Watch the video below or read the transcript here as Lara Pizzorno, Bone Health Expert dives in further to this common question. And don’t forget to continue reading for more insight not in the video.
Most calcium supplements cause constipation because they supply only calcium or just calcium and vitamin D. It takes a variety of nutrients for proper absorption of calcium, especially magnesium. Magnesium is a natural laxative and thus counterbalances the constipating effects of calcium.
If your calcium supplement and/or your diet lack magnesium then constipation can occur. But with enough magnesium, your colon walls will relax helping you pass stool along. Additionally, magnesium attracts water, meaning more water gets to your colon and softens your stool.
On the flip-side, calcium contracts muscles. If you’re getting too much calcium the muscle walls of your colon contract, making it harder to pass stool. The longer your stool sits in the colon, the more water is pulled out of it. This makes the stool dense and hard, making it significantly harder to pass and likely painful.
Magnesium reduces tension on the walls of your colon which allows for a normal peristaltic action. Peristaltic action, also known as peristalsis, means “a radially symmetrical contraction and relaxation of muscles which propagates in a wave down the muscular tube”. This means the rhythmic movement of your intestinal tract that moves food from one end to the other.
Regularly including magnesium-rich foods in your diet is great for overall health, plus it will keep you regular.
9 Causes of Constipation and What to Do About it

#1 Too Much Supplemental Rock Calcium: The most common type of calcium and the one that causes the most gastrointestinal discomfort is from rock. That’s right – your supplement is most likely calcium derived from limestone or marble (described on your label as ‘calcium from calcium carbonate’).
Why do we eat rock calcium (and since the 1930s when it was first introduced)?
Because rocks are cheap, rich in calcium (40%) and capable of slowing bone loss.
See, we naturally lose about 1% of our bone per year after age 35. For decades, rocky calcium carbonate has cut that in half so we only lost about 0.5% per year. Given no other calcium (from shell, coral or cattle bone) could boast anything more, slowing bone loss with rock calcium was better than not slowing it at all.
But a very uncomfortable side effect of rock calcium carbonate that we’ve tried to accept is constipation, as well other gastrointestinal issues like bloating, gas, and cramps. These gastro issues happen because rock calcium carbonate essentially turns off the production of stomach acids.
This is why rock is used as the main component in antacids like Tums. It works great if you suffer from acid reflux and heartburn – but your digestive system pays the price! If stomach acids aren’t there to churn and break down your food, then it makes sense that constipation, bloating, gas, and cramps will result.
Plus, taking too much calcium alone at once provides more calcium than the body can absorb, leading to constipation. For this reason, it is recommended to take no more than 500 mg of calcium at a time. After all, calcium is a mineral, and minerals are rocks. So even though it’s an important nutrient your body needs, you’re essentially asking your body to absorb a rock. Be kind and patient with your body by taking amounts that your body can tolerate, absorb and utilize.
Solution: Choose a well-absorbed form of calcium in a dosage of 500 mg or less. Calcium is absorbed most efficiently when it’s taken in amounts of 500 mg or less at one time. However, it’s also important to not supplement with calcium alone, which we’ll get into down at point #9.
#2 Too Much Supplemental Iron: Iron supplements are notorious for causing constipation and that is why many people don’t follow through with their supplementation. While there are some forms of iron that are easier to absorb, they tend to come at a higher cost.
Solution: Speak with your healthcare provider about supplementation options. If you have clinical iron deficiency anemia, your health care provider can write a prescription for an iron supplement that may be easier to digest and is covered by insurance. Additionally, ask to speak with a nutrition professional about how to get your iron from foods.
#3 Too Much Sugar and Unhealthy Fats: Consuming too much sugar and/or unhealthy fats feeds unhealthy bacteria in your gut and causes inflammation. The unhealthy bacteria start to multiply and this reduces the healthy number of bacteria that keep the digestive tract moving properly. Inflammation can then occur and trigger a whole host of problems in the body. This means the intestinal tract can swell with inflammation, making it difficult for food to move through it.
Solution: Reduce or eliminate foods with added sugar and refined carbohydrates. The same goes for unhealthy fats. Avoid fried foods as much as possible, which also tend to contain refined carbohydrates. Also, swap out unhealthy fats for naturally-occurring healthy fats that have a soothing, inflammation-reducing effect. These can be found in plant-based oils, seeds, nuts and fatty fish. AlgaeCal’s Triple Power Omega 3 Fish Oil is perfect for helping you reduce inflammation and transition over to healthy fats.
#4 Lack of Physical Activity: If you ever undergo a medical procedure or end up in the hospital, one of the first things the medical team will do to get you on the mend is help you go for a walk. That’s because we are designed to be on the move and our digestion depends on it. Walking helps move and jostle the food in the digestive tract, using gravity to help move it along. Yoga, jogging, Pilates, and the like will all have the same benefits. They also help strengthen your muscles, including the intestinal tract, giving you greater ability to move things both inside and outside your body.
Solution: Get up and get moving as often as possible. Take a walk after meals and try to take a couple 5-to-10 minute walking breaks during the work day. Prolonged periods of sitting are bad for digestion, mood, and overall health.
#5 Lack of Fiber: Ever eat too many cherries or too much watermelon and find yourself having to make a quick escape to the bathroom? That’s because these fruits are high in flavor and fiber. You get caught up in the delicious flavor, only to find yourself in the bathroom with diarrhea a couple hours later from all the fiber. Take it easy.
If you’re not eating a fiber-rich diet, you have the exact opposite problem. Fiber is a key component in the human digestive tract. Fiber binds to water, which softens the stool, making it easier to pass along. Additionally, fiber and the water that it attracts creates “bulk”, which sends a message to the intestinal walls that you’re full and it’s time to get to work passing the food along. In this way, fiber helps with both digestion and weight regulation.
Solution: Slowly increase the amount of fiber you eat each day. Going from next-to-zero grams of fiber to the full recommendation of 20 to 25 grams all at once is going to cause diarrhea. Spread fiber intake out throughout the day to get the benefits without the downside. Strive for 5 grams every meal and snack.
#6 Imbalanced Gut Bacteria: We all get by with a little help from our friends, including the healthy bacteria that make digestion and proper nutrition possible. Healthy bacteria help break down food to extract maximum nutrition and keep it moving along. Certain medications, stress and not eating enough fiber-rich foods can have negative effects on your gastrointestinal bacteria.
Solution: Gut bacteria thrive on foods naturally rich in fiber, such as fruits, vegetables, legumes, nuts and whole grains. Consume probiotic (healthy bacteria) foods and beverages such as kefir, yogurt, kimchi, sauerkraut, kombucha and homemade shrubs. Take a probiotic supplement. If you’re currently taking antibiotic medication, take your probiotic supplement at a different time or you’ll cancel the effects of both.
#7 Certain Medications: A common side effect of several medications is constipation. Always read the information that comes with your medications to see if constipation is a common side effect. The list of medications that can cause constipation is lengthy, but some of the top offenders are opioids, NSAIDs, antihistamines, antacids, blood pressure medications and diuretics.
Solution: Follow your healthcare provider’s instructions relating to your medications, but reach out to get more information and solutions regarding constipation. Discuss the duration you’re expected to be on the medication and ask if there are easier-to-digest alternatives. Eat a healthy, fiber-rich diet full of fruits, vegetables, seeds, nuts, legumes and whole grains. Additionally, exercise regularly, drink plenty of water and get plenty of sleep.
#8 Lack of Water: Water has been mentioned frequently throughout this article and that’s because it’s vital for healthy digestion. Dehydration wreaks havoc on the human body, including the digestive tract. When you’re dehydrated, your body will conserve as much water as possible for cerebral fluid, blood volume, and respiration.
Solution: Drink 8 to 10 glasses of water every day. All fluids count in fluid consumption, but not all beverages are created equal. Avoid sugary drinks and/or those with toxic food additives. Limit caffeine consumption to 2 to 3 cups of caffeinated beverages a day or under the 400 mg mark.
#9 Lack of Magnesium: Magnesium is needed to relax muscles, including those of the gastrointestinal tract. Magnesium is also an electrolyte that affects water balance. Low magnesium intake causes a host of health problems, including constipation. It is also needed to properly absorb and utilize calcium. It is estimated that 80% of Americans are deficient in magnesium.
Solution: Makes sure to eat a variety of magnesium-rich foods such as dark leafy green vegetables, seeds, nuts and beans throughout the day, every day. Keep in mind that calcium and magnesium work together. The proper ratio is 2:1 (2 parts calcium to every part magnesium) so make sure you find a calcium supplement with the same ratio. AlgaeCal Plus naturally contains this 2:1 “golden ratio”.
While all of the above solutions can help ease constipation issues, you’ll still have problems if you take a calcium supplement with calcium alone or with added vitamin D. Consider switching supplementing with a higher quality calcium. Not doing so puts you at risk for constipation and other health-related issues. It’s not worth it to save money by taking what you have on hand.
As you’ve now learned, magnesium is a natural laxative- which will balance the constipating effects of calcium- and also has bone-building properties. Make sure your calcium supplement contains magnesium to prevent constipation, provide bone health benefits, as well as maintain water balance.
Instead of masking the problems from your current calcium supplement, try a natural, plant-based calcium supplement providing you with all the nutrients your bones need. Plus, you won’t have side-effects like constipation, gas or bloating!
AlgaeCal Plus is the only calcium supplement proven to increase bone density in 6 months— at any age! It’s the plant-based solution, meaning it’s more body-friendly, plus it’s more effective at a lower dose than your typical calcium supplement.
How to Choose The Best Calcium (That Doesn’t Cause Constipation)
When looking at calcium supplements, consider these factors:
There are several things to consider when purchasing a calcium supplement. Running out to the store and buying the cheapest one you see can actually do you more harm than good. Not only can that supplement cause painful constipation, it can cause other health issues and end up being one more thing cluttering up your cabinets.
Consider the following points before putting your money towards a calcium supplement: Take a look at why you want to take a calcium supplement; how much you have to spend on the supplement; how frequently you’ll have to purchase more; the dosage; physical size of the supplement (one of the biggest reasons people stop taking supplements is difficulty swallowing them); and product form– liquid, tablet, capsule, powder, etc. Do your research to see what clinical studies, guarantees, certifications and measures for clean, ethical sourcing the company has.
- True Cost: If your calcium supplement is just calcium alone or calcium and vitamin D it is not enough. Your bones are made up of much more than that! They need magnesium, vitamin K2, D3, C, boron, and trace minerals. Buying all of those separately is expensive and a hassle. Instead, get an all-in-one bone formula.
- Amount of Calcium: Remember that your body can only absorb 500 mg of calcium at a time, anything beyond that will make you feel sick to your stomach and lead to constipation. In addition to constipation, too much calcium at once or over time has potential health risks like calcium depositing into soft tissues and kidney stones. AlgaeCal Plus is more effective at a lower dose, compared to higher amounts in other calcium supplements. Plus, it contains the mighty mineral called vitamin K2, which directs calcium straight to your bones and keeps it out of your arteries!
- Supplement Size & Form: Tablets, capsules, chews, oh my! Can you physically swallow the supplement? Interestingly, one of the top reasons people stop taking a pill or supplement is because it’s hard to swallow because of its size. AlgaeCal Plus is placed in veggie capsules that you can pull apart if you find swallowing difficult. There are also calcium “chews” on the market. Those tend to be laden with food dyes, artificial flavors, and added sugars… all things you don’t want, nor need a supplement.
- Clinically Proven: Do the research to see if the supplement company has done their research. Do they openly share clinical trials proving the safety and efficacy of their product on their website? Is that information easily accessible to the public?
- Quality: There are an overwhelming amount of supplements on the market these days and it’s up to the consumer to do their research. While time-consuming, it’s important to know what you are putting in your body. Read up on the supplement company to see what certifications, research and ethical sourcing efforts they have put into their product. Also, check to see if they are certified organic.
The Bottom Line: All Calcium is NOT Created Equally
Constipation is an unwelcome side-effect. But don’t lose sight of why you started taking a calcium supplement in the first place – bone health. More than likely you started taking calcium to stop bone loss, but did you ever think your calcium supplement could increase your bone density too?
That’s why at AlgaeCal we looked for a way to not only stop bone loss but build bone mineral density too. Plus, we wanted to end the digestion problems from rock-based calcium. Turns out, the answer was floating off pristine South American shorelines this whole time – a bone-friendly, plant-based calcium. In fact, it’s the most mineral-concentrated plant on earth, containing all 73 trace minerals naturally found in your bones right now.
What’s more, the minerals are “predigested” by the plant making them more body-friendly!
That’s why you won’t have any upset stomach or constipation from this rare marine algae. AlgaeCal Plus is the only calcium supplement that has been shown to increase your bone density naturally, without side-effects.
Even better, you can take it with the only mineral known to promote bone growth and inhibit bone loss at the same time. This bone-building duo is unmatched by any other supplement or nutrient combination you can find.
