Our Yearly Guide


Calcium and osteoporosis are closely linked, and if you have a calcium deficiency, your bones will be the ones to suffer. Thankfully there is a straightforward solution for this in the form of calcium supplements. The downside is that since the market is flooded with so many options to choose from, people often end up getting more confused in the process.

We want to simplify the entire process for you, which is why we have compiled the following buyer’s guide that will go through the key aspects one should consider when purchasing calcium for osteoporosis.

How much calcium do you need?

The amount of calcium that you should get from a supplement depends on how much of it you are already getting from your diet. Men over 70 and women over 50 require 1,200 mg per day while an adult needs 1,000 mg. Before you decide to get a supplement, it is best to check with your doctor to know exactly how much you need.

Another thing to remember that if, for example, you need to get 1,000 mg of calcium per day from supplements, you can’t take it all at once since the more calcium you take, the more difficult it will be for your body to process it all. This is why it is recommended to take smaller amounts at each meal throughout your day until you reach the desired total.

Make sure that you don’t go over your recommended daily amount since if you go overboard, your body will have to get rid of it through the kidneys which will raise the risk of kidney stones as well as hardened blood vessels and tissue.


Types of calcium

There are two types of calcium that you are likely to find in supplements, and the more common of the two is calcium carbonate. If your tablets contain the carbonate variety, you will need to eat something when you take it because this type needs to react with the acid in your stomach for the best results.

The other type available is calcium citrate, and we found that customers who have a hectic schedule tend to like this option more since it is possible to take it on an empty stomach.

Why vitamin D is important

Vitamin D gets produced by your body when sunlight hits your skin, and very few people get enough of it through natural means. It is also possible to get it from some foods such as fish, egg yolks, cheese, and certain foods that have added vitamin D such as juice, cereal, or milk.

The reason why vitamin D is so essential to help you fight osteoporosis has to do with the fact that your intestines absorb the calcium from the foods you eat with the help of vitamin D. This is the reason why you will find that most calcium supplements on the market include just enough vitamin D in each tablet to help your body absorb all the minerals.


Should I worry about side effects?

While we can’t say for certain if you will encounter a side effect when taking a particular type of calcium supplement, there are a few things you can do to protect yourself. In case you know you are allergic to certain ingredients, you should take the time to read the entire list since some options may get the calcium from natural sources such as grains.

When switching to a new type of calcium supplement, you should start with a small daily dose of 200-300 mg for around a week and build it up gradually since this way if you experience a side effect, it won’t affect you as much. Some of the side effects you can experience are gas, constipation, and bloating.
