The dangers of calcium injections

In order to balance the elements in their body, many people will take medicine to solve the problem. They will take the corresponding artificial synthetic elements, such as calcium tablets, if they lack certain elements. However, this process takes a long time. Because of this, many people will choose calcium injections. Calcium injections can quickly balance the calcium in their bodies. But in fact, calcium injections have great disadvantages for the human body. You can learn about the dangers of calcium injections through the following article.

Why calcium injections are not advisable

Calcium supplementation through calcium injections is not a method worth adopting. Because intravenous injection of calcium supplements will cause a substantial increase in blood calcium concentration in a short period of time, the human body will secrete a large amount of calcitonin at this time. In addition to some calcium being excreted in the urine (which can easily cause urinary tract stones), the rest will be abnormally transferred: part of it is sent to the bones, and is mainly deposited in parts of the bone joints that are subject to greater force, such as the lumbar vertebrae, cervical vertebrae, knee joints, heels, etc., leading to bone hyperplasia in these parts; part of the calcium is deposited in the blood vessels, causing vascular calcification, which will cause cardiovascular disease over time.

How to supplement calcium safely, correctly and effectively?

The first thing is how to supplement calcium safely.

1. Damage caused by taking extra calcium supplements such as calcium tablets and calcium agents:

First of all, it should be made clear that calcium supplementation is not safe for everyone in all circumstances, and calcium supplementation should not be done blindly. Researchers from the Johns Hopkins University School of Medicine have found that extra calcium supplements may increase the risk of arterial plaque buildup and heart damage.

The researchers analyzed the test results of more than 2,700 participants over a decade and divided them into five groups. After adjusting for multiple factors such as age, gender, and race, the researchers found that the group with the highest total calcium intake had a 27% higher risk of heart disease than the group with the lowest calcium intake. The researchers then analyzed the differences between two groups of people, one group that only consumed calcium from the diet and the other group that took additional calcium through calcium supplements. The results showed that the latter group had a 22% higher risk of coronary artery calcification than the former group.

2. High calcium diet/dietary calcium supplementation is safe:

So do all forms of calcium supplementation lead to an increased risk of the above diseases? The researchers believe that a high-calcium diet is safe and that the body responds differently to calcium in the diet and in supplements, because participants who had the highest daily calcium intake did not have an increased risk of heart disease. In addition, one researcher also believes that a high-calcium diet not only has no adverse effects on the heart, but may even have a protective effect. So according to the results of this study, the way of calcium supplementation is very important.

It is recommended that if you are not calcium deficient but want to supplement calcium, you should try to do so through food rather than taking calcium tablets or calcium supplements.

The second is how to supplement calcium correctly.

If the body is indeed deficient in calcium and under the guidance of a doctor, calcium tablets and calcium supplements can be used to supplement it:

So does this mean that all calcium tablets and calcium supplements are no longer viable? That is not the case. The above research was aimed at studying additional calcium supplementation for normal people, that is, people who do not have a calcium deficiency or the deficiency is not much. However, for many children due to dietary deviations and physical development needs, pregnant women due to physical nutritional needs, and middle-aged and elderly people with physical diseases such as osteoporosis, they can still supplement calcium through calcium tablets and medicines. However, if you want to supplement calcium through the above methods, it is best to go to the hospital for a physical examination and take calcium supplements under the guidance of a doctor. Otherwise, a large amount of additional calcium supplements will not only be of no benefit to the body but will also have side effects, which will not be worth the cost.

Again, how to supplement calcium effectively.

1. Can the calcium in calcium tablets be directly absorbed by the human body?

In fact, the calcium in calcium tablets cannot be directly absorbed by the human body. If you want it to be truly utilized by the human body, it must have a carrier, and this carrier is vitamin D. In other words, if there is no vitamin D, even if you take a large amount of calcium tablets or calcium supplements, they cannot be directly used and absorbed by the human body, and the ideal calcium supplement effect cannot be achieved at all.

2. What is Vitamin D?

Vitamin D is a steroid derivative that has anti-rickets effects and is also called anti-rickets vitamin. The most important members of the vitamin D family are D2 and D3. Vitamin D is a derivative of different vitamin D precursors after ultraviolet irradiation. Plants do not contain vitamin D, but provitamin D exists in both animals and plants. The ergosterol in plants is provitamin D2, which can be converted into vitamin D2 after ultraviolet irradiation, also known as ergocalciferol; the 7-dehydrocholesterol contained subcutaneously in humans and animals is provitamin D3, which can be converted into vitamin D3 after ultraviolet irradiation, also known as cholecalciferol.

3. How can vitamin D be obtained?

The first way - sunshine:

The human body's subcutaneous steroid substances can form vitamin D after being exposed to ultraviolet rays, so you can choose to bask in the sun at noon on a sunny day. Generally, 15 to 20 minutes of sunlight exposure to the face and hands can meet the body's daily vitamin D needs.

This is a very simple method, so it is recommended that you go out for a walk with your family, friends, and children on a sunny day. Not only will your mood become brighter, but it can also promote the body's calcium absorption and prevent diseases. It doesn't cost any money, so why not do it!

The second way - obtain from food:

Although this is also a way, it is still very difficult to obtain it from food because there are very few foods rich in vitamin D. Except for marine fish (cod liver oil, sardines, herring, salmon, tuna), milk and dairy products, human natural food contains very little vitamin D. Because most vitamin D is synthesized in the body, only a small amount of vitamin D3 comes from food.

The third way - supplementation:

With the changes of the times, people have realized the important role of vitamin D in calcium absorption, so various efforts have been made on vitamin D. For example, cod liver oil is made from the livers of marine fish, infant and mother formula milk is fortified with D2 or D3, and various types of milk are also specially fortified with vitamins A and D.

Since most people nowadays spend most of their time working in high-rise buildings and don’t like to go out, most people do not have enough vitamin D in their bodies, so supplementing vitamin D through supplements is also a very good choice.

Final summary:

Through the above explanations, I believe everyone has a full understanding of how to supplement calcium safely, correctly and effectively. Therefore, in future calcium supplementation, you must base it on your own physical condition and not supplement calcium blindly. If you are not calcium deficient but want to supplement calcium, you can do so through dietary supplements. In order to better absorb calcium, you can choose to get more sun exposure, increase vitamin D supplements, or eat foods such as marine fish to assist. Of course, when buying calcium tablets, you can also choose those with added vitamin D.
