Is calcium dangerous to take every day? Yes! Certainly! Taking too much calcium, easily from calcium products, can cause hypercalcemia, many calcium in the blood. Here are some other examples of conditions that lead to hypercalcemia.

Causes of hypercalcemia 

1. Certain diseases and medicines: Conditions like chronic kidney disease can reduce the kidneys’ ability to excrete calcium, leading to its buildup in the blood. And medications for treatments of hyperparathyroidism or cancers may increase calcium levels in the blood. Conditions like these can stimulate bones to release more calcium into the bloodstream. Drugs, such as thiazide diuretics, can increase blood calcium levels, too. 
2. Vitamin D toxicity. High levels of vitamin D can increase absorption levels for calcium intake from the GI tract.
3. Overuse of calcium supplements: Easy to guess! Excessive intake of calcium or vitamin D supplements can lead to hypercalcemia. Taking more than recommended is a direct cause of hypercalcemia

What are the symptoms?
Hypercalcemia can have various effects on our bodies, ranging from mild to severe symptoms.

1. Effects on the heart and blood vessels. Cacium is a essential mineral to control blood pressure. But increased condition may raise pressure due to its effects on contriction of the blood vessels. And also, calcium has an electrical activity and play a crucial role in the heart beat. But hypercalemia can cause irrefular hearbeats, and on an ECG, it can cause a shortening of the QT interval, reflecting changes in the cardioelectrical system.
2. Renal dysfunction. A little bit more serious than GI troubles. Kidney stones formed by high levels of calcium and oxalate cause harmful conditions for overall health. Interfering functions of the kidney may cause frequent urination due to uncontrollable urinary system. The worst is kidney failure; severe hypercalcemia can cause nephrocalcinosis (calcium deposition in the kidneys). This directly damages kidney organs and is a great risk factor of kidney failure.
3. GI troubles. Gastrointestinal symptoms such as nausea and vomitting, abdominal pain and constipation are usual. Excess calcium intake can ruin a normal functioning of gut and motility. Perhaps it is a simple sign to quit calcium in daily lifestyles.
4. Effects on skeleltal and muscular system. High levels of calcium for a long time cna weaken bones and result in reduced bone denstity. Generally elevated calcium weaken the muscle and its neurological system. You may feel impaired muscle function and fatigue, too.

Tips for preventing hypercalcemia
To avoid these symptoms, need to focus on recommended calcium dosages. Stick to the RDA, which varies by age and sex. For the average adult, 1,000 mg per day is recommended, and women may take up to 1,200 mg if ages over 50. Balanced diet will be the best. Get calcium from a combination of dietary sources. A well-calcium-balanced diet and regular checks are necessary if you are already at risk of hypercalcemia. Monitoring vitamin D intake may help to control the levels. Increasing fluid simply by drinking enough water can dilute calcium in the blood and help to excrete excessive amount throughout the kidneys. Medications like bisphosphonates, calcitonin, and corticosteroids can be used, but you need a prescription first. In severe cases, hemodialysis may help. 

Oxalate-containing foods

For the preveting renal stones, oxalate intake should be controlled. There are some examples avoiding or limiting for clean kidney.

1. high-oxalate foods. Much high oxaltes in some foods are risky for hypercalcemic conditions. Spinach is the most famous in this categories, and beet greens and many other green vegetables are high in calcium levels. Beets, okra, and sweet potatoes needed to be avoided. Nuts like almonds and cashews are also containg high levels of oxalates. Among friuts, berries such as rasberries and blackberries have a lot more than other berreis. Soy products and brown rice should be considered, too.
2. Low-oxalate foods. Then what are oxalate-limited foods? Kale and collard greens are valuable in leafy greens family. They have lower oxalates compared to spinach and other vegetables. Cabbages, cauliflower, and zucchini do contains fewer or lower oxalates. Fruits! Bananas and melon are good choices. And dairy products and eggs will help.

By focusing on these lower-oxalate alternatives and adjusting your diet accordingly, you can effectively manage your oxalate intake and reduce the risk of kidney stones and other related health issues.

Abstract
Taking calcium every day can lead to hypercalcemia. It can also happen if patients with poor kidneys or if they take certain drugs, and high vitamin D intake can also increase the amount of calcium in the body, which can lead to hypercalcemia.
When hypercalcemia occurs, blood pressure problems and irregular heart beats can be fatal to healthy lifestyles. A steady intake of high calcium can cause various health problems due to calcium deposits in the kidneys.
To prevent these symptoms in advance, on average, you can take up to 1,000 mg per day for an average adult, and a little more, 1,200 mg (50>) for a woman. Also, try to control your vitamin D intake.
Spinach, beets, nuts, sweet potatoes, and brown rice, which are high in oxalic acid, should also be careful to prevent kidney stones. On the contrary, cabbage, zucchini, mushrooms, onions, and white rice, which are low in content, are recommended.
