What time of day is calcium best absorbed?

1. If calcium is supplemented during meals, the body's absorption of calcium will decrease, which will cause waste. Calcium supplementation after meals can better ensure that calcium can be fully utilized. Reminder, milk has the highest calcium content, and the intestinal tract can complete the absorption of calcium 3-5 hours after drinking milk.

2. Research shows. Calcium is excreted in the urine at any time, and urinary calcium mainly comes from the blood. The urinary calcium excreted on an empty stomach after falling asleep at night is almost due to the loss of bone calcium. Therefore, drinking milk before going to bed is the most suitable for calcium supplementation, and drinking milk before going to bed can also improve sleep.

The best time to take calcium tablets in a day is generally before going to bed at night, that is, around 10-12 o'clock. Here's why:

1.Normally, when you sleep at night, especially around 3 a.m., the body will constantly excrete old bone tissue. If the patient takes calcium tablets every day before going to bed, it can ensure that the calcium level in the body is more stable.

2.Because the human body will not eat for a long time when sleeping at night, but urine is formed as usual. In order to maintain normal blood calcium levels, a part of the calcium in the blood is constantly entering the urine, and this part of the calcium is the calcium in the bones.

Calcium supplementation before going to bed can fully provide a calcium source for this calcium regulation at night and block the use of bone calcium in the body.

Although there are many benefits to taking calcium tablets at night, it is important to note that patients with hypercalcemia should not take calcium tablets. This condition is mainly due to the fact that patients with high blood calcium, taking calcium tablets can cause further elevation of blood calcium.

Jiayi: Goodness, beauty. From the idiom: Jia Yan Yi Xing. It means good words and deeds. Suitable for boys and girls to choose names.

Then introduce another method of naming, when taking the name, a word is decomposed into two independent characters, together with the surname to form the name, at first glance it seems to be incomprehensible, do not know the meaning, in fact, as long as the two independent characters that are dismantled are reduced to one, you can suddenly open up, show the true face of Lushan. For example, Lin Baishui, "white water" is decomposed from the word "spring", and the semantics of Lin Baishui are taken from the meaning of "forest spring".

There are a few good time points for calcium supplementation, but they are all separated, and now let's start to elaborate:

1.Half an hour after eating. Fasting calcium is absorbed quickly, resulting in large fluctuations in blood calcium and increased excretion of calcium by the kidneys. The end result is that more calcium is absorbed and more is excreted, which is equivalent to waste.

However, if calcium is supplemented within half an hour after a meal (called "with meal"), the dietary fiber and fat in the food will affect the absorption of calcium, resulting in a decrease in the absorption rate. Therefore, calcium supplementation should be the best half an hour after meals.

2.4-5 hours before bedtime. Human beings excrete more calcium at night, and they cannot be replenished from food at this time, so the human body can only extract calcium from the bones, which will lead to osteoporosis. Therefore, calcium supplementation at night is beneficial to prevent osteoporosis.

However, calcium supplementation before bed can easily cause urinary stones. The reason is that 4-5 hours after calcium intake, the calcium in the blood will reach its peak, and the kidneys excrete calcium at the highest rate.

However, if calcium is supplemented before going to bed, then when the peak period of calcium shooting comes, it is just when you are asleep, and the urine cannot be discharged, resulting in the concentration of calcium ions in the urine getting higher and higher, and finally precipitating in the form of stones.

Therefore, calcium supplementation 4-5 hours before bedtime and urination before bedtime is a healthier way to supplement calcium.

To sum up: if you can ensure that 4-5 hours before bed is exactly half an hour after dinner, then this is the best time to supplement calcium. If not, then leisurely supplement calcium 4-5 hours before bedtime, after all, safety first.

Incidentally, let's teach you the precautions when supplementing calcium:

1.Control the intake of plants high in oxalic acid. Oxalic acid and calcium will form an incompatible calcium oxalate precipitation, if it is good in vitro, it only affects the absorption of calcium, if oxalic acid is absorbed and combined with calcium, it is easy to produce stones.

Foods high in oxalic acid: spinach, water spinach, mustard greens, buckwheat, leeks, bamboo shoots, cocoa, tea, etc.; Foods that contain almost no oxalic acid: cucumbers, pumpkins, watermelons and other melon foods).

2.Control fat intake: Fat and calcium combine to form a soap-like "saponification", which not only affects calcium absorption, but also causes adverse symptoms such as constipation.

3.Control phosphorus intake: For every 2 molecules of phosphorus metabolized by the human body, 1 molecule of calcium is consumed. So a diet high in phosphorus can lead to calcium loss. (Typical foods with high phosphorus: soda, which is high in phosphoric acid).

4.Avoid excessive protein intake: Excessive protein can increase the rate of calcium excretion by the kidneys, leading to calcium loss in the blood.

Hope the above is helpful to you.

1. Calcium supplementation before bedtime

Scientists have found that the best time of day to supplement calcium is every night before bedtime. Calcium supplementation before going to bed can provide sufficient raw materials for calcium metabolism at night, increase the concentration of calcium in the blood, and reduce the occurrence of heart disease, stroke, asthma, emphysema and other diseases. At the same time, the time of day when calcium is most absorbed by bones is at night.

Taking calcium tablets or drinking milk before bedtime, plus 1 or 2 tablets of soda crackers, is a classic strategy for calcium supplementation that is recognized worldwide.

2. Calcium supplementation during the day:

Calcium supplementation during meals will reduce the absorption rate of calcium by the human body and cause waste, while gastric acid is conducive to the degradation and absorption of calcium, so the best time to supplement calcium during the day is about 1 hour after meals.

I think it's better to eat between meals, because at this time the stomach is relatively free, and it is more thorough to drink milk and digest it thoroughly. The same goes for drinking before bed.

The best time of day to take calcium is every night before bedtime. Calcium supplementation before going to bed can provide sufficient raw materials for calcium metabolism at night and increase the concentration of calcium in the blood.

Spring calcium supplementation is the best, because spring is the fastest growing, and so are plants, and spring is the peak period for children to grow taller.

The best time to take calcium is before bedtime and between meals. It is best to rest for half an hour after dinner, because the blood calcium concentration is lowest in the second half of the night and in the morning, which is the best for calcium supplementation.

Tips: Pay attention to two points in the selection: 1 Look at the brand, choose the big brand, ***, the effect is good; 2. Look at the platform, whether the qualifications are complete, whether there is a traceability mechanism, whether it stands with consumers, and the after-sales service is guaranteed.
