Caffeine and bone health -

Human physiological studies and controlled balance studies show a clear but only a very small depressant effect of caffeine itself on intestinal calcium absorption, and no effect on total h urinary calcium excretion.

The epidemiologic studies showing a negative effect may be explained in part by an inverse relationship between consumption of milk and caffeine-containing beverages.

Low calcium intake is clearly linked to skeletal fragility, and it is likely that a high caffeine intake is often a marker for a low calcium intake. The negative effect of caffeine on calcium absorption is small enough to be fully offset by as little as tablespoons of milk.

All of the observations implicating caffeine-containing beverages as a risk factor for osteoporosis have been made in populations consuming substantially less than optimal calcium intakes.

Experts suggest that caffeine interferes with endochondral ossification, a process that remodels cartilage into the new bone with the help of calcium. According to researchers , caffeine also interferes with how the body absorbs calcium from food and can increase how much calcium the kidneys eliminate.

These two mechanisms can lower how much calcium a person has in their body. Caffeine can also interfere with how vitamin D binds to receptors.

As vitamin D helps the gut absorb calcium, this effect can directly influence the amount of calcium in the body. Consuming caffeine can also decrease the levels of inositol — a protein that plays a role in calcium metabolism — in the blood.

With less inositol in the blood, the kidneys eliminate more calcium, and the body absorbs less of it through the intestine. The amount of caffeine that is excessive depends on several factors, with recommendations varying for different people. For example, the American College of Obstetricians and Gynecologists recommends that pregnant people limit their caffeine intake to milligrams mg per day.

In otherwise healthy adults, mg of caffeine is usually safe. There are no guidelines defining a maximum daily limit. The American Academy of Pediatrics does not recommend caffeinated drinks for children and adolescents.

The organization does not mention any effects that caffeine may have on bone growth or bone health during puberty. Researchers are unsure how much caffeine is necessary to lead to negative effects on calcium and osteoporosis. Although studies have explored how caffeine affects calcium metabolism, researchers are unsure whether these effects contribute to osteoporosis.

A study on rats showed that high caffeine consumption decreased bone mass and reduced bone formation. However, animal studies do not always represent what will happen in humans.

An older study examined the effects of coffee drinking in postmenopausal women with fracture osteoporosis. The researchers concluded that coffee consumption was not related to bone tissue turnover, a normal process that involves breaking down and rebuilding new bone tissue. However, the findings suggest that high caffeine consumption may be associated with increased calcium loss.

Due to the link between low calcium and vitamin D intake, this may mean that caffeine is indirectly associated with osteoporosis. To prevent osteoporosis , doctors suggest getting the recommended daily amount of calcium and vitamin D in the diet.

A low calcium diet is a key risk factor for osteoporosis, and substances such as caffeine can mask it. Vitamin D is also important because the body cannot absorb calcium from the intestines without it.

Additional studies using a broad population may help determine the effects of caffeine on osteoporosis. People who get the recommended daily allowance RDA of calcium and vitamin D may counteract the potential negative effects of caffeine.

However, some experts advise that even small quantities of milk can offset the possible risks of caffeine. Adding 1—2 tablespoons of milk to the diet may be enough. Some people have an increased risk of osteoporosis regardless of caffeine consumption.

As a result, the potential negative effects of caffeine may further increase their risk of bone health issues. For example, children and older adults can experience higher rates of bone diseases and may need to limit their caffeine intake.

During puberty, adolescents experience quick growth because of maximal calcium deposition in the bone. However, researchers are still unsure whether caffeine affects bone growth and strength in children and adolescents. It is unclear whether it causes osteoporosis in children because the rates of the condition are very low.

Although many types of tea contain caffeine, some research indicates that tea may actually be good for bone health. According to a study , green tea polyphenols GTP may prevent osteoporosis.

The researchers found that GTPs might improve bone mineral density and slow bone loss. The same study showed increased bone mineral density in older women who drank tea compared with those who did not. However, other research contradicts these findings, reporting that tea had no effect on bone health.

The evidence supporting the effects of drinking tea for preventing osteoporosis is inadequate to confirm its benefits. Caffeine may interfere with how the body absorbs, metabolizes, and eliminates calcium. Disruption of calcium in the body can contribute to certain bone diseases, such as osteoporosis, but it is unclear whether the effects of caffeine on calcium are significant enough to cause osteoporosis.

Experts suggest limiting caffeine to avoid side effects such as trouble sleeping, increased blood pressure, and emotional issues.

Researchers are still working to understand the effects of caffeine on osteoporosis and bone health in different age groups. Caffeine is a stimulant that occurs naturally in several foods. Some companies also add it artificially to their drinks and snacks.

Investigating the effects Caffeine and bone health coffee Electrolyte Deficiency how the kidneys Garcinia cambogia side effects calcium in the body, researchers found Electrolyte Deficiency high doses Caffelne caffeine mg consumed over a six-hour period almost doubled the amount of calcium lost in the urine. This is the first study to report the impact of high-dose, short-term caffeine intake on renal clearance of calcium, sodium, and creatinine in healthy adults. Osteoporosis is a chronic, painful, and debilitating disease which makes your bones less dense and more susceptible to fracture. More common in women, it occurs when bones lose calcium and other minerals faster than the body can replace them. In Australia, an estimatedpeople have osteoporosis. The double-blind clinical study saw participants chew caffeine or a placebo gum for five minutes at two-hour intervals over a six-hour treatment period total caffeine mg. Caffeine is a regular Health and environmental impact assessment of the diet of hralth adults coffee, tea, soft drinks, snd energy drinks. Multiple Caffrine effects of Quality weight loss suggest that Caffeine and bone health may promote bone loss. The most Caffeine and bone health pharmacological Cafeine of caffeine is non-specific antagonism Caffeie adenosine receptors. Adenosine regulates bone metabolism in a complex manner, with in vitro studies suggesting that direct stimulation of adenosine A 2A and A 2B receptors induces bone formation by activating osteoblasts and suppressing osteoclast differentiation and function. Thus, competitive inhibition of adenosine A 2 receptors by caffeine may inhibit bone formation and promote bone resorption. However, antagonism of adenosine A 1 receptors may have opposing effects. Caffeine has also been suggested to affect bone through derangement of calcium metabolism, alteration of vitamin D responses, and other mechanisms.
