Calcium supplementation?


Hello Dr.
Chen, I would like to ask if drinking milk is an effective way to supplement the calcium needed by the body? I consume about 950cc of milk daily, and I wonder if this habit of drinking milk like water is beneficial for my health.
Additionally, if I take calcium supplements on top of drinking milk, could this lead to excessive calcium intake? Furthermore, I sometimes experience diarrhea after drinking milk; do you have any suggestions for improvement? Thank you for your time, Dr.
Chen!

Dear Kipo: Milk is rich in calcium, which is very important for bone health.
Based on your age, the recommended daily intake of calcium is 1000 mg.
Research shows that the average daily calcium intake in Taiwan is about 400-500 mg, which is significantly below the recommended amount.
One cubic centimeter of milk contains approximately 1 mg of calcium, so your daily calcium intake is about 1500 mg.
As long as there are no specific health issues, this amount is acceptable, but it is best to spread the intake throughout the day and avoid consuming more than 500-600 mg of calcium at one time to prevent interference with calcium absorption.
It is preferable to obtain calcium from daily food sources; calcium supplements should only be considered if dietary intake is insufficient.
There are many types of calcium supplements, and since each person's health condition is different, it is best to discuss which type and dosage of calcium supplement is appropriate with a physician.
It is quite common for Asians to have lactose intolerance or milk allergies; in such cases, low-lactose milk, calcium supplements, or other high-calcium foods such as tofu, soy milk, small fish, dark green vegetables, and sesame can be used as alternatives.
In addition to adequate calcium intake, bone health also requires a balanced diet, regular exercise, a consistent lifestyle, avoiding smoking, limiting alcohol consumption, reducing excessive coffee intake, and getting some sunlight.
Attached is a table of the recommended daily calcium intake and the calcium content in various foods for your reference.

More Info


Drinking milk is often considered a primary source of calcium, which is essential for maintaining strong bones and overall health. The recommended daily intake of calcium varies by age and gender, but for most adults, it is around 1,000 mg per day, increasing to 1,200 mg for women over 50 and men over 70. A typical serving of milk (about 240 cc or 8 ounces) contains approximately 300 mg of calcium. Therefore, consuming 950 cc of milk daily can provide a substantial amount of calcium, potentially meeting or exceeding the daily requirement for many individuals.

However, relying solely on milk for calcium supplementation may not be sufficient for everyone. While milk is a rich source of calcium, it is also important to consider other dietary sources of calcium, such as leafy greens (like kale and broccoli), fortified foods (like orange juice and cereals), nuts, seeds, and fish with bones (like sardines). A varied diet ensures that you receive not only calcium but also other essential nutrients that work synergistically for optimal health.

Regarding your question about taking calcium supplements in addition to drinking milk, it is crucial to be cautious about the total calcium intake. The upper limit for calcium intake is generally set at 2,500 mg per day for adults. If you are consuming a significant amount of milk and also taking calcium supplements, you could potentially exceed this limit, which may lead to health issues such as kidney stones or impaired absorption of other minerals. It is advisable to consult with a healthcare provider or a registered dietitian to assess your total calcium intake and determine if supplementation is necessary.

If you experience diarrhea after consuming milk, it may indicate lactose intolerance, a common condition where the body lacks the enzyme lactase needed to digest lactose, the sugar found in milk. Symptoms of lactose intolerance can include bloating, gas, and diarrhea after consuming dairy products. If this is the case, you might consider switching to lactose-free milk or dairy alternatives fortified with calcium, such as almond milk, soy milk, or oat milk. These alternatives can provide calcium without the discomfort associated with lactose.

In summary, while drinking milk can significantly contribute to your calcium intake, it is essential to maintain a balanced diet that includes a variety of calcium sources. Be mindful of your total calcium intake from both food and supplements, and consider your body's response to dairy products. If you have concerns about lactose intolerance or calcium supplementation, consulting with a healthcare professional can provide personalized guidance tailored to your specific health needs.
