However, this effect was only significant at high caffeine intakes (above 300mg per day).

Another study published in the American Journal of Clinical Nutrition found that moderate caffeine consumption (200-300mg per day) had no significant impact on calcium absorption in postmenopausal women.

Chlorogenic Acid and Calcium Metabolism

Chlorogenic acid, a polyphenol found in coffee, has been shown to affect calcium metabolism. Research suggests that chlorogenic acid may increase calcium excretion in the urine, potentially leading to decreased calcium levels in the body. However, this effect is still speculative and requires further investigation.

Coffee Consumption and Bone Health

While the relationship between coffee and calcium levels is complex, research has also explored the impact of coffee consumption on bone health. Some studies have found that moderate coffee consumption may actually have a positive effect on bone density:

• A study published in the Journal of Agricultural and Food Chemistry found that moderate coffee consumption (3-4 cups per day) increased bone density in older adults.
• Another study published in the Journal of Bone and Mineral Research found that coffee consumption was associated with higher bone mineral density in postmenopausal women.

However, it’s essential to note that these findings are not universal and may depend on various factors, such as age, sex, and overall diet.
