Osteoporosis and caffeine:
Osteoporosis patients should limit caffeine intake. Osteoporosis occurs due to a decrease of bone mass and quality of bone, which may lead to fracture. In addition to pharmacological options, individuals should also be counseled on the right intake of calcium and vitamin D, increasing weight-bearing exercise, limiting alcohol and caffeine, and avoiding smoking, all of which lessen the symptoms of osteoporosis.

Caffeine adverse reactions and interactions:
As caffeine doses increases, reactions also increase:
As caffeine increased so did the reported risk of indigestion, palpitations, tremor, headache, and sleep difficulty in both men and women. A cross-sectional Australian study of 4558 participants revealed that as the intake of caffeine increased so did the reported risk of indigestion, palpitations, tremor, headache, and sleep difficulty in both men and women. Compared to non-coffee drinkers, men consuming 240 mg of caffeine (about 4-5 cups of coffee or tea) per day were more likely, by a factor of 1.6 times, to experience heart palpitations, 1.3 for tremor, 1.3 for headache and 1.4 for insomnia. In women, the corresponding results were 1.7, 1.5, 1.2, and 1.4. (26)
