Final answer:
Individuals advised to consume calcium supplements should consume 2)1000 mg per day.
Step-by-step explanation:
The amount of calcium an individual should consume daily varies based on age, gender, and physiological conditions. For adults over 18, the requirement is 800 mg/day, while during lactation and in the pregnancy of the 2nd and 3rd term, it increases to 1.2 gm/day. Infants under one year require between 360-540 mg/day, and children from 1 to 18 years need 800-1200 mg/day. Considering these guidelines, adults generally advised to take calcium supplements should consume 1000 mg per day. This amount ensures adequate calcium intake for most adults, barring specific medical conditions that might warrant a different dosage.
Vitamin D plays a critical role in the absorption of calcium, promoting its uptake in the upper small intestine. Acidic pH and certain dietary components like organic acids, lactose, and basic amino acids also support better calcium absorption. Calcium-rich foods include dairy products like milk and cheese, and it's essential to balance your diet to enable efficient absorption and utilization of calcium. For the prevention of conditions such as osteoporosis, maintaining a diet high in calcium, complemented by vitamin D, is essential. The answer is option 2.
