You can eat calcium-rich foods such as bok choy, kale, mustard greens, turnip greens, watercress, chickpeas, and tofu that have been calcium-set. Vegans can increase their calcium intake by consuming fortified plant milk and juice.    Calcium is recommended in the RDA for most adults at 1,000 milligrams per day and at 1,200 milligrams per day for adults over 50  Due to the absence of meat, vegans may have slightly lower daily requirements. There is no scientific evidence to support either claim. Studies indicate that vegans consuming less than 525 milligrams of calcium daily are at an increased risk of fractured bones. Therefore, vegans should consume at least 525 mg of calcium per day.
