What is calcium?

Calcium is a mineral involved in numerous bodily functions, including the maintenance of healthy bones and teeth as well as healthy muscles and nerves.1 For adults, the recommended daily amount of calcium is 700mg.1 It's typically found in food sources such as dairy, fruit, vegetables, nuts and seeds.


What are the benefits of calcium for vegans?

In a traditional diet, most calcium is obtained from dairy sources like milk, yoghurt and cheese. As dairy foods are off limits to people on vegan diets, it may be more difficult to consume the recommended amount of 700mg per day. Additionally, vegan-friendly calcium sources such as spinach, dried fruits, beans, seeds and nuts contain oxalates, and this reduces the amount of calcium your body can absorb from them.1 Therefore, plant-based dairy alternatives fortified in calcium are the best options for vegans.

The main function of calcium in the body is its role in bone and teeth health; approximately 99% of calcium is found in the bone.2 Calcium is required for the growth and maintenance of the skeleton and long-term deficiency in calcium, especially during developmental years, may lead to an increased risk of osteoporosis.3

The remaining calcium in the body is found in the blood, muscle, and other tissue where it plays an important role in muscle contraction, vasodilation and nerve transmission.4
