Whenever taking calcium supplements, it is important to supplement magnesium as well. Magnesium balances calcium and ensures that it does not get deposited in the cell tissues ad other places such as the pineal gland. Magnesium is very important.
The issue here with calcium rich foods, Dairy is the most calcium rich food accessible. Dairy is fit for consumption especially when raw or fermented, like with kefir and yogurt. Milk from pastured animals eating healthy green grass is the most healthy. Grass fed dairy that is raw is even safe and digestible for those with lactose problems.
If one is relying on plant sources for calcium you must keep in mind that our soils are depleted due to over working and industrial farming, Taking from the land and not giving back. This means that are crops are lacking in nutritional density and minerals. If there are minute amounts of minerals, such as calcium, in our soils, what do you expect to get from the plants? So best to opt for healthy dairy.
To ensure you get your efficient mineral content, grow your own crops or use a supplement. A good one.
