Do You Need to Supplement Calcium?
Generally, I don't recommend supplementation with calcium.
Calcium can easily be obtained through a healthy diet.
This is true regardless of whether the person is an omnivore, vegetarian, or vegan.
Supplementation poses risks.
In order for calcium to be properly used by the body such as incorporated into our bones, it must be taken with other minerals such as magnesium.
Calcium, taken in isolation, without the necessary co-nutrients, can lead to it being unabsorbed and this can cause it to accumulate toxicity in the body.
We all know that excess calcium can cause kidney stones.
Excess calcium can also cause many other health problems in our bodies when not taken appropriately and in the right ratio with other nutrients.
It is stated that more than 40% of the US population (with 70% of older women) take calcium supplements. Less than half of that calcium is absorbed in the gut; he rest is either excreted through the large intestine, causing constipation, or through the kidneys, potentially forming kidney stones. Or it is transported to other soft tissues, where it can harden (calcify) into gallstones, heel spurs, atherosclerotic plaques, fibromyalgic calcifications, and breast tissue calcifications.
Therefore, taking in excess calcium by taking supplements is a great risk and can cause many health problems, including plaque buildup in blood vessels and calcifications in various parts of the body.
Since calcium can easily be obtained through a healthy, natural diet, it makes more sense to do it this way.
