Calcium & Nails: Debunking the Myth

[Smachine]

Hi!

I have heard this many times, even from quit educated people, that lack of calcium causes brittle nails. I know that nails contain protein - keratin, not calcium. And even if the body lacked calcium resorption from bones would first happen? So I don't see how it can cause brittle nails, but I have heard it so many times and so many people have claimed that it helps. So is this really a myth or there is some truth in it?

It would appear CNN agrees with you.

"...the belief that calcium helps nail growth is widespread, presumably because nails contain calcium, the element that keeps bones strong. However, bones have 800 times more calcium than nails.

The new results "provide no support for the idea that calcium intake alters self-reported nail quality ..."

Thank you for bringing up this topic. I can confidently say that the idea that lack of calcium causes brittle nails is indeed a myth. Nails are primarily made up of a protein called keratin, which is also found in hair and skin. Calcium plays a role in maintaining strong bones, but it is not a significant component of nails.

Brittle nails can be caused by a variety of factors, such as frequent exposure to water or harsh chemicals, nutritional deficiencies, and underlying health conditions. However, there is no scientific evidence to suggest that calcium deficiency is a direct cause of brittle nails.

In fact, as you mentioned, if the body lacks calcium, it will first be taken from the bones to maintain the necessary levels in the blood. This process is tightly regulated by the body's hormones and does not affect the calcium levels in other parts of the body, such as nails.

It is important to note that while calcium may not directly affect nail health, it is still essential for overall bone health and should not be ignored. Eating a balanced diet that includes calcium-rich foods, such as dairy products, leafy greens, and fish, is important for maintaining strong bones.

In conclusion, the idea that lack of calcium causes brittle nails is a myth. Nails are primarily made of protein, not calcium, and other factors such as nutrition and lifestyle habits play a more significant role in nail health. It is always best to consult a healthcare professional for any concerns about nail health or overall nutrition.
