What Does It Mean to Have No Moons on Fingernails?

Moons are actually a half-moon in shape. They are located on the base of your fingernails. Typically, it is believed that having no moons or small moons means that you either have an under-active thyroid gland or low blood pressure.

Researchers have found that no moons on your fingernails may mean that you are deficient in vitamin B12 or iodine. Normally, a lack of vitamin B12 can cause memory problems, depression, a loss of coordination or a lack of energy. Iodine is needed by your thyroid gland, so you may have thyroid problems. A lack of iodine is also connected to breast cancer. If you are deficient in one of these nutrients, it is important to have your levels checked early to prevent other health problems.

Researchers have also found that no moons or smaller moons are linked to carbon monoxide exposure. If this is the problem, it is important to make sure to use a ventilation system when you are in traffic. You should also make sure to stay at least 20 feet from any running vehicle to prevent carbon monoxide exposure.

If you are deficient in vitamin B12, there are other signs that you may have a deficiency. Other than having no moons on fingernails, you may notice symptoms like:
