Some decades ago I read a book about a very proper woman, who maintained that each nail on a well-groomed hand should have a perfect half moon at the base. Not to have them indicated you were some sort of cultural slacker.
I thought ‘is this some crazy habit like having your purse match your shoes?’– or perhaps a genetic anomaly, like twinsets, duck boots, pearls and Lilly Pulitzer?
But then I thought I’d try to achieve those half moons.
Much as I worked at it, I couldn’t. Orange sticks, cuticle cream, professional manicures, daily pushing back of cuticles. All I got was sore cuticles.
Thumb good, forefinger, OK, middle finger, a tiny glimpse of white, ring and pinkie, nada.
So, the other day, I noticed the moons are back, at least visible on thumb and first three fingers, and just a sliver on the pinkie.
This is one of those tiny clues to health.
Do the last thirds of your eyebrows peter out as they get closer to your temples? – Check your thyroid levels.
Are your gums pale? Check your iron.
Fingernails are a virtual encyclopedia for health problems: dry and chalky, fragile and splitting, showing ridges and deformities, flecked with white spots . . . so what about the moons?
Disappearing moons can signify a deficiency in B vitamins, particularly B12.
If you, like me, have a MTHFR mutation in your genetic structure (easily found in a blood test) you can take certain B vitamins, including B12, until the cows come home and see no benefit– UNLESS you buy them in a methylated form. Otherwise, your body can’t absorb them.
Sufferers of Celiac can be highly deficient in B vitamins, and years of undiagnosed Celiac, is what, I believe led to my eclipsed lunula, the proper name for the half moons on fingernails.
I take biotin by the wheelbarrow, which has led to much better looking nails, healthy color, strong and shiny, and also take a B complex. I hadn’t noticed, but my lunula, half moons, are much more pronounced than they ever have been during my adulthood. Methylated B vitamins are no more expensive than non-methylated: you simply need to read the label. Look for the prefix “methyl-” in the B12 and Folate/folic acid lines.
No more polish or chemicals on my nails. Just a light buffing, and they look properly groomed enough for me.
Maybe I’ll buy a twinset next.
I have my eyes on these beautiful Navajo pearls from IsaStone at Etsy:
I do draw the line at duck boots.

Great information! My girlfriend suffers from celiac disease and has experienced the nail issues. Your information came along just at the right time.
Thank you Jim! I’m glad it was helpful. May your glutenfreebelle have better fingernail days ahead.
