B12 and Fingernails

This is a fingernail, Obviously.

What is equally visible but not as obvious is that the person has health issues.

In 400 B.C.E. Hippocrates, father of clinical medicine, said fingernails reveal health and inner condition. Hippocrates was the first to identify clubbing, where a fingernail bends over, as a sign of lung and heart disease.

More common than lung and heart disease are issues related to nerves and/or blood.

Fingernail ridges and faint moons coincide with health problems involving balance, numbness, depression, memory decline, or in other words, symptoms of low vitamin B12.

Every six months you have a new fingernail. The rate of growth from cuticle to tip is about an eighth inch a month. As a result your fingernails are constantly giving you an updated view of your nerve and blood health.

Good vitamin B12 levels produce white moons at the base of each fingernail. When levels are low, the thumb’s moon is last to go. (Tessa Jupp, R.N., active in the Post-Polio Network, Dec. 2001).

If your moons have disappeared you may be noticing many of the following:

Other Symptoms of Low B12 & Malabsorption

  • tingling hands and feet
  • numbness
  • memory problems
  • feeling exhausted
  • depression
  • sensitivity to noise
  • lots of brown spots
  • bleeding gums
  • burning sensation (possibly on thighs)
  • legs hurt and “jump” at night
  • pain, including bone pain in legs
  • balance and gait problems
  • heavy menstrual bleeding or nose bleeds
  • diarrhea
  • a more complete list of symptoms

With or without moons, you may have ridges develop on your nails. These can be faint, to very visible, even lines on top of lines that look like hogback hills. To see them clearly use a magnifying glass or reading glasses.

If you have faint, hardly noticeable lines, you are likely to have only a few symptoms of low vitamin B12. If you do nothing other symptoms will follow. If you take action, however, you can reverse most early damage from low vitamin B12 levels.

Blue skin under your fingernails indicates a shortness of red blood cells and by extension the oxygen they carry.

Low vitamin B12 may affect blood, nerves, or both. It’s not the same for everyone. What is the same is that red blood cells are supposed to divide. For many people a stomach disorder causes B12 malabsorption. If you can’t absorb vitamin B12 your red blood cells are affected by the low B12 levels and become large instead of dividing. When red blood cells no longer fit into tiny blood vessels you begin to experience numbness.

Methylcobalamin relieves symptoms

The form of B12 your body needs and uses is Methylcobalamin. If you give your body cyanocobalamin, it will make methylcobalamin.

Methylcobalamin Lozenges 1000 mcg.

Vitamin B12 is safe because your body excretes what it doesn’t use. You needn’t worry that Methylcobalamin will hurt you. As a point of reference, I used five to ten 5 mg. Methylcobalamin lozenges each day for over 5 years before the cobalamin built up enough to cause muscle spasms/cramping.

As soon as I began taking Cilantro capsules to bind B12’s cobalt, the spasms diminished in frequency till they went away. B12’s name, cobalamin, derives from cobalt, the essential trace element it contains. B12 is the only vitamin containing a metal.

Before using Methylcobalamin I used Cyanocobalamin which has some cyanide in it. The Cyanocobalamin caused a brown spot in my field of vision. I say it caused it because the brown spot went away when I switched to Methylcobalamin.

Be aware that genuine healing may result in painful muscle spasms if your potassium levels are beneath what your blood cells need once they begin properly dividing. There are many potassium rich foods you can eat to end muscle spasms as blood cells resume normal activity.

Potassium is essential ~ Read more.

If you need B12 and use Methylcobalamin, your health will improve within two months. Significantly. I know from experience. If you keep notes, you will more easily be able to see what has changed. But, without doubt B12 will help. (This is like Stravinsky who said, “Inspiration is never wrong. If it turns out to be wrong, it wasn’t an inspiration.” (And, though true, I put the quote here to amuse you.)

B12/Methylcobalamin lozenges work even if you have B12 malabsorption illness, which is increasingly common in people who are under stress and/or take antacids or some other medications. Lozenges work because the B12 is absorbed directly through the membrane under your tongue.

Pictures show fingernail lines in the texture of the nail. They also show moons in various stages of return and retreat. Because changes in nail texture are gradual you may hardly notice them at first. When you see ridges in your nails check a list of symptoms of low B12; then, if you are dealing with some of the symptoms use Methylcobalamin and track your improvement using a Time Line.

Fingernail white spots

White spots can appear suddenly on fingernails. They often appear in relation to extreme stress and may be accompanied by a “sick” feeling, to include feverishness, that lasts for days or even weeks.  View Pictures.

    This is very informative. My b12 was 41 and I’ve now brought it up to 331 and even though my doctor says this is normal now I still have ridged nails and no moons. Also hair loss by the hand fulls. I thought by bringing my b12 to 331 my nails would look great again and my hair loss would stop by now. I am hypothyroid and on thyroid meds but my thyroid levels are now normal so I don’t think it’s my thyroid causing the hair loss. Should b12 be at a certain level to stop hair loss?

    Hi Ruth,

    Thank you for your comment.

    41 is a VERY low B12 level. If that level was determined by a blood test, which is most likely, then the B12 in your deep tissue, where it is vital, was even lower.

    The information on what B12 level is considered “normal” in other countries is interesting: https://health-boundaries.com/what-is-a-healthy-b12-level/

    It’s interesting to me that you mentioned your hair falling out. I’ve only recently noticed that very little of mine is falling out at this point, even though I let my B12 levels slip last winter.

    My experience with hair loss showed that it was worst when I had an active infection around a dental implant. Vitamin C curbed the infection efficiently, stopping the pain and the swelling. But, the infection remained. I have to keep using C.

    Then I learned about Astaxanthin. I now use that every day because it helps significantly with joint pain. It actually stopped a grinding noise that came from my hips when I moved. Here’s the page I did on Astaxanthin Health Benefits: https://health-boundaries.com/astaxanthin/

    I was lucky to have gone at one point to a holistic M.D. with a background from Sweden, I think it was. I forget exactly which country. Anyway, the use of B12 injections there was far more common than here in the U.S. She said she liked to keep her patients’ levels at 1200.

    She gave me a prescription for a shot a day, which I was sure was a mistake. It was for 12 bottles of injectable cyanocobalamin, each containing 30 shots worth. So I didn’t use it for a long time. But then when I had tetanus and she wouldn’t see me b/c I didn’t have any money, I got the prescription filled and began using a shot a day.

    To my surprise the extremely painful peripheral neuropathy which other doctors had all told me was Permanent Nerve Damage, went away.

    At this point I used Methylcobalamin lozenges. I have to use 5 or 6 of the 5mg ones a day to equal a B12 shot a day. And they have to be some time apart b/c our bodies can only use 8 mg a hour. Any more and it’s excreted.

    I hope this helps.
