My fingernails have become more and more soft and brittle and they split all the time. I've been on B12 for 7 years.
Hi Peggy-sue,
Obviously the presence or lack of something is causing lack of cell formation. Based on decades of debugging B12 and folate therapies these listed below make a decent checklist of why they don't work. I discovered early on that with each factor left to chance fewer than 5% would succeed with actually healing. My nails suddenly got thicker though it took some while for the newly formed parts to show up above the cuticle. Good luck.
THE 95% REASONS B12 AND FOLATE THERAPIES FAIL
Version 2.0 - 03/10/11, Version 2.1 - 05/08/11. Version 3.0 – 10/25/2012, Version 3.1 10/26/2012, Version 11/05/2012 3.2
1) They take an inactive b12, either cyanob12 or hydroxyb12. The research validating their use was primarily for reducing blood cell size in Pernicious Anemia, keeping the serum b12 level over 300pg/ml at the end of the period between injections. They make a statistically significant effect that can be seen in lab tests in a significant percentage of people compared to placebo. They do not heal most damage done by active b12 deficiencies and have little or no effect on the vast majority of symptoms. They may even block active b12 from receptor sites hindering the
effects of real b12. They both cause a keyhole effect of having only a very limited amount (estimated at 10-30mcg/day) that can actually be bound and converted to active forms. They in no way increase the level of unbound active cobalamins which appear required for most healing. They do nothing beneficial in a substantial percentage of people (20-40%) while giving the illusion that the problem is being treated and if it doesn’t work, oh well, that’s the accepted therapy. There is no dose proportionate healing with these inactive b12s because it all has to go through this keyhole. Some people are totally incapable of converting these to active forms because they lack the enzymes or ATP
2) They take active b12 as an oral tablet reducing absorption to below 1%. A 1000mcg active b12 oral tablet might bind as much as 10mcg of b12. Again the b12 has to be squeezed through a keyhole that limits the amount and is subject to binding problems in the person whether genetic or acquired.3. They take a sublingual tablet of active b12 and chew it or slurp it down quickly reducing absorption back to that same 1% and limited to binding capacity. With sublingual tablets absorption is proportionate to time in contact with tissues. I performed a series of absorption tests comparing sublingual absorption to injection via hypersensitive response and urine colorimetry.
3) Of the many brands of sublingual methylb12 only some are very effective. Some are completely ineffective and some have a little effect.
4) For injectable methylb12, if it is exposed to too much light (very little light actually is too much) it breaks down. Broken down methylb12 is hydroxyb12. It doesn’t work at healing brain/cord problems of those who have a presumed low CSF cobalamin level. That requires a flood of unbound methylb12 and adenosylb12 (2 separate deficiencies) that can enter by diffusion. Adenosylb12 from sublinguals can ride along with injected methylb12.
5) They don’t take BOTH active b12s.
6) They don’t take enough active b12s for the purpose.
7) Lack of methylfolate
8) Lack of sufficient Methylfolate, a dose can start more healing than the same dose can complete.
9) Paradoxical Folate Deficiency - Folic acid is taken which can block at least 10 times as much methylfolate from being active inducing folate deficiency even if methylfolate is also taken. These induced deficiency symptoms are often called "detox" symptoms. Folinic acid is taken which can block at least 10-20 times as much methylfolate from being active inducing folate deficiency even if methylfolate is also taken. These induced deficiency symptoms are often called "detox" symptoms.
10) Lack of l-carnitine fumarate (rarely ALCAR), the 4th of the Deadlock Quartet
11) Lack of other critical cofactors.
12) Lack of basic cofactors
13) Glutathione, glutathione direct precursors, NAC and /or whey is taken causing what is often called "detox" while actually being induced folate and b12 deficiencies.
14) Having many additional supplements and herbs of unknown interactions and effects.
