Why B12 & Folinic Acid for Down syndrome?

Studies suggest that an inadequate amount of vitamin B12 may be a risk factor for brain atrophy (shrinking) and possible cognitive impairment. Studies also show that individuals with Down syndrome commonly have low levels of B12 and Folic/Folinic Acid (or folate). In one study, typical seniors who took B12 supplements did a better job of holding cognitive declines at bay than placebo. Since the brain of a person with DS has similar qualities of a brain of an elderly person, we need to pay attention to studies about seniors. Supplementing with B12 and Folinic Acid also helps to normalize metabolism. 

Folic/Folinic Acid (or folate) is particularly important within our population since it is needed for the synthesis of DNA and RNA, which are the building blocks of cells. They also help prevent changes to the DNA that could lead to cancer such as leukemia, which our population is particularly susceptible to. It is also needed in both children and adults to be able to make normal red blood cells and prevent anemia. Specifically, B12 and Folinic Acid are used in a metabolic cycle called the SAM cycle.
 
Please visit Changing Minds Foundation's page on B12 and Down syndrome for more details.

Dr. Oz recently did a great show on B12, not specific to T21, but a nice overview: http://www.doctoroz.com/episode/americas-b12-deficiency 

Types of Folic Acid, Folinic Acid and Folates

Folic acid, actually, should be avoided in the DS population, those with the MTHFR variation (much more common in the DS and autism population and in mothers of children with DS) and older moms who want to have children. See   How to Prevent DS in Your Next Child in 60% of Moms for details as to why folic acid is difficult to process and properly use in our bodies. For this population, folic acid should be avoided in enriched foods such as breads and cereal as well.

Folinic acid also known as Calcium Folinate has been shown to have positive effects on children with DS whether or not they have the MTHFR variation.

Folate is a broad term, it may refer to Calcium Folinate, "naturally occuring folate" which may be folinic acid or could be a form of l-5-methylfolate. If it's not clear on the label, I'd contact the company to make sure of the source. 

Calcium Folinate has been shown to have positive effects on children with DS whether or not they have the MTHFR variation. It's not recommended for the typical population who has the MTHFR variation.

L-5-MTHFR, l-5-methyltetrahydrofolate, 5-methylfolate, etc. is the folate of choice for those with the MTHFR variation. (This is what I take. Jett has both DS and MTHFR so I give him both, just in case. Hopefully I'll eventually learn which is best but I'm covering my bases.)

B12

Different children need different forms of B12. If your child has one or more of the MTHRF mutation, the methylcobalamin is preferable (40% of the typical population has this mutation. Jett does). With some kids, if you give the full dose the first day, it causes hyperactivity. If you see this happening, reduce the dose and slowly increase each day until you reach the full dose. If problems still occur with methylcobalamin, look into the hydoxocobalamin form (see healthy awareness article below).

B12 can be difficult to metabolize so you don't want to give it in food or have them shallow it. Instead, buy sublingual drops or mouth or nose spray or other easy to assimilate form. It also needs to be taken on an empty stomach, 
first thing in the morning works well. If your child still has low levels of B12, you can look into the B12 shots (watch out for extra ingredients in the shot, however).

Methylcobalamin B12 

B12 drops
This is what I use for myself. I just put the drops under my tongue first thing in the morning and try not to swallow, rather allow it to dissolve in my mouth.

B12 spray
This is what I use for Jett first thing in the morning. It sprays a fine film all over his mouth so that it's more likely to be absorbed in his mouth rather than to go down his throat.

Metagenics FolaPro® -- 60 Tablets is the l-5MTHF type of folate.

Neurobiologix Methyl Folate with Activating Co factors
I haven't tried this yet, but it sounds good. It has both
5-methyltetrahydrofolate and folinic acid as well as niacinamide which helps with the symptoms you may get from using a lot of 5-MTHF. I did get the adverse symptoms when I first took l-5-MTHF and this product would have been nice to have then.

Brain Takes Multiple Hits from Low B12 Levels

Low levels of vitamin B12 may contribute to cognitive problems for older adults in more than one way, according to a cross-sectional study…. 
...Note that previous studies have suggested that poor vitamin B12 status may be a risk factor for brain atrophy and possibly cognitive impairment.

...Although her group's observational study couldn't say whether boosting B12 would prevent or reverse cognitive effects, a prior randomized trial demonstrated that high-dose B complex supplements could slow down brain atrophy in older adults.
In that study, dubbed VITACOG, supplements did a better job of holding cognitive declines at bay than placebo among those with high homocysteine levels.
"So at least from this one clinical trial it appears that [supplementation] may have some benefit," Morris argued.
Her group dug deeper into their Chicago Health and Aging Project (CHAP), measuring vitamin B12-related markers in relation to brain MRI and neuropsychological test results 4.6 years later in 121 residents of Chicago's South Side, ages 65 and older.
After adjustment for age, sex, education, race, and serum creatinine levels to control for renal function problems that could have an impact on homocysteine, all of the B12-related markers affected global cognitive scores….

Study

Total blood mercury and serum measles antibodies in US children, NHANES
pubmed/21992842>
Gallagher CM, Smith DM, Meliker JR.
Sci Total Environ. 2011 Dec 1;410-411:65-71. Epub 2011 Oct 10.

Background: Environmental toxins, pathogens and host susceptibility cofactors may interact to contribute to disease. In vitro mercury exposure inhibited antiviral cytokines in human cells; however, little is known about the relationship between mercury and viruses in children. Children are susceptible to mercury toxicity; lower vitamin B-12 and folate levels and higher homocysteine levels may represent susceptibility cofactors.
This study aimed to evaluate associations between total blood mercury (Hg) and measles antibodies in children, and the influence of these susceptibility cofactors.

Design: Cross-sectional data on serum measles antibodies, Hg, homocysteine, methylmalonic acid (MMA, indicator of B-12 deficiency), and folate were obtained from the 2003--2004 NHANES for children aged 6--11 years with measles seropositivity (n=692). We used linear regression to evaluate relationships between measles antibodies and Hg, stratified by sex, MMA ?, folate b, and homocysteine?sample medians, adjusted for demographic, nutritional and environmental cofactors.

Results: Hg (range: 0.10--19.10 ?g/L) was inversely associated with measles antibodies (range: 1.00--28.24 units) in non-stratified analysis (n=692), yet positively associated among the subset of boys with higher MMA and lower folate (n=98). Among this subset with higher homocysteine levels (n=61), correlations were positive across all Hg quartiles relative to Q1 (Hg?0.20 ?g/L): Q2:?=6.60 (3.02, 10.19); Q3:?=8.49 (6.17, 10.81);
Q4 (HgN0.80 ?g/L):?=4.90 (2.12, 7.67) (ptrend=0.077).

Conclusion: Stratification by susceptibility cofactors revealed opposing directionality for correlations between Hg and measles antibodies, with positive effect estimates at lowest exposures only among boys with higher MMA, lower folate and higher homocysteine levels.

Good post, Andi!

One thing I am trying to figure out is that since the MTHFR mutation is hereditary and women AND men can have it, then it is likely that my son has it. So what if he can use the folinic acid efficiently enough?

I have read that Metafolin (L-methylfolate) and/or 5-MTHF might be better than folinic acid. What do you think?

The other important components to the SAME cycle are B6, B2, Betaine (aka trimethylglycine or TMG). I am considering adding all of these as well. Not sure on the doses yet though.

Kris said...

One other comment related to reflux - reflux medications significantly reduce the body's ability to absorb B12 - it has to be broken down by stomach acids in order to be used. If one is on reflux medication, ingesting B12 is not going to be very helpful.

The B12 that dissolves under the tongue and/or B12 shots are a much more effective way of getting the vitamin into your system.

Andi Durkin said...

Yes, I take Metafolin and folinic acid. Jett is able to take straight folinic because he only has one of the mutations. And yes, B6, B2, Betaine (TMG) are important as well. Jett and I both will be taking TMG. (I have the bottle) but haven't figured out how much yet. I've posted this info on the Tests and Treatment for Moms post.

Liora (Lourie Collins) Pearlman said...

hi, Andi is there any reason NOT to give our kids with DS the Metafolin? Why do you give Jett the folinic?

I have been using one product for Etel and myself, and it is time to reorder. But you got me second guessing myself about why I chose it in the first place for her! (Solgar 800 mcg a day from iherb.com here http://www.iherb.com/Solgar-Folate-Metafolin-Folic-Acid-800-mcg-100-Tablets/13961?at=0 it's a much better price than the FOlapro! They also have 400 mcg a day from Solgar- we use a wooden mortar and pestle to crush the tabs.) THANKS Liora

Liora (Lourie Collins) Pearlman said...

And p.s. we are both taking TMG. Etel at around 300 mg a day of powder, not carefully dosed- and me a different pill form at the dosage on the bottle at 500 mg/day.

Her naturopath had originally recommended 250 mg TMG a day, but Etel has grown in size since then.

Andi Durkin said...

Liora,
I give Jett both, just in case! So, no, I don't know of a reason NOT to give Metafolin.

I learned almost 2 years ago I have epilepsy. At the same time, I learned I had a severe B12 deficiency. I've been taking B12 shots, which have improved things a LOT, over 90% seizure reduction. (http://michellemasonrocks.blogspot.com/2015/12/how-i-manage-seizures-without-drugs.html) Which got me to thinking about the other 10%...if it was low B12 causing my seizures, why weren't they gone completely? And why did I have low B12 anyway? I'm not vegetarian, I eat meat daily. Then I learned if you are low in folate, it will cause low B12, and then I learned about the MTHFR mutation and folinic acid. Which brought me to your blog. Very well written, GREAT information, HUGE thank you! You've done amazing work and are helping people.
