I found out about
2 years ago that I have homozygous C677T. My OBGYN and my LLMD worked together to figure out my diagnosis/ dosage. They had me slowly build up to taking what is now my current dosage. I almost immediately noticed an energy boost and felt great for about
3 weeks while my body adjusted to actually having what it needed, and then it hit a wall while it briefly freaked out about
actually having what it needed--so I just took a short break and started over building up to my dosage. Since then it has been smooth sailing.
There are several good websites that explain MTHFR (mthfrgenehealth.com and dietvsdisease.org both explain it in simple terms). Basically MTHFR is broken into 2 main categories: C677T and A1298C. From the research I have done over the last two years it appears that some people with A1298C can live ordinary lives without ever realizing they have it, and those like you, with homozygous A1298C only have around 40% function loss (ability to process folic acid into folate) so they seem to have an easier time managing it. Like lyme, everyone deals with MTHFR differently so just because something works for me doesn't mean it will for you and vice versa. With my double hit of C677T my function loss is around 70% so I have to take higher doses of l-mythlfolate than someone who was heterozygous or had the A1298C version. I had blamed my poor vitamin levels on lyme but it turns out to be mostly from MTHFR. Good news I found a gummy multi-vitamin (because you are never too old for gummies) that tastes pretty good (Smarty Pants brand) that is actually made for us. This is the first multivitamin I have been able to take so I was pretty excited to stop taking so many different pills. We tend to have a hard time processing B-vitamins so methylated b-vitamins are what you want to look for--this just means that it is already activated/broken down so our bodies can use it. Reading up on the two main types of MTHFR it seems that C677T has a harder time with elevated homocystine levels which can cause heart issues such as strokes, and the A1298C seems to have a harder time producing serotonin which can lead to more mental health issues such as depression and anxiety.
In short you want to (1) stay away from folic acid and instead take l-methylfolate--just talk to your doctor about
how much you need. I personally alternate between l-methylfolate pill and my multi-vitamin gummies every other day, but you should not need as high a dose as me and the gummies alone may be enough; (2) Use methylated B vitamins; and (3) discuss it with your LLMD.
The good news is that many things you are (probably) already doing to fight lyme are also very helpful dealing with MTHFR :e.g. staying away from processed food and refined sugar, detoxing, using filtered water. So it should not be a big change for you once its all said and done. I wish you all the best and please let me know how things are going
