Did you know that your genes are affecting your thyroid?

Whether you like it or not, genetic defects are at work in your body, directly or indirectly interfering with thyroid production.  In this enlightening and informative presentation, Dr Lynch and Dr Christianson delve into an area of medicine called ‘methylation’ and ‘nutrigenomics.’

Be sure to inform your healthcare professional about this recording as they will not want to miss out on cutting edge thyroid research.

Nutritional Support:
Consider HomocysteX Plus for supporting riboflavin requirements and the MTHFR defect. Be sure to discuss appropriate dose with your physician.

I watched your thyroid presentation and the slide that contained the detail information about how MTHFR impacts thyroid was not displayable and you did not go into detail in explanation on this. Could you please create a follow-up post to this one that provides the diagram and describes in detail the impact of MTHFR on thyroid? Thank you!

I recently learned I am hyperthyroid based on bloodwork when I went to the ER due to a rapid heart beat. We did all the thyroid workup and found nothing. In fact my uptake scan says I hypothyroid even though my labs are showing hyper. TSH 0.01. I had no thyroid antibodies present. We did find that I am compound hetero C677T and A1298C. I also carry a HLA DQ2 A0505 rare celiac gene. Any idea what is going on with the thyroid here? My Dr’s are once again giving me the “there are some things we know and some things we don’t know and you are what we don’t know”. My last homocysteine level was 10.3 a year ago and my thyroid was completely normal then. We will be drawing a homocysteine in the next few weeks.

Angela, I’m only jumping in because I see there was no answer for your question.

When they told you that you had hyperthyroid, did they base it on that TSH number or did they test your Free T4 and Free T3? You can’t know you are hyperthyroid without those. I am hypothyroid/Hashimoto’s, but had a lot of rapid and irregular heartbeat, and a lot of anxiety/panic before I was diagnosed. Those symptoms can go with either extreme of thyroid dysfunction.

Hope you have got things settled.

Dr. Ben,

I am homozygous C677T and hypothyroid. Ive been taking Metanx, Armour, Levothyroxine, iodine, adrenal supplements, etc. for a couple of years. I’ve eaten a whole foods organic diet for 8+ years. Completely gluten free for 6 mo. grain free now for a month. I started taking homosystex plus a few weeks ago. I eat greens, nothing processed, avoid many foods due to intolerance, drink RO water, no soda, etc etc. and I have had very little to no improvement. In fact, the past 6 months or so, I have been even more depressed, anxious, and have put on lots of weight despite eating healthy. I also have developed alcohol cravings during the past year or so. My dr. is kind of at a loss. I’m at a loss and I’m so sick of being sick and tired and depressed. Any suggestions? I listened to you on the thyroid summit and it was very overwhelming to me. Please help me if you can!!!

I can’t get the video to play. The podcast will run but I’m a better visual learner. Any suggestions?

Julie, Did they test you for Hashimotos? Hashi people don’t tolerate iodine well. That may be the rub. And have you started any methylation protocols?

“ACMG Practice Guideline: lack of evidence for MTHFR
polymorphism testing”

Seems to be conflicting opinions about the value of treatment for MTHFR. Who is right?

I am homozygous for A1298c. I thought I finally had an answer for many of the listed illnesses I have. If this testing is irrelevant then what am I to do?

I recently saw a video that a specialist who was talking about Hillary Clinton taking thyroid medicine said that armour thyroid causes blood thickening. If this is true then wouldn’t one that is hypothyroid and takes armour, compounded or otherwise, want something different??and if so, then what?? Naturethroid????
