Dangerous for me

Posted by beafawcett on Feb 11, 2016

i found that this product contains over 7000% of the RDA of thiamine. I also found it is possible get thiamine toxicity, which I did. i have used other Thoren products with lower amounts of these Vitamins. It seems absurd to have such huge doses in a single capsule, which made me VERY SICK. I really think this product has significant dangers and would suggest people be very careful about using it. It seesm to have been produced with the nonsensical idea that more is always better. seriously not happy.

I take this as it has folate instead of folic acid due to MTHFR gene.

Very strong supplement, so use with caution.

I was only taking one capsule a day for a year, but developed vitamin B toxicity. The skin on my knuckles became hard and dry. At first I thought it was caused by my dish washing soap but then I noticed my face was breaking out. I did some research online about skin problems and found out that high doses of vitamins cause liver damage. I immediately stopped taking supplements. After only a couple of days, I noticed an improvement in my skin. The dryness is almost completely gone and face is clearer. From now on, I'm only going to take the rda.

Capsules are on the larger side

Posted by 4828874234867250422 on Nov 16, 2015

I love Thorne products and will continue to buy all my supplements from Thorne. However due to having a Lapband these specific tablets are too big for me to take. Other than that, no obvious side effects but did feel a lot better after taking them (when able).

I had jittery effect from these vitamins and hot flashes. Gave them to my aunt who didn't have any beneficial results. she caught a flue while taking them and they are supposed to rise your immune system.

I love this B Complex, really helped with my pyrroles and MTHFR management

Posted by grainfreeliving on Jul 22, 2015

Although Thorne does other B's specifically aimed at MTHFR, I have found that I am doing better when I switched to this one. I have the a1298C defective gene and this B really helps. It does not make me feel sick and I can even take it close to bedtime and it does not keep me awake. I range from 1 to 3 a day, depending on my stress levels and I love how I can be in control of my dose according to my needs.
