Still fine for you. However, when taking HD B1, there is a protocol to follow. In short, there is interaction between several vitamins and trace elements.
I then asked AI to help clarify the why and the how for other readers.
AI says, as if LucH were speaking to JD:
Glad it has lasted for you, JD! That is fantastic personal success, and it actually makes perfect sense given the specific combination you used.
When you take thyroid hormone alongside thiamine, you are directly addressing the systemic metabolic bottleneck. In the bioenergetic framework Dr. Ray Peat talked about, low thyroid impairs the liver's ability to clear excess estrogen. High estrogen triggers nitric oxide, which over-relaxes (smoothes out) the blood vessels in the lower extremities, causing blood to pool and forcing the heart to beat faster to compensate (POTS). By taking thyroid and thiamine together, you restored cellular energy and vascular tone simultaneously, which is why your results have been so stable.
However, for other readers looking to replicate this, it is crucial to understand why standalone High-Dose Thiamine (HD B1) protocols usually require cofactors. Skipping them can cause issues for the average person due to several factors:
Magnesium is Mandatory: Thiamine cannot be converted into its active, usable form (thiamine pyrophosphate) without magnesium. Mega-dosing B1 alone rapidly depletes magnesium stores. This frequently triggers severe muscle cramps, anxiety, and heart palpitations, which people often mistake for a worsening of their POTS.
The "Paradoxical Reaction": High doses of B1 can kickstart dormant mitochondrial pathways so suddenly that it causes a temporary, severe flare-up of autonomic symptoms. Adequate magnesium, potassium, and baseline nutrition help buffer this transition and prevent a metabolic shock.
B-Complex Imbalance: Flooding the system with massive doses of a single B vitamin can eventually create a functional deficiency in other B vitamins (like B2 and B3) that share the same cellular energy pathways.
In short, JD's success is a great example of the bioenergetic approach working perfectly because the underlying thyroid and estrogen pieces were addressed. But for most people starting a high-dose thiamine protocol on its own, skipping cofactors like magnesium is a frequent cause of metabolic stalls or severe symptom regressions. Keep it simple, but keep the underlying biochemistry in mind!
