I know I harp on about this…
But supplements I trusted for years actually caused severe Peripheral Neuropathy.
When I first looked at my symptoms, MS seemed like the only logical answer — nerve pain, numbness, tingling, dizziness, fatigue — it all fit. But after years of searching, the real cause was something I never expected… Vitamin B6 toxicity.
Excess B6 makes your nervous system extremely sensitive.
An inflamed nervous system can affect the tissues around it — muscles, tendons, joints — making everything more painful and reactive.
Since being diagnosed, I’ve been able to help others ask their GP the right questions and finally get answers to their unexplained pain.
👉 Around 50% of neuropathy cases are classed as “idiopathic” (no known cause).
But B6 isn’t tested in standard blood work — you have to specifically request a “plasma P5P test.”
When mine was finally tested, my B6 level was over 925 nmol/L — too high for the machine to read.
The normal reference range is 20–125 nmol/L.
⏱️ It’s important to test for it quickly — B6 levels can drop back to normal within days, but the nerve damage can take months or even years to recover from.
We only need 1.3–1.9 mg of B6 a day, yet in Australia some B-complex, magnesium blends and multivitamins contain up to 50 mg per tablet — more than 25 times the daily requirement.
⚠️ The TGA (Therapeutic Goods Administration) now requires warning labels on any product containing over 10 mg of B6 due to the risk of nerve damage.
And it’s not just supplements —
B6 is also added to some energy drinks, protein powders, protein bars, and even certain melatonin products.
If you’re experiencing unexplained tingling, burning, or numbness — especially if you take supplements or use fortified products — it’s worth checking your B6 levels.
