INFO - Risks of too much B6

[Guest guest]

What is the health risk of too much vitamin B6?

Too much vitamin B6 can result in nerve damage to the arms and legs.

This neuropathy is usually related to high intake of vitamin B6 from

supplements, [28] and is reversible when supplementation is stopped.

According to the Institute of Medicine, " Several reports show sensory

neuropathy at doses lower than 500 mg per day " [12]. As previously

mentioned, the Food and Nutrition Board of the Institute of Medicine

has established an upper tolerable intake level (UL) for vitamin B6 of

100 mg per day for all adults [12]. " As intake increases above the UL,

the risk of adverse effects increases [12]. "

************************************

Infrequent adverse events include headache, nausea, sedation, and mild

paresthesias (3). Chronic consumption of large doses may cause severe

neuropathies, ataxia, respiratory difficulties, and profound sedation,

although reversal usually occurs following discontinuation (4).

When my numbness showed up, I was only taking 50 mg of B6 a day and not every

day - though most. However, I had taken it for many years. My doctor is still

wondering why my level is so high with such a low dose though I did read that

duration of time taken does make a difference. It takes 6 months or more, from

my reading, for the symptoms to go away.
