hi, thanks for the reply.
No he has not.
he also did a mineral testing, both blood and hair.
His Iodine is normal. No heavy metal poisoning.
strange thing - the hair test shows zinc, magnesium, calcium deficiency, while the blood test does not. Which one is correct - internet opinions split 50/50. Hubs tried zinc supplement for a month - zip. No change of symptoms, which shows that either he has no deficiency or zinc does not work.
