This question is for my son of 20. He suffers from Hashimoto (thyroid autoimmune disease) and chronic fatigue. We had his blood tested in every little detail and it's obvious his energy system is out of whack. His adrenals are semi-exhausted, Q10 is too low, B12 is limit, copper very low, ... Very slow heartbeat too since he is a baby. We had him checked for Pfeiffer, CMV, Lyme... nothing active. A doctor gave him way too much B6 and some B12 which made things temporarily worse. He feels fine with multvitamins and lots of Q10. His diet is fine, mostly organic, no gluten, lots of fruits, vegetables, nuts, good fats, proteins, ... It costs me a fortune LOL His body type is very athletic and he still gets a boost of running or swimming, something he tries to practise every day. But it is a daily struggle to get up, stay awake, be able to study (engineering), have no brainfog, ... He feels sick in cycles. It breaks my heart. I convinced him to reconsider vit B12 (hydroxy) this summer. He got an injection and everything went fine. Last week he had one again and he felt really sick for three days. He is a little bit desperate for the coming six weeks. Exams will be tough ... What would you advise?
