iHerb Customer Reviews

Great for chronic fatigue syndrome.

Posted by iHerb Customer on January 22 2018 | Verified Purchase

This has a very impressive and very strong positive effect against my chronic fatigue syndrome that has lasted 25 years. Very effective, and am highly impressed. Am taking it with strong Lugol's iodine. I felt that potassium iodide 130mg + very high Lugol's (lugol's has iodine + potassium iodide) is amazing. Curing MTHFRC677T with L-methylfolate + folinic acid while saturation the bodie's iodine and iodide levels is the cure in my case.

Thanks for your feedback!

Hopefully won't ever need these.

Hopefully won't ever need these. FDA says they don't really expire, even though the expiry date says 2018...

Thanks for your feedback!

Peace of mind

I bought this product as the war of words may turn into the real thing between USA and N Korea. I am in the UK but felt that prevention would be better than cure! If I have no need to take them for radiation I will take them for thiroid problems that also run in our family. Reading the reviews they may well help with tiredness especially.

Thanks for your feedback!

KI supply for emergency times

Korea hasn't been nuked by the little fat boy yet (DPRK), but it's a good idea to have a supply - I read that prices went up to US$200 in California, but iHerb's prices are always excellent. My favourite is Vitamin D3, Healthy Origins, but you have an amazing selection. Time to reorder ;)))
