    Is there any reason why  Niagen should not be used if Levothyroxine is being taken for hypothyroidism?

    • James Berry James Berry United States says:

      I too am on Levothyroxine 112mg/day and started taking Basis a compound similar to Niagen and within two weeks came down with Peripheral Neuropathy and joint and muscle pain.  Did you ever get an answer to your question about Lovothroxine and Niagen use? Any input would be greatly appreciated.  James Berry

        If you have a methylation defect, NAD can precipitate neuropathy, pain, fatigue. I'm guessing if you took methylated B vitamins with the NAD it might prevent those side effects, but everybody's different.

          I experienced major lower back and neck pain while taking NIAGEN (nicotinamide riboside) -- shouldn't this be listed as a side effect. It also, made my hurting joints extremely noisy. I relate my symptoms similar to eosinophilia-myalgia syndrome (EMS).

          Doses more than 250 mg of nicotinamide (B3) now cause the same pain too.

          I have taken for years MSM, TMG and methylated B vitamins.

          I have not experienced the same when taking NADH or coenzymated B3 (nicotinamide adenine dinucleotide).

          Seems to me the pain can not be from the NAD.
