Multivitamin deficiencies in folate and vitamin C are also one of the hyperthyroidism complications. Individually or combined Folic acid and vitamin C were introduced to hyperthyroid induced rats. A relative enhancement in the thyroid hormones with a normal lipid profile was noticed. Previous researches confirmed that the depletion on the lipid in hyperthyroidism will be gained after treatment.
