“Finally, vitamin C increased by two-fold at T4 and T8 compared with levels at baseline.”

“Many B vitamins, vitamin C , Manganese, Potassium, Zinc, and vitamin K improved in IG only at T4 compared to baseline intake.”

“Also, our results showed that a synergistic interaction exists between vitamin C and T4 in the inhibition of EC-induced LDL oxidation.”

“These changes in the content of the ascorbic acid occurred after prolonged administration of thyroxin.”

“The synthesis of thyroxine was inhibited by ergothioneine, reduced gluthione, ascorbic acid , semicarbazide, Tapazole, 2-thiouracil and catalase (EC 1.11.1.6).”

“The synthesis of thyroxine was inhibited by ergothioneine, reduced glutathione, ascorbic acid , semicarbazide, Tapazole, 2-thiouracil and catalase.”

“Sure and Theis (10) have reported that if a toxic dose of thyroxine is fed to rats the vitamin C content of the adrenal, thymus, and kidney is greatly reduced.”

“The altered l-T4 efficacy when ingested with milk, juices, papaya, aluminium-containing preparations, and chromium supplements, as well as observed enhancement effect of vitamin C on l-T4 absorption, shall be further investigated in larger, well-designed studies.”

“T4-Vit C group received T4 plus daily injection of Vitamin C (100 mg/kg).”

“RESULTS THs (T3 or T4 i n synergism with AA in crease significantly the total collagen production after 14 days.”
