Hi,
Actalin contains various minerals and vitamins like iodine,
ashwagandha root extract,
magnesium, vitamin D, vitamin A, niacin,
riboflavin, zinc and many more that is used to support the optimal thyroid function. On the other hand,
Synthroid is used in the treatment of underactive thyroid or
hypothyroidism. Taking any other supplement or multivitamins and multi minerals like Actalin with Synthroid may cause someone to require a higher and lower dose of Synthroid. Many medications like multivitamins and multi minerals or supplements can change the absorption, breakdown or response to Synthroid when they are taken with Synthroid. Ashwagandha is one of the active ingredients of Actalin that may increase thyroid hormone levels. So before using Actalin or any medication along with Synthroid, you should consult your doctor first and without your doctor's permission, you should not start taking any medication or supplements.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Zubayer Alam, General And Family Physician,
