Hi.
Synthyroid alone is sufficient to treat
hypothyroidism because it is potent, better tolerated, dosed once daily, and the response can be easily monitored by
thyroid function tests. Actalin is a nutritional supplement which contains various vitamins, minerals and a good amount of
iodine. Taking excess iodine can result in overactive thyroid which can cause sudden
weight loss, a rapid or irregular heartbeat, sweating, and
nervousness or irritability. So, I advise you not take these supplements, continue taking Synthyroid as prescribed by your doctor, and monitor the response periodically by measuring thyroid hormones.
Hope I have answered your query. Let me know if I can assist you further.
