Most people with hypothyroidism produce enough T4 but their bodies do not convert it efficiently into T3.
Thyroxine (T4) is made from iodine and tyrosine. Deiodinase, the enzyme that converts T4 into T3 is made from selenium and cysteine. The other nutrients in TSF contribute to the manufacture and utilization of thyroid hormones.
Suggested Use: 4 tablets daily – in divided amounts with meals that are high in protein (e.g., 2 with breakfast, 2 with lunch). If not possible to take with high protein meals, then take between meals on and empty stomach (e.g., 2 tablets upon arising in AM, 2 in mid-afternoon).
