What is Synthroid?

Synthroid is a synthetic thyroid hormone replacement medication used to treat hypothyroidism — a condition where the thyroid gland doesn't produce enough T4 hormone on its own. T4 is the hormone that regulates how your body uses energy, and when levels are low, virtually every system slows down: metabolism, heart rate, digestion, temperature regulation, and cognitive function. Synthroid restores T4 to normal levels, allowing those systems to function properly. It's taken once daily on an empty stomach and requires periodic blood tests to dial in the right dose.

T4 hormone replacement

Synthroid replaces the thyroxine your thyroid isn't producing, giving your body the hormonal signal it needs to regulate metabolism and energy at a cellular level.

Symptom reversal

With consistent use, symptoms like fatigue, weight gain, brain fog, cold sensitivity, constipation, and dry skin typically improve as hormone levels normalize.

Dose precision

Because thyroid function is highly individual, your clinician will use TSH blood tests to find and maintain your optimal dose — small adjustments can make a significant difference in how you feel.
