Understanding Free T3 (FT3)
Free T3 (FT3) is a key biomarker in blood tests that free t3 is an active thyroid hormone that regulates metabolism.
What is Free T3?
Free T3 is an active thyroid hormone that regulates metabolism.
Normal Range
The normal Free T3 range is between 2.3 and 4.2 pg/mL.
High Free T3 Levels (Above 4.2 pg/mL)
Causes of High Free T3
High Free T3 is often seen in hyperthyroidism and Graves’ disease. Managing thyroid hormone balance through medical intervention is required.
Health Effects of High Free T3
Excess Free T3 accelerates metabolism, causing rapid heartbeat, excessive sweating, nervousness, muscle breakdown, and weight loss.
Low Free T3 Levels (Below 2.3 pg/mL)
Causes of Low Free T3
Low Free T3 can result from hypothyroidism, chronic stress, or nutrient deficiencies. Optimizing iodine and selenium intake can help improve thyroid function.
Health Effects of Low Free T3
Low Free T3 leads to sluggish metabolism, weight gain, fatigue, and impaired cognitive function.
