Thyroid stimulating hormone (TSH)Updated 3 months ago

What is thyroid stimulating hormone (TSH)?
TSH is produced by the pituitary gland and stimulates the thyroid to release hormones T4 (inactive) and T3 (active). T3 regulates metabolism and provides negative feedback to control TSH levels. Abnormal TSH levels can signal thyroid issues.

Why is TSH important?
TSH helps assess thyroid health, which influences metabolism, growth, development, temperature, and energy.

TSH levels:

• Very low: 0–0.5 uIU/mL
• Low: 0.5–1 uIU/mL
• Optimal: 1–2 uIU/mL
• High: 2–5 uIU/mL
• Very high: >5 uIU/mL

Specific ranges for cardiometabolic programs:

• Optimal: 0.45–5.33 uIU/mL
• Pay attention: >5.33 uIU/mL
• Alert: >10 uIU/mL

Maintaining optimal TSH levels:

• Diet: Reduce iodine, and follow Mediterranean or vegetarian diets.
• Lifestyle: Quit smoking, exercise, and improve sleep.
• Supplements: Selenium, zinc, vitamin D, and others may help balance TSH.

DISCLAIMER:

If you are concerned about your TSH levels always consult your physician.
