Secreting Gland:
Thyroid Gland

Overview

Thyroxine (T4) is the principal hormone produced by the thyroid gland and serves as the body's primary circulating thyroid hormone. Although T4 has relatively low biological activity itself, it is converted within tissues into Triiodothyronine (T3), the active thyroid hormone responsible for regulating metabolism, energy production, growth, and cellular function throughout the body.

Within GUNA's Low Dose Medicine philosophy, Guna Thyroxine (T4) is traditionally used to support the physiological regulation of thyroid function and the body's natural endocrine balance. Rather than replacing endogenous thyroid hormone production, it is intended to support healthy thyroid regulation and normal metabolic activity.

Primary Physiological Actions

Thyroxine (T4) plays an important role in:

• Supporting healthy thyroid function.
• Regulating basal metabolic rate.
• Supporting cellular energy production.
• Promoting healthy oxygen utilisation by tissues.
• Supporting carbohydrate, protein, and fat metabolism.
• Maintaining normal body temperature.
• Supporting cardiovascular function.
• Promoting healthy neurological development and cognitive function.
• Supporting healthy skin, hair, and nail growth.
• Contributing to healthy musculoskeletal function.

Traditional Indications

Within biological and bioregulatory medicine, Guna Thyroxine (T4) is traditionally considered where support of thyroid regulation and metabolism is desired, including:

• Functional hypothyroid tendencies.
• Sluggish metabolism.
• Reduced vitality.
• Fatigue.
• Cold intolerance.
• Weight management programmes.
• Reduced physical performance.
• Reduced mental energy.
• Healthy ageing programmes.
• General endocrine regulation.

Commonly Used by Practitioners For

Common Complementary Remedies

Depending on the clinical presentation, Guna Thyroxine (T4) is commonly combined with:

• Guna Tri-Iodothyronine (T3) – complementary thyroid hormone regulation.
• Thyreoidea suis – comprehensive thyroid gland support.
• Hypophysis suis – pituitary regulation.
• Hypothalamus suis – neuroendocrine regulation.
• ACTH D6 – endocrine axis support.
• Coenzyme Compositum – cellular metabolism and energy production.
• Ubichinon Compositum – mitochondrial function and vitality.
• Guna Mela-tonin – circadian rhythm and neuroendocrine balance.
• Lymphomyosot – lymphatic and metabolic support.

Dosage

15–20 drops twice daily.
