Support your energy, metabolism, and hormonal balance with our At-Home Thyroid Health Blood Test. This profile measures TSH, Free T4 (FT4) and Vitamin D (25-OH) to assess thyroid function, metabolic control, and the wider impact on immunity, mood, and bone health. Ideal for those experiencing fatigue, weight changes, low mood, brain fog, temperature sensitivity, or with known or suspected thyroid conditions such as hypothyroidism, hyperthyroidism, Hashimoto’s, or autoimmune thyroid imbalance.
Your thyroid plays a crucial role in maintaining metabolism, energy levels, body temperature, mood, and overall hormonal balance. When the thyroid becomes underactive (hypothyroidism) or overactive (hyperthyroidism), it can lead to symptoms such as tiredness, weight changes, low mood or anxiety, brain fog, skin or hair concerns, and reduced quality of life.
The Thyroid Profile from Vitalync Diagnosis measures key thyroid hormones and includes Vitamin D (25-OH) for added insight into immune function, bone health, and endocrine balance — offering a more complete picture of your wellbeing.
The pituitary “messenger” that signals how much thyroid hormone to produce. High or low levels may indicate hypo- or hyperthyroidism.
The main active thyroid hormone. When analysed alongside TSH, it helps determine thyroid function and the severity or stage of imbalance.
Supports immune health, bone strength, mood, and hormonal balance. Deficiency is common in the UK and can worsen fatigue, low mood, or thyroid-related symptoms.
This at-home thyroid blood test is suitable for:
People with persistent fatigue, weight gain or weight loss, or temperature sensitivity
Anyone with low mood, anxiety, brain fog, or low energy
Those with a diagnosed thyroid condition who need regular monitoring
Individuals with a family history of thyroid or autoimmune disorders
Anyone wanting to check Vitamin D status alongside thyroid hormones
