T3 UNI-PHARMA 25 mcg
This page identifies the listed UNI-PHARMA liothyronine presentation and explains its relationship to T3, thyroid physiology, strength, pack, monitoring context, safety and UK-facing product information.
What is liothyronine?
Liothyronine is a synthetic form of triiodothyronine, commonly called T3. T3 is the more biologically active thyroid hormone and acts more quickly than T4/levothyroxine. Its effects extend across metabolism, cardiovascular function, temperature regulation and other systems.
T3 is an active thyroid hormone
Unlike T4, which acts partly as a circulating precursor, T3 directly engages thyroid-hormone receptors in tissues.
Different from “Cytomel” as a brand
“Cytomel” is a brand name often used generically in online searches. UNI-PHARMA is a separate manufacturer presentation containing liothyronine sodium.
Different from T4
Liothyronine and levothyroxine are related thyroid medicines but have different pharmacokinetic profiles and should not be treated as interchangeable based only on microgram strength.
Why T3 requires careful interpretation
Thyroid-hormone effects are not judged only by body weight or subjective energy. Symptoms, thyroid blood tests, other medicines, cardiovascular history and the reason for treatment all matter in clinical decision-making.
Monitoring
TSH, free T4 and sometimes T3 measurements can provide context depending on the clinical question, but interpretation depends on timing and individual circumstances.
Cardiovascular effects
Excess thyroid-hormone effect can increase heart rate and contribute to palpitations, tremor, sweating, anxiety and other symptoms.
Individualisation
Age, heart disease, endocrine conditions, pregnancy status, concurrent medicines and other factors can materially change risk.
Important safety context for liothyronine
Liothyronine can produce clinically significant effects if thyroid-hormone exposure is excessive or poorly matched to the individual situation.
- Palpitations, increased heart rate, tremor, sweating, anxiety, sleep disturbance and heat intolerance can occur with excessive thyroid-hormone effect.
- Stimulants and other agents that increase cardiovascular demand can compound symptoms and risk.
- Combining T3 with T4 changes total thyroid-hormone exposure and can make self-directed adjustment difficult to interpret.
- Body weight, temperature or perceived energy are not reliable substitutes for appropriate thyroid assessment.
- Severe chest pain, fainting, marked shortness of breath or rapidly worsening symptoms require urgent medical assessment.
Checking the UNI-PHARMA presentation
Use manufacturer name, active ingredient, strength, pack quantity, batch/lot information, expiry, leaflet and packaging condition together when assessing a product presentation.
Manufacturer
UNI-PHARMA is the manufacturer stated for this listed T3/liothyronine presentation.
25 mcg strength
The listed product contains 25 micrograms of liothyronine sodium per tablet. Similar products can use different strengths, so the label should be checked carefully.

The listed presentation contains 30 tablets. Pack design or market presentation can change and appearance alone cannot prove authenticity.
Product identity is not the same as UK regulatory status
UK liothyronine medicines and products from other markets can have different authorisations, presentations and supply requirements. The exact legal classification and lawful supply conditions should be checked against current official information for the specific product and jurisdiction rather than inferred from the active ingredient or brand-style name alone.
Common questions about T3 UNI-PHARMA
What is the active ingredient?
The listed UNI-PHARMA product contains liothyronine sodium, the pharmaceutical form of T3.
What strength is each tablet?
The listed strength is 25 micrograms of liothyronine sodium per tablet.
How many tablets are in the pack?
The listed presentation contains 30 tablets.
Is T3 the same as T4?
No. T3/liothyronine is the active thyroid hormone, while T4/levothyroxine has a longer time course and is converted to T3 in tissues.
Is UNI-PHARMA T3 the same thing as Cytomel?
They share liothyronine as the active substance, but Cytomel is a specific brand name and UNI-PHARMA is a separate manufacturer presentation. Product-specific regulatory status should be checked separately.
