Life Extension Triple Action Thyroid is a vegetarian capsule supplement bringing together a carefully selected blend of nutrients and botanical extracts to support healthy thyroid function. Each two-capsule serving delivers iodine (350 µg, sourced from kelp and potassium iodide), vitamin B12 as methylcobalamin (200 µg), vitamin A as palmitate (300 µg), magnesium as magnesium carbonate (20 mg), and the amino acid L-Tyrosine (200 mg). Botanical ingredients include 500 mg of Sensoril Ashwagandha extract — standardised to 32% oligosaccharides and 10% withanolide glycoside conjugates — alongside 200 mg of GS15-4 fermented Korean ginseng root extract and 100 mg of guggul gum resin standardised to 10% guggulsterones.
Life Extension is a well-regarded US supplement brand with a long-standing reputation for research-led formulations, and Triple Action Thyroid reflects that approach with its multi-ingredient profile targeting thyroid gland support from several angles simultaneously. The product is suited to adults looking for a comprehensive thyroid-focused supplement as part of a varied and balanced diet.
Each bottle contains 60 vegetarian capsules, with a recommended daily dose of 2 capsules.
