What is Herbs of Gold Selenium 150 Max?

Herbs of Gold Selenium 150 Max provides selenium in the well-absorbed selenomethionine form. Each capsule delivers 150mcg of selenium to support thyroid function, immune health, and antioxidant protection.

Selenium is an essential trace mineral that acts as a cofactor for important antioxidant enzymes including glutathione peroxidase. It helps protect cells from oxidative damage caused by free radicals.

The mineral plays a crucial role in thyroid hormone metabolism, supporting the conversion of inactive T4 to active T3 thyroid hormone. Selenium also supports healthy immune system function.

Selenomethionine is a naturally occurring form of selenium found in foods, offering superior absorption compared to inorganic selenium forms.

Each capsule contains:

Selenomethionine - Selenium in the organic form naturally found in foods. This form is better absorbed and retained by the body compared to inorganic selenium.

Selenium acts as a cofactor for glutathione peroxidase, a key antioxidant enzyme. Essential for thyroid hormone metabolism, supporting T4 to T3 conversion. Supports healthy immune system function. During periods of stress our bodies uses up more selenium.

Does not contain egg, milk, peanut, soy, tree nuts, animal products, gluten, lactose or artificial colours, flavours or preservatives.

Adults - Take 1 capsule daily, with food, or as directed by your health professional. Not recommended for children under 15 years.

Always read the label and follow the directions for use.

Selenium is toxic in high doses. A daily dose of 150 micrograms for adults of selenium from dietary supplements should not be exceeded.

Vitamin and mineral supplements should not replace a balanced diet.

"Selenium is a trace mineral that quietly does a lot of heavy lifting in the body — from supporting thyroid function and immune health to protecting cells from everyday oxidative damage. One of its most important roles is activating glutathione peroxidase, an enzyme the body relies on to neutralise free radicals and manage oxidative stress. Selenium 150 MAX delivers 150mcg of selenomethionine, the organic form best recognised and utilised by the body, in a single daily capsule."

Frequently asked question

Selenium is essential for the production and regulation of thyroid hormones. The body produces thyroid hormone in an inactive form (T4), which must be converted into its active form (T3) before it can be used. This conversion relies on selenium-dependent enzymes. Without adequate selenium, this activation process is impaired, which can affect metabolism, energy production, body temperature, and cognitive function — even when the thyroid gland itself is working normally.

Selenium is an essential trace mineral the body cannot produce on its own. Because Australian soils are generally low in selenium, adequate daily intake through diet alone can be difficult to achieve consistently. You may benefit from supplementation if you experience fatigue, poor immune function, or thyroid-related symptoms such as sluggish metabolism. A blood test ordered by your health professional is the most reliable way to confirm your selenium status.

Yes, selenium toxicity can occur at high doses. The upper limit is 400mcg daily from all sources. Don't exceed the stated dose without guidance.

Brazil nuts are the richest dietary source — just 1-2 nuts sourced from South America can provide close to the daily requirement. Other sources include seafood, organ meats, poultry, eggs, and dairy. Plant foods like grains and legumes contain selenium, but levels vary with soil content. As Australian soils are generally selenium deficient, diet alone may not consistently meet daily needs.
