Key takeaways
- Selenium is a trace mineral the body needs only in small amounts. It works through selenoproteins involved in thyroid hormones, DNA and cell protection.
- Hoola provides 15 mcg of selenomethionine per gram, which is 150 mcg in the 10 g daily serve.
- We chose selenomethionine because it is a highly bioavailable form, more readily absorbed than some other forms of selenium.
- Selenium in food varies with the geographic source of that food. Around one in 10 people in Australia over 71 years do not get the estimated requirements of selenium from their diets.
- One 10 g scoop in cold water each morning. No half serve, no double serve, and the benefits build with consistency.
What is selenium, and what does it do in your body?
Selenium is a mineral found in the soil, and a nutrient the body needs to stay healthy. In Hoola, it supports thyroid hormone metabolism and antioxidant defences.
Think of it as a tiny nutrient doing big things. You only need a very small amount, and it still plays a key role in your metabolism. Selenium functions as an antioxidant, in redox reactions and in thyroid metabolism.
It does that work as a component of selenoproteins and enzymes. Those proteins help make DNA and protect against cell damage and infections, and they are involved in reproduction and the metabolism of thyroid hormones. Selenium is also needed for reproduction, to make DNA, to help protect cells, and to resist infection.
Your thyroid gland needs selenium to produce hormones and function properly. Most selenium in the body is stored in muscle tissue, though the thyroid gland holds the highest concentration because of the various selenoproteins that assist with thyroid function. Small but mighty, and mostly working out of sight.
Where does selenium fit into a day that already feels loud?
It sits in the background, protecting cells while everything else in your day competes for your attention. Energy should feel bright, not frantic.
Wired but tired is a familiar setting. Selenium does not switch that off on its own, and it is not a stimulant. It has attracted attention because of its antioxidant properties. Antioxidants protect cells from damage caused by things such as ageing, lifestyle choices, and environmental conditions such as pollution. Selenium is an antioxidant which reduces free radicals formed in the body.
There is an immune side to it too. Studies show that selenium helps control inflammation and supports a healthy immune system. It plays a role in how immune cells send signals, handle stress and fight infections.
In Hoola, selenium contributes to maintaining and supporting healthy immune system function, and to maintaining and supporting healthy thyroid gland function and metabolism. That is steady, structural work, the kind you feel as consistency rather than a hit.
Which form of selenium is in Hoola, and how much is in a serve?
Selenomethionine, at 15 mcg per gram, which is 150 mcg in the 10 g daily serve. That is 0.15 mg.
Every per-serve figure is the per-gram figure times ten, and both are published. No proprietary blends, no hidden doses. The ARTG certificate lists all 27 active ingredients with exact quantities per gram, so anyone can look up AUST L 508472 on the public register and check every number. Dietary supplements carry a label that tells you how much selenium is in the product.
Microgram amounts read small on paper. In milligrams: biotin 3,000 mcg = 3 mg, folate 890 mcg = 0.89 mg, chromium 400 mcg = 0.4 mg, potassium iodide 200 mcg = 0.2 mg, selenomethionine 150 mcg = 0.15 mg, molybdenum 80 mcg = 0.08 mg, vitamin B12 50 mcg = 0.05 mg, vitamin K2 50 mcg = 0.05 mg, vitamin K1 90 mcg = 0.09 mg, and vitamin D3 25 mcg = 0.025 mg, which is 1,000 IU.
No mega doses. Just smart daily support, with every ingredient at meaningful, purposeful dose and every quantity published. We provide full formula transparency, including the dosages of all functional ingredients, because there is nothing to hide.
Why did Hoola choose selenomethionine?
Because it is a highly bioavailable form of selenium, more readily absorbed than some other forms. We use active and bioavailable forms wherever possible, in line with Australian quality manufacturing standards.
It is also the form your body already meets at the dinner table. In foods, selenium is present primarily as selenomethionine along with selenocysteine. Soil and ground water contain inorganic forms of selenium, such as selenites and selenates, which plants take up and convert into organic forms, mostly selenomethionine and selenocysteine and their methylated derivatives. Dietary selenium is readily absorbed by the body, and absorption is largely unaffected by selenium status.
Hoola includes a curated set of essential trace minerals that quietly do the heavy work behind the scenes. Choosing the form is part of the formulation, not a footnote to it. Minerals should work with you, not simply pass through you. Tiny team, major impact.
How does selenium work with the rest of the formula?
It pairs with the other thyroid and antioxidant actives in the same scoop, which is the point of a single balanced daily dose rather than a shelf of separate supplements. The value sits in how the ingredients work together.
Selenium exerts its effects as a constituent of several selenoproteins, of which there are at least 30 in mammalian systems. It aids in thyroid hormone production, supports healthy immune system function and helps maintain cardiovascular system health. The iodothyronine 5'-deiodinases catalyse the conversion of thyroxine (T4) to its active metabolite, triiodothyronine (T3).
That is where the pairings matter. Potassium iodide at 200 mcg per serve supports thyroid hormone production, while selenomethionine supports the metabolism of those hormones. Magnesium ascorbate brings vitamin C and magnesium, supporting normal immune function, contributing to collagen formation, acting as an antioxidant, and supporting muscle function and the nervous system. Selenium's antioxidant role sits alongside it.
The ARTG Public Summary lists nine support areas: energy, stress response, cognition and memory, sleep, emotional wellness, immune, muscle performance, digestive and cardiovascular. Hoola is a daily wellness drink with nootropics, adaptogens, vitamins and minerals to support energy, focus and mental clarity. Calm clarity. Energised performance. A brighter way to live, every day.
Who tends to look for a selenium supplement?
People who suspect their diet is not covering the gaps, and people who want a broader base of daily support rather than one isolated mineral.
Most people get enough selenium from the foods they eat. Food is not uniform, though. Selenium is found in a range of foods, and the content varies with the geographic source of that food, because the amount of selenium in soil affects the selenium content of foods. Around one in 10 people in Australia over 71 years do not obtain the estimated requirements of selenium from their diets.
Hoola is listed on the ARTG to help prevent dietary vitamin and mineral deficiency, and selenium is part of that. We built it for modern lives, busy schedules and high ambition, for people who want more out of life, more balance, more adventure and more support. Real performance starts from the inside, from clarity, calmness, steadiness and emotional confidence. It helps you stay steady when life is a little heavy.
How should you take selenium day to day?
One 10 g scoop mixed into 300 to 400 ml of cold water, each morning. There is no half serve, no double serve and no weekly total.
Take it in the morning or early afternoon, and avoid taking it close to bedtime because of the caffeine. A 10 g daily dose of actives does not fit a practical capsule count, so Hoola is a powder.
Consistency beats intensity. Most of our customers feel the biggest benefits with consistency, and adaptogens may take four to six weeks for their full benefits. The 150 g pouch is two weeks, which is enough to see how you feel. One scoop. Steady energy. All day.
Frequently asked questions
What are the benefits of taking a selenium supplement?
Selenium supports thyroid hormone metabolism and antioxidant defences. It works through selenoproteins, which play critical roles in thyroid hormone metabolism, DNA synthesis, reproduction, and protection from oxidative damage and infection. Selenium is required for healthy thyroid and immune system function. In Hoola, that comes as 150 mcg of selenomethionine in the daily 10 g serve.
Which foods are highest in selenium?
Brazil nuts, poultry, red meat, eggs, cereals and grains all contain selenium naturally. Selenium is found naturally in many foods, especially foods that contain protein.
Can you get a selenium supplement in Australia?
Yes. Hoola is a Listed product on the Australian Register of Therapeutic Goods, AUST L 508472, with an ARTG start date of 8 August 2025 and Hoola Australia Pty Ltd as sponsor. It is manufactured in Australia by BJP Laboratories Pty Ltd in Yatala, QLD, with Australian laboratory testing.
