🌸 TL;DR
Selenium might be tiny, but it’s mighty. This essential trace mineral supports your thyroid, hormones, immune system and even your skin and hair. It helps your body fight oxidative stress (aka cell damage), keeps your energy steady and plays a key role in reproductive health. You’ll find it in foods like seafood, eggs, seeds and Brazil nuts – just a few a day can cover your needs. No wonder we made sure selenium stayed in the Gigi blend!
With the upcoming flavour updates, we’ve been talking about selenium a lot! We’ve mentioned how it’s such a vital part of our blend for female hormonal health – but we’ve never gone into detail about just how good it really is.
Selenium might be a small nutrient, but it plays some seriously big roles in the body. From supporting reproductive health and hormone balance to keeping your thyroid and immune system running smoothly, this trace mineral works quietly behind the scenes to keep you feeling your best (so it’s no wonder we made sure it’s in the blend!).
What is Selenium?
Selenium is a trace mineral, which means your body only needs a small amount – but don’t let its size fool you, it’s essential for keeping your body running at its best.
One of its superpowers? Antioxidant protection. Selenium is a crucial component of enzymes called selenoproteins, which help neutralise free radicals – those unstable molecules that can damage your cells and speed up the ageing process. These selenoproteins also play important roles in thyroid hormone metabolism, DNA synthesis and immune response.
So while you might not hear about selenium as often as zinc or iron, it’s quietly working to keep your metabolism, energy and cellular health optimised.
Food & Selenium
Selenium is found in a variety of both plant and animal-based foods. The amount of selenium in animal products depends on the selenium content of the animals’ diet.
Good animal sources include:
- Seafood (salmon, tuna, prawns)
- Meat & Poultry
- Dairy Products
- Eggs
For plants, selenium content varies depending on the soil they’re grown in and the plant’s natural ability to absorb it. Some plants are particularly rich in selenium, often called “selenium accumulators.”
Rich plant-based sources include:
- Brazil nuts & cashew nuts
- Sunflower seeds, flaxseeds & chia seeds
- Lentils & kidney beans
- Mushrooms
Role of Selenium in the Body
Even though your body only needs a tiny amount, selenium is busy behind the scenes keeping everything running smoothly. From supporting your thyroid and hormone balance to boosting immunity and protecting your cells from damage, this little mineral has some seriously big responsibilities. Here’s a closer look at the key ways selenium helps you feel your best every day.
🦋 Supports Thyroid Health
Your thyroid is basically your body’s energy hub, regulating metabolism, mood and hormone balance. Selenium is needed for the conversion of thyroxine (T4) into the active thyroid hormone triiodothyronine (T3). Without enough selenium, this conversion process slows down, which can leave you feeling sluggish or fatigued.
🛡️ Boosts Immunity
Selenium helps regulate the activity of immune cells and enhances your body’s ability to defend itself against viruses and bacteria. It’s antioxidant properties help in reducing inflammation and improving immune resilience.
⚡ Protects Cells
As an antioxidant, selenium fights off free radicals, which protect your cells from oxidative stress. This not only supports long-term health but also helps your body recover faster from stress, exercise or illness.
Why Selenium Matters for Women?
Selenium isn’t just any mineral — for women, it plays a starring role in keeping hormones, energy, and overall wellbeing in balance. From supporting reproductive health and fertility to protecting your skin, hair, and nails, this tiny nutrient makes a big difference.
⚖️ Hormonal Balance
Selenium supports the thyroid's production of hormones that influence everything from metabolism and mood to menstrual cycle regulation. A balanced thyroid = balanced hormones.
🌸 Fertility & Reproductive Health
Adequate selenium levels are linked to better egg quality and reduced oxidative stress in reproductive tissues. During pregnancy, selenium also helps protect both mother and baby by supporting immune and thyroid function.
✨ Skin, Hair and Nails
Because of its antioxidant role, selenium helps protect the skin from oxidative stress (think pollution, UV exposure, and daily wear). It’s also vital for tissue growth and repair, promoting stronger nails and healthy hair.
⚡ Mood & Energy
Low selenium levels have been linked to fatigue and low mood, so keeping your levels optimal can help you feel more energised and balanced day-to-day.
The Takeaway on Selenium
It might not be the most talked-about nutrient, but selenium is a small mineral with a big mission – protecting your cells, balancing your hormones and keeping your energy steady.
That’s why we made sure it stayed in our PMS & Hormone Balance Blend. It’s one of those quiet heroes that helps you feel like your best, most balanced self – inside and out.
