Give your thyroid, metabolism, and immune system the micronutrients to do their best work.* Selenium is a trace mineral your body needs for energy, immunity, and thyroid hormone conversion (it helps convert T4 to T3).* BodyBio's liquid selenium supplement is highly bioavailable and delivered in a clean, ionic liquid form.* That means fast absorption and precise dosing with no fillers or unnecessary additives.* 

How Liquid Selenium Supports Your Body

  • Thyroid Function and Hormone Balance: Selenium converts T4 to T3 (the active thyroid hormone).* Use it to support healthy thyroid function and the metabolic activity that depends on it.*
  • Cell Protection: Selenium is an antioxidant cofactor, which means it activates an enzyme that helps protect cells from damage and stress.* That means a healthy immune system.*
  • Immune Support and Cell Resilience: Selenium contributes to immune function and cellular health, helping the body build resilience against everyday mental and physical stress.*
  • Highly Absorbable Ionic Form: The ionic liquid format means selenium is already dissolved in solution and ready for the cells to use, making it more bioavailable than standard capsule selenium supplements.*

Selenium is a trace mineral that helps assists in regulateting the body's core systems, like the thyroid, immune, and endocrine systems.* We only need it in small amounts, but selenium’s ability to support cellular energy, protect cells from stress, and play a role in converting thyroid hormones shouldn’t be overlooked.* BodyBio’s liquid selenium supplement delivers this critical nutrient in a highly bioavailable ionic form.

The Trace Mineral In Charge of Thyroid Health

In periods of high physical or mental stress, the body may use nutrients at a faster rate.* A selenium supplement helps keep those nutrient stores full, especially for people who need metabolic, cognitive, or hormone support.* It’s practical to add to your supplement routine if you don’t eat much seafood, your gut struggles to absorb nutrients, or you live in an area where selenium is depleted from soil.*

As a mineral supplement, add 1.25 mL to water or juice daily, or more as directed by a licensed Healthcare Practitioner. 

Shake well. Do not refrigerate.

    Noticing more alertness

    I’m on my second bottle of selenium and I really think it’s working. I’m replacing a glandular with it that I have been taking for a number of years.

    I’m a big fan of Body bio products that I was introduced to indirectly by a nurse practitioner here in Santa Fe.

    I’m in for the long haul because I know it takes a while for things to kick in. Love the company! 🙏🏽

    Excellent

    The Selenium in combination with taking liquid Zinc and Iodine has made a great difference for me. My mind has been clearer and able to remember things. I have also noticed that my concentration is more on point. I am sleeping better and waking up refreshed...and this is after only taking the supplements for a week!

    I am glad that I found something that works for me.

Frequently Asked Questions

A liquid selenium supplement is more bioavailable than a capsule or tablet because the ionic mineral is already dissolved and ready for the cells to use.* There’s no need for the digestive system to break down a tablet shell or fill matrix first. 

This format is valuable for people with poor gut function, low stomach acid, or general absorption issues, which can limit how much selenium your body actually uses.* The convenient dropper also allows for flexible, individualized dosing, which is important for a trace mineral like selenium, where precision matters.

Selenium is used in the process that converts inactive thyroid hormone (T4) into the active form (T3).* This is the hormone your body uses to regulate metabolism, energy levels, and cellular function across virtually every tissue.*

Selenium also supports healthy thyroid hormone metabolism by activating the enzyme that protects the thyroid gland from oxidative damage.* This is why selenium supplements for thyroid health are widely used, especially in a clinical setting.

Yes, selenium’s role in thyroid hormone production, mitochondrial function, and immune health makes it a good choice for energy.* Suboptimal selenium levels can contribute to persistent tiredness or low stamina.* Replenishing selenium through a highly absorbable, bioavailable selenium supplement can give the body the trace mineral support it needs for consistent energy, mental clarity, and an improved mood.*

Yes, selenium and iodine work together to support healthy thyroid hormone production and to protect cells from stress.* Iodine provides raw material for thyroid hormone synthesis, and selenium activates the enzymes that convert thyroid hormone to its active form.* Balancing both trace minerals is important, especially when you’re supplementing iodine.

"Ionic" means the mineral is in its charged, water-soluble form and ready for immediate absorption without digestive breakdown.* Ionic liquid minerals are bioavailable and effective even for those with poor gut function, low stomach acid, or chronic digestive issues that often limit absorption.* BodyBio’s ionic selenium is paired with an ionic sea minerals concentrate for added trace mineral support.

BodyBio Liquid Selenium is helpful for anyone working on thyroid function, hormone balance, or hormone metabolism, especially those whose diet is low in selenium-rich foods like Brazil nuts, seafood, and whole grains.* It’s also a strong fit for those dealing with fatigue, brain fog, weakened immune function, or oxidative stress that may be linked to suboptimal selenium levels.* Selenium supplements for women are recommended during periods of hormonal change, when thyroid hormone balance becomes especially important.*

Yes, when taken as directed, selenium is generally well tolerated for daily, long-term use, particularly at the 300 mcg per serving dose. That said, selenium has an upper safe intake limit, so anyone taking high-dose selenium for extended periods, combining multiple selenium-containing supplements, or managing thyroid conditions should work with a healthcare practitioner to monitor and adjust as needed.*
