How it works?

Selenium is essential for converting T4 (inactive thyroid hormone) into T3 (the active form your body uses). Our L-Selenomethionine is the same form found naturally in food — absorbing at over 90%. One tiny coconut oil softgel daily gives your thyroid the raw material it's been missing.

How long before I see results?

Most customers notice reduced puffiness and warmer hands within 2-4 weeks. Brain fog and energy improvements typically follow by week 3-4. Hair shedding slows around 4-8 weeks. Thyroid antibody changes show on bloodwork at 3-6 months.

      • "I thought my thyroid was ruining my life. Turns out it was missing this."

        I've had Hashimoto's for 5 years. Puffy face every morning, exhausted by lunch, hair everywhere except my head. My endocrinologist suggested selenium but never said which form mattered. Found this one — L-Selenomethionine with coconut oil. By week 3, the puffiness started going down. By month 2, my hair stopped clogging the drain. I don't feel "cured" but I feel like myself again.

        Sarah M.

      • "My labs finally moved. My doctor finally listened."

        TPO antibodies sat at 400+ for three years. Medication didn't budge them. Started taking this daily, changed nothing else. Three months later my antibodies dropped to 240. My endocrinologist pulled up the chart and asked what I did differently. One tiny softgel. That's it.

        Esther A.

      • "I quit coffee. Not on purpose — I just didn't need it anymore."

        The 2pm crash was my whole identity. Coffee, energy drinks, naps in my car on lunch break. Started this selenium and by week 2 I noticed I wasn't reaching for the coffee pot at 10am. By month one I stopped buying it altogether. The energy isn't jittery — it's just steady. Like how I remember feeling 10 years ago.

        Patricia L.

      • "I stopped avoiding mirrors in the morning."

        The puffiness was the worst part. I'd wake up looking like I cried all night. My rings wouldn't fit. My face looked swollen. Two weeks on this and my husband noticed before I did — he said I looked less tired. By week 4 my rings were loose again. Such a small thing but it gave me my confidence back.

        Frequently Asked Questions

        What is selenium and why do I need it?

        Selenium is an essential trace mineral your body can't produce on its own. Your thyroid contains the highest concentration of selenium in your entire body — it's required to convert T4 (inactive thyroid hormone) into T3 (the active form your body actually uses). Without enough selenium, that conversion stalls and you're left with brain fog, fatigue, cold hands, puffiness, and hair loss. Modern farming has stripped it from our soil, which is why most women are deficient without knowing it.

        What makes Vitalyn® different from other selenium brands?

        Three things. First, we use L-Selenomethionine — the same form found naturally in food that absorbs at over 90%. Most cheap brands use sodium selenite which absorbs at only 50% and has been linked to oxidative stress. Second, our softgels are infused with coconut oil to enhance absorption and eliminate the stomach issues that come with dry powder capsules.

        How do I take it?

        One tiny softgel per day with food. It's smaller than your pinky nail. The coconut oil inside helps with absorption so taking it with any meal works. That's it — 5 seconds a day.

        How long before I see results?

        Most customers report warmer hands and less puffiness within 2-3 weeks. Brain fog and energy improvements typically follow by week 3-4. Hair shedding slows around 4-8 weeks. If you're tracking thyroid antibodies, clinical studies show TPO levels can drop significantly within 3-6 months.

        Will it upset my stomach?

        No. This is one of the most common complaints about other selenium brands — nausea, weird burps, stomach cramps. Our coconut oil softgel eliminates that. 89% of selenium softgel users report zero stomach issues compared to dry powder capsules.

        Can I take this with my thyroid medication?

        Yes. Selenium supports your medication by helping convert the T4 it provides into the T3 your body actually uses.

        What if it doesn't work for me?

        We offer a 30-day money-back guarantee. If you don't feel a difference, email us and we'll refund you. No questions asked. We're confident because the science backs it and our customers keep reordering.
