What it supports

+
Your body's own antioxidant defence
Selenium is built into glutathione peroxidase, one of the enzymes your cells use to manage oxidative stress from the inside.
+
Thyroid hormone conversion
The thyroid holds more selenium per gram than any other tissue, and the enzymes that convert thyroid hormone depend on it.
+
Everyday immune readiness
Selenium supports normal immune cell function — part of the quiet background work of staying well.
+
Skin, hair and nails
Fast-renewing tissues feel a shortfall first, which is why selenium status shows up there.
+
Reproductive health
Selenium contributes to normal reproductive function in both men and women.
+
Three months in every bottle
Ninety capsules at one a day. Three months of steady antioxidant support, without thinking about it.

Inside the formula

Albion selenium glycinate

Selenium is a trace mineral, which means the gap between too little and too much is narrower than for almost anything else you take. That makes the form matter. Selenium glycinate is selenium chelated to glycine, the smallest amino acid, so it travels the amino-acid absorption pathway rather than arriving as a loose salt. We dose it at 200 mcg — the amount used across the antioxidant and thyroid literature — in a single capsule, ninety to a bottle.

Customers say

Summarised from customer reviews.

Reviewers consistently describe this as a simple, uncomplicated supplement — several say they wanted selenium on its own rather than inside a multivitamin. Capsule size is the single most mentioned detail, with many calling it one of the smallest they take, and no aftertaste or digestive upset is widely reported. Results are the least discussed aspect: the lower-rated reviews are not about problems but about difficulty judging a trace mineral's effect after one bottle.

Frequently asked
questions

How do I know what's on the label is in the bottle?
Trust should be verifiable. Every batch we produce is tested by an independent laboratory, and the certificate of analysis for your exact lot is published on this page — potency, heavy metals, microbials. Testing begins the moment a raw material arrives, continues through production, and no batch is released until every result clears. The label is a claim. The COA is the proof.
How do you choose your ingredients and doses?
We formulate from peer-reviewed clinical research and dose to match it. We select the highest-grade material available for each ingredient, in the form the body absorbs best, and where a patented or branded form is the one that has actually been studied, that is the one we use. Every active appears at its exact amount, with no proprietary blends and nothing added that doesn't need to be there.
Where are CoreLabs supplements made?
In our own cGMP-certified facility in California's Central Valley. Manufacturing in-house means quality is our responsibility at every step rather than a supplier's promise. Raw materials are purchased through established US suppliers who import and qualify them, and every material is tested against our own specification before it enters production — wherever it originated.
Why are CoreLabs supplements more expensive?
Because of what goes in. We buy the highest grade of each raw material, in the most absorbable form, and we work with the branded and patented ingredient houses whose material the clinical research was actually run on — names like Lonza, Albion, RIBUS, Sabinsa and Indena. Wherever possible those materials are made domestically. Our capsules are titanium-dioxide free. Then it is made in our own facility and third-party tested batch by batch. Every one of those choices costs more than the alternative, and the price reflects it. Anyone can claim quality — we publish ours.
Why glycinate rather than another form?
Chelating selenium to glycine means it travels the amino-acid absorption pathway rather than arriving as a loose inorganic salt. For a trace mineral where the useful range is narrow, that consistency matters.
Why 200 mcg?
It is the amount used across most of the antioxidant and thyroid research on selenium. One capsule covers it.
Can I take too much selenium?
Yes — selenium has a genuinely narrow useful range, which is why we dose it at 200 mcg and disclose it exactly. Do not stack it with other selenium-containing products without talking to a healthcare professional.
Should I take it with food?
Yes, one capsule daily with food.
How long does a bottle last?
Ninety capsules at one a day is three months.
