The Duality
Every hormone problem is one of two things
Like every system on this site, hormones have a deficiency side and a toxicity side — and most real-world patterns are some mix of both at once.
Too little, can't build it
Thyroid hormone needs iodine as a literal building block and selenium to activate it. Sex hormones are built from cholesterol through a pathway that runs on zinc, magnesium, and B-vitamins. Cortisol production needs the adrenal glands' own mineral reserves. Without the raw materials, the gland cannot produce or regulate normally — no matter how "healthy" it otherwise is.
Too much, or thrown off
Endocrine-disrupting chemicals from plastics, household products, and food packaging can occupy or interfere with hormone receptors. Chronic stress keeps cortisol elevated long past when it is useful. Iodine's halogen cousins — fluoride, bromide, chlorine — can displace it at the tissue level. This is the excess-and-disruption side of the same coin.
The Core Thesis
Hormones are downstream of nutrition, gut, and minerals
The thyroid, the adrenal glands, and the ovaries and testes are organs like any other — they make and regulate hormones using optimal nutrients as raw material, not out of thin air. When the conversation skips straight to "fixing" a hormone level, it usually skips the more useful question: does this organ have what it needs to make, convert, and clear that hormone in the first place? That question always leads back to the same three places.
Gut Health
The raw materials for hormones have to actually be absorbed before any gland can use them. A compromised gut lining, low stomach acid, or dysbiosis can mean the iodine, zinc, and B-vitamins in your food never make it to the tissues that need them — and the gut's estrobolome shapes how efficiently the body clears hormones it has already used.
See how absorption worksNutrition Foundation
Every hormone in the body is built from something you ate. Cholesterol, zinc, B5, B6, and vitamin C build the sex-hormone pathway; iodine and selenium build and convert thyroid hormone. A diet genuinely short on these raw materials leaves the glands undersupplied no matter how well they're otherwise functioning.
The nutrition foundationMinerals — Measured, Not Guessed
Iodine, selenium, magnesium, and zinc are the cofactors hormone-producing organs run on, and mineral status is one of the more common gaps we see when people actually test rather than assume. OligoScan and the rest of the Big Three read where you stand before anyone reaches for a supplement.
Measure your mineralsMood Is Part Of This System
Cortisol, thyroid hormone, and the nervous system talk constantly
Low thyroid hormone slows cognitive processing and flattens mood. Chronically elevated cortisol produces the "wired but tired" pattern — anxious, irritable, unable to settle. Sex hormones modulate neurotransmitter activity directly. None of this is separate from how the nervous system regulates itself day to day — it is the same system, described from a different angle.

Sleep is when cortisol and melatonin set their rhythm
Cortisol and melatonin are hormones, and their daily rhythm — cortisol rising in the morning, melatonin rising at night — is one of the clearest hormone patterns you can actually observe in yourself. Sleep loss flattens that curve within days, suppressing growth hormone, testosterone, and thyroid hormone conversion at the same time. Hormones and sleep are two separate, full pages on this site for a reason, but they meet directly right here.

When food alone isn't covering the gap
Food comes first. A foundation of iodine-rich seafood or seaweed, a couple of Brazil nuts for selenium, and a diet that doesn't restrict dietary fat and cholesterol covers most of this ground for most people. When it doesn't, these are the targeted nutrients we point to — always described in terms of what they support, never what they fix.
Estera — sequential hormone-metabolism support
Pharmanex
Estera Phase II ("Estera 2")
A Pharmanex formula from the hormone-support line, positioned to support the body's own normal hormone metabolism and balance — not to replace, override, or "fix" a hormone level.

Estera Phase III ("Estera 3")
The second phase in the same sequential system, taken alongside or after Phase II per the current label. Same structure/function framing applies: support for the body's own hormone metabolism and normal balance.

Commodity nutrient
Iodine
The literal building block of thyroid hormone — T4 carries four iodine atoms, T3 carries three. Supports normal thyroid hormone production; it does not treat any thyroid condition.
A commodity nutrient with no in-house product. Widely available iodine brands require a dealer account, so none is named here yet.
Search on AmazonCommodity nutrient
Selenium
Runs the deiodinase enzymes that convert storage T4 into active T3, and helps protect thyroid tissue from the hydrogen peroxide generated during hormone synthesis. Supports normal thyroid hormone production, within a normal daily intake.
Commodity nutrient, no internal or Nu Skin-exclusive product. LifePak already provides both iodine and selenium as part of its broader foundation — see the product page for current amounts.

Pharmanex
Cortitrol
An evening blend of magnolia bark, L-theanine, phosphatidylserine, and plant sterols that supports the body's normal, healthy cortisol rhythm — the stress hormone that, left switched on, drags on sleep, mood, and the wider hormone system. Supports a normal stress response; it does not treat anxiety or any condition.
See CortitrolCommodity nutrient
Myo-Inositol
The myo form specifically — studied for supporting healthy insulin signaling and normal ovarian and menstrual-cycle function. Supports normal hormone balance; it does not treat PCOS or any condition.
The myo form specifically, not other inositols. A preferred brand will be named here.
Search on AmazonStructure/Function Only
Every product on this page is framed as support for the body's own normal hormone production and balance — never as something that balances, fixes, treats, or cures a hormone condition. Iodine and selenium support normal thyroid hormone production specifically because they are direct cofactors in that process, not because they correct any diagnosis. Medication and dosing changes are always made with and by your own provider.
Nothing Works Alone
Optimal nutrients, stacked as a system, is what changes longevity
No single nutrient runs the hormone system by itself. Iodine without selenium leaves T4 unconverted to active T3. Selenium without adequate antioxidant status leaves the thyroid exposed to the oxidative byproducts of its own hormone synthesis. Zinc and B-vitamins without cholesterol have nothing to build sex hormones from. This is why LifePak, which already carries iodine and selenium as part of its broader mineral and antioxidant base, is the foundational layer underneath a targeted product like Estera — and why measuring first, with OligoScan, tells you whether a targeted nutrient is actually the gap worth closing. Foundational nutrition covers the broad base; targeted support closes a specific, measured gap on top of it. Stacking the two — not swapping one for the other — is the system that compounds over years, not weeks.
