# ThyraGlow naming decision · 2026-09-29

**Decision: keep ThyraGlow as the working brand.** Reason: it is the only candidate that says both halves of Cody's brief in two syllables (Thyra = the woman's thyroid word; Glow = the mirror payoff the dossier proves women care about), with thyraglow.com free and no clear conflict found. Trademark is NOT cleared (see risks).

Skills consulted: naming-strategist framing (target = women 35-60, thyroid complaints they name first: exhausted, puffy, hair/brow shedding, dry skin, weight, "will I look like me again?"). KNB design query run (`--role sales --section hero`, pack design-ffec10c37470): returned only generic layout lessons (KNB-P01/P05/P06 "choose one coherent visual family"); no naming evidence, so naming is our judgment.

| # | Name | Rationale | Fit to women's thyroid complaints | Sound / spelling | Domain (GoDaddy check 2026-09-29) | Risks |
|---|------|-----------|-----------------------------------|------------------|-----------------------------------|-------|
| 1 | **ThyraGlow** | Thyra + Glow, woman's-thyroid word + beauty payoff | Hair, skin, puffiness, tired eyes, "glow back"; also energy/mood ("glow from within") | Easy: thigh-ra-glo. Spelling "Thyra" is guessable | thyraglow.com available (also .co, .shop, .store) | "Glow" is crowded in beauty; TM search needed in class 5; could read "skin product" (mitigated by descriptor line) |
| 2 | ThyraBloom | Thyra + Bloom, feminine, floral | Softer, hair regrowth/brows imagery | thigh-ra-bloom, easy | thyrabloom.com available | Floral pull fights the sea-plant story; "bloom" is used by many supplement brands |
| 3 | Thyriva | Coined, Latin-feel ("thyro" + "viva") | Vitality/energy; little on looks | thigh-REE-va; pronunciation may split (thi-RIE-va) | thyriva.com available | Nothing to picture; reads pharma; weaker on beauty angle |
| 4 | Selkie Thyroid | Sea-folk myth (women of the sea) | Strong sea story, mystique | Distinct, memorable | selkiethyroid.com available | "Selkie" is an existing apparel brand; myth is off-message for a science-flavoured formula; "Thyroid" in the name is a disease-claim risk |
| 5 | FemiThyra | Feminine + Thyra, literal | Says "for women" bluntly | fem-ee-thigh-ra, clinical | femithyra.com available | Sounds like a feminine-hygiene / hormone drug; narrows to gender not benefit |
| 6 | **Thyralune** (new) | Thyra + lune (moon): cycles, hormones, calm | Perimenopause/hormone-cycle women; night/sleep | thigh-ra-loon, soft | thyralune.com available | Moon/cycle angle drifts from the visible-beauty payoff; "lune" pronunciation |

Also checked: thyrasea.com, thyramarin.com, seathyra.com (all available; sea-name family, rejected because they sound like seafood/ocean-products, not a women's brand).

## Verdict
ThyraGlow beats the field on payoff clarity (Glow) and on sound. The one real weakness is trademark/category crowding, which only a USPTO search settles. **Client action: run a knockout + counsel search (classes 5 and 35) before buying media; register thyraglow.com now (cheap, available).** Fallback if ThyraGlow is blocked: ThyraBloom, then Thyralune.

## Descriptor and naming rules
- Always pair the brand with the descriptor "Complete Thyroid Support for Women" (keeps the legacy "Complete Thyroid" search term and stays structure/function).
- Product line: ThyraGlow Complete Thyroid Support (front end) · ThyraGlow Moringa · ThyraGlow Omega-3X · ThyraGlow Probiotic. Mechanism: "the ThyraGlow Matrix".
- Wordmark is written lowercase "thyraglow" on label/logo, "ThyraGlow" in running copy.
- The old name "Complete Thyroid" (Science Natural Supplements) stays a hub alternate.

## Tagline options
1. Thyroid support for women who want their glow back. (SPINE default, keep)
2. The thyroid formula made for women.
3. Your glow starts with your thyroid.  [use only as brand line; not a promise]
4. From the sea, for her.
5. Support your thyroid. Meet your reflection.
