Health Deals Radar — June 4, 2026

June 4 brings 13 new brand-specific Vitacost promo codes in a single batch — more than any prior daily sweep in this tracking window. iHerb's 618KMH26 (26% off) confirmed expired today after an extended run; three fresh iHerb codes (EST26, PARADISE15, MAYAPP15) are now the top-priority picks. GNC extended Ghost's Birthday BOGO 50% through June 11, and new code PUMPAF unlocks $10 off creatine when bundled with a pre-workout. MyProtein's $9.99 creatine and 40% sitewide are unchanged. The Costco June+July book remains unreleased at Day 3+ delay; May book expires June 7 — three days left.

Expiry watch

Costco May book — 3 days left (expires June 7). Two health items still active from the May coupon book: Orgain Collagen Peptides + Probiotics at $23.99 ($6 off the $29.99 regular price) and Ensure Original Nutrition Shake at $28.99 ($8.50 off the $37.49 regular price). 1 Both apply automatically at the warehouse register with a Costco membership — no barcode to show.

Vitacost cluster expiring June 7 — act before the weekend. Three active sitewide-eligible codes — CYBERSMS20 (20%), SITESALE15 (15%), and LIFE20 (20%) — all expire June 7. 2 ALLSITEWIDE15 (15%) also expires June 7. Pick the highest applicable percentage for your cart.

Vitacost WKND1 and new Jun 4 batch (QUALIA25, ALLANCIENT, 20SOV, 20THINKBRAND, 15BADGER) — expire June 8. WKND1 is Jigsaw Health-only; the five new brand codes from today's batch cover Qualia (25% off), Ancient Nutrition (15%), Sovereign Silver/Copper (20%), Think Brand (20%), and Badger (15%). 2

Vitacost ANNIE15 — expires June 9. The long-running anchor code (ANNIE15, 15% off select orders, 37 verifications) expires Monday. 2 If you have a cart sitting idle, use it before the weekend rather than waiting until Sunday night.

iHerb MAYAPP15 — expires June 10. App-only (iHerb mobile app required), 15% off, 1 verification so far. 3 Lower confidence than EST26 given the single verification, but worth testing if you order via the app.

GNC PUMPAF — expires June 8. New today: $10 off GNC Creatine when purchased together with Beyond Raw LIT AF v2 pre-workout. 4 Six verifications already. This is a bundle-specific code — both items need to be in the cart.

iHerb 618KMH26 — confirmed expired. The 26% off 618 Early Access code (which had been holding unusually long) is now in DontPayFull's expired section with a June 4 cutoff date. 3 No replacement June sitewide code has appeared.

iHerb — 3 confirmed new codes, 16 active codes stable

Three codes not tracked in prior sweeps are confirmed active as of June 4: EST26 (20% off select wellness supplements, expires July 5, 13 verifications, last confirmed 7 hours ago), PARADISE15 (15% off select health supplements, expires July 9, 2 verifications — note: excludes US customers), and MAYAPP15 (15% app-only, expires June 10). 3

Two codes received fresh checkout confirmations today: DRBEST26 was verified by DontPayFull user abbeysinden on June 4, saving $4.53. KBF3096 (up to 40% off) was confirmed by user jaferaqsa on June 4. 3 All 16 previously tracked active codes remain on DontPayFull with stable verification counts, all confirmed within the last 24 hours.

US shoppers — priority order for today:

EST26 — 20%, expires Jul 5, 13 verifications (highest confidence)
DRBEST26 — 20%, expires Jul 5, checkout-confirmed today
KBF3096 — up to 40%, no expiry, checkout-confirmed today
NEW20 — 20%, new accounts only, expires Jul 5
GOLD60 — 10%, $60+ carts, no expiry, 929 verifications (reliable fallback)

iHerb allows one promo code per order. EST26 and DRBEST26 both offer 20%; test both and apply whichever accepts at checkout first.

Vitacost — 13 new brand codes in one batch

Multiple health supplement bottles on a white wood surface, overhead view — Vitacost added 13 brand-specific codes on June 4 — most capping at Jun 8 or Jun 15. AI-generated image

Thirteen brand-specific codes appeared on DontPayFull's Vitacost listing today, all added within roughly 15 hours of each other and each with one verification. 2 None have checkout-confirmed status yet — they're community-captured, not staff-verified. Treat them as likely-active until proven otherwise, and test at checkout before assuming they'll apply.

Code	Brand	Discount	Expires
`IRWIN`	Irwin Naturals	20% off	Jun 15
`MERCOLA`	Dr. Mercola	20% off	Jun 15
`NONGMO`	Non-GMO products	20% off	Jun 15
`TREETOTUB`	Tree to Tub	20% off	Jun 15
`ALLCABOO20`	Caboo	20% off	Jun 15
`20BARK`	Bark & Whiskers (pet wellness)	20% off	Jun 15
`PRIMA20`	Yerba Prima	20% off	Jun 15
`HAWAII`	Nutrex Hawaii	20% off	Jun 15
`ALLANCIENT`	Ancient Nutrition	15% off	Jun 8
`20SOV`	Sovereign Silver & Copper	20% off	Jun 8
`15BADGER`	Badger	15% off	Jun 8
`QUALIA25`	Qualia	25% off	Jun 8
`20THINKBRAND`	Think Brand	20% off	Jun 8

The Jun 8 codes (ALLANCIENT, 20SOV, 15BADGER, QUALIA25, 20THINKBRAND) have the tighter window; use these first if your cart includes any of those brands. The Jun 15 codes have more room but are still unverified — check DontPayFull in the next 24 hours for confirmation updates.

One carry-over to flag: BIONUTRITION (20% off Bio Nutrition products) has displayed "Expires tomorrow" on DontPayFull for five consecutive days, past its original June 1 expiry. 2 This is a data display anomaly — the actual code status at Vitacost checkout cannot be verified from aggregator data alone. Test it if your cart has Bio Nutrition items, but don't count on it.

GNC — Ghost BOGO extended to June 11, new creatine bundle code

GNC's Ghost Birthday BOGO 50% deal now shows two listings on DontPayFull — one with a June 10 expiry and one with June 11 — both verified 7 hours ago with three verifications each. 4 The June 11 entry represents an extension from yesterday's June 10 cutoff. GNC's homepage confirms the Ghost Birthday BOGO 50% Off sale for all users (no PRO membership required), covering the full Ghost line: protein, pre-workout, energy drinks, greens, hydration, and BCAAs. 5

BOGO 50% math: the discount applies to the lower-priced item. Two Ghost WHEY tubs at $54.99 each nets $82.49 for the pair ($27.50 saved, 25% off combined retail).

PRO Access BOGO 50% Mix-and-Match expanded to 11 brands as of this sweep, up from 10 reported yesterday: Optimum Nutrition, Ghost (also in everyone-eligible tier), Alani Nu, GNC AMP, Beyond Raw, GNC Pro Performance, Raw Nutrition, RYSE, Gorilla Mind, Axe & Sledge, and Alpha Lion. Expires June 8. 4

New code PUMPAF — $10 off GNC Creatine with simultaneous purchase of Beyond Raw LIT AF v2 pre-workout, expiring June 8. 4 Six verifications since it appeared. The code requires both items in the cart; it won't apply to creatine alone.

Premier Protein BOGO Free is gone as of June 3. 5 The banner remains on GNC's homepage but is marked "Ends 6/3." No equivalent offer has replaced it.

MyProtein — $9.99 creatine confirmed, new Creapure banner

White creatine monohydrate tub with $9.99 price tag, barbells blurred in background — MyProtein's Creatine Monohydrate Powder remains at $9.99 (auto 50% off, was $19.99). AI-generated image

MyProtein US is running 40% off almost everything sitewide with no promo code required, and Creatine Monohydrate Powder is $9.99 (auto-50% off from $19.99). 6 Both confirmed active on the June 4 homepage scan.

A new secondary banner appeared today: "Up to 50% off Creapure" — promoting Clear Whey Isolate at $44.95 and premium creatine under the Creapure brand (Creapure is a patented creatine monohydrate from Germany). 6 This banner was not present in prior monitoring runs. Impact Whey Protein is priced at $16.99 and Impact Whey Isolate at $29.99 at the current 40% discount.

Free shipping threshold: $99 (per the June 3 update). The $9.99 creatine alone falls below the floor; a second item at 40% off typically bridges the gap without difficulty.

Weekly spotlight items at 40% off: Creatine Gummies, Electro X HYROX Stick Pack, Essential Omega-3 Softgels, 100% Citrulline Malate Powder. 6

BPN — 25% off new subscriptions, no June sitewide code (Day 6)

Bare Performance Nutrition (BPN) has not released a June 2026 sitewide promo code. SPRINGFIT expired May 31; today is Day 6 without a replacement. 7 The standing code BPNTEN (10% off) remains the only general discount available.

BPN's current primary offer is 25% off all new subscriptions — no code needed, applied at checkout when subscribing to a recurring order. The brand is also promoting a new product: the Maple Cinnamon Go Bar, 34g carbs, 200 calories, with simple ingredients and an endurance / long-run positioning. 7 The Go Bar is a product launch, not a discount event.

If BPN follows its historical pattern of releasing codes after a short gap following a major holiday period, a new code may surface this week — but nothing has appeared across any aggregator as of this afternoon's scan.

Slickdeals pick — echinacea at $4.29

Echinacea supplement bottle with orange capsules scattered on white marble surface — Nature's Bounty Echinacea 400mg 100-count at $4.29 via Amazon S&S + coupon. AI-generated image

Nature's Bounty Echinacea 400mg, 100 capsules — $4.29 (was $7.69, 44% off). Posted June 4 by Slickdeals Staff, Deal Score +3. 8 The stack: Amazon current price $6.60 → clip the 30% on-page coupon → add via Subscribe & Save → final $4.29. Product has 4.8 stars from 9,581 Amazon reviews. Prime required for free shipping, or $35+ order total.

The previous low on this item was $5.00 (Slickdeals, April 9, 2026). At $4.29, this is below that prior mark. No stated end date on the coupon.

How to get it: log into Amazon, find the product, clip the 30% coupon on the listing page, then check out through Subscribe & Save. You can cancel the subscription after the first delivery.

Costco — June+July book still unreleased (Day 3+)

The Costco June+July 2026 Coupon Book has not been published as of 14:00 ET today. 1 Costco Insider lists it with a June 15–July 19 effective window (earlier reports from Instagram and RedFlagDeals had suggested June 8–July 5 — the date conflict is unresolved). The book page itself does not exist; only a subscription prompt is shown.

This is now three days past the expected release window based on the May book's publication pattern. No details of the book's health-related coupons are available until it publishes.

What's still actionable from the May book before June 7: 1

Orgain Collagen Peptides + Probiotics: $23.99 (regular $29.99 — save $6.00)
Ensure Original Nutrition Shake: $28.99 (regular $37.49 — save $8.50)

Whey protein drought — Day 5

No whey protein powder deals appeared on Slickdeals supplements or across four scanned Reddit communities (r/AmazonofDeals, r/frugal, r/deals, r/Supplements) in the June 3–4 window. 9 All visible Slickdeals supplement discounts are in magnesium, echinacea, NAC, and vitamin categories. A June 4 r/frugal thread by u/BlueCollarBalling noted that MyProtein has raised prices and reduced package sizes from the prior 11 lb bag format, with the poster now using Aldi's store brand as a substitute. 10 MyProtein's $9.99 creatine monohydrate remains the best protein-category deal available at any major retailer today.
