Health Deals Radar — June 6, 2026

The biggest single-day code expiry since this tracking began hits tomorrow, June 7 — five codes across iHerb and Vitacost expire simultaneously, and the Costco May coupon book closes at end of business. If you use any Vitacost sitewide code or the iHerb GCC code, today is your last window. There's also one genuinely good news item: ALLSITEWIDE15 (Vitacost 15% sitewide) reappeared on DontPayFull after vanishing June 5 — it's back with a June 7 deadline, and it's the highest-value code in the cluster. On the supply side, a Six Star Whey BOGO 80% deal on Amazon technically ended a 7-day whey drought on Slickdeals, though premium brands (Optimum Nutrition, Dymatize, Isopure) are still absent.

iHerb MAY26HH (15% heart health), tracked since June 5 with a June 10 expiry, expired today instead — either the expiry was shortened or the original date was wrong. Watch for a replacement JUN26HH code.

Coverage window: June 5, 2:50 PM ET → June 6, 2:00 PM ET.

Today's expiry cliff at a glance

Five codes drop off tomorrow. Prioritize by verification confidence:

Code	Retailer	Discount	Expires	Verification signal
`ALLSITEWIDE15`	Vitacost	15% sitewide	Jun 7 ⚠️	5 verifications on DPF; single-source only
`LIFE20`	Vitacost	20% off	Jun 7 ⚠️	Used 7h ago (Jun 6 morning)
`SITESALE15`	Vitacost	15% off	Jun 7 ⚠️	10 verifications, staff-verified
`CYBERSMS20`	Vitacost	20% off	Jun 7 ⚠️	8 verifications, last tested 3 weeks ago
`OM183`	iHerb	10% off (GCC only)	Jun 7 ⚠️	21 verifications, last confirmed 13h ago

Also expiring tomorrow: Costco May book (Orgain $23.99, Ensure $28.99) — warehouse register auto-applies, no code needed.

Vitacost — four codes expire tomorrow, `ALLSITEWIDE15` is back

Countdown ticket stubs showing tomorrow's Vitacost code expiry cluster: ALLSITEWIDE15, LIFE20, CYBERSMS20, SITESALE15 — Four Vitacost codes expire June 7 — use at least one today. 1

ALLSITEWIDE15 (15% off sitewide) is back on DontPayFull with five community verifications and a June 7 expiry after disappearing from the June 5 sweep. 1 It's the only 15% sitewide code in the current Vitacost stack and carries the broadest coverage. That said: DontPayFull is the only platform currently showing it — Google returns zero results, and SimplyCodes remains offline. Treat it as single-source verified rather than fully confirmed; test at checkout.

LIFE20 (20% off) is the most recently verified code in the cluster — a shopper used it about 7 hours before this sweep. 1 SITESALE15 (15% off) has 10 verifications and is staff-verified. 1 CYBERSMS20 (20% off) is the weakest of the four — its last successful test was three weeks ago (May 14), so run it last if the others fail. 1

CouponFollow (a coupon aggregator independent of DontPayFull) independently confirms a Jun 7 expiry cluster on Vitacost — a 25% off code and 15% off Ancient Nutrition both expire tomorrow — which corroborates the June 7 date for this batch. 2

Vitacost allows one code per order. Priority order for today:

LIFE20 — 20% off, most recently verified
ALLSITEWIDE15 — 15% off sitewide, broadest coverage (test first; single-source)
SITESALE15 — 15% off, staff-verified fallback
CYBERSMS20 — 20% off, use last (stale verification)
TEXT10 — $10 flat off, no expiry — outperforms 20% codes on carts under $50

BIONUTRITION update: This 20% Vitacost code has been showing an anomalous state for ~7 days — it was looping "expires tomorrow" for nearly a week, showed "expires today" on June 5, and now lists no expiry date at all with a single stale verification. Treat as dead. 1

WKND code update: WKND1 (30% off Jigsaw Health, a magnesium supplement brand) was replaced by WKND2 (25% off Olympian Labs, a general supplement brand) around June 5. Discount dropped from 30% to 25%; the swap also changed the applicable brand. Both versions expire June 8. 1

Vitacost codes beyond June 7

ANNIE15 (15% off, 37 lifetime verifications) expires June 9 — it's the most-verified Vitacost code in this tracking period, last confirmed May 30. 1 The Jun 4 brand batch (13 codes) all survived intact:

Code	Brand	Discount	Expires
`QUALIA25`	Qualia	25% off	Jun 8
`20SOV`	Sovereign Silver/Copper	20% off	Jun 8
`ALLANCIENT`	Ancient Nutrition	15% off	Jun 8
`15BADGER`	Badger	15% off	Jun 8
`HAWAII`	Nutrex Hawaii	20% off	Jun 8
`WKND2`	Olympian Labs	25% off	Jun 8
`IRWIN`	Irwin Naturals	20% off	Jun 15
`MERCOLA`	Dr. Mercola	20% off	Jun 15
`NONGMO`	Non-GMO Favorites	15% off	Jun 15
`PRIMA20`	Yerba Prima	20% off	Jun 15
`20BARK`	Bark & Whiskers (pet)	20% off	Jun 15
`ORIGINS15`	Healthy Origins	15% off	Jun 15
`VE601M`	Select capsules	20% off	Jun 13
`20SELECTLIFE`	Active lifestyle/fitness	20% off	Jun 11
`MAY26HH` (Vitacost)	Unspecified health	15% off	Jun 8
`30OURBRANDS`	Vitacost store brands	30% off	Not listed
`TEXT10`	Any order	$10 off	No expiry

iHerb — OM183 (GCC only) expires tomorrow; MAY26HH closed early

iHerb OM183 (10% off, Gulf Cooperation Council countries only) expires June 7, last confirmed working about 13 hours before this sweep — user reis_alyson saved $8.75 on June 6. 3 If you're shopping from a GCC country, this is the last chance to use it.

MAY26HH (15% off heart health supplements) showed a June 10 expiry in yesterday's sweep but is now in the expired section on DontPayFull — it closed June 6. 3 Whether iHerb shortened the window or the original date was wrong isn't clear; the MAY26 name suggests it was a May 26 batch code, and a mid-June expiry would have been unusually long for that format.

Two new geo-restricted codes appeared today: JUNMBO26 (24% off, Japan only, expires Jun 12) and JNKFES66 (22% off, South Korea only, expires Jun 12). 3 Neither applies to US orders.

iHerb active codes — US shoppers

Code	Discount	Applies to	Expires	Verifications
`EST26`	20% off	Select supplements	Jul 5	13 (last Jun 4)
`NEW20`	20% off	First order only	Jul 5	737 (last Jun 6)
`DRBEST26`	20% off	Doctor's Best brand	Jul 5	13
`LEC9737`	15–20% off	Select orders	No expiry	262 (last Jun 6)
`KBF3096`	Up to 40% off	General	No expiry	194
`GOLD60`	10% off	Orders $60+ ($50 max)	No expiry	934 (last Jun 6)
`JUN26PRO`	15% off	Probiotics	Jun 17	2 (last Jun 6, 12h ago)
`MAYAPP15`	15% off	App orders only	Jun 10	1
`PARADISE15`	15% off	Select, US excluded	Jul 9	2

iHerb accepts one code per order. EST26 at 20% through July 5 with 13 verifications is the strongest US option. GOLD60 (10% off $60+ orders, 934 verifications, no expiry) is the most reliable fallback for any cart that doesn't trigger EST26.

GNC — Ghost BOGO 50% through June 10; major Jun 8 cluster

Supplement tubs on a gym shelf with a BOGO 50% OFF tag, promotional badge reading ENDS JUN 10 — GNC's Ghost Birthday BOGO 50% is open to all customers — no PRO membership needed — through June 10. 5

GNC's Ghost Birthday BOGO 50% off (Ghost's 10th anniversary celebration) applies to the full Ghost line — Whey Protein, Amino, Legend pre-workout, Greens, Hydration, energy drinks — and is open to all customers, no PRO membership required, through June 10. 5 At $54.99 per Ghost Whey tub, two tubs via BOGO come out to $82.49 — $27.50 saved.

June 8 is a bigger expiry cluster at GNC. Three promotions end that day:

PRO Access BOGO 50% Mix-and-Match (11 brands: Optimum Nutrition, GHOST, Alani Nu, GNC AMP, Beyond Raw, GNC Pro Performance, Raw Nutrition, RYSE, Gorilla Mind, Axe & Sledge, Alpha Lion): PRO members only, expires June 8, 5 verifications last confirmed 18h ago. 5 6 This beats the everyone-gets-it BOGO 50% for PRO members with mixed carts — you can pair across brands.
Up to 50% off multivitamins and up to 45% off vitamins A–Z both expire June 8. 6
PUMPAF ($10 off when GNC Creatine and Beyond Raw LIT AF v2 pre-workout are both in the cart, expires June 8): not visible on the GNC homepage — likely email- or app-exclusive. 6 Both items must be present; the code won't apply to creatine alone.

One new deal since yesterday: BUM Energy BOGO Free (buy one, get one free) at select GNC locations in-store, also through June 10. 5 PRO Access members: limit 12 single units + 4 cases. Everyone else: limit 6 single units + 2 cases. Online equivalent not available.

Separately, the ongoing Free $44.99 Pro Performance Creatine on orders of $125+ promo runs through September 17 — 49 verifications. 6

Amazon deals — Six Star BOGO 80% breaks whey drought (budget tier)

Protein powder tub, electrolyte variety pack, and vitamin D3 bottle on a white surface with price tags showing $13.65, $10.32, and $4.99 — Three Amazon health deals from the current window, all requiring Subscribe & Save activation. AI-generated image

Six Star 100% Whey Protein Plus (1.8 lb, Kellogg's Froot Loops flavor) — Buy One Get One 80% off on Amazon: two tubs for $27.29 after a 5% Subscribe & Save discount and a $19.85 multibuy discount applied to a starting price of $49.62 for two. 7 That's roughly $13.65 per tub, or about $0.75 per 30g protein serving. Original list price is $29 per tub. Slickdeals Frontpage with +28 votes; 19 community comments, split. Requires both Subscribe & Save enrollment and the multibuy promotion to be active simultaneously — neither alone gives this price. Only the Froot Loops flavor qualifies; other flavors don't carry the multibuy promotion. No expiry announced; Amazon promos can end without notice.

Community reaction is divided. Slickdeals user stevoluks called the macros "actually pretty good — 170 calories for 30g of protein; BUT, there are a bunch of additives for sure." 7 User gboy13, who bought it, confirmed the $27 out-the-door price and noted the per-serving cost beats Target's Up & Up store brand ($0.83 per 25g serving). Slickdeals user TealScent2393 called the macros "horrible" and said it was only suitable for a dirty bulk. Per Slickdeals editor notes, this is $12.71 below the next-best comparable online price. 7

Six Star is a budget-tier brand — not on the same shelf as Optimum Nutrition, Dymatize, or Isopure in community perception. The whey drought at the standard and premium tier continues: the closest alternative, Optimum Nutrition Gold Standard Whey, is at ~$41.50 on Amazon (27% off), still below the discount depth needed to reach Slickdeals Frontpage.

The community thread has a running debate on why premium whey deals have dried up. User AdamE8805 referenced a report attributing it to social media driving whey demand sharply upward while cheese demand — and therefore whey production as a cheese byproduct — declined. 7 User wowmuchawesome raised GLP-1 drugs (semaglutide / tirzepatide prescriptions) as a possible driver: users with reduced appetite from those medications reportedly turn to high-protein, low-volume supplements to hit their protein targets.

Sports Research Hydrate Electrolytes Powder Packets (Variety Pack) — 16-pack for $10.32 or 32-pack for $14.56 on Amazon, down from a regular $36. 8 Requires three stacking actions: clip the on-page coupon, enroll in Subscribe & Save, and apply promo code DDVRGLBB. Slickdeals Frontpage with +35 votes. Select accounts only — some users report the coupon isn't available on their account. Sugar-free formula with six electrolytes, 65+ trace minerals, seven vitamins, and coconut water powder. Flavors: Raspberry Lemonade, Cherry Pomegranate, Lemon Lime, Passion Fruit. Sodium-to-potassium ratio: 400mg:200mg. No expiry announced.

Andrew Lessman Vitamin D3 5000 IU (150 capsules) — $4.99 on Amazon (regular $24.99, 80% off). 9 Manufactured by ProCaps Laboratories; 4.8-star Amazon rating from 2,262 reviews. The Slickdeals post is a forum thread with a score of +1 and zero community comments — no crowd-verified confirmation that the price is live and active. The posting account is new (registered June 2026, single deal post). Price may be live but community confidence is low; check the Amazon listing directly before buying.

MyProtein — 40% sitewide and $9.99 creatine unchanged

MyProtein US continues to run its 40% off almost everything sitewide auto-discount and Creatine Monohydrate Powder (1.1 lb) at $9.99 (auto 50% off from $19.99) — no changes from June 5. 10 The "Up to 50% off Creapure" banner (Creapure is a patented high-purity creatine monohydrate from AlzChem, Germany) also remains active, linking to Clear Whey Isolate. Other current homepage prices: Impact Whey Protein at $19.99, Impact Whey Isolate at $29.99, Clear Whey Isolate at $44.95. Free shipping threshold is $99 — raised from $79 on June 3.

Costco — May book final day tomorrow; June book starts June 15

The Costco May 2026 coupon book (May 11 – June 7) ends at close of business tomorrow. Two health items in the book apply automatically at the warehouse register: 11

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

No coupon or code needed — Costco membership required.

After the May book expires June 7, there is an 8-day gap (June 8–14) with no coupon book coverage. The June+July 2026 coupon book begins June 15 and runs through July 19 — this is Costco's standard schedule, not a delay. 11 The specific health deals in the June+July book haven't been announced yet; Costco Insider (a third-party Costco deal aggregator, not affiliated with Costco) notes the book typically leaks around June 13–14 for subscribers.

During the gap week, the current Costco Weekly Insider — which runs June 1–28 — includes PediaSure with OptiGRO Plus Kids Shake (vanilla, 24-count) at $29.99 after an $8 discount (regular $37.99, item #1268174, limit 10). 12 No adult protein powder, sports nutrition, or vitamins appear in the current Weekly Insider rotation.
