Health Deals Radar — June 3, 2026
Two iHerb codes labeled "Expires: today" — `618KMH26` (26%) and `MAY26BC` (15% brain health) — remain in active aggregator listings but face imminent checkout cutoff; `MAY26BC` carries a staleness caveat (last staff-verified 6 days ago). Three Vitacost brand codes (`20IRWIN`, `DRMERC`, `15NONGMO`) were pulled ahead of their listed expiry dates, while anchor code `ANNIE15` held. GNC adds a PRO Access BOGO 50% Mix-and-Match tier across 10 brands; the all-user GHOST Birthday BOGO 50% runs through June 10 on gnc.com. MyProtein's free-ship threshold rose from $80 to $99. Slickdeals surfaces four supplement deals — a 75%-off GLP-1 protein powder, Nature's Bounty Hair/Skin/Nails gummies at $6.83 for 2×80ct, and two magnesium deals with community quality warnings. Costco's June+July book public preview remains overdue.
Two iHerb codes that were supposed to expire today —
618KMH26 (26% off) and MAY26BC (15% off brain health) — are still sitting in DontPayFull's active listings as of this morning's scan. Both carry "Expires: today" labels, which means checkout may cut off at any point. GNC's Premier Protein BOGO Free also ends today (in-store only). On the Vitacost side, three brand codes that appeared last week — 20IRWIN, DRMERC, and 15NONGMO — were silently pulled from aggregators, while anchor code ANNIE15 held with no expiry date in sight. Costco's June+July book is still locked behind a subscriber wall; the public preview window based on May's release pattern was June 3–4, so check again tomorrow.Active codes at a glance

Expiry watch
iHerb
618KMH26 and MAY26BC — both labeled "Expires: today." 1 Both remain in the active codes section on DontPayFull as of this morning. 618KMH26 (26% off, 618 shopping festival early access) was last staff-verified on June 2 with four total verifications; MAY26BC (15% off brain health supplements) has 14 verifications but its last staff check was six days ago. That staleness on MAY26BC is a flag — the code may have already stopped working at checkout. If you have a cart with brain health items, test it now rather than waiting for tonight.GNC Premier Protein BOGO Free — last day, in-store only. 2 Buy one Premier Protein item, get one free at participating GNC stores through end of day June 3. PRO Access members are capped at 12 single units and 4 cases; all other customers are limited to 6 single units and 2 cases. There is no online equivalent for this offer.
iHerb
MAY26HH — expires June 4. 1 15% off heart health supplements. Six verifications; last confirmed active via DontPayFull. One day left.Costco May book — expires June 7. 3 Four days remain on the two remaining health items: Orgain Collagen Peptides + Probiotics at $23.99 (regular $29.99, saving $6.00) and Ensure Original Nutrition Shake at $28.99 (regular $37.49, saving $8.50). Both apply automatically at the warehouse register with a Costco membership.
iHerb — two expiring codes and no June monthly replacement yet
As of today's sweep, no JUNE-, JUN-, or SUMMER-pattern codes have appeared on any aggregator — DontPayFull, Brad's Deals, or otherwise. 14 The only new code on iHerb today is
OM183 — 10% off for GCC countries (Saudi Arabia, UAE, Kuwait, Bahrain, Qatar, Oman), expiring June 7. Not applicable for US shoppers. 1For US-based carts today, the priority sequence:
- 26% discount, acting before checkout closes →
618KMH26(expires today — test at checkout first) - Brain health supplements →
MAY26BC(expires today — staleness caveat applies) - Heart health, one day to go →
MAY26HH(15%, expires Jun 4) - Premium wellness items, longer window →
DRBEST26(20%, through Jul 5) - New account, first order →
NEW20(20%, through Jul 5) - $60+ cart, reliable fallback →
GOLD60(10%, 926 verifications, no expiry)
Vitacost — three codes gone, ANNIE15 holds
Three brand codes that were added last week have been removed from DontPayFull's Vitacost active listings between June 2 and June 3. 56 None appear in the expired/inactive section — the removals look like deactivations rather than standard expiry, particularly
15NONGMO, which was pulled two days before its listed June 5 end date.| Code removed | Was for | Listed expiry | Actual removal |
|---|---|---|---|
20IRWIN | Irwin Naturals (supplement brand) | Jun 14 | Between Jun 2–3 |
DRMERC | Dr. Mercola supplements | Jun 14 | Between Jun 2–3 |
15NONGMO | Select non-GMO products | Jun 5 | Between Jun 2–3 (2 days early) |
The codes
BIONUTRITION (20% off Bio Nutrition products) remains listed as active on DontPayFull — now Day 3 past its expected June 1 expiry, with only one total verification. 5 Whether it still works at checkout is unverifiable here; if your cart contains Bio Nutrition items, test it.What's solid for today:
- Irwin Naturals, Dr. Mercola, non-GMO items → those codes are gone; fall back to
ANNIE15(15%, 37 verifications, no expiry) - Jigsaw Health products →
WKND1(30%, through Jun 8) - Active Lifestyle & Fitness →

GNC — PRO members get a new BOGO tier; GHOST BOGO open to everyone through Jun 10
Two separate BOGO 50% promotions are running at GNC right now, with different eligibility. 2
GHOST Birthday BOGO 50% (all users, through Jun 10): GHOST (a sports nutrition brand celebrating its 10th anniversary) is running buy-one-get-one 50% off across its full product line — WHEY Protein ($54.99), Vegan Protein ($49.99), LEGEND V4 Pre-Workout ($44.99), BCAA ($29.99), Greens ($44.99), Hydration Sticks ($29.99), Energy Drinks 12-pack ($29.99). No membership required; available in stores and online. The promotion dropped off DontPayFull's active code listing on June 2 but remains live on gnc.com. 7 Go directly to gnc.com for the GHOST Birthday Sale page.
PRO Access BOGO 50% Mix-and-Match (PRO members, 10 brands): New as of today's scan — GNC PRO Access members can mix and match across 10 brands for a second-item BOGO 50%: Optimum Nutrition, Alani Nu, GNC AMP, Beyond Raw, GNC Pro Performance, Raw Nutrition, RYSE, Gorilla Mind, Axe & Sledge, and Alpha Lion. In stores and online; no end date published. 2
BOGO 50% math: the 50% discount applies to the lower-priced item in the pair. Two identical GHOST WHEY tubs at $54.99 each = $82.49 effective (25% off the $109.98 combined retail). For mixed carts, put the higher-priced item first.
MyProtein — free shipping threshold raised to $99
The 40% OFF ALMOST EVERYTHING sitewide auto-discount remains active, and Creatine Monohydrate Powder holds at $9.99 (regular $19.99, 50% off, no code needed). 8 One change: the free shipping threshold moved from $80 to $99. 8 The creatine itself at $9.99 falls below the free-ship floor; a second item (protein powder, electrolytes, etc.) at 40% off typically pushes past $99 without much difficulty.
Current weekly spotlight items at 40% off: Creatine Gummies, Electro X Hyrox Stick Pack, Essential Omega-3 Softgels, and 100% Citrulline Malate Powder. 8
Slickdeals picks — three buys and one to approach carefully
GLP-1 Support Nutrient Powder — $14.99, Deal Score +7. 9 The Vitamin Shoppe (US national supplement retail chain) has this 2.87 lb / 30-serving tub at $14.99, down from $59.99 (75% off). Available in Chocolate or Vanilla. Formulated for people on GLP-1 medications (Ozempic, Wegovy) with 25g protein per serving, but community commenter Tel06c notes it functions as a general protein supplement for muscle building as well. No coupon code needed — direct shelf price. Free shipping on orders $45+; four cans puts you there.
Nature's Bounty Hair, Skin & Nails Gummies — $6.83 for 2×80-count, Deal Score +5. 10 Amazon S&S + clip 30% coupon + multibuy discount stacked to $6.83 total ($3.42 per bottle), off the $15.76 standard two-pack price (57% off). 2,500 mcg Biotin, Strawberry flavor. This product previously hit Slickdeals Frontpage at $3.50 with a Deal Score of 29 — today's price is higher than that all-time benchmark, but still well below regular retail. Activating S&S at 10% (requires 5+ active subscriptions in the billing cycle) drops the total to $6.04; at 15% it goes to $5.66. Requires Prime, Subscribe & Save activation, and clipping the 30% coupon.
Vitamatic Magnesium Glycinate 2-Pack — $10.44, Deal Score +8. Read the community warning first. 11 Amazon S&S + clip 35% coupon brings two 180-count bottles to $10.44 (58% off the $24.99 typical price). The issue: Slickdeals commenter AsifAhmedVienna pointed out this product is not pure Magnesium Glycinate — it contains a Magnesium Oxide blend. Magnesium Oxide is poorly absorbed and is associated with GI discomfort in some users. Commenter DelightfulCrow1116 confirmed they had previously bought a fully glycinate version from this brand and flagged the blend change. If your goal is a clean glycinate supplement, this is not it. If price-per-tablet is the priority and absorption isn't a concern, $10.44 for 360 tablets is competitive. Bumping S&S to 15% (requires 5+ active subscriptions) drops the total to $9.49. The B6 content is worth noting: commenter tsa1 flagged it runs at twice the daily intake per tablet — consult a healthcare provider before high-dose B6 use.
iMATCHME Magnesium Glycinate — $6.17, Deal Score +15. No third-party testing confirmed. 12 120 capsules of 850mg Magnesium Glycinate with L-Theanine, Chamomile, and GABA via promo code
K9LOIJQH (50%) + 20% coupon clip + 10% S&S from $35.99 list. Community commenter NemoZo confirmed the brand does not appear in any of NSF, USP Verified, ConsumerLab, or BSCG databases — no third-party testing certifications found. Additionally, commenter www. notes that 850mg of magnesium glycinate delivers only ~155mg of elemental magnesium per serving (the usable mineral content), so hitting a 310–420mg daily elemental magnesium target requires two to three capsules per day, not one. At that dose rate, 120 capsules covers 40–60 days rather than the 120 implied by the count.BPN — still no June code on day 4
Best Price Nutrition (online supplement retailer) has had no active promotional banner since SPRINGFIT expired May 31. 1314 The standing code
BPNTEN takes 10% off your full order, with the standard exclusions: clearance items, already-discounted stacks, bars, and ready-to-drink (RTD) beverages. Cannot be combined with any other offer. Free shipping on orders $99+.Costco — June+July book still locked; May book has 4 days left
The June+July 2026 coupon book (valid June 15–July 19) has not been publicly released as of today. 3 Costco Insider (an independent Costco deal-tracking blog) shows the listing with a subscriber paywall. Based on the May book's release pattern — preview posted May 3, book effective May 11 — the June+July public preview was expected around June 3–4. Nothing has surfaced yet on Reddit's r/Costco or on EatingWell's deal coverage. Check back tomorrow.
In the meantime, two health items from the May coupon book expire June 7 — four days from today: 3
| Item | Sale price | Regular price | Savings |
|---|---|---|---|
| Orgain Collagen Peptides + Probiotics | $23.99 | $29.99 | $6.00 |
| Ensure Original Nutrition Shake | $28.99 | $37.49 | $8.50 |
Both apply automatically at the warehouse register; no additional step beyond a Costco membership.

What to watch June 4
Costco June+July book — public preview overdue based on May's timeline. First thing to check tomorrow morning. 3
iHerb
MAY26HH — expires June 4. Last chance on heart health 15%. 1iHerb June monthly code — three consecutive days of searching across all major aggregators have turned up nothing. If a standard June code exists, it hasn't surfaced publicly yet. 1
618KMH26 / MAY26BC status — if these codes moved to expired by tomorrow, the anomaly resolves cleanly. If either is still listed active on June 4, they're likely DontPayFull display errors at that point.
