Health Deals Radar — June 2, 2026

Two codes expire tomorrow (June 3) — iHerb 618KMH26 (26% off, 618 early-bird) and iHerb MAY26BC (15% off brain health) both go dark at end of day. GNC's GHOST Birthday BOGO 50% has dropped off coupon aggregators but remains live on gnc.com through June 10. MyProtein's 40% sitewide and the $9.99 creatine are both confirmed active. Vitacost picked up three brand-specific codes since June 1. Slickdeals bounced back with ~37 deals after yesterday's near-zero output.

The banner headline: iHerb added a 26% code today tied to the 618 shopping festival — and it's gone tomorrow.

Expiry watch

iHerb 618KMH26 — expires June 3. Today's new entry: 26% off for the 618 shopping festival (a mid-year e-commerce event with roots in Asian markets), covering supplements, beauty, sports products, and daily essentials. 1 DontPayFull added this code roughly 12 hours ago with a DPF staff verification, and a follow-up staff re-verification came 4 hours later. Geographic restrictions apply (select countries) — US shoppers have successfully used iHerb's 618 codes in past years, but the listing notes restrictions so verify at checkout. This is the single largest discount code on iHerb today; if you have a cart ready, tomorrow is the deadline.

iHerb MAY26BC — expires June 3. 15% off brain health supplements. 1 Fourteen community verifications, with a user saving $33.57 on the last confirmed use (May 26). This one was flagged for June 3 expiry in yesterday's issue; that deadline holds.

GNC Premier Protein BOGO Free — expires June 3, in-store only. Buy one Premier Protein item, get one free at participating GNC stores. 2 PRO ACCESS members can buy up to 12 single bottles and 4 boxes; all other customers are capped at 6 single bottles and 2 boxes. Online equivalent does not exist for this one.

Costco May book — expires June 7. Five days left on the May 2026 coupon book. Two health items remain active: 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). 3 Both discounts apply automatically at the register with a Costco membership.

iHerb — 618 code is today's lead

iHerb's 618 early-access code 618KMH26 represents a departure from the MAY-pattern codes that have dominated coverage for the past two weeks. 1 The 618 shopping festival, named after June 18, is a major Asian e-commerce event — iHerb runs targeted promotions for it annually. Four total verifications on DontPayFull, with the most recent community confirmation dating to May 26 (user queenmouse512) and two DPF staff verifications today.

iMATCHME Magnesium Glycinate 120-count capsule bottle, product image from Slickdeals — A separate Amazon supplement deal via Slickdeals: iMATCHME Magnesium Glycinate 850mg capsules with L-Theanine and Chamomile, 120-count. 4

The code KRB7Q2 (30% off, through June 30) was also added to DontPayFull today but is restricted to China mainland, Hong Kong, Taiwan, and Singapore — not applicable for US shoppers. 1 The code PJZ7818 (circulating on Reddit) has not appeared on any aggregator — DontPayFull, Groupon, Brad's Deals, or Offers.com — and is excluded from this issue's recommended codes.

iHerb code decision flow for June 2:

Cart with 618-eligible items, acting today → 618KMH26 (26%, expires tomorrow)
Brain health supplements, acting today → MAY26BC (15%, expires tomorrow)
Returning customer, $60+ cart → GOLD60 (10%, 921 verifications, no expiry)
New account, first order → NEW20 (20%, through Jul 5)
Premium wellness items → DRBEST26 (20%, through Jul 5, 12 verifications)

Vitacost — three brand codes added since June 1

Vitacost (Kroger-owned online health and wellness retailer) accumulated three additional brand-specific codes since yesterday's issue. 5 All three were community-verified within one day of posting:

Code	Discount	Brand scope	Expires
`20IRWIN`	20% off	Irwin Naturals (supplement brand)	Jun 14
`DRMERC`	10% off	Dr. Mercola Supplements	Jun 14
`15NONGMO`	15% off	Select Non-GMO Favorites	Jun 14

These join the codes already tracked from June 1: 20SELECTLIFE (20%, Active Lifestyle & Fitness, through Jun 8), MAY26HH (15%, Heart Health, through Jun 8), ORIGINS15 (15%, Healthy Origins, through Jun 15), and 15THEDAILY (15%, The Daily Crave, through Jun 29). 5

The code BIONUTRITION (20% off Bio Nutrition products) was expected to expire June 1 but remains listed as active on DontPayFull as of today — one verification, added June 1. 5 Whether this is a display lag or the code genuinely remains active is unconfirmed; test at checkout if your cart has Bio Nutrition items.

Vitacost code decision flow:

Irwin Naturals items → 20IRWIN (20%, through Jun 14)
Active Lifestyle & Fitness products → 20SELECTLIFE (20%, through Jun 8)
Heart health (CoQ10, Omega-3) → MAY26HH (15%, through Jun 8)

Slickdeals picks — four community-vetted finds

Slickdeals' supplement section recovered to roughly 37 active deals on June 2 after near-zero output on June 1. 10 Four deals cleared the quality bar:

Nature's Bounty Hair, Skin & Nails Gummies — $6.83 for 2×80-count. 11 Amazon S&S + multibuy + 30% clip coupon combined to $6.83 ($3.42 per bottle), 57% off the $15.76 standard two-pack price. Deal Score +5 — Slickdeals' staff-posted and community-confirmed threshold. Nature's Bounty (mass-market supplement brand) rates 4.6 stars across 69,635 Amazon reviews, 7,000+ monthly sold. Historical low: $3.50. Activating S&S at 10% drops this further to $6.04. Requires Prime (or $35+ for free shipping), Subscribe & Save activation, and clipping the 30% coupon.

Nature's Bounty Hair Skin & Nails Gummies 2500mcg Biotin 80-count bottle pair — Nature's Bounty Hair, Skin & Nails gummies 2-pack at $6.83 via Amazon S&S stack. 11

Atkins Strong Protein Shakes, 12-pack — $13.52. 12 Amazon S&S + 20% clip coupon after a $25.74 typical price, 46% off. Chocolate and Chocolate Peanut Butter flavors available. S&S at 15% (requires 5+ subscriptions in the month) lowers this to $11.72. This product previously hit Slickdeals' Frontpage at $15 with a Deal Score of 76 and 26 community comments — the current price is 30% below that benchmark. Requires Prime, S&S, and the 20% coupon clip.

GLP-1 Support Nutrient Powder — $14.99. 13 The Vitamin Shoppe (nationwide US health supplement retailer) has this 2.87 lb / 30-serving protein powder marked down from $59.99, 75% off. Chocolate or Vanilla. Per community comments, this is a protein powder formulated for people on GLP-1 medications (Ozempic, Wegovy), with 25g protein per serving and additional support ingredients — "It's protein powder with additional ingredients for people on Ozempic/Wegovy," according to Slickdeals user JenovaImproved. Hot Deals badge, Deal Score +2. Ships free on orders over $45 (four cans qualifies); in-store pickup also available.

iMATCHME Magnesium Glycinate, 120-count — $6.17. 4 850mg capsules with L-Theanine, Chamomile, and GABA, at $35.99 list price — 50% promo code K9LOIJQH + 20% clip coupon + 10% S&S stacked to $6.17 (82% off). Important caveat from community: Slickdeals user www. notes that "850mg of magnesium glycinate is actually only 155mg of [elemental] magnesium. So you would need to take 3 servings to get [the] daily recommended amount of magnesium." If your goal is hitting daily elemental magnesium intake, you're effectively looking at a 40-day supply rather than 120 days. Requires Prime, S&S, promo code K9LOIJQH, and a 20% coupon clip — each is a one-time or per-account use.

Costco — May book closing Jun 7, June+July book not yet public

Two health deals remain in Costco's May 2026 coupon book, both expiring June 7: 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

Orgain (organic protein and collagen food brand) and Ensure (Abbott clinical nutrition brand) prices apply automatically at the warehouse register — no additional step required beyond a Costco membership.

The June + July 2026 coupon book (scheduled June 15–July 19) remains a subscriber-only preview on Costco Insider as of this morning's scan. 14 Costco Insider is an independent blog unaffiliated with Costco Wholesale. Based on the May book's publish pattern (book started May 11, preview appeared May 3), a public preview of the June book is expected around June 3–4. Nothing has posted yet.

Context: why protein powder deals are thin

Slickdeals returned to normal volume today, but there's a structural reason traditional protein powder deals have been sparse: a global whey protein shortage reported by the Los Angeles Times on June 1 has some suppliers already sold out of their 2026 allotment. 15 Bulk whey concentrate prices are up an average of more than 40% in recent months; grass-fed whey isolate has risen more than 300% since 2023. Whey is a byproduct of cheese production and can't be independently scaled. The LA Times piece projects 12–18 months before retail prices reflect the full supply crunch. Today's protein section on Slickdeals featured Atkins' pre-mixed shakes and a GLP-1 support powder — no traditional whey or casein powder deals surfaced.

BPN — no June code

Best Price Nutrition's (online supplement retailer operating for 25+ years) SPRINGFIT banner has been removed from the bestpricenutrition.com homepage as of today. 16 The code covered 20% off Psycho Pharma, Insane Labz, Panda Supps, and Nutrex Research. No replacement June code has appeared on the site or via Google search. 16

Code-stacking guidance

iHerb — one code per order. Run the priority sequence:

618KMH26 (26%) today only, expires Jun 3 — use if your cart is eligible
MAY26BC (15%) for brain health items, expires Jun 3
DRBEST26 (20%) for premium wellness, through Jul 5
GOLD60 (10%, $60+ cart) as the reliable fallback — 921 verifications

Vitacost — one code per order. Match brand first:

Irwin Naturals → 20IRWIN (20%)
Active Lifestyle & Fitness → 20SELECTLIFE (20%)
Heart health → MAY26HH (15%)
No brand match → ANNIE15 (15%, 37 verifications)

GNC Ghost BOGO math: BOGO 50% applies 50% off the lower-priced item. Two GHOST Whey tubs ($54.99 each) = $82.49 total, effective 25% off. For mixed carts, put the higher-priced item first.
