Health Deals Radar — May 31, 2026

ApiHub came fully back online this morning after a 5-day outage, meaning all four major coupon aggregators (DontPayFull, RetailMeNot, Groupon, Brad's Deals) were reachable for the first time since Tuesday. This is today's freshest verification sweep in nearly a week — and it surfaced three new finds that weren't visible during the outage window.

The single most time-sensitive item: BPN's SPRINGFIT code expires tonight at approximately 11:30 PM CDT. After that, the next expiry cluster hits Monday night.

Tonight's expiry watch

Three deals close by Monday morning. Highest urgency first:

BPN SPRINGFIT — ~11:30 PM CDT tonight. Psycho Pharma, Insane Labz, Panda Supps, and Nutrex Research all get 20% off. 1 Confirmed active as of this morning's scan; no countdown clock on the page. If you're buying from any of those four brands, tonight is the last chance.

GNC BOGO 50% Off Supplements — Jun 1. The buy-one-get-one-50% deal covers Creatine, Multivitamins, and Healthy Aging categories. 2 Excludes "everyday value price" products and some brands; online only, one per customer. GNC (General Nutrition Centers, a nationwide sports nutrition and supplement retailer) is new to this tracker as of today — see the GNC section below.

Vitacost WKND1 — Jun 1. 30% off sitewide, four community verifications, last confirmed May 30. 3 Standard non-stackable terms. This is the deepest percentage discount currently available on Vitacost — 15 points above the ANNIE15 fallback.

New finds today

Three codes surfaced this morning that weren't visible during the outage:

Vitacost WKND1 (30% off, expires Jun 1) — four verifications, three users each saved $10. 3 Replaces ANNIE15 as the go-to code for any Vitacost order today and tomorrow.

iHerb DRBEST26 (20% off premium wellness supplements, expires Jul 5) — 12 verifications, patriciagalvan40 saved $131.70 on May 23. 4 Note: this code's scope is "premium wellness supplements," not sitewide. If your iHerb cart contains non-wellness items, GOLD60 (10% off $60+, 921 verifications) may actually yield more in total savings. Run both scenarios before checking out.

GNC BOGO 50% Off Supplements (expires Jun 1) — a new retailer entering the tracker. Covered in its own section below.

Myprotein's sitewide 40% discount also returned today after a 2-day absence (May 29–30), though the end date remains unpublished.

Vitacost

Vitacost (online health and wellness retailer, a Kroger subsidiary with over 40,000 SKUs) currently has a deeper-than-usual code stack with WKND1 as the lead option for today.

Code	Discount	Applies to	Expires	Verifications
`WKND1`	30% off	Sitewide	Jun 1	4 (May 30)
`ANNIE15`	15% off	Select orders	Jun 3	37 (May 30)
`TEXT10`	$10 off	Any order	Jun 30	85 (May 30)
`CYBERSMS20`	10–20% (disputed)	Sitewide	Jun 1	8 (May 14)
`SELECTORG20`	20% off	Organic food & beverage	No set expiry	7 (May 24)
`30OURBRANDS`	30% off	Vitacost store brands	No set expiry	8 (Jan 2026)

WKND1 is the strongest code today — 30% off sitewide, confirmed four times, expires tomorrow. 3 Non-stackable, standard terms.

CYBERSMS20 expires tomorrow as well. The title on DontPayFull reads "20% Off All Orders," but the code description reads "Save 10% on your Vitacost order" — the two savings figures reported by verified users ($7.09 and $10) don't resolve the ambiguity. 3 Last community verification was May 14 (two weeks ago). Try it first; if it applies at 20% it outperforms WKND1, but the lower verification count makes WKND1 the safer choice.

SELECTORG20 (20% off organic food and beverage items) is worth a mention if your cart is primarily organic food — it outperforms ANNIE15's 15% on eligible items, though the scope is narrower. 3

30OURBRANDS — 30% off Vitacost's own store-brand products. Eight verifications, but the most recent community confirmation was January 2026. Use with caution; test at checkout before finalizing a large order. 3

Vitacost also has three active no-code category promotions:

Sports Protein Powders from $13 — verified May 31, expires Jun 2 3
Vegan Products from $1.55 — verified May 31, expires Jun 7 3
Gluten-Free Food & Supplements from $1.55 — verified May 31, expires Jun 9 3

Specific participating products for these promotions aren't listed on the aggregator page — browse the corresponding Vitacost category pages to see what's included.

iHerb

iHerb (international online supplement retailer serving US customers) has nine confirmed codes today — the highest count in this tracking cycle. The full ranked stack:

Rank	Code	Discount	Condition	Verifications	Last confirmed
1	`GOLD60`	10% off	$60+ min, $50 max	921	May 31 (today)
2	`NEW20`	20% off	First order, new accounts only	730	May 31 (today)
3	`DONTPAYFULL`	10% / 5%	iHerb brand / other brands	210	May 31 (today)
4	`SIC1234`	10% off	Sitewide	195	May 31 (today)
5	`KBF3096`	Up to 40% off	Select items	179	May 31 (today)
6	`LEC9737`	15–20% (disputed)	Sitewide	241	May 31 (today)
7	`DRBEST26`	20% off	Premium wellness only	12	May 23
8	`MAY26BC`	15% off	Brain health supplements	14	May 26
9	`MAY26HH`	15% off	Heart health products	5	May 29

GOLD60 (10% off $60+) remains the safest, highest-volume code for general US shopping — 921 verifications, confirmed working today. 4 The $50 maximum savings cap kicks in on orders above $500, which is beyond most single-session carts.

DRBEST26 (20% off premium wellness) is the new code this week. With 12 verifications and a Jul 5 expiry, it has a longer runway than most May-themed codes. The "premium wellness supplements" scope isn't precisely defined on the aggregator listing — user patriciagalvan40 saved $131.70 on a May 23 order, suggesting a reasonably wide eligible product range. 4 For a budget-focused cart over $60, compare the absolute savings: 20% of eligible items with DRBEST26 vs. 10% of the full cart with GOLD60.

LEC9737 carries the same rate ambiguity as CYBERSMS20 on Vitacost — title claims 20%, description says up to 15%. 4 241 verifications and confirmed today means it's active, but the ceiling is uncertain.

MAY26BC and MAY26HH expire this week (Jun 3 and Jun 4 respectively) despite having "MAY26" in their names. Both are category-specific — brain health and heart health — so they're only useful if your cart already includes items in those ranges. 4

One previously tracked code, NKUNIMS, no longer appears anywhere on DontPayFull's iHerb listings (32 active codes scanned) or in site search results. It should be considered inactive. 4

No June-themed codes (JUN****, JUNE****) have appeared on any aggregator yet. Based on past cycles, they typically emerge around June 1–2.

Myprotein — 40% returns, prices confirmed

Myprotein US (UK-founded sports nutrition brand operating at us.myprotein.com) restored the "40% off almost everything" auto-discount today after removing it on May 29. 5 No code required — the discount applies automatically at checkout. End date is not shown anywhere on the site.

Current confirmed prices:

Product	Sale price	Regular price	Discount
Creatine Monohydrate Powder, 0.5 lb	$9.99	$19.99	50% off (auto)
Impact Whey Protein, 0.55 lb	$19.99	$36.35/lb implied	40% off (auto)
Impact Whey Isolate, 0.55 lb	$29.99	$54.53/lb implied	40% off (auto)

Creatine at $9.99 for 0.5 lb (50% off, automatic) is the standout price here. 5 6 The free shipping threshold listed in product metadata today is $70; previous data showed $80 — the discrepancy is unconfirmed and may reflect metadata lag rather than a policy change. 7

BPN — SPRINGFIT final call

Best Price Nutrition (online supplement retailer at bestpricenutrition.com, operating since 1999) has SPRINGFIT active on its final day — the code expires at approximately 11:30 PM CDT tonight. 8

"20% OFF Psycho Pharma, Insane Labz, Panda Supps and Nutrex Research. Use Code 'SPRINGFIT'" — BPN homepage banner 1

BPN's SPRINGFIT promotion covers Psycho Pharma, Insane Labz, Panda Supps, and Nutrex Research — 20% off with code SPRINGFIT, expires tonight. 1

The 20% applies sitewide within those four brands. Representative in-stock products include Insane Labz Psychotic (pre-workout), Nutrex Creatine Drive, Psycho Pharma Edge of Insanity, and Panda Supps Pandemic. Free shipping threshold is $99. There is no on-page countdown. 9

GNC — new to coverage

GNC (General Nutrition Centers, a nationwide US supplement retailer with locations and online sales at gnc.com) enters the tracker today with three concurrent promotions: 2

Deal	Discount	Expires	Notes
BOGO 50% off supplements	Buy 1, get 1 at 50% off	Jun 1 — tomorrow	Creatine, Multivitamins, Healthy Aging; online only, 1 per customer; excludes "everyday value" items
Up to 50% off multivitamins	50% off	Jun 8	Broad multivitamin sale; 1 verification
Up to 65% off clearance	65% off	Jun 8	Clearance items only

The BOGO deal is the most time-sensitive and the widest-scoping. If you're buying creatine or a multivitamin bundle, pairing two items under the BOGO structure means the second item costs half price. Confirm product eligibility at checkout — "everyday value price" items and some specific brands are excluded. 2

Costco + Amazon (via Slickdeals)

Costco May 2026 coupon book runs through June 7 — seven days remain. Two health items are confirmed: 10

Item	Sale price	Regular price	Savings
Orgain Collagen Peptides + Probiotics	$23.99	$29.99	$6 off
Ensure Original Nutrition Shake	$28.99	$37.49	$8.50 off

Orgain is a health food brand focused on organic protein and collagen products; Ensure is an Abbott clinical nutrition brand. Both prices apply automatically at the warehouse register with a Costco membership. Source is third-party Costco Insider blog (costcoinsider.com), which is unaffiliated with Costco Wholesale. 10

The June + July 2026 coupon book (June 15–July 19) has been confirmed as an upcoming release. Preview content is currently subscriber-only on Costco Insider. Public preview typically posts 2–3 days before the book starts — that puts it around June 12. 10

Amazon deals via Slickdeals — four supplement deals posted by the Slickdeals (deal-sharing community at slickdeals.net) community in the past 24 hours, all requiring Subscribe & Save (S&S) enrollment: 11

Product	Sale price	Regular price	Discount	Condition
Life Extension Zinc Caps 50mg, 90ct	$3.71	$6.75	~45% off	S&S + free shipping w/ Prime or $35+
Centrum Silver Multivitamin 50+, 80ct	$4.39	$7.99	~45% off	S&S + free shipping w/ Prime or $35+
Nature's Bounty Vitamin D3 Gummies, 2×90ct	$9.06	$29.58	~69% off	S&S + additional coupon clip
Emergen-C Vitamin C Powder 1000mg, 90ct	$18.54	$33.72	~45% off	S&S + additional coupon clip

Life Extension is a supplement brand focused on longevity and healthy aging; Centrum is a Haleon brand; Nature's Bounty is a Nestlé Health Science brand; Emergen-C is a Haleon vitamin C powder brand. The D3 gummies deal requires both the S&S enrollment and an on-page coupon clip — the ~69% total discount only applies when both are active at checkout. 11

Code-stacking guidance

Vitacost and iHerb codes are generally non-stackable — only one discount code per order. The decision logic for each cart type:

Vitacost orders today (May 31):

Any order → try WKND1 first (30%, expires tomorrow). If it fails, fall back to ANNIE15 (15%)
Order above $66.67 → compare WKND1 (30%) vs. TEXT10 ($10 flat); WKND1 wins above that threshold
Organic food/beverage only → test SELECTORG20 (20%) vs. WKND1 (30%); WKND1 is broader but SELECTORG20 may stack differently — verify at checkout
Vitacost store-brand cart → 30OURBRANDS may apply (30%), but last community verification was January; test before committing

iHerb orders today:

Returning customer, cart $60+ → GOLD60 (10%, 921 verifications, confirmed today)
New customer → NEW20 (20%, 730 verifications, confirmed today)
Premium wellness-focused cart → compare DRBEST26 (20% on eligible items) vs. GOLD60 (10% on full cart)
Category buyer: brain health → MAY26BC (15%, expires Jun 3); heart health → MAY26HH (15%, expires Jun 4)

GNC BOGO math: The second item costs 50% of the lower-priced item in the pair. If you're buying two identical tubs of creatine, the effective discount is 25% off the combined price — not 50%. Buy the more expensive item first; the cheaper one takes the 50% discount.

BPN SPRINGFIT tonight: Standard 20% off, no stacking noted. Free shipping at $99. If your cart clears $99, the free shipping further improves the effective discount.
