Health Deals Radar — May 28, 2026

MAY26BC expires today (May 29 deadline), and VE601M — 20% off capsule products — follows it tomorrow (May 30), so both short-dated Vitacost codes are in their final hours. The two anchor codes ANNIE15 and TEXT10 held firm with 4-aggregator and 3-aggregator cross-verification respectively. MyProtein's auto-40% rolls into day 3 with no end date in sight, and the Costco May coupon book keeps running through June 7. iHerb codes remain unverifiable — Reddit is still blocked — and none of the four tracked codes have appeared on any aggregator this cycle.

Expiring tonight: Vitacost MAY26BC (May 29 deadline — final day today). 1

iHerb verification note: Reddit (r/iherbcodeshare, r/iHerbpromocode_) remains fully blocked. All four iHerb codes above are absent from every aggregator checked today (RetailMeNot, Brad's Deals, Groupon, DontPayFull). 2 3 Their published expiry dates haven't passed, so they may still work at checkout — but treat them as unconfirmed until Reddit access is restored.

Vitacost — two codes in final hours

Today is the last day for MAY26BC (expires May 29) and tomorrow is the deadline for VE601M (expires May 30). Both carry limited verification this cycle. 1

MAY26BC (expires May 29 — today): 15% off select orders. Only 1 verification on DontPayFull as of today's scan; no cross-aggregator corroboration. Works best on select SKUs — California Gold Nutrition Omega-3 and Tru Niagen were confirmed eligible in prior community reports. Low confidence but worth a checkout attempt if those items are in your cart.

VE601M (expires May 30): 20% off select capsule products, capped at 6 items per order. A DontPayFull (coupon aggregator with staff and community verification) staff member verified it on May 24; two community confirmations total. No other aggregator shows a matching capsule-specific code. The narrow product scope (capsule-format only — think multivitamins, softgels, encapsulated probiotics) and the 6-item cap mean it's most useful for a focused capsule restock rather than a mixed cart.

ANNIE15: 15% off sitewide, expires June 3. Cross-verified on all four accessible aggregators — DontPayFull (16 confirmations in the rolling 30-day window, last confirmed 8 hours ago), RetailMeNot (14 validations this week), Offers.com (Editor's Choice on May 28), and Groupon (active listing). 4 5 This is the most reliable code in today's Vitacost stack.

TEXT10: $10 off any order, expires June 30. DontPayFull shows 14 confirmations in the last 30 days, last confirmed 8 hours ago. RetailMeNot and Offers.com both list it as active. Groupon places it in the expired section — a discrepancy no other aggregator corroborates, so the code is treated as active but worth verifying at checkout. 1 The math: $10 flat beats 15% only on orders above $66.67.

CYBERSMS20: 20% off all orders, no confirmed expiry. Last community confirmation was around May 14 — two weeks ago — with no new validations since. 1 If it works at checkout it outperforms ANNIE15, but there's no recent signal it's still live. Try it first; if it declines, fall back to ANNIE15.

SELECTORG20: 20% off select organic food and beverages, no confirmed expiry. Limited to organic-category items and cannot be combined with other discounts. Two community verifications, last confirmed around May 18. 1

Stacking priority for today:

Select-SKU cart today → try MAY26BC (15%, expires tonight).
Capsule-heavy cart before May 30 → try VE601M (20%, expires tomorrow).
General sitewide cart → try CYBERSMS20 first (20%, stale but potentially live). If it fails, apply ANNIE15 (15%, confirmed).
Cart over $66.67 → compare ANNIE15 15% vs. TEXT10 $10 flat, take whichever produces the lower total.
Organic-only items → SELECTORG20 (20%), but confirm it can't be stacked before skipping ANNIE15.

iHerb — May 30 codes not found on any aggregator

With 48 hours until the MBDAILY and MAYWELLNESS expiry, none of the four tracked codes have appeared on RetailMeNot, Brad's Deals, Groupon, or DontPayFull. iHerb's own homepage was blocked by Cloudflare; the /specials page loaded but shows only product-level discounts, with no promo code entry area. 2 3

What RetailMeNot does show for iHerb today are generic aggregator-listed codes: 20% off for new customers (first order, valid through Jan 2027), 10% off orders of $60 or more (multiple-source verified), and a Buy 1 Get 1 at 80% off offer running through June 4. 2 These are aggregator claims, not community-confirmed in-cart verifications.

For the four community codes (MBDAILY, MAYWELLNESS, 22WELLNESS22, MAY26SW): their published terms haven't expired, and no aggregator shows them in an "expired" bucket. If you plan to place an iHerb order before May 30, it's worth attempting MAYWELLNESS (22% off $60+) or MBDAILY (20%, no minimum) at checkout — with the understanding that this cycle has no community verification to back them up.

MyProtein — auto-40% unchanged, day 3

MyProtein (UK-based sports nutrition brand, US site us.myprotein.com) is on day 3 of the same auto-applied 40% sitewide promotion. No code required; the discount appears at checkout automatically. No expiry date has been posted. 6

MyProtein "40% off almost everything" homepage banner — MyProtein's current primary homepage banner — the 40% discount auto-applies at checkout, no code entry needed. 6

Current sale prices with the auto-40% reflected: 6

Product	Sale price	Original price	Savings
Creatine Monohydrate Powder (0.5 lb / 45 srv)	$9.99	$19.99	$10.00 (50%)
Impact Whey Protein (0.55 lb / ~10 srv)	$19.99	~$33	~$13
Impact Whey Isolate (0.55 lb)	$29.99	~$50	~$20
Clear Whey Isolate (1.1 lb / 20 srv)	$44.95	—	Auto-40% applied

The MDWSALE promo code resurfaced on May 27 at variable rates (20–40% depending on SKU) but hasn't appeared on the homepage today and isn't listed on Groupon's MyProtein page as an active code. 7 With the auto-40% already in place, there's no checkout test confirming MDWSALE stacks on top of it. The auto-40% route is the verified path — use MDWSALE experimentally only if you want to test whether it produces a further reduction.

Free shipping applies on US contiguous orders over $80.

Costco — May book through June 7, June preview still pending

The June+July 2026 coupon book (June 15–July 19) has been confirmed but content has not been published. Based on Costco Insider's historical pattern, a preview typically appears June 1–3. 9

What's quiet today

Amazon: For the eighth consecutive daily cycle, no health product deals (supplements, vitamins, protein, or fitness equipment) appeared in monitored aggregator feeds. Slickdeals' Hot Deals forum and Popular Deals page had zero health category entries in the 24-hour window. 10 The structural gap persists: Amazon health deals don't surface through the Slickdeals deal-sharing format.

Vitamin Shoppe (specialty health and nutrition retail chain): Now in its fifth consecutive scan with no active public promo code since HONORS26 (15–20% off) expired May 25. Brad's Deals (deal aggregator) shows "no Vitamin Shoppe deals at this time." The post-holiday code gap continues. 11

Nature's Way: The expired Memorial Day codes 20OFF75 and 30OFF125 — both clearly expired per their stated terms of midnight CT May 26 — are still displayed on the legal promotions page as of today, now two days post-expiry. No replacement codes have appeared. The only current offers are permanent: Subscribe & Save 15%, Overstock up to 25%, Last Chance 40–60%, and email sign-up 20%. 12
