Health Deals Radar — May 27, 2026

The Memorial Day code wave has fully cleared. Nature's Way 20OFF75 and 30OFF125 expired at midnight CT, BPN HONOR20's banner is gone, and iHerb MAY26BC passed its 10 a.m. PT deadline this morning. What's left is a leaner but still actionable stack: MyProtein brought back the MDWSALE code alongside the auto-40% sitewide — the two appear to be running in parallel, with product-level rates that differ by SKU. Vitacost added four new category-targeted codes, two of which expire within days. iHerb's May 30 carry-forward codes (MBDAILY, MAYWELLNESS) should still be live per their published terms, though community verification is blocked this cycle.

This radar covers deals verified in the window from May 26 ~2 p.m. ET through May 27 ~2 p.m. ET.

Verification note: Reddit (r/iherbcodeshare, r/iHerbpromocode_) is fully blocked this cycle due to an ongoing API outage. iHerb codes listed above are unverified against community confirmations — they are included because their published expiry dates (May 30) have not passed and no contradicting evidence was found. Treat as "likely active, not community-confirmed." Verify at checkout.

MyProtein — MDWSALE code back alongside auto-40%

MyProtein (UK-based sports nutrition brand, US site at us.myprotein.com) is running two simultaneous promotions right now, which creates a slightly confusing checkout picture. 4 5

The sitewide auto-40% banner remains in place — no code needed. At the same time, product pages for individual SKUs display a Memorial Day Weekend Sale badge pointing to code MDWSALE, with rates that vary by product:

Product	Auto-40% display price	MDWSALE badge rate	Verify at checkout
Creatine Monohydrate (0.5 lb / 45 srv)	$9.99 (orig. $19.99)	40% off	Whether MDWSALE is additive or redundant
Impact Whey Protein (0.55 lb / ~10 srv)	$19.99 (orig. ~$33)	20% off	Whether MDWSALE reduces or replaces the auto-40%
Clear Whey Isolate (1.1 lb / 20 srv)	$44.95	20% off	As above

The honest answer is that no checkout test was run this cycle — the MDWSALE rate is lower than the auto-40% banner on whey and isolate SKUs, so it may be a code that applies on top of an already-discounted base price, or it may be a remnant from the weekend that now trails the auto-40% in practice. If you're ordering Impact Whey or Clear Whey, the auto-40% route (no code) is the safe default. For creatine, both paths show 40% and the end price should be $9.99 per 0.55 lb regardless. 5 6

Neither promotion has a published expiry date. Free shipping kicks in at $80 (US contiguous); orders below that pay $7.99.

iHerb — May 30 codes should be live, but can't confirm

MAY26BC expired at 10 a.m. PT today as scheduled. 7 The four codes that carried forward from earlier in the week all have May 30 or unpublished expiry dates and should still be active per their published terms — but Reddit's deal-sharing subreddits (r/iherbcodeshare, r/iHerbpromocode_) are fully blocked, so no community checkout confirmation is available this cycle.

Code	Discount	Min. order	Restrictions	Expires
`MBDAILY`	20% off	None	1× per account (USA)	May 30
`MAYWELLNESS`	22% off	$60	2× per account (USA)	May 30
`22WELLNESS22`	22% off	$60	2× per account (USA)	Not published
`MAY26SW`	15% off $60+ or 20% off $100+	$60	Worldwide	Not published

Best-value logic: For orders over $60, MAYWELLNESS (22%) beats MBDAILY (20%). For carts under $60, MBDAILY is the only option. MAY26SW is a global code without a USA restriction — useful as a fallback if the USA-only codes have been exhausted on your account.

Code stacking: iHerb allows one referral code plus one promo code per order. The previously community-verified stacks (KOD6351 + MAYWELLNESS, DQL3272 + MAY26BC) should still work for the carry-forward codes — enter the referral code first. With Reddit blocked, no new stacking confirmations are available today.

Vitacost — four new codes add category-specific depth

SELECTBRON (20% off Dr. Bronner's) expired May 26. Don'tPayFull cross-references with Groupon both confirm it's in the expired bucket. 1 8 The two baseline codes — ANNIE15 and TEXT10 — are still the most reliable picks, both verified by independent community members on May 26. 9

Four codes not previously tracked in this series surfaced from Don'tPayFull this cycle: 1

Short-dated codes (act before May 30):

VE601M — 20% off select capsule products, max 6 items per order, expires May 30. Staff-verified 3 days ago. Best for stacking with a capsule-heavy cart (multivitamins, softgels, encapsulated probiotics).
MAY26BC — 15% off select orders (confirmed to include California Gold Nutrition Omega-3 and Tru Niagen), expires May 29. Staff-verified 4 days ago.

Ongoing codes (no confirmed expiry):

CYBERSMS20 — 20% off all orders. Community-verified by 7 shoppers in the past 30 days; last confirmed ~May 14. This is a sitewide 20% code — stronger than ANNIE15's 15% — but the most recent confirmation is two weeks old. Worth trying at checkout; if it applies, it's the best sitewide rate currently available.
SELECTORG20 — 20% off select organic food and beverages only. Verified by 2 shoppers; last confirmed ~May 18. Cannot be combined with other discounts.

Stacking logic for today's Vitacost visit:

If your cart is capsule-heavy: try VE601M (20%, expires May 30) before it disappears.
If CYBERSMS20 works at checkout: 20% sitewide beats ANNIE15's 15%.
CYBERSMS20 fails? Fall back to ANNIE15 (15%, confirmed through Jun 2).
Add TEXT10 ($10 flat) only if your cart total is above $66.67 — that's where the $10 flat exceeds the 15% saving.

Note: Dr. Bronner's is flagged as an excluded brand on Offers.com for sitewide Vitacost discounts — keep that in mind when CYBERSMS20 or ANNIE15 terms aren't explicitly listed. 10

Amazon and Vitamin Shoppe — still no active codes

Amazon: For the seventh consecutive cycle, no health product deals (supplements, protein, vitamins, or fitness equipment) appeared across monitored aggregators. Slickdeals' health category page returns a 404; the Hot Deals forum's first page of 25 threads had zero health or supplement items. 14 CamelCamelCamel price-history context for Amazon health items is not available this cycle due to no active ASIN leads.

Vitamin Shoppe (a specialty health and nutrition retail chain): HONORS26 (15–20% off) expired May 25. No replacement code has appeared in four consecutive runs. The official coupons page shows no active promo codes — only standard free-shipping policy ($45+ orders). 15 This appears to be a normal post-holiday code gap; check back later this week.

Stacking guide — priority order for today

Today's field is thinner than the Memorial Day peak, but three complementary stacks cover most supplement shopping needs:

MyProtein (no code needed): Auto-40% off is the simplest high-discount option right now. Add MDWSALE at checkout to see if it stacks — if the displayed price stays the same, the auto-rate already applied; if it drops further, it stacked. No minimum order. 4
Vitacost capsule cart (before May 30): Try VE601M first (20% off capsule products, max 6 items). If your cart has non-capsule items too, split the order — capsule-eligible items under VE601M, then run a second cart under CYBERSMS20 or ANNIE15.
Vitacost general cart: Try CYBERSMS20 first (20% sitewide, last confirmed ~May 14). If it declines, apply ANNIE15 (15%, confirmed May 26). For carts above $66.67, add TEXT10 ($10 flat) and compare the two to pick the better total. 1 9
iHerb general cart ($60+): Apply referral code KOD6351, then promo code MAYWELLNESS (22% off $60+, through May 30). These are unverified this cycle but should be live per terms. If MAYWELLNESS fails at checkout, try 22WELLNESS22 (same rate, no USA restriction). Carts under $60: use MBDAILY (20%, no minimum, 1× per account).
iHerb under-$60 cart or non-USA: MAY26SW (15% off $60+, 20% off $100+, worldwide). The worldwide restriction makes it useful for non-US accounts or accounts that have used up the USA-only codes.

Code sources: Vitacost codes from Don'tPayFull community and staff verification; iHerb codes from prior Reddit community posts (r/iHerbpromocode_, r/iherbcodeshare) — Reddit verification not available this cycle. MyProtein prices from us.myprotein.com product pages. Costco deals from Costco Insider.
