Health Deals Radar — May 22, 2026

MyProtein's Memorial Day sale is live — but it's "up to 50% off" everything, not a standalone 35% banner. Price-checking against CamelCamelCamel confirms only one Amazon deal is at a genuine all-time low today. Two urgency windows are running out: Vitacost SELECTBRON expires Sunday morning, and iHerb MAY26BC closes Tuesday. No new promo codes have surfaced in the past 24 hours.

⭐ = CamelCamelCamel-confirmed all-time low

All four US codes confirmed active as of this morning. 1 2 No new Memorial Day-specific code has appeared in the past 24 hours. 3

*22WELLNESS22 has been active for at least three weeks; no official expiry date has been published — verify at checkout.

For carts over $60: MAYWELLNESS and 22WELLNESS22 both deliver 22% off with two uses per account. Either works; MAYWELLNESS has a published May 30 deadline, giving you a clear window to plan a second order.

For carts under $60: MBDAILY (20% off, no minimum, one-time use) is the only US code with no spending floor.

For brain health supplements: MAY26BC is down to its last five days. It covers lion's mane, nootropics, omega-3 fish oil, bacopa, and similar brain health items at 15% off — but expires May 27 at 10:00 a.m. PT. User u/Horror_Shirt5260 on r/iHerbpromocode_ confirmed: "DQL3272 + MAY26BC for 15% off brain health supplements (ends 5/27/26 at 10:00 AM PT)." 2

Stacking: iHerb accepts one referral code plus one promo code per order. Enter the referral code first. Referral codes currently in circulation: DVO4205 (long-standing, recommended by r/iherbcodeshare user u/honeyjalapenos) 1 and DQL3272 (paired with MAY26BC). 2

SELECTBRON takes 20% off all Dr. Bronner's products at Vitacost (a Kroger-owned online natural products retailer) and expires Sunday, May 25 at 7:00 a.m. ET — roughly 65 hours from the time of this writing. 4

Dr. Bronner's (an organic personal care brand best known for its multi-use castile soaps, body lotions, and lip balms) stocks items that run $16–$20 at list price for a 32 oz bottle of castile soap. At 20% off, that drops to roughly $13–$16 per bottle. Note: direct page verification of SELECTBRON was blocked by anti-scraping; the code and expiry come from search engine snippets referencing the Vitacost coupon detail page. Verify it applies at checkout before relying on it.

No Vitacost Memorial Day sitewide code has surfaced. RetailMeNot lists a generic $10 off sitewide (valid through June 30) and a 15% off sitewide (through June 25) — neither is Memorial Day-specific. 4

CamelCamelCamel (a price-tracking tool for Amazon) data was available for five of the key deals this cycle, enabling genuine historical context. The picture is mixed.

Physician's Choice Fiber Gummies for GLP-1 Support (raspberry lemon, 60 count): $13.56 (32% off list price $19.97). 5 6

CamelCamelCamel confirms this is the all-time low since tracking began six months ago. Price history: high $16.97 (April 23), average $15.11, current $13.56. 6 Subscribe & Save stacks on top — select S&S at checkout to save up to 40% total, per Everyday Health. 5 Designed for people on GLP-1 medications (semaglutide/Ozempic, tirzepatide/Mounjaro), the formula uses chicory root fiber and pectin for digestive support.

Naturebell Pure Magnesium Glycinate (500 mg, 240 veggie capsules): Everyday Health lists this at $15.96 (41% off list price $26.95). 5 CamelCamelCamel, however, shows the current third-party new price at $19.95 as of May 22 — a $3.99 gap. 7 Amazon's own stock is listed as unavailable. The all-time low was $15.00 on Black Friday 2025 (November 26), so the $19.95 level is not at or near that floor.

Check the current price on the product page (ASIN B0C88BJYX2) directly — if it's near $15.96, the Everyday Health figure may reflect a brief in-stock Amazon window; if closer to $19.95, you're buying from a third-party seller at a higher price.

Garden of Life Grass Fed Collagen Peptides (unflavored, 28 servings): $32.89, confirmed by both Everyday Health and CamelCamelCamel. 5 8 Context from CCC: the all-time low was $17.25 in January 2020; the all-time high was $33.94 in November 2024; the average is $28.30. At $32.89, the current price is only $1.05 below the all-time high and $4.59 above the long-run average. Everyday Health describes it as "30% off," but CCC's tracked list price is $30.09 — the 30% calculation basis isn't transparent. The discount is real; the framing is not a historical bargain. It's a popular product (over 20,000 Amazon buyers in the past month per Everyday Health 5) at a price worth watching but not urgently grabbing.

YOSUDA Magnetic Rowing Machine (Model US-181, 16 resistance levels, Bluetooth): approximately $189.99–$199.99 via third-party sellers. 9 10 List price is $299.99. CamelCamelCamel's all-time low for third-party new was $179.97 on March 25, 2026 — the current price is roughly $10–$20 above that floor. Amazon's own inventory is out of stock; verify the third-party listing is still active before purchasing. Yahoo/Live Science covered this as a pre-Memorial Day fitness deal. 9

Lunakai Magnesium Glycinate (120 mg elemental magnesium + Vitamin B6 as P-5-P, 90 capsules): base price approximately $19.91 (CamelCamelCamel third-party new, May 16). 11 Stack a 25% clip coupon (clip on the product page before adding to cart) plus Subscribe & Save to reach a final price around $9.96 shipped, per Money Saving Mom. 12 CCC has tracked this ASIN for only six days — no meaningful all-time-low comparison is available yet. Cancel the S&S subscription after the first delivery if you prefer not to autoship.

NeoSilent Walking Pad with Incline Under Desk Treadmill (4-level, up to 9% grade, BLDC motor): Everyday Health lists it as 70% off; Yahoo Shopping reported 59% off at $150 (original $367). 5 CamelCamelCamel has no price history data for this ASIN (B0GZCQSV5N) — it may be a recently listed product. The 11-percentage-point gap between the two sources is unresolved; check the live Amazon price before purchasing.

Eu Natural Urinary Harmony (D-Mannose & Hibiscus Supplements, 60 capsules): Everyday Health lists it at $59.99 (20% off, Memorial Day May 25 only). 5 CamelCamelCamel shows the list price for ASIN B016CCG256 as $29.99, and the current third-party new price also at $29.99 (as of May 13). 13 This is a significant discrepancy — Everyday Health's $59.99 is double CCC's listed price. Amazon also carries a "60 Count (Pack of 2)" variant, which could account for the difference if the affiliate link resolved to the bundle. Verify the exact SKU and price on Amazon before acting on this one.

All six health-related deals in the Costco May 2026 Instant Savings Book are confirmed unchanged from last check. 14 15 Discounts apply automatically at the register — no coupon code needed. Costco is closed on Memorial Day (May 25); all deals remain valid through June 7.

The Once Upon a Farm Immunity Blends 12-pack is new to this coupon cycle.

Costco members who purchased any of these items within the past 30 days can request a price adjustment at the returns counter or via costco.com/PriceAdjustmentView. 16

Community find — Humm Kombucha 8-pack clearance, $4.97 (Midwest, YMMV): Spotted May 20 by Reddit user u/swifthandsam in a Midwest warehouse. 17 The $0.97 price ending is Costco's clearance marker. The post earned 161 upvotes and 52 comments; multiple Midwest members confirmed the deal at their stores, while at least one California commenter reported the product at full price. Some Midwest locations have already sold out. Check your warehouse tag before counting on it.

MyProtein (a UK-founded sports nutrition brand owned by The Hut Group, best known for Impact Whey Protein and creatine products) launched a sitewide sale today. The official homepage banner reads: "UP TO 50% OFF EVERYTHING + EXTRA 10% OFF ON THE APP USE CODE: APPOFFER." 18

Yesterday's entry previewed this as a "35% off Memorial Day sale," sourced from third-party coupon aggregators. That framing was incorrect — the actual promotion is "up to 50% off" with no Memorial Day label, and the app code APPOFFER stacks an additional 10% on top. 18

MyProtein allows only one discount code per order, but the app extra 10% applies automatically alongside the sitewide promotion. 19 The stacking relationship with referral codes, student discounts, or newsletter sign-up codes is not confirmed — treat single-code-only as the safe assumption. No end date for the current sale is listed on the homepage. Zero community deal-quality signals (upvoted threads, user confirmations, hot-deal badges) appeared on r/Supplements, r/Protein, or r/deals as of this morning's scan.

iHerb: Apply a referral code first, then a promo code. The referral credit lands as iHerb loyalty credits for a future order — it is not a direct cart discount. If your cart qualifies for both MAY26BC (brain health items) and MAYWELLNESS (order over $60), only one promo code can be applied; MAY26BC gives 15%, MAYWELLNESS gives 22% — use MAYWELLNESS if the whole cart is over $60, use MAY26BC only if the cart is exclusively brain health items and under $60.

Amazon Lunakai / Physician's Choice: For both deals, the sequence is: (1) click "Clip coupon" on the product page first, (2) then select Subscribe & Save at checkout. The coupon won't apply retroactively if you add to cart before clipping. Cancel the subscription in Amazon's "Manage Your Subscriptions" after the first delivery if you don't want recurring shipments.

Amazon S&S rates: The default Subscribe & Save discount is 5% (10–15% when you have five or more active subscriptions). Everyday Health's "up to 40%" total for Physician's Choice Fiber Gummies includes both the Memorial Day sale price and S&S — the baseline 32% sale price applies regardless of S&S.
