Thanks for your inquiry! **Q: What will be the expiry date (newest stock), If I order by early November ?** A: Greetings from Daiwa! Daiwa Peak Immune 4 Natural Immune System Booster currently in stock expires Dec 29, 2023. Thanks for your inquiry! **Q: Hi, Is this the same as AHCC, Noxylane4, BRM4. I used MGN3 which was pulled then Noxylane4 but they raised the price. Thanks so much....Steve** A: Hello and Greetings from Daiwa Health Development! AHCC is different from PeakImmune4, BRM4 and Noxylane4.  It is a blend of three mushrooms. The active ingredient in PeakImmune4, BRM4 and Noxylane4 is Rice Bran Arabinoylan Compound (RBAC).  RBAC is derived from an extract from rice bran that is broken down into a smaller molecule in a fermentation process using a very small amount of an enzyme complex from Shitake mushroom.    Although AHCC and PeakImmune4 work similarly on the immune system, primarily through white blood cells, PeakImmune4 has a much greater impact.  The two key areas that PeakImmune4 has increases macrophage activity to a much greater extent and is effective at lower dosage levels than AHCC.  Research studies show that AHCC does not have an effect in humans on NK cells (an important white blood cell) below 2g/day, while PeakImmune4 starts to increase NK cell activity at 500mg. This translates to a lower cost per daily dose for PeakImmune4.    PeakImmune4 and BRM4 are the same, both are made by Daiwa Health Development. They are supported by dozens of research and case studies.  While Noxylane4 does contain RBAC, it also contains another ingredient, Heated Algae Ingredient (HAI).  It is not known if HAI compromises the efficacy of RBAC.  All the research studies were done with only RBAC without HAI. Thanks for the great question! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Price *by S***Y on October 6, 2025* Been using this for years. Great Immune support supplement! ### ⭐⭐⭐⭐⭐ Excellent product and quick delivery. *by A***R on July 18, 2025* Excellent product and quick delivery. ### ⭐⭐⭐⭐⭐ Was skeptical but.... *by M***R on March 9, 2020* I bought this because of the reviews and because the health scare at the moment is crazy. I started to feel my throat swelling up and slight cough here and there so I took a chance that this will somehow help me out. I have been taking these for the past 5 days and I must say, they are holding me up pretty well. My cough has gone away but I have slight tightness at the throat which I can tolerate. This stuff slowly but surely has boosted up my immune system and I am very grateful for that. The amount you need to take daily is quite much...I just ended up taking 2 in the morning and 2 at the night which worked out fine. ## Frequently Bought Together - Daiwa PeakImmune4® – Immune Support Supplement for Adults with Rice Bran Arabinoxylan Compound (RBAC) and Enzyme from Shiitake Mushroom – 50 Capsules - Daiwa Krill Oil 1000mg Softgels - EPA DHA Krill Oil Omega 3 6 9 with Astaxanthin for Joint, Brain and Heart Health - Antarctic Krill Oil Supplement - 60/ct - Daiwa Plasmanex 1 - Blood and Vein Circulation Supplements – Balance Circulation, Encourage Healthy Legs and Veins - 60 Vegan Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/6201660-daiwa-peak-immune-4-immune-system-booster-rice-bran-shitake](https://www.desertcart.co.th/products/6201660-daiwa-peak-immune-4-immune-system-booster-rice-bran-shitake) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-28*
