SHII AHCC Clinical Strength,10 Days Supply – Vegan, Gluten-Free Immune Support Supplement with Extra AHCC Boost, Made from Functional Shiitake Mushrooms for Immune Balance Support and Overall Wellness
Top Reviews from the United States
I’ve been taking SHII Advanced Daily Immune Support Supplement for the past three days, and I’m already loving the formulation. This supplement delivers a strong and well-balanced blend for immune support. Unlike many other mushroom-based supplements, SHII provides a clinically studied dose of AHCC, which sets it apart from generic mushroom blends on the market.
One thing I really appreciate is that there’s no aftertaste or burping—something I’ve experienced with other immune-boosting supplements. The capsules ARE VEGAN, and the packaging is MY FAVORITE! The deep purple color is my fave, and it gives the product a premium feel that makes me excited to take it daily.
While I’ve just started my journey with SHII, I’m passing the rest to my mom, who recently faced serious kidney issues. Her immune system needs all the support it can get, and I trust this formula’s clean, vegan, gluten-free, and sugar-free ingredients to make a real difference.
If you’re looking for a high-quality immune support supplement without any unpleasant side effects, SHII is definitely worth trying. I’ll update on my mom’s experience soon!

5.0 out of 5 stars Great boost for Winter Immunity!
Verified PurchaseFull disclosure, I received this from a giveaway on Instagram. It was perfect timing as we headed into the depths of the darker, colder winter months - paired with travel and holiday stress. Now that I've made it through a full month of using this supplement, I can say that it's felt like a great immune boost! Travel during the holiday season is always some level of insane, and at this point nearing the end of January, I've been in top notch health. Also - love love love that there's the combination of vitamin D3 and magnesium (as a gloomy PNW person)! Not everyone knows you create a magnesium deficiency taking vitamin D, so I'm happy to have them combined. Great supplement! :)

4.0 out of 5 stars Good Quality
Style: Clinical Strength - 10 Days SupplyVerified PurchaseI really liked the high quality ingredients in these capsules. They were easy to take and had no aftertaste. I did notice an improvement in my overall energy as a dad of 2 under 2 and my immune system seemed better. However my only downside was the cost, It seems expensive for a 10 day supply only. But for the quality and effectiveness I might just do it!

5.0 out of 5 stars Small but Might
Style: Clinical Strength - 10 Days SupplyVerified PurchaseI’ve read reviews that say this is a small packet for the price but when you realize you’re getting capsules and not powder, it is actually good value for money! I put my capsules in this regular sized supplement bottle and they filled the top. Dosage is 6 a day, however, which is quite a lot when they have the cellulose capsule. I would prefer a solid tablet and no capsule, although there is no taste and I found them easy to swallow. This supplement certainly boosted my immune system so if that is what you are after, they do work well.
