That being said, each product boasts different dosages of this innovative ingredient, which means immune support is available for every health need and goal.

• If you’re looking for everyday immune support, reach for our Advanced Daily Immunity, which features 500mg of AHCC® as well as other clinically-proven, immune-balancing ingredients, to help improve your daily immune response.*
• For those who want an added boost to their immune health routine, we recommend AHCC® Immune Response. With 1g of the scientifically-validated ingredient in every serving, this supplement helps restore and rebuild your immune system.*
• Looking for even more support? The highest clinically-tested dosage of AHCC® (3g per serving), which is featured in Extra Strength AHCC®, has been shown to aid immune health and promote resistance to bacterial and viral infections.*

The key difference between these two immune health supplements is their varying doses of AHCC®. AHCC® Immune Response features 1g of AHCC® per serving and Extra Strength AHCC® features 3g of AHCC® per serving. While everybody’s health needs are different, we recommend the former to those searching for powerful daily immune support, and the latter to those looking for a highly-targeted immune boost to counteract an already-weakened immune system.*

AHCC® was first popularized in Japan, and remains the top-selling, immune-supporting specialty supplement in the country. Our goal at SHII has always been to make AHCC® and its life-enhancing benefits mainstream in the U.S. Bringing AHCC® stateside was an arduous — but necessary — process that spanned years to ensure our products were clean, efficacious, and continued to uphold the storied integrity of this innovative ingredient. The result: game-changing immune support that exceeds industry standards around the world.

AHCC® is a more potent source of alpha glucans than those found in other mainstream mushroom supplements. Alpha glucans help bolster the immune system, thus significantly improving immune response and strengthening resistance.* Additionally, AHCC® is manufactured through a patented process that helps increase absorption and enhance efficacy in the body. To add more context, most mushroom supplements are known for their poor absorption rate due to their heavier molecular weight.

AHCC® is a cultured extract that’s sourced from the mycelia of shiitake mushrooms. AHCC® has served as the subject of more than 30 human clinical trials — all of which prove this innovative ingredient helps to bolster the immune system, thus significantly improving immune response and strengthening resistance.*

Yes! Studies around AHCC®’s efficacy have been conducted at Ivy League institutions, garnering endorsements from Harvard and Yale researchers. AHCC® is backed by more than 30 human clinical trials, and has been shown to decrease the risk of infection.* It is used by over 1,000 clinics worldwide.

No. One decade-spanning clinical trial found that study participants showed consistent immune-related improvements while taking AHCC®.* There’s no such thing as building up a tolerance to AHCC®. Simply stay consistent, and the benefits will follow.

Our immune system plays a significant role in optimizing our overall health and wellbeing. Strengthening the immune system means you’re strengthening the whole body from potentially harmful bacteria that can lead to sickness. A stronger immune system means a more resilient you, every day.

When taken as part of your daily routine, AHCC® supports immune response through increasing the number of both natural killer and T cells,* helps the body combat oxidative stress,* promotes development and protection of immune cells,* and maintains peak natural killer cell activity.*

While there are recommended doses, we recommend consulting first with your licensed healthcare professional before giving supplements to your kids.

Yes! AHCC®  has not been found to cause serious side effects when used as directed, for a minimum of three weeks to start reaping its scientifically-proven benefits. If you’re still unsure, we recommend consulting your licensed healthcare professional.

Most mushroom allergies are triggered by the spores found on mushroom caps. The mycelia used in AHCC® do not have spores. Once harvested, the raw mycelia blend undergoes a fermentation process, which further protects against allergic reactions. However, we always recommend consulting your licensed healthcare professional about your individual health history.
