Researched doses

Certified pure & potent
It’s important that your supplement contains everything it should — the listed ingredients at the listed potencies — and nothing it shouldn’t, like contaminants or adulterants. That’s why every finished product undergoes seven rigorous quality assurance tests.
What is AHCC?
AHCC is derived from several subspecies of mushroom mycelia. Developed in Japan, AHCC is backed by 29 positive studies published in peer-reviewed scientific journals recognized by the National Institutes of Health.
Unlike most other mushroom extracts, AHCC has a low molecular weight of just 5,000 daltons and is rich in alpha-glucans, which enhances its absorption and effectiveness.

Trust, Efficacy, and Our Promise
We are the only brand in the supplement industry that guarantees every ingredient in every product is supported by human studies and delivered at doses consistent with clinical research.
No exceptions, no compromises.
ProtectivelyPackaged in the USA
We package nearly all our products in glass bottles with metal lids for one simple reason: glass and metal provide the best protection against light, oxygen, and moisture — all factors that can degrade vitamins, minerals, botanicals, and other nutraceuticals, reducing their potency and freshness.

FAQS
Are your products vegetarian?
Are your products vegetarian?
Whenever possible, Quality of Life formulates our products to be vegetarian and uses vegetarian capsules made from vegetable cellulose. However, many of the most-researched nutritional ingredients come from animal sources, such as vitamin D3, chondroitin, collagen, and Neptune krill oil. Because we prioritize clinical efficacy, when faced with a choice between a vegetarian form (like vitamin D2) and a more scientifically validated animal-derived form (like vitamin D3), we choose the option backed by stronger research to ensure the best results.
If I am allergic to mushrooms, can I take AHCC?
If I am allergic to mushrooms, can I take AHCC?
Allergies to mushrooms are usually linked to exposure to mushroom spores, which come from the fruiting body — the top part of the mushroom. However, AHCC is derived from the mycelia, or the root-like part of the mushroom, which contains no spores. Additionally, during manufacturing, the raw material undergoes fermentation that breaks down high molecular weight molecules — which are hard to digest — into low molecular weight compounds. This process further reduces any allergenic potential.
Many people who believe they are allergic to mushrooms have successfully taken AHCC. However, if you’re concerned, please consult a healthcare professional specializing in natural products. You can also start AHCC very gradually: begin with a quarter of a capsule placed on the tip of your tongue. If you don’t experience itching or other allergic reactions, gradually increase your dose to 2 to 6 capsules per day over several days.

When is the best time to take your products?
When is the best time to take your products?
Some supplements are best taken on an empty stomach, while others work better with food. Each Quality of Life product label clearly indicates the best time to take it under “Suggested Use,” and we also provide detailed directions on each product page here on our site. That said, the best time to take your supplements is simply when you remember to take them! When it comes to results, consistency matters more than exact timing.
