Noomadic's Cordyceps Mushrooms are grown in China, where the highest quality mushrooms are grown. Contrary to popular belief, the best mushrooms come from China, and not from the USA. There are a few reasons for that:

1. China uses traditional preparations. The USA has just started catching on to the fact that mushrooms can be a essential part in our health. China has been preparing mushrooms for centuries. Almost all products grown in the USA are not made from Mushrooms but inferior mycelium on grain.
2. It's more cost efficient. If you want a hot water  extract, made of fruiting bodies and made in the USA, its going to cost an extreme amount. In fact, there isn't any company who provides a hot water extract, fruiting body mushroom extract grown in the USA.

We know China has a bad reputation when it comes to smog and pollution. Our harvesting area is far away from any of that, and we grow our Cordyceps in a controlled environment.

We also take extra precautions and not only test our Cordyceps once, but twice for heavy metals and other chemicals,

The expiry date is two years after the production date. Typically you will have 1.5 years to consume your Cordyceps before it expires.

You can find the expiry date stamped on the bottom of the bottle.

Yes. Typically companies test their products for heavy metals and chemicals once. However; we test twice, just to ensure they are safe for our customers.

One of the most common misconceptions is that Cordyceps sinensis (The Caterpillar Fungus) is the superior version of Cordyceps. This simply isn’t true as Cordyceps militaris has been found to produce as much as 90x more cordycepin and overall has equal or better therapeutic potential. Not only that but there is virtually no Cordyceps sinensis for sale in North America as it costs upwards of $20,000 / KG. If you see a product labeled as Cordyceps sinensis, it is more than likely mislabeled.

When it comes to Mushroom Extracts it is essential you find one that is hot water extract. All clinical trials have used this type of mushroom extract and therefore any mushrooms that are not a hot water extract have not been proven to have any efficacy. Furthermore, hot water extracted mushrooms are the only mushrooms which unlock the beta-d-glucans (polysaccharides) trapped in the chitin (cell walls) without damage. The body is not able to digest chitin, so if the chitin is not broken down properly the beta-d-glucans will never be bio-available. Thus, why a hot water and alcohol extraction is the only validated process for any mushroom extract.
