Which countries do you ship your products to?

We ship our products globally from our warehouse (based in UK). As different countries have different regulations, it is impossible for us to guarantee that you will receive your order unopened or without extra taxes and duty fees. It is your responsibility to be aware of the relevant laws of your country. NOTE: We ship our orders from UK. Possible custom and duty charges will occur especially for Australian orders.

Mushrooms and pregnancy

During pregnancy it is important to use caution and listen to the body when consuming strong natural herbs and mushrooms. This is also the case when using Four Sigma Foods products. Traditionally, however, all medicinal mushrooms have been used during pregnancy to support the mother’s health and energy levels. Some adaptogenic herbs should be totally fine for a pregnant woman, but some are known to enhance blood flow to the uterus. Please consult your healthcare professional if you have further concerns.

What is the estimated delivery time?

20 days. You may receive your order earlier, but prepare yourself mentally for a 20-day wait. . . . I know, that’s kinda long. Our low prices and rare selection of certain herbs are possible due to our warehouse’s location near the products’ origin, which makes the transportation distance a bit longer. We are constantly trying to work on this one, but for a small company like FSF, it’ll take some time to make a change happen. If you are in a hurry, please see if there’s one of our resellers near you. 

One of my products was damaged. Can I get a refund?

We hope our customers will understand that when we ship paper boxes around the world, sometimes corners might get curled. The sachets inside and the actual Instant beverage powders are still usable 99.99% of the time. If you think there are problems with the actual products, then send us a description along with photos by e-mail, and we’ll check it out. We will happily deal with these incidents on a case-by-case basis and promise not to leave you disappointed.

Are your products illegal? Would using them be considered doping?

None of our products are on the World Anti-Doping Agency’s (WADA’s) prohibited list, and they are legal all around the world. Most medicinal mushrooms and adaptogenic herbs have been used for over 5,000 years, so it is very unlikely that they will ever make the list or become illegal.

Are your products suitable for vegans? What about people with allergies?

Yes. All our products are vegan, wheat-free, gluten-free, cholesterol-free, sugar-free, soy-free, peanut-free, and nut-free. They also are free from pesticides, additives, and other zombie ingredients that the GMO people promote.

Where do your products grow?

Just like all good superfood manufacturers, we can’t get all our ingredients from one single farm or area if we want to create ideal solutions. We need to source products from all over the world, from the places where they originally grew and/or where there’s an exhaustive history and knowledge of using these foods and herbs. For example, our Chaga is wildcrafted in rural Siberia, our coconut products are collected from Mindanao (an island in the Philippines known for its rich soil), our kava kava is grown on a tropical island in Vanuatu, our yohimbe is brought from Cameroon (the area in Central Africa where it was originally used), and the list goes on. We’re constantly looking for new quality suppliers and visiting existing farmers/producers.

How much of your products can I use each day?

All of our products are quite strong, but still tonic. This means that there’s no real health danger in overdosing. Just remember that a high enough dose of anything, including water and apples, can be toxic for your body. There’s still no need to take breaks or adopt cyclical consumption patterns. Rather, it’s wise to use the products consistently, to beat minor illnesses before they arise. Treating the cause is always healthier than curing the symptoms (such as by drinking the products only after you’ve become ill).

Personally, we recommend starting the use of new (even tonic) products with slightly smaller-than-normal dosages (e.g., one sachet of mushrooms) to get a feel for their potency and to give the body a chance to adapt to the new intelligence coming into it. After a few weeks of taking gradually increasing dosages, feel free to go ahead and drink as much as you like each day. Just listen to your body and your cravings, and all should be fine.
