5 Reasons Why the Delivery Method Behind Fast-Acting Medicines Is Now Being Used for Mushrooms
Some fast-acting medicines are held against the cheek instead of swallowed. That route skips digestion and reaches the bloodstream fast.
Now Flow, an American-made pouch brand, is using that same route for three legendary functional mushrooms: Cordyceps, Lion’s Mane, and Reishi. No nicotine, no caffeine, and no stimulant crash.
Here's why.
1 - Stomach Acid Breaks Down What's Swallowed
Most people take functional mushrooms the same way: capsules, gummies, powders, or mushroom coffee. All of it gets swallowed, and anything swallowed has to get past stomach acid and digestive enzymes first.¹
That's why so many people try mushroom supplements, feel nothing, and write them off. The mushrooms weren't the problem. The route was.
2 - The Liver Takes Its Cut Next
Whatever survives the stomach still isn't in the clear. Before it reaches the bloodstream, it passes through the liver, which filters it first. Researchers call this first-pass metabolism.¹
By the time a swallowed dose reaches the blood, it's already been through two filters.
3 - The Cheek Is a Shortcut to the Bloodstream
The tissue inside the cheek is thin and packed with blood vessels. Whatever is held there can pass straight into the blood, skipping both the stomach and the liver's first pass.¹ This is called buccal absorption, and it's the reason some fast-acting medicines use this route.
A Flow pouch sits under the lip, against the gums and cheek. It's designed to be felt in about 5 minutes.
SAME MUSHROOMS. DIFFERENT DOOR.
4 - These 3 Mushrooms Are Worth Getting Right
Cordyceps made headlines when a record-breaking 1993 track team credited it. In a placebo-controlled trial, adults who took Cordyceps for 12 weeks improved measures of their exercise capacity.²
Lion's Mane was prized by Buddhist monks for focus during meditation. In a placebo-controlled study, healthy young adults were faster on a focus test after a single dose.³
Reishi was treasured by ancient Chinese emperors and called the mushroom of immortality. In a placebo-controlled trial, a Reishi extract eased stress-related fatigue.⁴
That's energy, focus, and calm. Ingredients with that kind of history deserve better than digestion.
ENERGY. FOCUS. CALM.
CORDYCEPSLION'S MANEREISHI
Functional mushrooms. Not the kind that get you high.
