Mushroom Science
What is Headwater?
Caffeine-free performance hydration powered by certified-organic mushroom extracts
Headwater is a precision-formulated Performance Fuel™ beverage designed to support cognitive endurance, steady energy, and recovery—naturally, without caffeine, high sugar, or artificial stimulants.
Each Headwater variety contains one certified-organic mushroom extract: Lion’s Mane fruiting-body extract in Tangerine Lion’s Mane or Chaga extract in Blueberry Chaga, plus L-theanine and vitamin C.
22 calories, 2 g sugar, 500 mg mushroom extract, and 100 mg L-theanine per 12-ounce can.
Is Headwater backed by science?
Yes - through ingredient-level research and formulation discipline
-
Formulated using well-studied functional mushrooms, including Lion’s Mane and Chaga
-
Built on peer-reviewed research examining cognitive function, stress response, and antioxidant activity
-
Uses Lion’s Mane fruiting-body extract and Chaga extract to provide studied mushroom bioactive compounds.
-
Designed to support focus, resilience, and recovery without caffeine or stimulants
Headwater does not claim to treat or cure — it is designed using ingredients supported by modern nutritional and mycological research.
The linked research concerns individual ingredients, not the finished Headwater beverage. Preparations, amounts and findings vary. Lion’s Mane cognition studies have reported differing results: Mori (2009) and Surendran (2025).

Lion’s Mane Fruiting-Body Extract and Chaga Extract
Lion’s Mane extract is made from the mushroom’s fruiting body. Chaga extract is made from the dense growth known as a sterile conk, which differs from a mushroom fruiting body.
These mushroom materials contain studied bioactive compounds, including:
-
Beta-glucans in both Lion’s Mane and Chaga
-
Hericenones in Lion’s Mane fruiting bodies
-
Polyphenols and triterpenes in Chaga
Headwater uses one certified-organic mushroom extract per variety, without myceliated-grain fillers.
Lion’s Mane: How It Supports the Brain
A. Supports NGF-related pathways (nerve growth factor)
Lion’s Mane contains compounds being studied for their ability to activate pathways associated with nerve growth factor (NGF). NGF is a protein your body uses to support certain neurons—especially those involved in memory formation and learning.
Why this matters: NGF-sensitive neurons play a key role in learning and recall. Supporting NGF-related activity may help maintain healthy neuron function over time, including as you age.
B. Helps maintain synaptic plasticity (how the brain adapts)
Synaptic plasticity is your brain’s ability to strengthen and reorganize connections between neurons. This flexibility supports learning, memory, creativity, and adaptability.
Why this matters: When synaptic plasticity is supported, your brain is better able to adapt—supporting focus, problem-solving, and steady mental performance. Lion’s Mane contains compounds being studied for their role in cellular processes linked to plasticity.
C. Provides beta-glucans for immune balance
Beta-glucans are natural fibers found in the cell walls of mushrooms.
Why this matters: Your immune system has receptors that respond to beta-glucans in ways associated with balanced immune activity—supporting steadiness rather than overstimulation. Balanced immune function supports overall resilience and can help you feel consistently well day to day.
Chaga: How It Supports Cellular Protection & Recovery
A. High antioxidant activity for everyday oxidative stress
Your cells constantly face oxidative stress—the natural “wear and tear” from metabolism, exercise, and daily life. Chaga contains antioxidant compounds, including polyphenols, melanin complexes, and triterpenes.
Why this matters: Antioxidants help neutralize free radicals so they create less strain on cells. This supports daily resilience, recovery, and long-term cellular health.
B. Beta-glucans that support immune balance and communication
Like Lion’s Mane, Chaga is rich in beta-glucans—natural fibers found in mushroom cell walls.
Why this matters: Beta-glucans interact with immune receptors involved in normal immune signaling, supporting balanced immune activity rather than overstimulation. That balance supports overall resilience and consistent day-to-day well-being.
C. Compounds studied for supporting stress resilience
Chaga contains bioactive compounds (including triterpenes and polyphenols) that are being studied for their role in supporting the body’s response to physical and environmental stressors.
Why this matters: Supporting healthy stress-response pathways can help you stay steady through demanding weeks—physically and mentally—without relying on stimulants.
Why Extracts Matter (Not Raw Powder)
Mushroom cell walls contain chitin, a structural material. Extraction helps separate and concentrate selected bioactive compounds from mushroom material.
Why this matters: Raw mushroom powders and extracts are different ingredients. The extraction process influences which compounds are present in the finished extract.
-
Water extraction is commonly used to obtain water-soluble compounds, including beta-glucans.
-
Alcohol extraction can obtain certain less water-soluble compounds, including some triterpenes.
Mushroom Extracts and Mycelium on Grain
Some mushroom ingredients are made from mycelium grown on grain. When grain remains in the finished ingredient, its starch can dilute the proportion of mushroom material and beta-glucans.
Why this matters: Mycelium itself can contain useful bioactive compounds. It should not be confused with residual grain in a myceliated-grain ingredient. Headwater uses Lion’s Mane fruiting-body extract and Chaga extract, without myceliated-grain fillers.
Ingredient Integrity: Why Every Component Is There
L-Theanine
-
A naturally occurring amino acid found in green tea.
-
Why it matters: L-Theanine supports calm, steady alertness by promoting alpha-wave brain activity - the same state seen in focused engagement without stress.
Vitamin C
-
A well-known antioxidant included in both Headwater varieties.
-
Why it matters: Vitamin C supports cellular defense and recovery alongside the mushroom extract in each variety.
Natural Fruit Flavors & all natural agave
-
These ingredients give Headwater its clean, crisp, fruit-forward flavor and light sweetness.
-
Why it matters: Headwater delivers the functional benefits of mushrooms while tasting bright and refreshing, with no mushroom taste.
What Headwater Does Not Contain - and Why
-
No caffeine: Stimulation isn’t the goal — steady mental performance is.
-
No artificial sweeteners: Headwater uses all natural agave for light sweetness, with 2 g sugar per 12-ounce can.
-
No myceliated-grain fillers: Headwater uses Lion’s Mane fruiting-body extract and Chaga extract.
