Tea for Guys Ingredients
Every Tea for Guys blend is built from whole-plant ingredients chosen for clinical evidence, clean sourcing, and real function. No proprietary pixie-dust blends, no fillers, no artificial flavors - just potent botanicals working together to support testosterone, energy, metabolism, and daily performance.
Why Every Ingredient Matters
At Tea for Guys, ingredient selection is not an afterthought - it is the product. We start with published clinical research and work backward to source the highest-quality botanical form of each ingredient available. Every herb, root, leaf, and fruit in our blends has been selected for a specific physiological purpose supported by peer-reviewed evidence.
We source directly from established growing regions known for optimal soil composition, altitude, and traditional cultivation expertise. Our Ashwagandha comes from India, our Yerba Mate from South America, our Green Tea from Japanese highlands. We never bulk-buy generic commodity herbs. Each lot is tested for heavy metals, pesticide residues, and microbial contamination before it enters any blend.
Transparency matters. You will never find a "proprietary blend" weight on our labels that hides individual dosages. We believe you deserve to know exactly what you are drinking and why. The sections below break down every single ingredient across our three core blends - what it does, where it comes from, and the research behind it. This is functional tea, built for men who demand more from what they consume.
Testosterone & Vitality Support
The Vitality Blend is engineered to support healthy testosterone levels, libido, and male hormonal balance through six evidence-backed botanicals.
Ashwagandha
In our: Vitality Blend Origin: India
What it does: Ashwagandha is a powerful adaptogen that helps reduce cortisol, support testosterone production, and improve stress resilience. It has been used in Ayurvedic medicine for over 3,000 years to enhance male vitality.
A randomized, double-blind, placebo-controlled crossover study found that ashwagandha extract gave a 14.7% greater increase in testosterone than placebo over eight weeks in overweight men aged 40 to 70; cortisol did not differ between groups. (PMID: 30854916)
Horny Goat Weed
In our: Vitality Blend Origin: China
What it does: Horny Goat Weed contains icariin, a prenylated flavonoid that supports nitric oxide production and phosphodiesterase inhibition, promoting healthy blood flow and sexual function.
In a lab study, icariin, the main active compound in Epimedium, inhibited the PDE5 enzyme, though about 80 times more weakly than sildenafil; this has not been shown in humans. (PMID: 18778098)
Saw Palmetto
In our: Vitality Blend Origin: United States
What it does: Saw Palmetto supports prostate health and helps maintain a favorable testosterone-to-DHT ratio by inhibiting 5-alpha-reductase activity.
Serenoa repens is the supplement men most often use for lower urinary tract symptoms; most clinical studies suggest a modest benefit, but recent ones are less consistent and its clinical value remains undefined. (PMID: 16930496)
Rooibos
In our: Vitality Blend Origin: South Africa
What it does: Rooibos is a naturally caffeine-free red bush herb rich in aspalathin and quercetin. It forms the smooth, slightly sweet base of the Vitality Blend and supports oxidative balance, healthy glucose metabolism, and cardiovascular function in men.
Aspalathus linearis (rooibos) is a caffeine-free South African herbal tea, drunk daily in its home region for generations, and it carries the Vitality blend without adding caffeine.
Turmeric
In our: Vitality Blend Origin: India
What it does: Turmeric delivers curcumin, a potent anti-inflammatory compound that supports joint health, reduces exercise-induced inflammation, and protects Leydig cells from oxidative stress that can impair testosterone production.
Curcumin has been shown to attenuate inflammatory cytokines including TNF-alpha and IL-6, both of which are implicated in testosterone suppression during chronic stress or overtraining. Its antioxidant capacity further supports testicular health and overall endocrine function. (PMID: 29065496)
Ginger
In our: Vitality Blend Origin: Indonesia
What it does: Ginger enhances testosterone synthesis, supports digestion, and delivers powerful anti-inflammatory and antioxidant compounds including gingerols and shogaols.
A 2018 review found that ginger raised testosterone in animal studies, mainly under oxidative stress, but the effect has not been confirmed in humans. (PMID: 30360442)
Energy & Focus
The Energy Blend delivers clean, sustained energy and sharp mental focus without jitters or crashes - powered by six natural performance ingredients.
Yerba Mate
In our: Energy Blend Origin: Argentina
What it does: Yerba Mate provides balanced, sustained caffeine alongside theobromine and polyphenols, delivering smooth energy without the spike-and-crash profile of coffee.
Ilex paraguariensis is a South American holly leaf, traditionally brewed as a caffeinated drink that also contains theobromine. In a small crossover trial, yerba mate capsules taken an hour before exercise increased fat oxidation by 24% at moderate intensities. (PMID: 25342955)
Guayusa
In our: Energy Blend Origin: Ecuador
What it does: Guayusa is an Amazonian holly leaf that delivers clean caffeine alongside L-theanine and chlorogenic acids, promoting alert focus with a calm, jitter-free energy profile.
Ilex guayusa is a caffeinated holly leaf from the Ecuadorian Amazon, traditionally brewed by Kichwa communities as a daily morning drink.
Siberian Ginseng
In our: Energy Blend Origin: Russia
What it does: Siberian Ginseng is an elite adaptogen that enhances stamina, reduces mental fatigue, and supports the body's resistance to physical and environmental stress.
Clinical trials have demonstrated that the active glycoside compounds in Siberian Ginseng improve endurance performance, reduce perceived exertion, and enhance oxygen utilization during sustained physical activity. Its adaptogenic mechanism operates through modulation of the hypothalamic-pituitary-adrenal axis, promoting balanced cortisol output. (PMID: 20920564)
Lemon Myrtle
In our: Energy Blend Origin: Australia
What it does: Lemon Myrtle provides a bright citrus flavor profile while delivering potent antimicrobial and antioxidant compounds, including a high natural concentration of citral.
Backhousia citriodora (lemon myrtle) is an Australian native leaf rich in citral, the compound behind its strong lemon flavor, and it is used here for taste.
Licorice Root
In our: Energy Blend Origin: Turkey
What it does: Licorice Root adds natural sweetness while supporting adrenal function, digestive comfort, and throat-soothing anti-inflammatory activity through its active compound glycyrrhizin.
Glycyrrhiza glabra (licorice root) is a naturally sweet root with a long history in traditional herbal medicine; in the Energy Blend it adds sweetness without added sugar.
Dragon Fruit
In our: Energy Blend Origin: Vietnam
What it does: Dragon Fruit (pitaya) delivers prebiotic fiber, betalain antioxidants, and essential micronutrients including iron - supporting sustained energy, gut health, and vibrant natural color.
Hylocereus undatus (dragon fruit) is the fruit of a climbing cactus, used here for its mild sweetness and color.
Metabolism & Fasting Support
The Fasting Blend is designed to support intermittent fasting windows, thermogenic metabolism, and appetite management - with zero calories and five targeted ingredients.
Green Tea
In our: Fasting Blend Origin: Japan
What it does: Green Tea delivers EGCG catechins and gentle caffeine that boost thermogenesis, enhance fat oxidation, and support metabolic rate during fasting windows without breaking a fast.
Epigallocatechin gallate (EGCG), the dominant catechin in Camellia sinensis, has been shown to increase 24-hour energy expenditure and fat oxidation in controlled metabolic studies. Its synergy with naturally occurring caffeine amplifies thermogenic output while L-theanine content prevents overstimulation. (PMID: 21115335)
Peppermint
In our: Fasting Blend Origin: United States
What it does: Peppermint naturally suppresses appetite, soothes the digestive tract, and provides a refreshing menthol flavor that makes fasting more comfortable and sustainable.
Mentha piperita (peppermint) is a mint-family herb traditionally drunk as a tea after meals.
Fenugreek
In our: Fasting Blend Origin: India
What it does: Fenugreek seed supports healthy blood sugar regulation, improves insulin sensitivity, and provides soluble fiber that helps reduce hunger and stabilize energy during fasted states.
Trigonella foenum-graecum has been shown to improve fasting blood glucose levels and insulin sensitivity in multiple randomized controlled trials. Its galactomannan fiber and 4-hydroxyisoleucine content slow gastric emptying and modulate carbohydrate metabolism, helping maintain stable energy and satiety during fasting windows. (PMID: 19809809)
Hibiscus
In our: Fasting Blend Origin: Nigeria
What it does: Hibiscus provides a tart, cranberry-like flavor while delivering anthocyanin antioxidants that support healthy blood pressure, lipid metabolism, and cardiovascular function.
Hibiscus sabdariffa extract has been clinically shown to reduce systolic and diastolic blood pressure in pre-hypertensive and mildly hypertensive adults. Its anthocyanin and organic acid content also supports LDL cholesterol reduction and liver enzyme health, making it a powerful cardiovascular ingredient in a zero-calorie format. (PMID: 20018807)
Barberry
In our: Fasting Blend Origin: Iran
What it does: Barberry delivers berberine, a plant alkaloid that supports glucose metabolism, lipid profile, and AMPK activation - particularly valuable during fasting windows when metabolic flexibility is the goal.
Berberis vulgaris (barberry) is a shrub whose tart berries and root bark have a long history in traditional Persian and European herbal medicine.
Sleep & Recovery
Our Nighttime Blend is engineered for restorative sleep - the single most powerful recovery tool a man has. Deep, uninterrupted sleep is when testosterone peaks, muscle repairs, and the brain consolidates everything from the day. These six botanicals work synergistically to calm the nervous system, reduce sleep-onset latency, and promote slow-wave sleep without the grogginess of pharmaceuticals.
Skullcap
In our: Nighttime Blend Origin: United States
What it does: Skullcap (Scutellaria lateriflora) is a nervine herb that modulates GABA receptors to reduce nervous tension and promote mental calm. It eases the racing thoughts that keep men staring at the ceiling long past bedtime.
American skullcap has been used for centuries as a mild sedative and anxiolytic in traditional Western herbalism.
Chamomile
In our: Nighttime Blend Origin: Egypt
What it does: Chamomile (Matricaria chamomilla) is one of the most well-studied calming herbs on the planet. Its apigenin content binds benzodiazepine receptors in the brain, gently promoting sleepiness and reducing anxiety.
Beyond its reputation as a gentle bedtime tea, chamomile has real clinical backing. Apigenin - the primary bioactive flavonoid - acts as a mild tranquilizer by modulating GABAergic neurotransmission. A randomized controlled trial in adults with generalized anxiety disorder showed that long-term chamomile use significantly reduced moderate-to-severe GAD symptoms and lowered systolic blood pressure (PMID: 27912875).
Hops
In our: Nighttime Blend Origin: Germany
What it does: Hops (Humulus lupulus) contains the prenylated flavonoid 2-methyl-3-buten-2-ol, which acts on GABA receptors to reduce sleep-onset latency. It is especially effective when combined with chamomile and passionflower for compounding sedative benefit.
While most people associate hops with beer, the female flower cones have been used medicinally as a sleep aid since at least the 9th century. The volatile compound 2-methyl-3-buten-2-ol increases during drying and is believed to be the primary sedative agent.
Damiana
In our: Nighttime Blend Origin: Mexico
What it does: Damiana (Turnera diffusa) is a traditional nervine that supports relaxation, mood stability, and a calm transition into sleep. Its mild anxiolytic profile pairs well with chamomile and hops in the Nighttime Blend without producing morning sedation.
Turnera diffusa has been used across Central America for centuries as a calming, mood-supporting herb. Modern research attributes its effects to flavonoids that modulate GABA tone and reduce evening sympathetic arousal, helping the body settle into restorative sleep without the dependency risks associated with synthetic sedatives (PMID: 19501274).
Passionflower
In our: Nighttime Blend Origin: India
What it does: Passionflower (Passiflora incarnata) boosts brain GABA levels and modulates the sleep-wake cycle, making it particularly effective for men whose stress or cortisol levels interfere with restful sleep.
Passionflower has a long history of use in Ayurvedic and Native American traditions for anxiety and insomnia. The chrysin and vitexin flavonoids it contains are believed to produce its calming effects through GABAergic modulation. A double-blind, placebo-controlled study showed that passionflower tea consumed over a seven-day period significantly improved subjective sleep quality measures in adults with mild sleep irregularities (PMID: 21294203).
Rooibos
In our: Nighttime Blend Origin: South Africa
What it does: Rooibos (Aspalathus linearis) is a naturally caffeine-free South African red bush herb rich in aspalathin and quercetin. As the soothing base of the Nighttime Blend, it provides a smooth, slightly sweet body and broad antioxidant support that pairs well with the sleep-promoting botanicals around it.
Rooibos has been consumed in southern Africa for centuries as a calming, caffeine-free evening beverage.
Sourcing & Quality Standards
Every ingredient in a Tea for Guys blend is certified organic or sourced from wild-harvested, pesticide-free environments. We refuse to cut costs with conventional-grade botanicals. Organic certification matters because the herbs you steep in hot water release everything they contain - including any pesticide residues, heavy metals, or synthetic fertilizer byproducts present in conventionally grown crops. Our supply chain prioritizes USDA Organic and EU Organic-certified farms, and every lot we purchase comes with a current certificate of organic compliance.
Third-party testing is not optional at Tea for Guys - it is a foundational requirement. Each incoming batch of raw material undergoes independent laboratory analysis for microbial contaminants (E. coli, Salmonella, yeast, mold), heavy metals (lead, arsenic, cadmium, mercury), and pesticide residue panels. We also verify active-compound potency to ensure that the ashwagandha you drink actually contains the withanolide concentration we promise on the label. Our testing partners are ISO 17025-accredited facilities, and we maintain certificates of analysis (COAs) for every production run.
Sustainability guides every sourcing decision. We partner with farms that employ regenerative agriculture practices - cover cropping, composting, and crop rotation - because healthy soil produces more potent botanicals and protects the land for future harvests. Our packaging uses biodegradable tea sachets and recyclable outer pouches. We believe that a product built to support men's long-term health should not come at the expense of the planet's long-term health. From field to cup, every link in our supply chain is designed to be transparent, traceable, and responsible.

Frequently Asked Questions
Are all Tea for Guys ingredients certified organic?
Yes. Every botanical in our five blends is sourced from USDA Organic or EU Organic-certified farms. Where certified organic supply is not available for a particular origin, we source from verified pesticide-free, wild-harvested environments and confirm purity through independent laboratory testing. We never use conventionally grown herbs treated with synthetic pesticides or fertilizers.
Do any of your blends contain common allergens?
Our blends are free from gluten, dairy, soy, nuts, eggs, and shellfish. They contain no artificial flavors, colors, sweeteners, or preservatives. All blends are caffeine-free with the exception of the Energy Blend (which contains natural caffeine from yerba mate and guayusa) and the Fasting Blend (which contains moderate natural caffeine from green tea). If you have a known allergy to any plant in the Asteraceae/Compositae family (which includes chamomile), please consult your healthcare provider before consuming the Nighttime Blend.
Where do you source your ingredients?
We source each ingredient from the region where it grows best and has the strongest tradition of use. Our ashwagandha comes from India, horny goat weed from China, Siberian Ginseng from Russia, yerba mate from Argentina, hops from Germany, and chamomile from Egypt - among many other origin-specific selections. Every supplier is vetted for organic certification, sustainable farming practices, and consistent active-compound potency. We maintain full traceability from farm to finished sachet.
Why these specific botanicals instead of synthetic supplements?
Every ingredient in a Tea for Guys blend was selected based on peer-reviewed clinical evidence, traditional use spanning centuries, and synergistic compatibility with the other herbs in its blend. Whole-plant botanicals contain complex matrices of bioactive compounds - flavonoids, saponins, polyphenols, alkaloids - that often work together in ways isolated synthetic compounds cannot replicate. We chose the tea format specifically because hot-water extraction is one of the most efficient methods for releasing these water-soluble bioactives, delivering them in a form your body can readily absorb.
How do you verify potency and purity through third-party testing?
Every incoming batch of raw material is sent to an independent, ISO 17025-accredited laboratory before it enters production. Testing covers microbial contaminants (E. coli, Salmonella, total aerobic count, yeast, and mold), heavy metals (lead, arsenic, cadmium, mercury), a broad pesticide residue panel, and active-compound assay to verify potency - for example, withanolide content in ashwagandha and ginsenoside levels in ginseng. Batches that do not meet our specifications are rejected. We maintain certificates of analysis for every production run and are happy to share them with customers upon request.
