Craving control

SOLO Control

A blend built to quiet cravings and reduce mindless snacking — gently diluting the urge, never harshly suppressing appetite.

01Nootropic

L-Theanine

100mg

An amino acid found naturally in green tea. It promotes a state of "calm alertness" by supporting alpha brain-wave activity, taking the sharp, jittery edge off caffeine so you feel steady and focused rather than wired.

Full breakdown
What it is

A non-protein amino acid best known for producing a calm, relaxed state without drowsiness.

Derived from

Naturally concentrated in the leaves of the tea plant (Camellia sinensis); supplement-grade L-theanine is produced by fermentation or extracted from green tea.

How it works

Raises alpha brain-wave activity and modulates GABA, dopamine and serotonin, promoting relaxation while blunting the anxious, jittery response to caffeine.

02Adaptogen

Rhodiola Rosea

50mg

A high-altitude adaptogenic herb used for centuries to combat fatigue. It helps the body adapt to physical and mental stress, easing the burnout and tiredness that so often drive stress-eating and late-night snacking.

Full breakdown
What it is

An adaptogen — a plant traditionally used to help the body resist physical and mental stress.

Derived from

The root of Rhodiola rosea, a flowering plant native to cold, high-altitude regions of Europe and Asia; typically standardized to rosavins and salidroside.

How it works

Helps modulate the cortisol stress response and monoamine neurotransmitters, associated with reduced fatigue and improved stress resilience.

03Mineral

Chromium

100mcg

An essential trace mineral that supports insulin function and healthy blood-sugar balance. Steadier blood sugar means fewer sharp dips — the crashes that trigger sudden hunger and intense cravings between meals.

Full breakdown
What it is

An essential trace mineral the body needs in only microgram amounts.

Derived from

Found in foods like broccoli, whole grains and brewer's yeast; supplemented here as chromium picolinate, a well-absorbed form.

How it works

Enhances insulin signaling to help cells take up glucose, supporting steadier blood sugar, which research links to fewer carbohydrate cravings.

04Botanical

Gymnema Sylvestre

75mg

Known in Ayurveda as gurmar, the "sugar destroyer." Compounds in the leaf can temporarily dull the perception of sweetness on the tongue, blunting the appeal of sugary foods and helping quiet the urge to reach for a sweet treat.

Full breakdown
What it is

A woody climbing shrub used for centuries in traditional Ayurvedic medicine.

Derived from

The leaves of Gymnema sylvestre, native to the tropical forests of India and Africa; the active compounds are gymnemic acids.

How it works

Gymnemic acids temporarily bind to sweet-taste receptors on the tongue, dulling the perception of sweetness and reducing the pull of sugary foods.

05Vitamin

Vitamin B6

2mg

A cofactor in the production of mood-regulating neurotransmitters like serotonin and dopamine. It supports balanced mood and healthy energy metabolism, helping you stay even-keeled through the day.

Full breakdown
What it is

A water-soluble vitamin (pyridoxine) involved in more than 100 enzyme reactions.

Derived from

Naturally present in poultry, fish, potatoes and bananas; supplemented as pyridoxine or the active pyridoxal-5-phosphate (P5P) form.

How it works

Acts as a cofactor in producing serotonin, dopamine and GABA, supporting balanced mood and the conversion of food into usable energy.

06Vitamin

Vitamin B12

500mcg

Essential for red-blood-cell formation and healthy nervous-system function. It helps convert food into usable energy, supporting sustained mental and physical stamina without a stimulant spike.

Full breakdown
What it is

A water-soluble vitamin (cobalamin) essential for nerve and blood-cell health.

Derived from

Found almost exclusively in animal foods; the supplemental form is produced through bacterial fermentation (as methyl- or cyanocobalamin).

How it works

Required for red-blood-cell formation, DNA synthesis and myelin maintenance, supporting steady energy and healthy nervous-system function.

Sources: NIH Office of Dietary Supplements, Vitamin B12 Fact Sheet.

07Energy

Caffeine

50mg

A modest, measured dose — roughly half a cup of coffee. Just enough for a clean lift and mild appetite support, and deliberately paired with L-theanine to smooth out the response so there's no spike and no crash.

Full breakdown
What it is

The world's most widely consumed natural stimulant.

Derived from

Naturally occurring in coffee beans, tea leaves, cacao and guarana; dosed here at a controlled 50mg (about half a cup of coffee).

How it works

Blocks adenosine receptors to reduce the sensation of fatigue and sharpen alertness; paired with L-theanine to smooth the curve and prevent the crash.
