Title

  • L-Dopa

  • N-Acetyl Cysteine

  • Vitamin B-Complex

  • Pre & Probiotics

  • Vitamin C

What It Is

L-Dopa is a naturally occurring amino acid that the brain converts directly into dopamine. It is sourced from Mucuna pruriens, a tropical legume known for its unusually high concentration of natural L-Dopa. Mucuna pruriens has been studied for its effects on mood, movement, and motivation because of this rich dopamine precursor content.

How It Helps

During withdrawal, dopamine levels often drop, which can lead to low motivation, fatigue, and difficulty feeling normal pleasure. L-Dopa helps replenish dopamine production at the source by giving the brain the raw material it needs to rebuild this pathway. As dopamine levels stabilize, users often experience improved energy, better motivation, and a more balanced emotional state.

What It Is

N-Acetyl Cysteine (NAC) is a stable, bioavailable form of the amino acid cysteine and a key precursor to glutathione, the body's primary antioxidant. It is used in clinical research for its detoxifying effects and for its ability to regulate glutamate, a neurotransmitter involved in stress, cravings, and cognitive function. Because of these properties, NAC is often used to support both metabolic recovery and mental clarity.

What It Is

Vitamin B Complex is a group of essential water soluble vitamins that play central roles in energy production, nervous system function, neurotransmitter synthesis, and cellular metabolism. These vitamins are depleted quickly during periods of stress, poor sleep, and heavy substance use. Replenishing them supports healthier brain function and smoother metabolic activity throughout the day.

How It Helps

B vitamins help kick start energy production by supporting the conversion of food into usable cellular energy. They also fuel the synthesis of key neurotransmitters involved in mood, focus, and motivation, all of which tend to run low during withdrawal. By restoring these pathways early in the day, B Complex helps reduce fatigue, improve mental steadiness, and give the body the metabolic support it needs to function normally again.

Supporting Studies

What It Is

Prebiotics are specialized plant fibers that feed beneficial bacteria in the gut, while probiotics are live microorganisms that help restore a healthy gut microbiome. Together, they support digestion, nutrient absorption, immune function, and the production of neurotransmitters like serotonin and dopamine. Because the gut and brain communicate constantly, a balanced microbiome plays a major role in mood, stress regulation, and overall recovery.

How It Helps

Pre and probiotics help reset the gut environment after long periods of physical stress and disrupted digestion. A healthier gut supports smoother energy production, better nutrient absorption, and more stable mood throughout the day. By improving serotonin and dopamine signaling from the gut, they help reduce withdrawal related irritability and support a clearer, more grounded start to the morning.

Supporting Studies

What It Is

Vitamin C is a powerful antioxidant that supports immune function, tissue repair, and cellular defense against oxidative stress. It plays a key role in maintaining healthy adrenal glands, which regulate stress hormones. Vitamin C is also involved in the synthesis of neurotransmitters, including those that influence mood, focus, and motivation.

How It Helps

Vitamin C helps counter the oxidative strain that builds up from long term substance use and the early stages of withdrawal. By supporting the adrenal system, it promotes steadier energy and helps regulate the stress response that often spikes in the morning. Its antioxidant effects also assist in stabilizing mood and supporting the body’s natural recovery processes throughout the day.

Afternoon Blend

Title

  • L-Tyrosine

  • L-Theanine

  • Ashwagandha

  • N-Acetyl Cysteine

  • Vitamin C

What It Is

L-Tyrosine is an amino acid that serves as a precursor to several key neurotransmitters, including dopamine, norepinephrine, and epinephrine. These chemicals are responsible for alertness, focus, motivation, and stress resilience. Because these pathways become depleted during periods of heavy substance use and withdrawal, tyrosine plays an important role in restoring normal cognitive and emotional function.

How It Helps

In the afternoon dose, L-Tyrosine helps replenish neurotransmitters that naturally dip as the day goes on, which can trigger cravings, irritability, or mental fatigue. By supporting dopamine and norepinephrine production, it promotes clearer thinking and steadier focus during the difficult afternoon window when many people experience a motivational crash. This makes it easier to stay mentally sharp and emotionally stable as the day continues.

Supporting Studies

What It Is

L-Theanine is an amino acid naturally found in green tea that is known for promoting relaxation without sedation. It increases alpha brain wave activity, which is associated with calm focus and mental clarity. L-Theanine also influences neurotransmitters like GABA, serotonin, and dopamine, helping the brain maintain a balanced and steady state.

How It Helps

In the afternoon dose, L-Theanine helps smooth out the stress and anxiety that typically build later in the day during withdrawal. By calming the nervous system while preserving alertness, it reduces the mental tension that often triggers cravings or restlessness. This creates a more relaxed but focused state of mind, making it easier to stay steady through the afternoon.

Supporting Studies

What It Is

Ashwagandha is an adaptogenic herb that has been used for centuries to support stress resilience and hormonal balance. Adaptogens help the body maintain stability during physical and psychological stress by regulating the hypothalamic pituitary adrenal axis. Ashwagandha is especially known for its ability to lower cortisol, the primary stress hormone.

How It Helps

In the afternoon dose, Ashwagandha helps counter the spike in stress and irritability that often appears later in the day during withdrawal. By regulating cortisol, it reduces anxiety, emotional reactivity, and that wired but tired feeling that can lead to cravings. This helps promote a calmer, steadier state so the rest of the day feels more manageable.

Paying It Forward.

The first Quit Kits were packed by hand and heat-sealed in individual pouches: morning, afternoon, and nighttime doses. I labeled, packed, heat-sealed, and trimmed every pouch from a controlled work station in my home. They came with enough supply for two weeks. 

 

By the time I had sent out 50 free Quit Kits, I had packed 2100 individual pouches and spent nearly $3,000.

What I hadn't counted on was the sheer generosity of the Quit Kit community. Even though I only asked for the cost of shipping for a kit, more than 90% of people gave an additional amount. They asked that I use the extra money to pay for someone else's Quit Kit.

By the time the 50 kits had been delivered, these donations had covered over 80% of Quit Kit material costs.

Nighttime Blend

Title

  • Gamma Amino-Butyric Acid

  • L-Tryptophan

  • Melatonin

  • Magnesium Glycinate

  • Vitamin C

What It Is

GABA is the primary inhibitory neurotransmitter in the brain, responsible for slowing down neural activity and creating a sense of calm. It helps regulate anxiety, muscle tension, and the ability to transition into deeper stages of sleep. Many people in withdrawal have an overactive nervous system, which makes GABA especially important for restoring balance.

How It Helps

GABA helps quiet the overstimulated nervous system so the body can relax and prepare for sleep. It reduces restlessness, agitation, and that wired but exhausted feeling that often hits at night during withdrawal. When paired with Magnesium Glycinate in the Quit Kit, its calming effects become even stronger, making it easier to settle into deeper, restorative sleep.

Supporting Studies

What It Is

L-Tryptophan is an essential amino acid that the body uses to produce serotonin and melatonin. Serotonin supports mood stability and emotional regulation, while melatonin governs the sleep wake cycle. Because the body cannot make tryptophan on its own, it must be supplied through diet or supplementation.

How It Helps

L-Tryptophan helps replenish serotonin levels that often drop during withdrawal and contribute to low mood and emotional instability. It also boosts natural melatonin production, making it easier to fall asleep and stay asleep. This combination supports smoother mood regulation and more restorative sleep during a period when both are usually disrupted.

Supporting Studies

What It Is

Melatonin is a hormone naturally produced by the pineal gland to regulate the sleep wake cycle. Its release is tied to darkness and signals the body that it is time to wind down. Melatonin also interacts with antioxidant systems and supports overall cellular recovery during sleep.

How It Helps

Melatonin helps reset a disrupted sleep schedule and makes it easier to fall asleep during the heightened restlessness of withdrawal. By strengthening the natural sleep signal, it supports longer and more restorative sleep cycles. This deeper rest gives the brain and body the recovery window they need to stabilize mood, reduce irritability, and rebuild energy.

Supporting Studies

What It Is

Magnesium Glycinate is a highly absorbable form of magnesium bound to the amino acid glycine. Magnesium is essential for muscle relaxation, nerve function, and over 300 enzymatic reactions in the body. This form is known for its calming properties and gentle effect on the digestive system, making it ideal for nighttime support.

How It Helps

Magnesium Glycinate helps relax tense muscles, reduce physical agitation, and calm an overactive nervous system. Many people in withdrawal experience restlessness or difficulty winding down, and magnesium directly supports the systems that regulate these symptoms. When combined with GABA, it enhances overall relaxation and helps the body settle into deeper, more restorative sleep.
