How Much Kratom Is in Vivazen? Ingredients, Serving Size & Facts

A standard Vivazen shot (2 fl oz) contains approximately 150 mg of kratom leaf extract, though the exact mitragynine content varies by batch and is not fully disclosed on the label. Vivazen also includes several other botanical ingredients. It is legal in most U.S. states but banned in a handful. Effects typically begin within 15 to 30 minutes.

What Exactly Is Kratom and How Does It Work?

Kratom (Mitragyna speciosa) is a tropical tree native to Southeast Asia. Its leaves contain active alkaloids, primarily mitragynine and 7-hydroxymitragynine, that bind to opioid receptors in the brain.

The mechanism works like this: mitragynine hits mu-opioid receptors but acts as a partial agonist, meaning it produces less respiratory depression than classical opioids like morphine. At low doses, it tends to produce stimulant-like effects. At higher doses, the opioid-like sedation and analgesia become more pronounced. According to research published in journals like Psychopharmacology, this dose-dependent duality is what makes kratom pharmacologically unusual and difficult to classify.

The NIH’s National Institute on Drug Abuse (NIDA) notes that kratom affects the same brain receptors as opioids, which explains both its appeal and its risk profile. The science here is clearer than the marketing suggests.

How Many Milligrams of Kratom Are Actually in One Vivazen Shot?

One Vivazen 2 fl oz shot contains approximately 150 mg of kratom leaf extract per serving, based on label information available as of 2026. However, the label does not break down the mitragynine percentage within that extract.

This matters because kratom extract potency varies. A 150 mg extract at 1% mitragynine yields 1.5 mg of the primary active alkaloid. At 2%, that doubles to 3 mg. Without third-party lab data specific to the batch, consumers cannot know the exact alkaloid load they are getting.

What the label typically lists:

• Kratom leaf extract (Mitragyna speciosa): ~150 mg
• Proprietary botanical blend (valerian root, passion flower, white willow bark)
• Other inactive ingredients: water, citric acid, natural flavors, potassium sorbate

For context on how this compares to powder dosing, the kratom dosage guide explains that most users report effects starting at 2 to 5 grams of raw powder, which contains far more plant material than a concentrated extract shot.

What Ingredients Besides Kratom Are in Vivazen?

Vivazen is not a single-ingredient product. The botanical blend is designed to complement kratom’s effects.

Ingredient	Reported Role	Evidence Level
Kratom leaf extract	Primary active compound	Moderate (alkaloid research)
Valerian root	Relaxation, mild sedation	Moderate (sleep research)
Passion flower	Anxiety reduction	Limited
White willow bark	Mild analgesia	Limited
Citric acid	Preservative, pH balance	N/A

The science here: Valerian root has the most clinical backing of the secondary ingredients. Studies have found modest evidence for its sedative effects via GABA pathways. Passion flower has limited research, mostly small trials. White willow bark contains salicin, a precursor to aspirin-like compounds, but the dose in a 2 oz shot is unlikely to deliver meaningful analgesic effect on its own.

The combination is pharmacologically plausible but not clinically validated as a blend. Research gaps exist on how these botanicals interact with kratom’s alkaloids.

Is Vivazen Legal in All U.S. States?

Vivazen is not legal in all U.S. states. Kratom itself is the legal sticking point, and Vivazen’s legal status follows kratom’s status wherever you are.

As of 2026, kratom is banned at the state level in:

• Alabama
• Arkansas
• Indiana
• Rhode Island
• Vermont
• Wisconsin

Additionally, some cities and counties have local bans even in states where kratom is otherwise legal. The American Kratom Association (AKA) tracks these regulations and advocates for the Kratom Consumer Protection Act in various states.

Choose Vivazen only if you have confirmed it is legal in your jurisdiction. For state-specific details, the guide on buying kratom in Idaho and kratom’s legal status in Arizona cover how these bans work in practice.

How Does Vivazen Compare to Other Kratom Supplements?

Vivazen sits in the mid-tier of the kratom shot market. It is widely available at gas stations and convenience stores, which makes it accessible but also raises quality control questions.

Product Type	Kratom Content	Price Range	Availability
Vivazen shot (2 oz)	~150 mg extract	$6-$10	Gas stations, online
MIT45 shot (2 oz)	~300 mg extract	$12-$18	Specialty stores, online
OPMS Gold shot	Variable extract	$15-$25	Kratom shops, online
Bulk kratom powder	2-5g per dose	$0.50-$2/dose	Online vendors

Vivazen’s kratom content is lower than premium competitors like MIT45. The added botanicals differentiate it, but they also mean you are getting less pure kratom per dollar compared to buying kratom shots from dedicated vendors.

How Quickly Does a Vivazen Shot Take Effect?

Effects from a Vivazen shot typically begin within 15 to 30 minutes of consumption. Peak effects occur around 45 to 90 minutes. Duration is generally 2 to 4 hours, though this varies by individual metabolism, body weight, and tolerance.

Liquid kratom extracts absorb faster than raw powder because the alkaloids are already in solution. The stomach does not need to break down plant cell walls first. This faster onset is one reason shots are popular, but it also means the margin for overconsumption is narrower.

Taking Vivazen on an empty stomach accelerates onset. Taking it after a heavy meal can delay effects by 30 to 60 minutes.

What Are the Potential Side Effects of Taking Vivazen?

Side effects are real and documented. The FDA has issued multiple warnings about kratom safety, including a 2019 advisory linking kratom to liver injury and contamination risks.

Common side effects at standard doses:

• Nausea (especially on an empty stomach)
• Dizziness or lightheadedness
• Constipation
• Dry mouth
• Increased urination

Less common but more serious:

• Elevated heart rate
• Liver stress with prolonged use (see the kratom liver safety guide for detailed risk data)
• Withdrawal symptoms after regular use

The evidence on liver risk is worth taking seriously. Case reports in clinical literature have documented kratom-associated hepatotoxicity, though causality is sometimes complicated by multi-substance use.

Who Should Not Take Vivazen Kratom Shots?

Certain populations face meaningfully higher risk. This is not a general disclaimer; the pharmacology makes these contraindications specific.

Do not take Vivazen if you:

• Have a history of liver disease or elevated liver enzymes
• Take opioid medications (risk of additive CNS depression)
• Take MAOIs or certain antidepressants (interaction risk)
• Are pregnant or breastfeeding
• Have a history of substance use disorder
• Are under 18 (and in many states, under 21)

People with heart arrhythmias should also exercise caution. Mitragynine has shown some cardiac effects in pharmacological studies, though human clinical data is limited.

For age-related purchasing rules, the kratom age limits by state guide breaks down where 18 vs. 21 rules apply.

Are There Any Risks of Addiction and Tolerance With Vivazen?

Yes. Tolerance and dependence are documented risks with any kratom product, including Vivazen. Because mitragynine acts on opioid receptors, the brain adapts to regular stimulation the same way it does with other opioid-class substances.

What the research shows: Studies found that regular kratom users report withdrawal symptoms including muscle aches, irritability, insomnia, and cravings when they stop. A 2019 survey published in Drug and Alcohol Dependence found that a significant portion of daily kratom users met criteria for kratom use disorder.

Tolerance builds faster with:

• Daily use (versus occasional use)
• Higher doses per session
• Concentrated extracts versus raw powder

The practical advice: limit Vivazen to no more than 2 to 3 times per week. Rotating with lower-potency formats can slow tolerance development. If you find yourself needing more to feel the same effect, that is a reliable signal to reduce or stop.

How Much Does a Vivazen Shot Cost Compared to Other Brands?

A single Vivazen shot retails for approximately $6 to $10 at gas stations and convenience stores. Online pricing is sometimes lower, around $5 to $7 per unit when bought in packs.

By comparison, buying kratom powder from a reputable online vendor costs roughly $0.50 to $2 per equivalent dose, making it significantly more economical for regular users. The convenience premium with Vivazen is real.

What Natural Alternatives Exist to Vivazen?

Several botanical options are used for similar purposes, though the evidence base varies considerably.

• Kava (Piper methysticum): Well-studied for anxiety reduction. Acts on GABA receptors. Less addiction risk than kratom.
• Valerian root standalone: Available in higher doses than what Vivazen provides. Moderate evidence for relaxation.
• Magnesium glycinate: Limited research for pain, but solid data for muscle relaxation and sleep.
• CBD products: Widely available, legal in most states, and have a growing evidence base for anxiety and pain.

None of these replicate kratom’s opioid receptor activity exactly. If the goal is opioid-like analgesia, the alternatives are pharmacologically different. If the goal is general relaxation, kava and valerian have cleaner safety profiles.

Common Mistakes People Make When Using Kratom Supplements

Stacking multiple shots: Taking two Vivazen shots at once significantly increases side effect risk without proportionally increasing benefit. The dose-response curve for kratom is not linear.

Mixing with alcohol: Both kratom and alcohol are CNS depressants. Combining them increases sedation risk and puts extra load on the liver.

Ignoring tolerance signals: Using Vivazen daily and gradually increasing intake is how dependence develops. Most experienced users recommend a "less is more" approach.

Buying without checking legality: Kratom's legal status varies by city and county, not just state. Always verify local rules before purchasing.

Expecting consistent potency: Gas station kratom products, including Vivazen, are not always third-party tested for alkaloid content. Batch-to-batch variation is real. The kratom brands to avoid guide covers red flags to watch for on labels.

Conclusion

The science on Vivazen is clearer than most marketing suggests. One shot delivers roughly 150 mg of kratom leaf extract alongside valerian root, passion flower, and white willow bark. The exact mitragynine content is not disclosed, which is a real limitation for anyone trying to manage their dose responsibly.

Research gaps remain on long-term kratom safety and on how Vivazen's botanical blend interacts pharmacologically. What we know is enough to use it cautiously. What we do not know is enough reason to avoid daily reliance on it.
