Safety Measures in Founders Fuel
Founders Fuel Safety and Quality Control Process
How Ingredients Are Sourced and Tested
Founders Fuel takes pride in sourcing its botanicals directly from their native regions. Kava comes from Fiji, cultivated by the region’s leading producer, while Kratom is sourced from trusted suppliers in Indonesia who follow ethical and sustainable harvesting methods. This ensures the raw materials are of the highest quality.
The quality control process is meticulous, involving three distinct phases. First, supplier documentation is reviewed to confirm that raw materials meet initial standards. Next, in-house testing is performed on each ingredient to verify its safety and quality. Finally, every batch of the finished product undergoes thorough testing to confirm its safety and potency. This includes screening for pesticides, harmful microbes, and heavy metals.
Kratom is further processed using a patented nano-enhancement technique to improve its bioavailability, allowing for smaller yet effective doses. Kava, on the other hand, is used in its natural root powder form to retain the synergistic effects of its compounds.
These careful sourcing practices are matched by equally rigorous manufacturing standards.
Manufacturing Process and Quality Control
The production process builds on the strict sourcing protocols with advanced techniques to ensure product safety and consistency. Manufacturing takes place in a GMP-certified facility, adhering to 21 CFR Part 111 and Part 117 regulations. Although dietary supplements are not FDA pre-approved, Founders Fuel collaborates with an FDA auditor to maintain compliance and uphold high standards.
"The manufacturing team works closely with an FDA auditor to ensure GMP compliance and maintain the highest quality standards." - Founders Fuel
Proprietary extraction methods are used to eliminate residual solvents, and a multi-stage filtration system removes impurities down to 1 micron. The formula avoids artificial colors, flavors, and additives, focusing instead on enhancing the bioavailability of natural ingredients. Every batch undergoes comprehensive testing to ensure consistent quality and safety from the raw materials to the final product.
Founders Fuel Ingredients Explained
Kava and Whole Leaf Kratom
Founders Fuel is built around two key botanicals: kava (Piper methysticum) and whole leaf kratom (Mitragyna speciosa). Kava, recognized for its calming properties, has been rated Examine Evidence Grade A for anxiety reduction when consumed in doses of 100–400 mg daily. Meanwhile, whole leaf kratom is known for its dose-dependent effects. At lower doses (less than 5 grams), it’s often used to enhance energy and productivity.
Dr. Marc T. Swogger from the University of Rochester Medical Center highlights its traditional use:
"At low doses, kratom has long been consumed orally as a stimulant to enhance stamina and productivity, making it particularly popular among field laborers working long days in arduous conditions".
Kratom’s main active compound, mitragynine, activates G-protein coupled pathways, which reduces the risk of respiratory depression compared to other substances. A 2024 study further confirmed that a liquid blend of kava and kratom was safe for short-term use in healthy adults, with no significant effects on liver or kidney function over six days.
However, caution is key. Individuals with liver disease should avoid kava, and its use should generally be limited to one or two months. For kratom, it’s essential to inform healthcare providers about its use, avoid combining it with sedatives, and ensure products meet GMP standards.
Lion's Mane Mushroom and L-theanine
In addition to kava and kratom, Founders Fuel incorporates botanicals like Lion’s Mane mushroom and L-theanine for cognitive support. Lion’s Mane is a staple in nootropic blends, valued for its potential to enhance cognitive function. Its safety is verified through advanced DNA barcoding methods, specifically ITS sequencing, which ensures species purity and screens for toxic metabolites.
L-theanine complements these ingredients, promoting mood balance, focus, and alertness without the overstimulation often associated with traditional energy boosters. Together, these components provide a balanced approach to cognitive support, blending relaxation and mental clarity.

Possible Side Effects and Safe Usage Guidelines
Even with strict quality controls in place, it’s essential to understand how to use these botanicals safely and be aware of potential side effects. Individual reactions can differ, and while kava has a history of traditional use, some users may experience indigestion, mouth numbness, drowsiness, headaches, or visual disturbances. It’s also associated with risks of liver toxicity, especially when combined with alcohol or used by people with pre-existing liver conditions. Kratom, another ingredient, can lead to dependence, seizures, and, in rare cases, severe complications. Unregulated kratom products have occasionally been found to contain harmful levels of heavy metals like lead and nickel.
Founders Fuel is not suitable for individuals under 21, pregnant or nursing individuals, or those with liver or kidney conditions. If you have cardiovascular issues, psychiatric conditions, or a history of seizures, consult your healthcare provider before use. Regular users should also work with their doctor to monitor liver enzyme levels periodically. Avoid combining Founders Fuel with alcohol, sedatives, antidepressants, or blood thinners, as these combinations can heighten risks.
For safe use, stick to half a bottle per serving and limit consumption to one bottle per day. It’s also recommended to cycle usage - three to five days on, followed by two to three days off. Stay well-hydrated and pay attention to how your body responds. If you notice palpitations, severe headaches, or any unusual symptoms, stop using the product and seek medical advice immediately.
Since many people - up to 33% - don’t inform their doctors about supplement use, make sure to discuss Founders Fuel with your healthcare provider, especially if you’re on other medications. Keep in mind that the FDA doesn’t require pre-market approval for dietary supplements, so it’s up to manufacturers to ensure their products are safe and accurately labeled.
