Quality & Manufacturing Standards
DeenFuel supplements are made in the USA in GMP-certified facilities, halal certified by independent certifiers, gelatin-free, and labeled in full. This page lists the specific standards behind those statements.
Manufacturing
- Made in the USA. Our gummies, capsules and tablets are manufactured in the United States for DeenFuel, LLC, Owings Mills, Maryland. The Made in USA mark is printed on each label.
- GMP-certified facilities. Production follows the US FDA's Current Good Manufacturing Practice rule for dietary supplements (21 CFR Part 111). The rule requires the manufacturer to set specifications for the identity, purity, strength and composition of each product, to verify them by testing or examination, and to document every batch. The GMP Certified seal is printed on our labels.
- Halal certified. Gummies, capsules and tablets carry the Islamic Services of America (ISA) mark; Fasting Fuel carries the American Halal Foundation (AHF) mark. See Halal Certification.
- Tamper-evident packaging. Every bottle ships with a safety seal. Do not use if the seal is damaged or missing.
Formulation standards
- Gelatin-free. Gummies are set with fruit pectin. Capsules are vegetable cellulose or hypromellose. Vitamin D3 with K2 is a chewable tablet. No pork-derived ingredients anywhere in the range.
- No artificial colors or flavors in our gummies. Colors come from fruit and vegetable juice concentrates, purple or black carrot extract, and beta-carotene. Flavors are natural flavors.
- Named nutrient forms. Every label states the chemical form of each nutrient (for example, vitamin D as cholecalciferol, zinc as zinc citrate, magnesium as magnesium bisglycinate chelate), so you can see exactly what you are taking.
- Branded, specified ingredients where it matters. zümXR® extended-release caffeine and Rhodiola rosea standardised to 3% rosavins in Fasting Fuel; Quatrefolic® methylfolate, methylcobalamin B12, Nigellin® Onyx black seed extract standardised to 20% thymoquinone, and curcumin 95% in Golden Years.
- Full label disclosure. The complete Supplement Facts panel and Other ingredients are published on every product page and on Ingredients & Sourcing.
