Frequently Asked Questions
Answers to the most common questions about our recommended supplements.
Can I use more than one of these products at the same time?
CitrusBurn (daytime) and SleepLean (nighttime) are designed to complement each other and can be used simultaneously as part of a 24-hour metabolic support routine. ElectroSlim can be used alongside either product. However, always consult your healthcare provider before combining multiple supplements, especially if you take prescription medications.
Are these products safe for long-term use?
All three products are formulated with natural, non-habit-forming ingredients and are designed for consistent daily use. They do not contain synthetic stimulants, controlled substances, or habit-forming compounds. For long-term use beyond 6 months, we recommend consulting your healthcare provider for a routine check-in.
How long does it take to see results?
Most users report initial improvements within 2–4 weeks of consistent use. More significant metabolic and body composition changes are typically observed after 8–12 weeks when combined with a balanced diet and regular physical activity. Individual results vary significantly based on lifestyle, diet, and health status.
Are these products approved by the FDA?
These are dietary supplements, not pharmaceutical drugs. In the United States, dietary supplements are regulated by the FDA under DSHEA (Dietary Supplement Health and Education Act) but are not required to undergo pre-market FDA approval. All three products are manufactured in GMP-certified facilities, which ensures consistent quality and safety standards.
What is the return policy if I am not satisfied?
All three products are backed by a 60-day money-back guarantee through their respective official websites. If you are not satisfied with your results for any reason, you can request a full refund within 60 days of purchase.
