You have kidneys and a liver. They are the best detox machines in the universe. They function 24/7. They do not need "celery juice" to work. They need water and micronutrients.
The Danger of "Detox Diets"
Most detoxes are just starvation diets with laxatives. You lose weight (water and poop), but you strip muscle and crash your metabolism.
Fitblues promotes Sustainable Nutrition. Whole foods, fiber, and water. That is the only detox you need.
What to Track Instead
Track Fiber in Fitblues. Fiber binds to toxins in the gut and removes them. Track Water. Most people "detoxing" are just getting hydrated for the first time.
Conclusion
Don't fall for marketing. Trust anatomy. Eat real food and let your body do the rest.
