Here’s how it works:

Week 1: Prepare

Ease into detox by reducing dietary triggers, stabilizing blood sugar, and supporting key elimination pathways like the liver and bowels. You'll begin light dietary changes and incorporate the DPO Detox capsules and other targeted supplements to start priming your system.

Week 2: Activate

Your body has already begun releasing toxins stored in fat tissue and organs. You'll follow a clean, anti-inflammatory meal plan with tested recipes in resources section. Continue with the targeted supplements to support detoxification and energy production.

Week 3: Eliminate

With your detox pathways open and activated, your body gets to work clearing out waste. You will start the Opti Detox shake now to enhance toxin removal and support the liver. You may notice improved digestion, lighter mood, and better sleep. This is when most participants begin to feel real transformation.

Week 4: Restore & Maintain

Support your body in rebounding and rebuilding. Nutrient-dense foods, mitochondria support, and post-detox guidance help solidify your progress and establish long-term health habits.

Why Detox?

Toxins Are Everywhere  And They’re Silently Draining Your Health.

Every day, you're exposed to thousands of chemicals that disrupt your metabolism, hormones, gut, and brain. Detoxing isn’t a luxury it’s a necessity.

From the food we eat to the air we breathe, toxins are now part of daily life. Pesticides, plastics, heavy metals, mold, preservatives, cleaning products, personal care items — these exposures add up fast. Over time, they overload your liver, gut, and lymphatic system. When your body can't keep up, symptoms begin to surface:

  • Fatigue or brain fog
  • Skin issues like acne or rashes
  • Digestive problems
  • Mood swings or anxiety
  • Hormonal imbalances
  • Trouble losing weight
  • Poor sleep
  • Low immunity

Functional medicine understands that detoxification is a natural process  but it needs support in a toxic world. That’s why this program is focused on safe, science-based strategies that support your body’s built-in detox pathways, like the liver, kidneys, skin, and gut. You were made to feel good in your body. Detox helps clear what’s standing in the way.

What Benefits Can You Expect?

Feel Lighter, Clearer, and More in Control of Your Health.

This isn’t just a cleanse. It’s a reset for your energy, mood, metabolism, and more backed by the science of functional medicine. Most people don’t realize how good their body is designed to feel until they remove what’s weighing it down.


After just 4 weeks, many participants report:

  • More Energy: Say goodbye to the 2PM crash. Clear out the toxins that are exhausting your cells and reclaim steady, all-day vitality.
  • Improved Digestion: Less bloating, gas, and discomfort. Your gut gets the support it needs to heal, balance bacteria, and move smoothly.
  • Better Sleep: Detoxing can help regulate cortisol and support natural circadian rhythms, leading to deeper, more restful sleep.
  • Clearer Skin: Your skin is one of your body’s main detox pathways. When toxins are flushed out, your complexion glows.
  • Reduced Brain Fog: Better focus, sharper thinking, and improved mood — detoxing the liver and gut supports neurotransmitter health and mental clarity.
  • Hormone Balance: Detox supports the liver’s ability to break down excess hormones and clear xenoestrogens, which is especially helpful for PMS, fertility, and weight gain.
  • Weight Loss & Metabolic Reset: Many participants lose unwanted weight, especially around the midsection, due to lowered inflammation and balanced insulin levels.
  • Motivation & Momentum: When you feel better, you’re more likely to eat better, move more, and stay on track — making this program the perfect launchpad for long-term wellness.
