Most wellness routines fail for a boring reason: nobody tells you what to expect, so you quit before anything visible happens. The 18-day reset fixes that with a simple, honest timeline.

Days 1–6: DETOX

Broad-spectrum digestive enzymes get to work on the backlog — helping break down undigested food residue so your system can finally clear it. Most people notice less heaviness and bloating first. This phase is about subtraction, not fireworks.

Days 6–12: RESTORE

With less residue fermenting, absorption starts working again. Minerals, B-vitamins and amino acids reach your cells instead of feeding gut bacteria — this is typically when steadier energy shows up and the 3pm slump softens.

Days 12–18: REJUVENATE

Skin is the slowest tissue to respond because it renews on its own cycle. Chlorella growth factor (CGF) supports that renewal from within — in lab testing it upregulated type-I collagen gene expression 3.14×. Complexion and “lightness” are usually the last, most visible change.

Why 18 days and not 30?

The three phases follow how digestion actually recovers: clear → absorb → renew. Your personal pace depends on your digestive baseline — some feel day-one changes, some need the full cycle. Knowing which phase you’re in is what keeps you consistent.

The 18-day model is built into SPIRO Plus — one lemon chewable a day, no powders, no laxatives. Ingredient studies with citations are on The Science page.

Individual results vary with your digestive baseline. Not intended to diagnose, treat, cure or prevent any disease.
