Goal: With Phase 2 pathways active, now maximize elimination. This is the week to block enterohepatic recirculation of estrogens, push fiber, dial in hydration, and run sauna at full cadence.
| 💊 Add: Calcium-D-glucarate | Blocks gut β-glucuronidase from reactivating already-cleared estrogens — practitioner-confirmed |
| 🌾 Max fiber | Push to 35–40 g/day (carefully ramped) |
| 💧 Hydration target | 2.5–3 L water + 1 L electrolyte mix |
| 🔥 Sauna 3–4x this week | Now at full cadence |
| 🏃 Movement | Continue Zone 2 cardio 2–3x; can add 1 light strength session |
| 📋 Tracking | Mid-protocol checkpoint; note what’s working |
You’ve reduced inbound load (Week 1). You’ve activated Phase 2 enzymes (Week 2). Now the bottleneck shifts to elimination — getting the conjugated estrogens out of the body via bile + bowel + skin without reabsorbing them.
The gut microbiome’s β-glucuronidase enzymes can deconjugate estrogens in the gut and reabsorb them, undoing the liver’s clearance work. This is the “estrobolome” effect, and it’s why fiber + calcium-D-glucarate matter so much for estrogen-driven conditions.
Sauna runs at full cadence this week because the cumulative heat acclimation effect from Weeks 1–2 (plasma volume expansion, sweat efficiency improvement) means each session now clears more.
Most US adults eat ~15 g of fiber/day. Therapeutic target for estrogen clearance is 30–40 g/day. That’s a big jump for most bodies — ramp carefully or you’ll be bloated and uncomfortable.
| Food (1 cup or 1 serving) | Approx. fiber |
|---|---|
| Cooked lentils | 16 g |
| Chickpeas | 12 g |
| Black beans | 15 g |
| Raspberries | 8 g |
| Avocado (1 whole) | 10 g |
| Brussels sprouts (cooked) | 4 g |
| Broccoli (cooked) | 5 g |
| Chia seeds (2 tbsp) | 10 g |
| Ground flaxseed (2 tbsp) | 6 g |
| Steel-cut oats (gluten-free) | 5 g |
| Sweet potato (medium) | 4 g |
| Almonds (1 oz) | 3 g |
| Pear (medium) | 6 g |
| Apple with skin | 4 g |
At 35–40 g fiber/day, you need at least 2.5 L of water or fiber becomes constipating instead of clearing. Pair every fiber boost with extra fluid.
Calcium-D-glucarate is the calcium salt of D-glucaric acid, a naturally occurring compound that the body metabolizes into D-glucaro-1,4-lactone — a direct inhibitor of bacterial β-glucuronidase.
The mechanism:
⚠️ Important: because calcium-D-glucarate also lowers the bioavailability of orally administered conjugated drugs (including some oral contraceptives), review with your prescriber if you’re on hormonal medication. This is why it’s deferred to Week 3 (gives time for the prescriber conversation).
Days 15–17:
Days 18–21:
If you’re a cycle tracker, watch for cycle-day relevance — if your cycle starts during Week 3, note pain levels vs. recent cycles. Improvement (less cramping, lighter flow, shorter duration) is one of the strongest signals the protocol is helping.
You’re now at the halfway-plus mark. Ask yourself honestly:
| Question | If yes → | If no → |
|---|---|---|
| Is my WHOOP/Garmin recovery trending green more often? | Stay the course, transition into Week 4 | Worth a practitioner conversation — what might be limiting? |
| Are symptoms (pain, fatigue, bloat) directionally better? | Yes, keep going | Honest data — protocol may not be the right fit for your specific drivers |
| Are the eliminations sustainable? | Plan Week 4 reintroductions thoughtfully | Adjust Week 4 to focus on the easier wins |
| Am I sleeping better and consistently? | Whatever you’re doing is working | Sleep is the master variable — review caffeine, alcohol if slipped, screen time, bedroom environment |
If anything is concerning, that’s the moment to message your practitioner.
Before moving to Week 4 — Integration:
If everything is in good shape, proceed to Week 4 — where you’ll start food reintroduction and plan for sustainable maintenance.
