21-Day Anti-Inflammatory

The Food-First Philosophy

No supplement will compensate for a poor diet. The meal plan in this program is designed to deliver the vast majority of what your gut needs through whole foods. Supplements are exactly that — supplementary. They fill specific gaps, support specific situations, and can accelerate results when used alongside the dietary and lifestyle foundations.

Don't feel pressured to buy everything on this list. Start with the foundations (the program itself), and add supplements strategically based on your individual needs.

Days 1-7

Support the Reset

Phase 1 is about removing irritants and giving your digestive system a break. The supplements here help your body actually break down and absorb the clean, whole foods you're now eating.

Why It Matters for Gut Health

When you've been dealing with digestive issues, your body's own enzyme production is often compromised. As you transition to a whole-food diet, digestive enzymes help your body process food properly, reducing bloating and discomfort while improving nutrient absorption.

Key Benefits

  • Reduces bloating and heaviness after meals
  • Improves nutrient absorption from whole foods
  • Supports the transition from processed to whole foods
  • Helps with protein, fat, and carbohydrate digestion

Dosage

1 capsule per main meal

Timing

With first bites of food

Duration

Throughout program, reassess at Phase 3

What to Look For

  • Broad-spectrum formula (protease, lipase, amylase)
  • Plant-based enzyme sources
  • Minimal fillers and additives

Digestive enzymes are a bridge, not a destination. As your gut health improves, your body's own enzyme production should recover. Many people can taper off by the end of the 21 days.

Why It Matters for Gut Health

Vitamin D plays a direct role in maintaining gut barrier integrity and regulating the gut immune system. Deficiency is linked to increased intestinal permeability. Starting Day 1 ensures meaningful levels by the time you reach active gut repair in Phases 2 and 3.

Key Benefits

  • Supports gut barrier integrity
  • Regulates gut immune function
  • K2 ensures proper calcium metabolism
  • Reduces inflammation markers

Dosage

D3: 1000-4000 IU + K2: 100-200mcg

Timing

With breakfast (fat-containing meal)

Duration

Continue long-term, adjust seasonally

What to Look For

  • Combined D3 + K2 formula
  • K2 in MK-7 form (best absorbed)
  • Third-party tested for purity

If possible, get your vitamin D levels tested. Aim for blood levels of 40-60 ng/mL. Most people in northern latitudes need to supplement year-round, with higher doses in winter.

Why It Matters for Gut Health

Omega-3s reduce inflammatory signaling that damages the gut lining, support the production of healing mediators, and are associated with greater microbial diversity. Starting in Phase 1 helps reduce baseline inflammation.

Key Benefits

  • Reduces gut inflammation
  • Supports tissue healing
  • Promotes microbial diversity
  • Anti-inflammatory throughout the body

Dosage

Combined EPA + DHA: 1000mg+ daily

Timing

With meals containing fat

Duration

Continue if not eating fatty fish 3x/week

What to Look For

  • Combined EPA + DHA of at least 1000mg
  • Third-party tested for purity and heavy metals
  • Triglyceride form (better absorbed)
  • Algae-based for plant-based diets
2

Days 8-14

Repair & Reinoculate

Phase 2 is when you actively repair the gut lining and begin rebuilding microbial diversity. These supplements complement the gut-lining repair foods, fermented foods, and increased plant diversity you're introducing.

Why It Matters for Gut Health

Phase 2 is when you actively repair the gut lining and rebuild microbial diversity. Adding this multi-strain probiotic amplifies the reinoculation effect alongside fermented foods you're introducing.

Key Benefits

  • 24 clinically studied strains
  • Documented benefits for gut barrier integrity
  • Supports digestive health and micronutrient synthesis
  • Dual-capsule system protects strains through stomach

Dosage

2 capsules daily

Timing

With or without food

Duration

Ongoing daily support

What to Look For

  • Multi-strain formula with documented survivability
  • Clinically studied strains
  • Prebiotic included for strain support
Clinical Safety Warnings: When NOT to use
  • Do not take if you have a high fever, active gastrointestinal bleeding, or a severely compromised immune system.
  • If you experience severe bloating, diarrhea, or cramping, reduce the dose to 1 capsule every other day or temporarily discontinue.
  • Consult your physician before use if you are pregnant, nursing, or have a history of major bowel surgeries.

Start with 1 capsule for the first 3 days if you're sensitive to probiotics. Some mild gas or bloating in the first week is normal and typically resolves within 5-7 days.

Why It Matters for Gut Health

When glutamine is in short supply, your gut lining cells can't regenerate efficiently. Supplemental glutamine provides a direct building block for gut lining repair — the central focus of Phase 2.

Key Benefits

  • Primary fuel for gut lining cells
  • Supports gut barrier repair
  • Helpful during high stress or intense training
  • Promotes intestinal cell regeneration

Dosage

5g daily

Timing

Empty stomach, morning (in lemon water)

Duration

Phases 2-3, can continue or cycle

Optional if you're drinking 1-2 cups of bone broth daily — bone broth is naturally rich in L-glutamine along with other gut-healing amino acids.

Why It Matters for Gut Health

Unlike standard zinc supplements, zinc carnosine has a slow-release mechanism that allows it to adhere to the gut wall and deliver zinc directly where needed. Research shows it stabilizes gut mucosa and supports tight junction integrity.

Key Benefits

  • Stabilizes gut mucosa and supports repair
  • Maintains tight junction integrity
  • Protects against NSAID-induced gut damage
  • Reduces markers of gut inflammation

Dosage

75mg total (37.5mg twice daily)

Timing

With breakfast and dinner

Duration

Continue for 8-12 weeks during active repair

What to Look For

  • Zinc carnosine specifically (not regular zinc)
  • Delivers approximately 16mg elemental zinc daily
  • Well-tolerated, gentle on stomach

If continuing beyond 12 weeks, consider adding 1-2mg of copper daily, as prolonged zinc supplementation can affect copper balance.

Days 15-21

Optimize & Maintain

By Phase 3, you're taking everything from Phases 1 and 2. No new supplements are added — instead, this is when you assess what's working and start building your long-term stack.

Phase 3 Evaluation Questions

  • Are the digestive enzymes still necessary, or is your digestion handling meals well on its own?
  • How is your energy, mood, and sleep? (Magnesium may be worth adding)
  • Which supplements will you continue post-program?

Targeted Support

Situation-specific supplements that aren't part of the core protocol but can be valuable depending on your individual needs. Add these at any phase.

Why It Matters for Gut Health

Magnesium supports proper muscle contractions in the digestive tract (peristalsis), improves sleep quality and stress reduction — both critical for gut health and healing.

Key Benefits

  • Supports bowel regularity
  • Improves sleep quality
  • Reduces stress and promotes relaxation
  • Required for digestive muscle function

Dosage

200-400mg

Timing

Before bed

Duration

Most people benefit long-term

What to Look For

  • Magnesium glycinate for sleep and stress (recommended)
  • Magnesium citrate for constipation relief
  • Avoid magnesium oxide for general use (poorly absorbed)

Add this if you're struggling with sleep, constipation, or high stress levels. It's one of the safest and most beneficial supplements available.

Optional Additions

Beneficial but not essential. Consider these as your gut health stabilizes and you move into long-term maintenance.

Why It Matters for Gut Health

PHGG increases butyrate production — a key fuel for colon cells — without the gas and bloating that other fiber supplements can cause. One of the few fiber supplements with good clinical evidence specifically for IBS and gut health.

Key Benefits

  • Increases butyrate production
  • Well-tolerated even with IBS/FODMAP sensitivity
  • Supports beneficial bacteria
  • Minimal gas and bloating compared to other fibers

Dosage

Start 5g, build to 10g over 1-2 weeks

Timing

Mixed in water, any time

Duration

As needed for fiber support

Most useful if you're struggling to meet fiber targets through food alone, or if higher-FODMAP fiber sources cause symptoms.

Why It Matters for Gut Health

These amino acids support gut lining repair. Collagen peptides are a convenient alternative for people who don't enjoy or can't prepare bone broth regularly.

Key Benefits

  • Rich in gut-healing amino acids
  • Convenient alternative to bone broth
  • Easy to add to smoothies or coffee
  • Supports connective tissue throughout body

Dosage

10-15g daily

Timing

Mixed into smoothies, soups, or beverages

Duration

As replacement for bone broth

If you're already drinking bone broth daily, you're getting many of the same amino acids. Collagen peptides are most useful as a replacement for bone broth, not in addition to it.

Why It Matters for Gut Health

Curcumin has been shown to reduce gut inflammation, support gut barrier integrity, and modulate the gut microbiome. The turmeric in cooking doesn't provide therapeutic amounts.

Key Benefits

  • Potent anti-inflammatory effects
  • Supports gut barrier integrity
  • Modulates gut microbiome
  • Well-researched for digestive health

Dosage

500-1000mg bioavailable formulation

Timing

With food

Duration

During active inflammation or long-term

What to Look For

  • Contains piperine (black pepper extract) for absorption
  • Or phospholipid complex (Meriva®)
  • Standard turmeric is poorly absorbed without enhancers

A Note on Quality

Not all supplements are created equal. The supplement industry is poorly regulated, and many products contain less of the active ingredient than claimed, include unnecessary fillers, or use forms that are poorly absorbed.

What to Look For

  • Third-party testing (NSF, USP, ConsumerLab, ISURA)
  • Minimal fillers and additives
  • Bioavailable forms as specified
  • Transparent labeling
  • Clinically studied strains/doses

What to Avoid

  • Proprietary blends without individual amounts
  • Long lists of unnecessary additives
  • "Kitchen sink" formulations with 30+ ingredients
  • Extremely cheap products
