The Mustard Seed
Secret
You are not what you eat — you are what you absorb. The Bioavailability Gap is the difference between the nutrients on your plate and the nutrients that actually reach your bloodstream. Root & Reason closes that gap.
Below are the six core protocols from The Mustard Seed Secret — the science-backed "keys to the vault" that transform a simple meal into a transformational nutritional event.

Most People Absorb Only 20–30% of Their Nutrients
Between your mouth and your bloodstream lies a 30-foot gauntlet. Three main "blockers" create the Bioavailability Gap: cellular walls that lock nutrients inside plant fibre, anti-nutrient "handcuffs" that bind minerals and make them unusable, and the liver's clearance system that mistakes beneficial plant compounds for waste.
Six Keys to the Vault
The Namesake Rule
Never serve cooked cruciferous vegetables naked
Broccoli, kale, and cauliflower contain glucoraphanin and myrosinase — the two ingredients for sulforaphane. Heat destroys the enzyme. Sprinkle organic mustard seed powder on cooked cruciferous vegetables to resurrect the reaction and unlock up to 400% more bioavailable sulforaphane.
The Rule: Add mustard seed powder to cooked broccoli, kale, and cauliflower.
The Fat-Soluble Key
Stop eating naked produce
Vitamins A, D, E, and K are fat-soluble — they cannot be transported across the intestinal lining without fat. Eating a fat-free salad is nutritional self-sabotage. As little as 6–8 grams of fat (1.5 teaspoons of olive oil) triggers a massive surge in antioxidant absorption.
The Rule: Always dress colourful vegetables with extra virgin olive oil or avocado.
The Spice Multipliers
2,000% more curcumin with one pinch
Curcumin (in turmeric) has near-zero bioavailability on its own — the liver flushes it out. Piperine in black pepper inhibits this clearance pathway. The result: a 2,000% increase in bioavailability. Garlic requires 10 minutes after crushing before heat is applied, allowing allicin to form.
The Rule: Always pair turmeric with black pepper. Crush garlic 10 minutes before cooking.
The Acid Rescue
Lemon juice triples iron absorption
Spinach contains iron but is also loaded with oxalates that bind to it. Adding Vitamin C (a squeeze of lemon) changes the pH and physically breaks the bond, making the iron soluble again. One study showed adding 75mg of Vitamin C tripled non-heme iron absorption.
The Rule: Always add lemon or lime juice to sautéed greens and iron-rich salads.
The 60-Minute Rule
Coffee is stealing your minerals
Tannins in tea and caffeine in coffee are aggressive mineral blockers. Drinking coffee alongside an iron-rich meal can inhibit iron absorption by up to 80%. Give your small intestine a 60-minute head start before or after mineral-rich meals.
The Rule: No coffee or tea within 60 minutes of a mineral-rich meal.
The Gut Gatekeepers
Feed your bacteria and they will feed you
Some nutrients require gut bacteria to be metabolised into active forms. Without a healthy microbiome, even the most bioavailable meal can be met with a 'closed sign.' Focus on The Three Ps: Prebiotics (garlic, leeks, onions), Probiotics (sauerkraut, kefir), and Polyphenols (berries, dark chocolate).
The Rule: Include one prebiotic and one probiotic food daily.
