Nutritional Foundation

The foundation that covers what your diet may be missing. Multivitamins fill micronutrient gaps (vitamins + active minerals), while calcium + vit D3 protect bones and muscle function, fundamental given the repetitive impact of running.

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
Multivitamin Micronutrient coverage; safety net ✅ With meal (fat for vit A/D/E/K) LE Two-Per-Day Multivitamin $18.00 R$1.55
Calcium + Vit D3 Bone health; muscle contraction; immunity (D3) ✅ With meal (carbonate requires gastric acid) Needs Vita Calcium Carbonate + D3 R$45.00 R$0.75
LE Bone Restore (Ca + Mg + D3 + Boron) $8.25 R$1.42
Iron O₂ transport (hemoglobin/myoglobin); energy; prevents anemia and fatigue ❌ Fasted + Vit C (away from calcium/coffee) Nutricost Iron 65 mg (ferrous sulfate) $13.95 R$0.31

Mitochondrial

Mitochondria are the "energy factories" of your cells: during long training, they do 99% of the work. These supplements optimize three fronts: ATP production (CoQ10, ALCAR, L-Carnitine), creation of new mitochondria (PQQ, Trans-Resveratrol) and protection against oxidative stress (R-ALA).

Endurance / Performance

Supplements with robust scientific backing to delay fatigue, preserve lean mass and improve recovery. Most require chronic use (weeks) to reach muscle saturation; a few act acutely (Bicarbonate, Citrulline pre-workout).

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
Beta-Alanine Muscle pH buffer (carnosine) Independent Nutricost Beta-Alanine (powder) $7.50 R$0.64

Sodium Bicarbonate Extracellular buffer; blood pH Light meal with carbs Nutricost Sodium Bicarbonate $9.99 R$0.86
Maurten Bicarb System $31.82 R$40.97

Race Fuel

The modern dual-fuel approach in ultras: carbohydrates as primary fuel, ketones to spare glycogen and support mental focus in the final hours. Strictly acute use, restricted to the race or key training sessions.

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
Exogenous Ketones (BHB) Brain fuel; spares glycogen Independent Ketone-IQ (HVMN) $30.00 R$25.75
Carbohydrates Primary exercise energy Maurten Drink Mix 320 $56.00 R$20.60
Maurten Drink Mix 160 $45.00 R$12.88
Maurten Gel 100 $52.00 R$22.32
Maurten Gel 160 $55.00 R$23.60

Electrolytes / Hydration

Hydration is not just water. Sodium is lost in large amounts via sweat; magnesium is a cofactor for >300 enzymes and critical for muscle contraction. In ultras, hyponatremia kills more athletes than mild dehydration. Also includes Mg L-Threonate (the only Mg form that crosses the BBB) for cognitive function and sleep.

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
Magnesium (Glycinate + B6) Cofactor for ATP and >300 enzymes After meals Magnen B6® (Marjan) R$95.00 R$3.17
Magnesium L-Threonate Only Mg that crosses the BBB; cognition and sleep Independent LE Neuro-Mag® (Magtein®) $31.51 R$5.41
Electrolytes (Na+K+Mg+Ca) Hydro-electrolyte replenishment via sweat; prevents hyponatremia Independent; with water Nutricost Electrolyte Complex $22.95 R$0.98

Anti-inflammatories

High-volume athletes live with low-to-mid systemic inflammation that hurts recovery and adaptation. Omega-3 modulates inflammatory pathways by producing resolvins and protectins, without the "off-switch" effect of NSAIDs like ibuprofen, which can blunt training adaptation.

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
Omega-3 (EPA/DHA) Reduces systemic inflammation and DOMS ✅ Fat required NOW Foods Omega-3 1000mg $7.95 R$0.41

Joints / Knee

In ultras, knees absorb 3–7× body weight at every footstrike. These supplements target three complementary pathways: oral immune tolerance (UC-II), substrate for collagen synthesis in tendons and ligaments (hydrolyzed + Vit C) and inflammatory inhibition in joints via 5-LOX (Boswellia AKBA).

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
UC-II Oral immune tolerance; cartilage ❌ Empty stomach Needs Vita Type II Collagen R$90.00 R$3.00
Hydrolyzed Collagen (Types I+II+III) + Vit C Collagen synthesis in tendons/ligaments Independent LE Collagen Peptides Skin & Joints $30.00 R$4.98
Boswellia Serrata Inhibits 5-LOX; joint stiffness ✅ Fat Nutricost Boswellia 600mg $15.95 R$0.46

Body Composition

Thermogenics and metabolic modulators to support fat loss without sacrificing lean mass. Modest effects on their own; they work as accelerators when diet + training are aligned, never replacing the underlying work.

SubstanceFunction (summary)FoodEvidenceProductPricePrice/dose
Capsaicinoids (Capsifen®) Thermogenic If sensitive stomach, with food LE Thermo Weight Control $7.50 R$0.64
Meratrim® Abdominal adiposity control ❌ Empty stomach LE Waistline Control $12.00 R$1.03

Summary by evidence level
