Frank Suarez vs Dr. Jason Fung

Potassium Supplement

Potassium is an essential electrolyte mineral critical for heart rhythm, muscle contraction, and nerve signaling. Most adults fall short of the recommended 4,700 mg daily intake, making supplementation a practical strategy alongside potassium-rich foods like avocados, sweet potatoes, and leafy greens.

Vitamin D3 (5000 IU)

High-potency vitamin D3 supplement providing 5000 IU per serving to support optimal blood levels. Essential for immune function, bone health, and mood regulation. One of the most widely recommended supplements among longevity researchers due to widespread deficiency.

CoQ10 (Coenzyme Q10)

Coenzyme Q10 is a naturally occurring antioxidant that plays a critical role in mitochondrial energy production. CoQ10 levels decline with age, making supplementation increasingly relevant for supporting cardiovascular health, cellular energy, and overall vitality. The ubiquinol form offers superior bioavailability compared to ubiquinone.

Probiotics (Multi-Strain)

Multi-strain probiotic supplement containing diverse beneficial bacteria to support gut microbiome health. A balanced gut microbiome is linked to improved digestion, immune function, and mental well-being. Look for formulas with clinically studied strains and high CFU counts.

Virgin Coconut Oil

Virgin coconut oil is rich in medium-chain triglycerides, particularly lauric acid, which supports energy metabolism and has antimicrobial properties. It is used in functional nutrition as a cooking fat that resists oxidation at high temperatures and as a source of readily available energy that does not require bile for digestion.

Black Coffee

High-quality black coffee, one of the most widely recommended beverages during intermittent fasting. Contains caffeine and chlorogenic acid, which may increase metabolic rate and fat oxidation. Dr. Jason Fung considers black coffee an excellent fasting companion — it suppresses appetite, does not stimulate insulin, and may enhance the metabolic benefits of fasting.

Bone Broth

Nutrient-dense broth made by simmering animal bones for extended periods. Rich in collagen, glycine, and minerals. Frequently recommended by Dr. Jason Fung as one of the best fasting aids — it provides electrolytes and a small amount of protein to ease hunger during extended fasts without significantly raising insulin.

Electrolyte Mix

Balanced electrolyte mix containing sodium, potassium, and magnesium to support hydration and cellular function. Essential for maintaining energy levels, muscle function, and cognitive performance, especially during fasting or exercise. Sugar-free formulas are preferred in longevity protocols.

Chia Seeds

Organic chia seeds rich in soluble fiber, omega-3 fatty acids, and plant protein. When soaked in liquid they form a filling gel that expands in the stomach. Dr. Jason Fung recommends chia seeds as a fasting variation — their high fiber content helps manage hunger during fasts with minimal insulin stimulation.

Pasture-Raised Eggs

Pasture-raised eggs are a nutrient-dense whole food providing complete protein, healthy fats, choline, and fat-soluble vitamins. Among protein sources, eggs produce one of the lowest insulin responses — making them a preferred choice in Dr. Jason Fung's protocol for meals that support metabolic health and stable blood sugar.

Wild-Caught Salmon

Wild-caught salmon is one of the best whole-food sources of omega-3 fatty acids EPA and DHA. Rich in high-quality protein, astaxanthin, and vitamin D, it supports cardiovascular and brain health. Consuming fatty fish 2-3 times per week is a cornerstone recommendation across longevity protocols.

Ceylon Cinnamon

Ceylon cinnamon, known as 'true cinnamon,' is a spice with research-supported blood sugar lowering properties. It may improve insulin sensitivity and help reduce fasting glucose levels. Dr. Jason Fung recommends cinnamon as a natural way to manage hunger during fasts — it adds flavor to beverages without stimulating insulin and may have protective metabolic effects.
