Dr. Sten Ekberg vs Dr. Jason Fung

Organ Meats (Grass-Fed)

Nutrient-dense organ meats from grass-fed animals, including liver, heart, and kidney. Organ meats are among the most bioavailable sources of B vitamins, iron, zinc, copper, and fat-soluble vitamins A and D. Available fresh or as convenient desiccated capsules for those who prefer not to cook them.

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.

Glutathione (Liposomal)

Liposomal glutathione supplement for enhanced absorption of the body's master antioxidant. Glutathione plays a critical role in detoxification, immune support, and protecting cells from oxidative stress. Liposomal delivery bypasses digestive breakdown for greater bioavailability.

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.

Green Tea (Matcha)

High-quality matcha green tea powder rich in EGCG catechins and L-theanine. Provides calm, sustained energy while delivering powerful antioxidant and anti-inflammatory benefits. Regular green tea consumption is associated with reduced cardiovascular disease risk and improved metabolic health in population studies.

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.

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.

Turmeric / Curcumin

Turmeric extract standardized for curcumin content, a potent anti-inflammatory compound. Supports joint health, reduces chronic inflammation, and may protect against age-related cognitive decline. Best absorbed when paired with piperine (black pepper extract) or in a liposomal formulation.
