Where They Differ

These products are unique to one protocol — reflecting each expert's distinct philosophy, research focus, and priorities.

Only in Dr. Jason Fung's Protocol

Apple Cider Vinegar

Raw, unfiltered apple cider vinegar with the 'mother' culture. Research suggests it may help reduce blood sugar spikes after meals by slowing gastric emptying. Dr. Jason Fung recommends it as a fasting aid — a tablespoon or two in water can help suppress hunger and stimulate digestion when breaking a fast.

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.

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.

Magnesium (Threonate/Glycinate)

Highly bioavailable magnesium in threonate or glycinate form for superior absorption. Supports deep sleep quality, cognitive function, and nervous system relaxation. Magnesium threonate is particularly valued for its ability to cross the blood-brain barrier.

Only in Valter Longo's Protocol

Omega-3 Fish Oil (High EPA)

High-potency omega-3 fish oil supplement with elevated EPA content. Supports cardiovascular health, reduces systemic inflammation, and promotes healthy brain function and mood regulation.

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.
