Vitamin C (Ascorbic Acid)
Vitamin C is a water-soluble vitamin that acts as a potent antioxidant, protecting cells from oxidative stress. It is primarily used to boost immune function, enhance collagen synthesis, and improve iron absorption. Key caveats include its water solubility, which limits storage in the body, necessitating regular intake.

Gastrointestinal Tolerance
Context: High doses of Vitamin C can cause gastrointestinal discomfort, including diarrhea.
Kidney Stones
Context: Excessive intake of Vitamin C may increase the risk of kidney stones in susceptible individuals.
Vitamin C supplementation was associated with a reduction in the duration of cold symptoms by approximately 8% in adults.
Supplementation with Vitamin C improved skin elasticity and reduced wrinkles, likely due to enhanced collagen synthesis.
Vitamin C significantly increased iron absorption from plant-based sources, improving iron status in deficient individuals.
Vitamin C supplementation reduced markers of oxidative stress, such as malondialdehyde, in adults exposed to oxidative stress.
Vitamin C supplementation resulted in a modest reduction in systolic blood pressure by approximately 3.7 mmHg.
High-dose intravenous Vitamin C improved plasma levels and showed trends toward reduced complications in stem cell transplant patients.

Longevity Mix (Bryan Johnson)
Bryan Johnson's Blueprint Longevity Mix is the core daily powder from his self-quantified anti-aging protocol. It combines NAD+ pathway support (CaAKG), collagen precursors (Glycine, Lysine, Vitamin C), joint protection (Glucosamine, Sodium Hyaluronate), mitochondrial support (Creatine, CoQ10-adjacent), and antioxidant defence (Glutathione, Taurine). Every ingredient is dosed at clinically relevant levels validated through continuous biomarker tracking.
Immune Support and Antioxidant Defense
Combining Sea Buckthorn with Vitamin C can enhance immune function and provide antioxidant defense. Sea Buckthorn is known for its immune-boosting and antioxidant properties, while Vitamin C supports immune health and reduces oxidative stress.
