πŸ’Š Dosage & Administration

5-15g dried berries daily (traditional) OR 100-300mg standardized extract daily. Fresh berries: 20-30g daily. Can be eaten raw, in tea, smoothies, oatmeal. For immune support: 10g daily. For eye health: 13-15g daily. Juice: 120ml daily. Safe for continuous daily use - widely consumed as food. Effects on immunity after 4-8 weeks, eye health benefits long-term.
