Vitamin D3 is converted to calcitriol, which binds vitamin D receptors to support calcium balance, immune signalling, and gene expression.
Caution: High intakes may increase calcium levels; consider total vitamin D from all sources and discuss testing if using long term.
Green tea catechins act as antioxidants and may influence cell signalling pathways related to cellular defence and metabolism.
Caution: Contains natural caffeine unless decaffeinated; may cause jitteriness or sleep disturbance if taken late.
Carnosine functions as an intracellular buffer and antioxidant that can help limit protein glycation and oxidative stress.
Caution: Individuals limiting beta-alanine–related tingling may prefer with food; rare sensitivity can cause mild flushing.
Resveratrol interacts with cellular stress response pathways and antioxidant defences, supporting healthy oxidative balance.
Caution: May interact with certain medicines affecting blood clotting; discontinue before planned surgery unless advised otherwise.
Blueberry anthocyanins provide antioxidant activity and may support neuronal signalling and cellular resilience to oxidative stress.
Caution: May affect those sensitive to salicylates in berries; monitor for digestive discomfort if prone.
Vitamin D3 modulates immune and cellular signalling, while polyphenols from green tea, blueberry, and resveratrol focus on antioxidant and cell-protective pathways. Carnosine adds carbonyl and glycation buffering, complementing polyphenol antioxidants to support cellular renewal processes.
