Calcium(Calcium (Form: from Dicalcium Phosphate Dihydrate))
Ingredient research · Calcium
Calcium is an essential mineral that gives bones and teeth their structure and also enables muscle contraction and nerve signaling. Supplements are most useful for filling inadequate intake and, often alongside vitamin D, can help preserve bone mineral density and support fracture prevention in some higher-risk groups.
- Supports bone-mineral-density outcomes in studied healthy children and older women.

Caffeine
Ingredient research · Caffeine
Caffeine is a stimulant that blocks adenosine signaling, reducing perceived tiredness and temporarily improving alertness, attention, and reaction time. Supplementation can also enhance endurance and some high-intensity exercise performance, though its effects on sleep and jitteriness make timing and individual sensitivity practically important.
- Supports alertness, wakefulness, and feelings of energy.
- Supports response speed on attention, vigilance, and other cognitive tasks.
- Supports exercise performance across endurance, fatigue resistance, and power-based tasks.
