Description
Most people are deficient. Most don't know it.
Desk jobs, indoor training, sunscreen, and winter months all cut off your body's primary D3 source: sunlight. The result is compromised immunity, low energy, weakened bones, and mood dips that are easy to mistake for something else.
Iron & Ivory Vitamin D3 delivers 2,000 IU of cholecalciferol — the D3 form your body naturally produces from sunlight, significantly more effective at raising and maintaining blood D levels than the synthetic D2 found in cheaper supplements. It supports calcium absorption and bone mineralization,† immune system regulation,† muscle contraction efficiency and strength output,† and serotonin synthesis for energy and mood.† One softgel. 100-day supply. Year-round.
