The winter season is a test for immunity: short days without sun, overheated offices, Christmas hustle and bustle and waves of viruses. The Winter Immunity package combines three pillars of winter defense - a high dose of vitamin C, solar vitamin D3 with an intelligent partner K2 and zinc for a fast immune response. An ideal gift and corporate benefit for anyone who wants to get through the winter without a breakdown. Key benefits: Winter sun replacement: Vitamin D3 supplements what the body lacks from autumn to spring, and K2 (MK-7) ensures that calcium gets into the bones, not into the blood vessels. Shield against viruses: Vitamin C and zinc activate the immune system so that winter does not knock you out of gear. Antioxidant protection: Vitamin C and zinc protect cells from oxidative stress from overheated interiors and winter hustle and bustle.
