Vitamin D is vital to healthy bones, strong immune system functions and mental/emotional wellness. Sunlight helps our bodies produce vitamin D, but our production capacity is limited... especially in winter months when sun exposure is reduced. The current RDA for vitamin D is between 200 IU and 600 IU for the average person based on age, weight and health status. But most experts now recommend that healthy individuals take in up to 1,000 IU on top of what they might get through diet and multivitamins. Those in Northern climates or with greater needs may need even more. HerbalBioTechs's new 5,000 IU vitamin D-3 softgels answer the need for those who require higher intake.
