Life Extension Vitamin D3 5000 IU 60 Softgels - 3-Pak

Life Extension recommends that healthy adults supplement each day with at least 2,000 IU of vitamin D. Elderly adults may benefit from higher doses such as 5,000 IU daily up to 10,000 IU daily. The objective of taking a vitamin D supplement is to achieve an optimal 25-hydroxy vitamin D blood level of between 50-80 ng/mL. For those already obtaining 1,000-3,000 IU of vitamin D in their multinutrient formulas, this 5,000 IU potency is what many need to achieve optimal vitamin D blood levels.
