HEALTH THRU NUTRITION - Vitamin D3 50mcg 2,000 IU - 365 SoftgelsDESCRIPTION It is estimated that over 40% of the US population has low vitamin D levels. Unfortunately, as we age, our ability to convert dietary vitamin D into its active form diminishes, as does our ability to synthesize vitamin D from sunshine, reducing our bodys vitamin D levels further. Therefore, people 50 years old and above are at an increased risk of developing vitamin D deficiency. DETAILS Package Description: 365 Softgels Serving Size: 1
