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 body’s vitamin D levels further.

Therefore, people 50 years old and above are at an increased risk of developing vitamin D deficiency.  

A simple blood test can determine your vitamin D level (a result of 20 ng/mL to 50ng/mL is considered adequate for healthy people) and can help you select the right supplement dosage along with a discussion with your doctor.  Health Thru Nutrition offers pure vitamin D-3, as cholecalciferol, in four different strengths, 1000IU, 2000IU, 5000IU, and 10,000IU, the most potent available.  

Health Thru Nutrition manufactures its Vitamin D-3 under strict cGMP standards in the USA.  All strengths are non-GMO, contain no artificial sweeteners or preservatives, are free of soy and gluten, and contain no major allergens.
