How much vitamin D3 did most heart attack survivors need to reach the target blood level?

Over half of the participants in the study required a high daily dose of 5,000 international units (IU) of vitamin D3 to reach the target blood level of 40-80 ng/mL, well above the standard 600-800 IU recommendation.

How did the Intermountain Health researchers tailor the vitamin D3 dosage for each participant?

The researchers measured each participant's vitamin D blood levels at enrollment and then adjusted their supplement dose every three months to achieve and maintain the target blood level range.

Vitamin D Breakthrough: Heart Attack Survivors Cut Risk of Repeat Attack by 52%

According to a groundbreaking new study conducted by researchers at Intermountain Health in Salt Lake City, heart attack survivors who had their vitamin D levels closely monitored and optimized with personalized vitamin D3 supplements saw their risk of a subsequent heart attack cut by 52%.

The study, which followed over 600 heart attack survivors for an average of four years, found that the majority (85%) had insufficient vitamin D levels at the start. To reach the target blood level of 40-80 ng/mL, over half of the participants required a high daily dose of 5,000 international units (IU) of vitamin D3 - well above the standard 600-800 IU recommendation.
