Tag: Weekly vitamin d

According to a 2023 study published in *Frontiers in Nutrition*, the efficacy of intermittent vitamin D supplementation is similar to daily dosing for improving circulating levels. However, the debate over whether it is better to take vitamin D daily or weekly continues among patients and healthcare providers.

Research indicates that while daily vitamin D intake is generally safe at recommended levels, large, intermittent doses can carry health risks, especially concerning side effects of taking vitamin D once a week. The body stores this fat-soluble vitamin, so high concentrations can accumulate over time, potentially leading to adverse effects like high blood calcium (hypercalcemia). This can impact various bodily systems, emphasizing the importance of proper dosing under medical guidance.

According to the NHS, Vitamin D has a half-life of several weeks, meaning strict timing is not necessary for weekly doses. But do you have to take vitamin D at the same time every week to maintain optimal levels? The answer is more about consistency over a longer period than hitting the exact same hour and minute each week.

Over a third of U.S. adults are vitamin D deficient, necessitating supplementation for many people. The primary decision for many is determining the right frequency, with research indicating that for many, taking vitamin D everyday or every week can be equally effective in the long run. However, the optimal approach depends on individual factors like initial deficiency, adherence, and specific health conditions.
