Summer and Vitamin D: Should You Adjust Your Supplements?

Should You Stop Taking Vitamin D Supplements in Summer? A doctor weighs in on the common question of whether vitamin D supplements are necessary during the summer months when sun exposure increases. According to Dr. Isabel Vina, high doses of vitamin D supplements (over 2000 IU) may be unnecessary and could even be harmful during summer due to increased sun exposure. "Dosages over 2000 IU might lead to toxicity," she explains in a recent video. However, she notes that lower doses (around 1000-2000 IU) are generally safe to continue. The increased sun exposure during summer months provides sufficient vitamin D for many individuals. This advice is particularly relevant for individuals already taking vitamin D supplements, who may want to adjust their intake based on seasonal changes in sun exposure. The video encourages viewers to consult their healthcare providers for personalized guidance.
