Vitamin D is not only a fat-soluble vitamin, but also a nutrient and a hormone. Vitamin D has been linked by scientists to several positive effects.
A 2021 study published in The Nursing Clinics of North America describes the three primary sources of vitamin D as sunlight, supplements, and diet.
Despite the fact that the sun and diet are both potent sources of vitamin D, many people turn to supplements, particularly in the fall and winter when the sun is weak.
If you're considering a vitamin D supplement, it's essential to consult your doctor about the optimal dosage. However, when is the optimal time to take Vitamin D?
Despite a proven association between vitamin D and sleep quality, Healthline suggests taking the vitamin in the morning rather than before bed.
According to the source, taking vitamin D supplements in the morning makes it easier and more convenient to meet daily requirements.
In addition, vitamin D supplementation at night may inhibit melatonin production and impair sleep quality.
You can take morning supplements with breakfast. Cleveland Clinic suggests taking vitamins after meals to improve absorption.
Also, Vitamins and fat-soluble nutrients on an empty stomach can upset the GI tract, causing diarrhea, stomach pains, and nausea.
