Q: Should I take Vitamin D3 liquid with or without food?A:Vitamin D3 liquid is best taken with a meal containing fat. A study published in theJournal of the Academy of Nutrition and Dietetics(Feb. 2015) found that vitamin D3 absorption increased by 32 when taken with a meal containing about 30 of calories from fat.†
Q: How do I know if I need to take supplemental vitamin D3?A:The only way to accurately assess your vitamin D status is through a blood test called 25-hydroxyvitamin D. Levels below 30 ng mL are generally considered insufficient, while levels below 20 ng mL are considered deficient. Vitamin D toxicity typically does not occur until levels reach 150 ng mL or higher.
Q: What causes Vitamin D deficiency?A:Vitamin D levels can vary widely depending on factors like season, geographic location, skin pigmentation, and sun exposure. Reduced ultraviolet (UV) light exposure, especially in winter months or in northern latitudes, can lead to lower vitamin D levels. Darker skin tones have more melanin, which can reduce UV absorption and increase the risk of deficiency. Dietary sources of vitamin D are limited but include fatty fish, cod liver oil, fortified milk, and cereals.
Q: How much Vitamin D3 do I need to take?A:Vitamin D needs vary based on age, skin tone, location, sun exposure, weight, and other factors. Cooper Clinic recommends consulting with your healthcare provider to determine the appropriate intake based on your individual blood test results and health status.
