Milk and water are among the most effective sources of vitamin D, according to a recent study that was presented at the 24th European Congress of Endocrinology in Milan. Immunological reaction to COVID-19 is just one of many health issues that have been attributed to insufficient vitamin D levels. Knowing whether or not vitamin D pills will be absorbed, and how to maximise absorption, is crucial.

People are starting to take notice of vitamin D and the part it plays in maintaining good health. Bone health is just one of many biological processes that vitamin D influences. Low vitamin D levels have also been linked to an increased risk of developing autoimmune illnesses. Not enough people are getting their recommended daily allowance of vitamin D. Experts are still arguing what goal levels should be, making it difficult to determine how many people are deficient.

Juice consumption resulted in much lower D3 levels than milk and water consumption. We couldn’t tell the difference between milk and water. Vitamin D fortification in water and milk was found to be more effective than in juice, according to the study. According to the study, milk and water are both great ways to increase your vitamin D intake, but there are plenty of other options as well.

Hens grown on pasture, free to roam in the sunshine, lay eggs with three to four times the levels of chickens raised in a confined environment. Additionally, the yolks of eggs laid by hens fed vitamin D-enriched diets can contain as much as 34,815 IU of vitamin D per 100 grammes of yolk.

Exposure to UV radiation makes some varieties of wild mushrooms very high-quality sources of vitamin D2. Mushrooms cultivated for sale sometimes lack vitamin D2 since they are cultivated in the shadows. Ultraviolet (UV) radiation is being used to increase the vitamin D content of some mushrooms.
