Although we refer to Vitamin D as a vitamin, it is really a hormone. Vitamin is something that our bodies need in little quantities from food since we are unable to produce them on our own. Best Vitamin D supplements is unique among vitamins in that it may be produced by the body when exposed to sunshine.

Vitamin D is a complicated substance that plays a role in a variety of metabolic activities in the body. Adequate vitamin D levels are essential for your cardiovascular, neurological, hormonal, defense, and repair systems, as well as other biological functions.

Unfortunately, vitamin D deficiency is widespread throughout the United States. Poor food, lack of sun exposure, and malabsorption difficulties may all contribute to low vitamin D levels. That’s why many try to complement their Vitamin D intake with the best supplements and vitamins. Here is what to look for to avoid buying the wrong product!

#1. Form

Vitamin D supplements are available in two forms: D2 (ergocalciferol) and D3 (cholecalciferol). They vary not just in chemistry but also in production. Supplementary D2 is created from yeast or fungus supplied from plants, while supplemental D3 is commonly made from lanolin sourced from animals.

#2. Additional Ingredients

Calcium and other complementing components are included in some vitamin D pills. Always read the supplement label to see what’s in it and take into account any other vitamins. Consult your doctor to be sure you’re not taking more than the advised amount.

#3. Source of Fat

Vitamin D is a fat-soluble vitamin, which means it is absorbed together with lipids in the food and stored in the body’s fatty tissue and liver. Vitamin D absorption is improved when taken with a fat source. A fat source, such as olive oil, is included in certain vitamin D capsules.

Dosage of Vitamin D

Always contact a healthcare practitioner before beginning a supplement to confirm that the supplement is appropriate for you and that you know how much to take.

Vitamin D RDA is as follows:

  • 400 IU/day for babies aged 0 to 12 months (10 mcg)
  • 600 IU per day for children and adults aged from one to seventy (15 mcg)
  • 800 IU each day for adults aged 70 and over (20 mcg)


1. What role does vitamin D play in the human body?

Answer: Calcium regulation, cell development, immunological response, bone health, and glucose metabolism are among activities that vitamin D plays a role in in the human body. Involuntary muscle contractions, including those of the heart, are mostly caused by calcium regulation. Vitamin D also collaborates with calcium to promote healthy bone formation and maintenance.

The link between vitamin D and the decrease of inflammation in the immune system has been a hot topic of research. Evidence shows that those who are deficient in vitamin D are at a greater risk of sickness and infection. Maintaining appropriate vitamin D levels has also been shown to be a beneficial strategy in the prevention of insulin-resistant illnesses such as diabetes.

2. Is there something like “too much vitamin D”?

Because vitamin D is a fat-soluble vitamin, our bodies can store it, there is a danger of vitamin D poisoning if we take too much of it. Hypercalcemia (high blood calcium levels) caused by toxic doses of vitamin D may produce symptoms such as nausea, vomiting, dehydration. Excessive vitamin D supplementation may lead to calcification (or hardening) of soft tissue, which can lead to organ failure.
