Top 5 Vitamin D3 Supplements in 2016


Update: May 26, 2019

As defined by the National Institute of Health, Vitamin D3 is, “A fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger Vitamin D synthesis. Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts.”* (NIH, p.1)

Some people may ask, what is the main difference between Vitamin D and Vitamin D3? As explained by Sandi Busch of Demand Media, “There are two different forms of Vitamin D: Vitamins D-2 and D-3. Vitamin D-2, or ergocalciferol, is the form made by mushrooms from exposure to sunlight. Vitamin D-3, which is also called cholecalciferol, is the type that’s made in your skin. Both types must be converted into the hormone calcitriol before they’re active and able to benefit your body. Vitamin D is sometimes referred to as calciferol, but it’s used as an umbrella term to include Vitamins D-2 and D-3. Even though both forms can be manufactured for supplements, Vitamin D-3 that’s made from sheep’s lanolin is more commonly used, according to the Office of Dietary Supplements.”* (Busch, p.1)

Vitamin D in any form is extremely important for the health of your bones, and the absorption rate of calcium. It is a crucial factor in making sure you have enough calcium in your body, because without Vitamin D no matter how much calcium you took in it would never be absorbed into your body properly. On top of calcium absorption, Vitamin D plays a huge role in cell growth, neuromuscular and immune function, as well as the decrease of inflammation in the body.

Vitamin D3 Overdose Warning

 There is a risk for Vitamin D overdose, as silly as it sounds the repercussions are real. As explained by Katherine Zeratsky of the Mayo Clinic, The medical name for a Vitamin D overdose is hypervitaminosis D, and while rare, it can be caused by too many supplements taken orally. The build up of calcium in your blood, which is also called hypercalcemia, can pose serious threats to your health such as nausea, poor appetite, vomiting, weakness, and kidney problems.* This condition rarely, if ever, happens from sun exposure or foods that contain Vitamin D. The average dosage per supplement per adult a day is 600 IU, and toxicity can occur if 50,000 IU of Vitamin D supplements are taken daily for several months. (Zeratsky, p.1).

While an overdose on Vitamin D is not common, it is more common to see it in people who are regularly taking supplements throughout the week. It is wise to speak with your doctor if you are interested in taking Vitamin D supplements (or any for that matter) if you are taking medication for a health condition. While it hasn’t been seen to interfere with medication, it is always better to be cautious. If you have kidney problems, diabetes, or glucose control problems always consult a doctor before taking the supplements below.

Which Vitamin D3 Supplements Work?

 With a laundry list of Vitamin D3 supplements to choose from, finding one that’s effective, safe and affordable can be difficult and confusing if you don’t know what you are looking for. While most products work to some degree, there are brands that are reputable, and definitely work better than others. These top 5 Vitamin D3 supplements below use effective ingredients, and proper dosage amounts to better service your health and vitamin D3 needs.

While most foods by nature are not prevalent in providing large amounts of Vitamin D, there are some foods more saturated than others such as salmon, tuna, and mackerel.* There are small amounts of Vitamin D2 found in mushrooms, beef, liver, cheese, and egg yolks. Be cautious as there are many different ways to get Vitamin D outside of eating foods and taking supplements, such as exposure to the sun. This can cause threats such as skin cancer, so be cautious and wear sunscreen if you are going to be out in the rays.
