Vitamins are organic substances that are necessary for effective cell functioning, development and growth. Regardless of whether you consume vitamins from foods or in supplement form, the amount of the nutrient the body will be able to access will vary with its bioavailability, defined as the extent to which nutrients can be absorbed and utilized by the body. The relative bioavailability of a vitamin is affected by a variety of factors including the mechanics of its digestion and absorption, how the nutrient is distributed throughout the bloodstream and the efficacy with which it enters specific body tissues and fluids. Certain components in foods can also affect the bioavailability of vitamins. Compounds called oxalates, for example, bind with calcium in the digestive tract. The body will then excrete the oxalate-calcium complex, limiting the amount of calcium that can be absorbed and used in body tissues. You can estimate bioavailability either by quantifying the amount of the nutrient that is found in body tissues and fluids, or by evaluating the growth or enzyme activity that is dependent on the particular vitamin.
Because of the complexity involved in measuring bioavailability, researchers have begun developing techniques that allow for more accurate estimates of bioavailability, including liquid chromatography to differentiate between individual nutrients and tracing isotopes of a particular vitamin as it makes its way throughout the body. Vitamins A, D, E and K are fat-soluble vitamins, which require fat for absorption and are stored in the body's lipid stores. You can increase the bioavailability of these vitamins by consuming them with dietary fats such as olive and canola oils, peanut butter or cheese. Storing foods that are sensitive to light and heat in dry, cool places will also ensure that vitamins are maximally available in the body. How Much Calcium Is Absorbed at a Time?

Vitamin D3 is absolutely essential for optimal performance and health. Certified organic coconut oil is the perfect addition to Vitamin D3. Fat-soluble vitamin D is suspended within the coconut oil allowing for maximum absorption.
Vitamin D3 plays an integral role in regulating the neuromuscular and immune systems, as well as mood and sleep. It’s also a critical hormone precursor that supports new cell growth and bone formation. Our vitamin D3 has organic coconut oil added which aids absorption. 5,000 IU of D3 with 100 mg of Certified Organic Coconut Oil per softgel Coconut Oil aids the absorption of fat-soluble Vitamin D. Highly bioavailable form of natural Vitamin D (Cholecalciferol) Suggested Use: Take 1 softgel per day, preferably in the morning, or as directed by a healthcare practitioner Found in cells throughout the brain and body, Vitamin D plays an integral role in regulating the neuromuscular and immune systems [1,2], as well as mood and sleep [3]. It’s also a critical hormone precursor that supports new cell growth [4] and bone formation [5,6]. Vitamin D is essential to maintaining health and optimizing performance. Unfortunately it’s only found in a few foods and often in very small amounts.
Because of it’s vital importance and lack of dietary sources, humans evolved to be able to make Vitamin D on their own. Ultraviolet (UV-B) radiation from sunlight penetrates uncovered skin and naturally gets converted into Vitamin D. Season, time / length of day, cloud cover, smog, sunscreen, and darkness of skin all affect the amount of UV exposure and rate of Vitamin D synthesis [7]. It’s been shown that cloud cover and pollution can reduce UV energy by up to 60%, and UV-B radiation doesn’t penetrate glass so exposure to sunlight through a window does not produce Vitamin D [8]. It’s estimated that 1 billion worldwide suffer from Vitamin D deficiency or insufficiency [9]. Symptoms of inadequate levels of Vitamin D include bone pain and muscle weakness, but the symptoms can be subtle and go undetected in the initial stages. Deficiency has been associated with increased risk of autoimmune, cardiovascular, and infectious diseases [10].
