The maximum amount of vitamin D3 ensured in a single dose is 10,000 IU, a very high concentration, suitable for those with severe deficiencies in this nutrient.

1) Vitamin D3 Quick Facts
Vitamin D3 is based on the beneficial properties of vitamin D3.
This is one of the two bio-available forms of vitamin D. However, vitamin D3 is the one that our bodies naturally produce in response to sun exposure. This form is also found in foods like fish, cod liver oil, fortified cereals and eggs. However, food sources are rather limited and without proper sun exposure (especially during cold seasons), a deficiency in this nutrient can easily install. Such an imbalance may lead to various health concerns including low bone density (that increases the risk of fracture particularly in the elderly), low immunity, poor hair growth, and increased risk of cancer.
This nutrient is oil soluble, which has led to the conclusion that a rich diet in fats may increase its absorption. However, existing research has shown that it is rather large meals that promote increased absorption rates of supplemental vitamin D, than oil based foods. Side effects have been associated mostly with ingesting excessive amounts and include: nausea, weakness, headache loss of appetite and weight loss, metallic taste and dry mouth. Doses larger than 4,000 IU per day taken for longer periods may increase Calcium levels in the blood which could lead to serious long-term damage. Vitamin D supplements were also shown to interact with other medication, including some antacids that contain Aluminum, Calcipotriene, Digoxin (Lanoxin), Verapamil, and water pills also known as Thiazide diuretics.
The recommended doses vary widely according to the specific needs of the user. However, in case of healthy individuals, the recommended daily allowances are 400 -600 IU for children under 18 years old, 600 IU for adults up to 70 years old and 800IU for adults over the age of 70.
2) Vitamin D3 Ingredients
Vitamin D3 contains the following ingredients: Vitamin D3 (from Lanolin – as Cholecalciferol), pure cold preserved oil, gelatin, glycerin, and water.
3) What Does Vitamin D3 Do?
Vitamin D3 is based on a single active substance and includes one of the two active forms of vitamin D, namely Cholecalciferol. This substance can be obtained from two sources: sunlight or food. Food sources containing a significant amount of this nutrient are limited (fish, fish oils, and eggs). Sunlight is also an unreliable source, particularly in the cold season when sun exposure decreases considerably. This makes vitamin D supplementation essential for preventing a deficiency. The substance is as important for children as it is for adults. In children, it is needed for healthy teeth, bone growth, bone formation, and prevention of specific affections affecting these structures (rickets). In adults, vitamin D3 is responsible for maintaining healthy calcium and phosphorus levels and offers protection against common diseases: muscle weakness, various types of cancers, rheumatoid arthritis and osteoporosis.
The side effects usually associated with supplemental intake are numerous and include dry mouth, metallic taste, irregular heartbeat, bone pain, weight and height loss, nausea, constipation, increased thirst, or allergic reactions. Immediate cessation and specialized help are highly advised. The daily recommended doses vary with age (children, adults, and the elderly), and the purpose of the supplementation (deficiency, cardiovascular disease, cognition, diabetes, fracture prevention, etc.). A lot of controversy regarding these daily values has arisen in the late years, due to improper dieting and increased use of sun blocking protection creams (which also reduces absorption of Cholecalciferol). Many specialists have started recommending higher doses particularly for the prevention of health conditions.
