Cholecalciferol in a dosage of 7000 IU (175 mcg) per capsule - this is the format chosen by Life Extension for those who want to cover the daily requirement for vitamin D3 with minimal effort. One softgel per day during meals - and the question of the "sunshine" vitamin is closed.
Composition and form of vitamin D3
The active ingredient is cholecalciferol, 175 mcg (7000 IU) per capsule. It is this form that is considered biologically active and is an analogue of vitamin D, which the body synthesizes under the influence of solar ultraviolet.
Auxiliary ingredients: unrefined extra virgin olive oil, medium chain triglycerides, gelatin, glycerin, purified water, rosemary extract. Oil serves as a base for dissolution - vitamin D3 is fat-soluble, therefore it is absorbed in the presence of fats.

Why take vitamin D3?
Vitamin D3 is involved in several key processes. First, it is involved in calcium absorption: together with vitamin K and trace elements, it promotes the delivery of calcium to the bone matrix, which is important for bone and tooth density.
Second, vitamin D3 supports normal immune function—one of its most well-studied effects. Third, Life Extension notes its role in supporting cognitive health during aging: Studies show that people with normal serum vitamin D levels perform better on cognitive tests in old age.
Separately, the manufacturer points out the support of the cardiovascular system: vitamin D3 promotes normal endothelial function and a healthy inflammatory response in blood vessels, and also affects the level of renin, a hormone involved in the regulation of blood pressure.
How much vitamin D3 should you take per day?
Life Extension recommends a daily dose of 125-200 mcg (5,000-8,000 IU) per day. One capsule of Vitamin D3 7,000 IU provides 175 mcg (7,000 IU) - the middle of the manufacturer's recommended range.
If you are already taking 25-75 mcg (1000-3000 IU) of vitamin D in a multivitamin, this should be taken into account when choosing your dosage. The manufacturer also recommends checking your blood 25-hydroxyvitamin D levels after 3 months of taking it and adjusting your dose if necessary. The guideline is 50-80 ng/ml throughout the year.
The final decision on dosage should be made with your doctor, especially if you have chronic diseases or are already taking other vitamin D supplements.
How to take
One capsule per day with a meal. The fat base in the capsule (olive oil + MCT) already provides an environment for absorption, but taking with a meal further increases the bioavailability of the fat-soluble vitamin.
Who is this format suitable for?
The 7000 IU dosage is a choice for those looking for a higher level of support than the standard 1000-2000 IU in bulk supplements. This format is typically chosen by people who live in regions with a short sunny season, are rarely outdoors, or want to reach optimal levels more quickly after a confirmed deficiency.
The softgel format with olive oil is convenient for daily use and does not require a large amount of liquid. 60 capsules in a bottle - a two-month supply when taken once a day.
