With five thousand international units of vitamin D3 in each softgel, this is the format for those who want to meet their daily needs in one dose without the hassle of taking extra pills. Life Extension uses cholecalciferol, a natural form of vitamin D3 that the body synthesizes when exposed to sunlight.
Composition and form of release
One capsule contains 125 mcg (5000 IU) of cholecalciferol. The base is unrefined extra virgin olive oil, which ensures the dissolution of the fat-soluble vitamin. Auxiliary components include medium-chain triglycerides, glycerin, gelatin, purified water and rosemary extract.
Packaging - 60 soft gelatin capsules. The product does not contain gluten, Non-GMO status is confirmed by the LE Certified certificate.
Why take vitamin D3?
Vitamin D3 is a fat-soluble vitamin that participates in several key processes at once. The first and most well-known direction is bone tissue support: D3, together with vitamin K and trace elements, promotes the delivery of calcium to the bone matrix, which is important for bone and tooth density.
The second direction is the immune system. Vitamin D3 is involved in the regulation of the immune response, which is why it is often chosen during seasons of reduced solar activity - autumn and winter.
The third is the cardiovascular system. D3 affects the balance of calcium in the body, supports the normal functioning of the vascular endothelium and helps regulate renin levels, which is associated with maintaining blood pressure within normal limits.
Cognitive function is worth mentioning separately: studies have documented a correlation between normal serum D3 levels and the preservation of cognitive abilities in adulthood. This does not replace medical care, but is an argument for regular monitoring of vitamin levels.
How much vitamin D3 should you take per day?
The manufacturer recommends one capsule per day with food - or as directed by a healthcare professional. The 5,000 IU (125 mcg) dosage is higher than the standard 2,000 or 4,000 IU, so Life Extension specifically recommends testing your 25-hydroxyvitamin D blood levels three months after starting.
The manufacturer's recommended target range is 50-80 ng/ml throughout the year. If the test results show that the level is already sufficient, the dosage is adjusted together with the doctor.
Vitamin D3 5000 IU: who is this format suitable for?
The 5000 IU format is convenient primarily for those who have received test results showing vitamin D deficiency or insufficiency and want to adjust their levels under the supervision of a doctor. It is also chosen by people who live in regions with short daylight hours or spend most of their time indoors.
For prophylaxis without prior analysis, lower dosage forms are more often suitable - 2000 or 4000 IU. The decision on dosage should be agreed with the doctor, especially with long-term use.
The combination of vitamin D3 + K2 is a common approach: vitamin K2 helps direct calcium into the bone tissue, not into the blood vessels. This product does not contain K2, so it is taken separately if necessary.
Storage and reception conditions
Store in a cool, dry place, away from direct sunlight. Take with meals - fat-soluble vitamins are better absorbed with food containing fats. Olive oil in the capsule partially solves this issue, but full intake with meals is still recommended.
