Description

VITAMIN D3 2,000 IU

Vitamin D3 is a fat-soluble vitamin that supports the growth and development of bones and teeth. It also plays an essential role in the functioning of the muscles and boosting energy levels in the body.

The body naturally produces Vitamin D when exposed to sunlight, and you can also receive Vitamin D from some foods like oily fish. In the winter months, especially in colder regions, the body doesn’t produce as much Vitamin D, leading to ‘seasonal depression.’*

Ingredients: Vitamin D3 (as cholecalciferol), Softgel (gelatin, glycerin, water), soybean oil, corn oil.

Manufacturer Country: USA

Product Amount: 100 softgels

Gross Weight: 1.6 oz / 0.1 lb / 45g

Suggested Use: As a dietary supplement, adults take one (1) softgel capsule daily or as directed by a health care professional.

Warning: Keep out of reach of children. Do not use if the safety seal is damaged or missing. Store in a cool, dry place and away from direct light.

Benefits of Vitamin D3 2,000 IU

Increases energy levels

Vitamin D supports mitochondria in the cells, which are responsible for energy.

Vitamin D as a seasonal support

Vitamin D3 may contribute to promoting positive mood, and there is preliminary evidence suggesting a potential reduction in negative mood associated with seasonal changes.

Improves bone density

Vitamin D has been shown to stimulate osteoblasts and improve bone density in humans.

Boosts the immune system

Vitamin D regulates the absorption of calcium and phosphorous for a better immune response.

Science Facts

Vitamin D for Cholesterol

Vitamin D supplementation may be useful in hypercholesterolemia patients with vitamin D insufficiency who are at high risk of cardiovascular diseases.

Vitamin D for Infections

A study showed that vitamin D supplementation was safe and protected against acute respiratory tract infection overall. Patients who were very vitamin D deficient, and those not receiving bolus doses experienced the most benefit.

Source

Vitamin D for Mood

Results of a self-report measure showed that vitamin D3 significantly enhanced positive affect and there was some evidence of a reduction in negative affect when dealing with seasonality.

Vitamin D for Blood Pressure

Observational studies report higher blood pressure (BP) among individuals with lower 25-hydroxyvitamin D concentration.

Vitamin D and Calcium for the Prevention of Fracture: Systematic Review and Meta-Analysis

This high-impact systematic review and meta-analysis covering 11 RCTs (34,243 participants for vitamin D alone) and 6 RCTs (49,282 participants for vitamin D + calcium) found an important distinction: vitamin D supplementation alone showed no significant association with reduced fracture risk at standard doses. However, combined daily supplementation of vitamin D and calcium was associated with a 16% reduced risk of hip fracture. This is a critical nuance — vitamin D needs calcium co-factors to deliver meaningful bone protection, and it highlights why the pairing with vitamin K2 (which directs calcium into bone) in this supplement is scientifically rational.

Combined Exercise + Vitamin D3 for Musculoskeletal Recovery

This systematic review of 7 RCTs (792 older adults) assessed the combined effect of resistance exercise training and vitamin D3 supplementation on musculoskeletal health. Meta-analysis found a large, significant improvement in lower limb muscle strength in the group combining exercise with vitamin D3 (p<0.00001), with additional significant benefits in physical performance (SPPB score), timed-up-and-go speed, and femoral neck bone density in groups using the combination approach. The review concludes that vitamin D3 supplementation provides tentative additive benefit to exercise training for muscle strength — which directly supports its use as a post-workout recovery supplement.

Menaquinone-4 Supplementation, Coronary Artery Calcification, and Arterial Stiffness

This clinical study in 26 patients investigated whether vitamin K2 (MK-4 form at 45 mg/day) could reduce coronary artery calcification and arterial stiffness. While coronary calcification continued to increase (as is typical in patients with pre-existing calcification), arterial stiffness (brachial-ankle pulse wave velocity) was significantly reduced in patients with the highest baseline vitamin K insufficiency. This finding illustrates the mechanistic synergy with vitamin D3: vitamin D increases calcium absorption, while K2 (via carboxylation of matrix Gla protein) actively inhibits calcium deposition in soft tissues like arteries — directing it toward bone instead. This "calcium routing" effect is the main scientific rationale for combining D3 and K2.
