VITAMIN D3 (CHOLECALCIFEROL) IS A FAT-SOLUBLE VITAMIN THAT ACTS AS A PRO-HORMONE, ESSENTIAL FOR MAINTAINING MINERAL BALANCE AND SUPPORTING SYSTEMIC HEALTH. IT IS THE FORM NATURALLY SYNTHESIZED IN THE SKIN UPON EXPOSURE TO UVB SUNLIGHT AND IS MORE EFFECTIVE AT RAISING AND MAINTAINING BLOOD LEVELS THAN VITAMIN D2.

Top Health Benefits

Bone Density & Strength: Its Primary Role Is Regulating Calcium And Phosphorus Absorption In The Intestines. This Prevents Bone-Thinning Conditions Like Osteoporosis In Adults And Rickets In Children.

Immune System Support: D3 Modulates Both Innate And Adaptive Immunity, Enhancing The Body's Ability To Fight Viral And Bacterial Infections While Reducing Chronic Inflammation.

Muscle Function: Adequate Levels Are Critical For Muscle Contraction And Strength, Which Helps Improve Balance And Reduces The Risk Of Falls And Fractures, Particularly In The Elderly.

Mood & Mental Health: Vitamin D Receptors Are Located In Brain Regions That Regulate Mood. Supplementation May Help Reduce Symptoms Of Depression, Anxiety, And Seasonal Affective Disorder (SAD).

Cardiovascular Health: It Helps Maintain Healthy Blood Pressure By Regulating The Renin-Angiotensin System And Supporting The Health Of Blood Vessel Walls.

Metabolic Health: D3 May Improve Insulin Sensitivity And Support Glucose Metabolism, Potentially Lowering The Risk Of Type 2 Diabetes.

Dental Health: By Facilitating Mineral Absorption, It Contributes To The Proper Mineralization Of Tooth Enamel And Overall Tooth Strength.

Recommended Daily Intake

Optimal Intake Depends On Age, Sunlight Exposure, And Baseline Blood Levels:

Infants (0–12 Months): 400 IU (10 Mcg).

Children & Adults (1–70 Years): 600 IU (15 Mcg).

Deficiency Correction: Doctors May Prescribe Higher Therapeutic Doses (E.G., 2,000–5,000 IU Daily Or 50,000 IU Weekly) For A Limited Time.

Safety & Precautions

Toxicity Risk: Excess Vitamin D3 Can Lead To Hypercalcemia (Too Much Calcium In The Blood), Causing Kidney Stones, Heart Rhythm Issues, Or Nausea.

Upper Limit: For Most Adults, The Safe Daily Upper Limit Is 4,000 IU Unless Supervised By A Healthcare Provider.
