4/5 Evidence Score

Aqua-D3® is a water-dispersible form of vitamin D3 (cholecalciferol), designed to mix easily into liquids and improve uptake of this fat-soluble vitamin. Vitamin D is essential for bone health, immune function, and overall wellness, and many people fall short of optimal levels.

Studied Dose Commonly 1000 to 4000 IU per day.
Active Compound Vitamin D3 (cholecalciferol) in a water-dispersible form.

Benefits

Immune support

A large meta-analysis found vitamin D supplementation reduced the risk of acute respiratory infections, especially in people who were deficient.

Bone health

Vitamin D is required to absorb calcium and maintain strong bones; deficiency contributes to bone loss and fractures.

Whole-body wellness

Vitamin D receptors are found throughout the body, and adequate levels support muscle, mood, and metabolic health.

Mechanism of action

1

Calcium absorption

Vitamin D enables the gut to absorb calcium and phosphorus, the minerals needed to build and maintain bone.

2

Immune modulation

Vitamin D supports both the innate and adaptive immune systems, helping the body respond appropriately to infection.

Clinical trials

Systematic review and meta-analysis of individual participant data on vitamin D for preventing acute respiratory infections. (Martineau et al. 2017, BMJ)

Adults and children across many trials.

Vitamin D supplementation reduced the risk of acute respiratory infections, with the greatest benefit in deficient individuals.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated at recommended doses.
Very high doses over time can cause high calcium; do not exceed recommended intake without testing.
Have your vitamin D level checked to guide dosing.

Important Drug interactions

Thiazide diuretics — combined with vitamin D may raise calcium; monitor.
Certain heart medications (digoxin) — monitor with high-dose vitamin D.
Tell your doctor about all medications and your vitamin D level.
