WHY VITAMIN D
Small nutrient. Fundamental biology.
Vitamin D helps regulate calcium and phosphate availability—minerals involved in normal bone mineralization and other physiological processes.
DOSE IN CONTEXT
Enough needs context.
1,000 IU is our daily serving—not a universal requirement.
Vitaria daily serving
Not a target
U.S. dietary reference values: National Academies / NIH Office of Dietary Supplements.
Individual needs vary with age, vitamin D status, intake, health context and clinical guidance.
VITAMIN D STATUS
Your level is shaped by more than your supplement.
ENVIRONMENT
- UVB exposure
- Season / latitude
- Time outdoors
INDIVIDUAL
- Age
- Skin pigmentation
- Body composition
INTAKE & ABSORPTION
- Dietary intake
- Supplemental intake
- Absorption and relevant health factors
Vitamin D status reflects context—not one variable in isolation.
WHAT THE EVIDENCE SUPPORTS
A role isn’t the same as a result.
Vitamin D has a physiological role.
Vitamin D contributes to calcium and phosphate homeostasis and normal physiological processes.
Supplementation changes intake.
Supplementation provides vitamin D when endogenous production and dietary intake are insufficient.
More does not automatically mean more benefit.
A nutrient having an essential biological role does not mean progressively larger supplemental doses produce progressively greater health outcomes.
THE FORM
Why cholecalciferol?
This product supplies vitamin D as cholecalciferol in a softgel containing soybean oil.
A COMMON QUESTION
Does vitamin D need K2?
Not automatically.
Vitamin K participates in the activation of proteins involved in bone and vascular biology. That provides a plausible biological rationale for pairing the nutrients, but current evidence does not establish that vitamin K2 is required for vitamin D3 to raise vitamin D status.
HOW TO TAKE
One softgel. Once a day.
Take 1 softgel daily with food, preferably with a meal containing some fat.
Vitamin D is fat-soluble. Taking D3 with a meal containing some fat can enhance absorption, so taking your softgel with food is a practical routine.
Maintenance isn’t treatment.
The Vitaria serving is intended for routine daily supplementation. Treatment of a diagnosed vitamin D deficiency may involve a different dose or regimen under healthcare supervision.
SAFETY & DOSE CONTEXT
More isn’t necessarily better.
The upper intake level is a safety boundary for long-term daily intake—not a recommended intake target.
Higher supplemental intake does not automatically produce greater health benefits.
Speak with a healthcare professional if you have relevant medical conditions, take medications that may interact with vitamin D or calcium metabolism, are pregnant or breastfeeding, or are considering higher-dose supplementation or treatment.

FAQ
A little more clarity.
1,000 IU is Vitaria’s daily serving, not a universal requirement. Vitamin D needs vary with factors including age, vitamin D status, intake and health context.
Testing may be useful when deficiency is suspected or when a healthcare professional considers it clinically relevant; whether testing is appropriate depends on individual circumstances.
Vitamin D is fat-soluble. Taking D3 with a meal containing some fat can enhance absorption, so taking your softgel with food is a practical routine.
Not automatically. K2 has a plausible biological relationship with vitamin D, but current evidence does not establish that K2 is required for D3 to raise vitamin D status.
Vitamin D3 is commonly used as a daily supplement. The appropriate intake depends on individual circumstances and total vitamin D intake from other sources.
D2 is ergocalciferol and D3 is cholecalciferol. This Vitaria product provides vitamin D as D3.
Yes. More is not necessarily better. For adults, 4,000 IU (100 mcg) per day is the U.S. tolerable upper intake level for total daily intake. It is a safety boundary, not a recommended daily target.
Treatment of diagnosed deficiency may require a different dose or regimen from routine supplementation and should be guided by an appropriate healthcare professional.
