This Spring Valley D3 supplement provides 400 IU of Vitamin D3 (Cholecalciferol), which is a very low dosage, often deemed sufficient only for infants or as a minimal daily intake. For adults, this dose is typically inadequate to address or prevent deficiency, or to provide substantial benefits for immunity, bone health, or mood. Despite its extremely low price per serving, its low potency significantly limits its overall effectiveness for comprehensive adult health goals.
thumb_upPros
Contains the highly absorbable Vitamin D3 (Cholecalciferol) form.
Offers an exceptionally low price per serving, making it very budget-friendly.
Suitable for very minimal supplementation or for infants/children requiring lower doses.
thumb_downCons
The 400 IU dosage is largely insufficient for adult needs to achieve optimal vitamin D levels or significant health benefits.
Limited impact on comprehensive health goals due to low potency.
warningWarnings
Adults seeking comprehensive health benefits from Vitamin D should consider higher dosages, typically 1000-5000 IU daily, as recommended by nutritionists.
As a Vitamin D supplement, its value is significantly limited by its very low dosage of 400 IU, making it less suitable for the comprehensive adult health goals typically associated with Vitamin D supplementation. Better value and efficacy can be found in higher-dose alternatives.
Goals
Bone Health 55.0
While Vitamin D is crucial for calcium absorption and bone health, 400 IU provides only foundational support. Most adults require a higher dose to effectively maintain bone density and support optimal skeletal strength.
General Health 50.0
The 400 IU dosage provides only minimal support for general adult health. While it can help prevent severe deficiency, it is often inadequate for optimizing overall well-being and cellular function in most adults.
Immunity 50.0
For effective immune system support and modulation, significantly higher doses of Vitamin D are typically recommended. 400 IU offers only a basic level of support and may not be sufficient to enhance immune resilience for adults.
