insights Analysis
Spring Valley Cod Liver Oil Plus Vitamins A & D3 is a cost-effective supplement that leverages the historical benefits of cod liver oil, naturally rich in Vitamin A, Vitamin D, and Omega-3 fatty acids. While it's a budget-friendly option and provides these essential nutrients, the dosage of Vitamin D3 at 135 IU is quite modest, falling short of the higher amounts typically recommended by nutritionists and public health guidelines for adults to optimize Vitamin D status. The Vitamin A content (Retinyl Palmitate) is in a bioavailable form, but its concentration relative to the low Vitamin D dose means users must be cautious about combined Vitamin A intake from other sources to avoid potential hypervitaminosis A. Online reviews often praise its affordability and ease of use as softgels, though some express concern over the low Vitamin D potency.
- Very economical price per serving, making it accessible.
- Provides natural source vitamins A and D from traditional cod liver oil.
- Convenient softgel form for easy consumption.
- Contains a significantly low Vitamin D3 dosage (135 IU) which is often insufficient for adult daily requirements or addressing deficiencies.
- The specific Omega-3 fatty acid content (EPA/DHA) from cod liver oil is not declared, limiting assessment of its anti-inflammatory benefits.
- Potential for Vitamin A overload if taken in high doses or with other Vitamin A supplements, due to the Vitamin A to D ratio.
- Do not exceed the recommended dosage, particularly if consuming other supplements or foods rich in Vitamin A, to avoid potential toxicity.
- The Vitamin D dose may be inadequate for individuals with Vitamin D deficiency or those aiming for optimal Vitamin D levels.

bolt Effectiveness for goals
Vitamin D is highly effective in promoting bone health by aiding the body in absorbing calcium and phosphate. It plays a crucial role in bone mineralization and remodeling. Sufficient levels help maintain bone density and reduce the risk of fractures.
Vitamin A is essential and highly effective for maintaining healthy vision, particularly in low light conditions. It is a key component of rhodopsin, a protein in the eye that absorbs light. Adequate intake supports normal vision and eye function.
Yes, Vitamin D is recognized for its role in modulating the immune system. It can influence both innate and adaptive immune responses. Maintaining adequate Vitamin D levels may contribute to overall immune health.
Vitamin D3 (cholecalciferol) is generally considered more effective at raising and maintaining circulating 25(OH)D levels in the body than Vitamin D2 (ergocalciferol). Both forms are metabolized by the liver into 25(OH)D, but D3 typically results in a more sustained increase. Many supplements use Vitamin D3 due to its higher potency.
Vitamin A, particularly in its retinoid forms, is widely recognized for its effectiveness in supporting skin health. It promotes healthy cell turnover and maintains the integrity of skin cells. Both dietary intake and topical applications contribute to skin maintenance.
schedule Dosage, timing & forms
For most healthy adults, a common recommended daily dosage for Vitamin D supplements ranges from 600-800 International Units (IU), though some experts suggest higher amounts. Specific needs can vary based on age, sun exposure, and existing deficiencies. It is often measured in IU, representing the biological activity of the vitamin.
Vitamin D is a fat-soluble vitamin, so it is generally recommended to take it with a meal containing some fat to enhance absorption. There is no specific time of day (morning or evening) that is definitively superior. Consistency in taking it regularly is more important than the exact time.
The two most common forms of Vitamin D found in supplements are Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D3 is generally considered more effective at raising and maintaining Vitamin D levels in the body. Both forms are available in various formats such as capsules, softgels, drops, and chewables.
Yes, dosage recommendations for Vitamin D can vary significantly based on individual needs and health status. Older adults may require higher doses due to decreased skin synthesis and absorption efficiency. Individuals diagnosed with a Vitamin D deficiency typically require higher, physician-prescribed dosages to restore optimal levels.
Yes, Vitamin D and Vitamin A supplements can generally be taken at the same time, as they are both fat-soluble vitamins and their absorption mechanisms can coexist. Some research suggests they may even work synergistically in the body. However, it is always important to adhere to recommended dosages for each to avoid excessive intake.
health_and_safety Safety & interactions
Yes, very high doses of Vitamin D can lead to hypervitaminosis D, primarily causing hypercalcemia (high blood calcium levels). Symptoms of hypercalcemia include nausea, vomiting, weakness, frequent urination, and in severe cases, kidney problems and heart arrhythmias. This condition is usually due to excessive supplementation, not sun exposure or dietary intake.
Excessive intake of preformed Vitamin A can lead to hypervitaminosis A, characterized by symptoms such as headache, blurred vision, nausea, and in severe cases, liver damage and bone abnormalities. These risks are typically associated with very high supplemental doses, not dietary intake from food. Pregnant individuals should be particularly cautious due to potential teratogenicity.
Several medications can interact with Vitamin D. Thiazide diuretics may increase blood calcium levels if taken with Vitamin D supplements. Corticosteroids can reduce Vitamin D metabolism, and some anti-seizure medications can increase Vitamin D breakdown. Additionally, cholesterol-lowering drugs like cholestyramine can impair Vitamin D absorption.
Yes, Vitamin A supplements can interact with certain medications. For example, some retinoid drugs used for acne or psoriasis can increase the risk of Vitamin A toxicity. Additionally, large doses of Vitamin A might interfere with the anticoagulant effects of warfarin, and tetracycline antibiotics may increase the risk of elevated intracranial pressure.
Vitamin A and Vitamin D both play crucial roles in calcium metabolism, bone health, and immune function, and they can influence each other's effects. Some research suggests that maintaining a balanced intake of both vitamins may be important for optimal physiological function and to mitigate potential adverse effects of very high doses of one or the other. Their precise interaction mechanisms are complex and involve nuclear receptors.

Vitamin A 75.0
The Vitamin A (Retinyl Palmitate) is in a good form and contributes effectively to Vitamin A needs, though its relatively high dose compared to Vitamin D means users should be aware of total Vitamin A intake.

The Vitamin D3 content at 135 IU is very low compared to commonly recommended daily intakes for adults (e.g., 1000-5000 IU), making it less effective for optimizing Vitamin D levels.
Goals

Vitamins A and D are beneficial for skin health and integrity, providing decent support for maintaining healthy skin structure and function.
General Health 60.0
Provides a foundational blend of fat-soluble vitamins and omega-3s beneficial for overall well-being, though at relatively conservative doses for comprehensive adult support.
