insights Analysis
FOCUSfactor is a multi-ingredient supplement formulated for cognitive support, containing a wide array of vitamins, minerals, and a large proprietary blend. However, its inclusion of Vitamin D is negligible at only 100 IU of D3. For adults aiming to meet recommended daily Vitamin D intake or address any of the specified health goals (General Health, Immunity, Bone Health, etc.), this dosage is profoundly insufficient. Nutritionists and public health guidelines advocate for much higher Vitamin D levels for these purposes. While it may offer other benefits from its extensive ingredient list, its extremely low Vitamin D content combined with a high cost per serving makes it completely unsuitable as a primary Vitamin D supplement and severely compromises its ability to fulfill Vitamin D-dependent goals.
- Contains Vitamin D3 (cholecalciferol) form.
- Includes a broad spectrum of other vitamins and minerals.
- Extremely low Vitamin D dosage (100 IU), entirely inadequate for adult needs.
- Very high price per serving, making it exceptionally poor value for Vitamin D.
- Primary ingredients are part of a proprietary blend, lacking transparency for specific doses.
- Not a dedicated Vitamin D supplement.
- This product is not a suitable source for Vitamin D supplementation due to its negligible dosage.
- Individuals should not rely on FOCUSfactor to meet their Vitamin D requirements.
- The proprietary blend means specific ingredient amounts are unknown, which can be a concern for some users.

bolt Effectiveness for goals
Vitamin D is primarily effective for maintaining bone health by facilitating the absorption of calcium and phosphorus, which are essential for bone mineralization. It plays a crucial role in preventing conditions like rickets in children and osteomalacia in adults. Additionally, it supports various other bodily functions.
Yes, Vitamin D is recognized for its role in modulating the immune system. It can influence the activity of immune cells and their responses, potentially contributing to the body's ability to fight off pathogens. While studies show a link, its direct impact on specific immune conditions is an ongoing area of research.
Vitamin D, particularly when combined with calcium, has been shown to be effective in reducing the risk of falls in older adults. This is primarily due to its positive impact on bone density and muscle strength, which are crucial for balance and stability. Maintaining adequate Vitamin D levels is an important aspect of fall prevention strategies.
Vitamin D plays a role in muscle function and can help maintain muscle strength. Adequate levels are associated with better physical performance and a reduced risk of falls, particularly in older adults. It is involved in muscle contraction and growth processes.
Some research suggests a correlation between Vitamin D levels and mood regulation, with studies exploring its potential influence on mental well-being. However, the evidence is not conclusive enough to establish a direct causal link or recommend it as a primary treatment for mood disorders. More research is needed in this area.
schedule Dosage, timing & forms
For many adults, the recommended dietary allowance (RDA) of Vitamin D is 600-800 International Units (IU) daily. However, individual needs can vary based on factors like age, sun exposure, and baseline vitamin D levels. It's important to consult a healthcare professional for personalized dosage recommendations.
Yes, Vitamin D is a fat-soluble vitamin, meaning it is best absorbed when taken with a meal containing some fat. Taking it with your largest meal of the day, or at least a meal with a source of fat, can significantly enhance its absorption. This improves its bioavailability in the body.
The tolerable upper intake level (UL) for Vitamin D for most adults is 4,000 IU per day. Consuming amounts significantly above this limit without medical supervision may increase the risk of toxicity, leading to hypercalcemia. Always adhere to recommended dosages unless advised otherwise by a healthcare provider.
Vitamin D3 (cholecalciferol) is generally considered more potent and effective at raising and maintaining circulating 25(OH)D levels in the blood compared to Vitamin D2 (ergocalciferol). Studies suggest D3 leads to a more sustained increase in Vitamin D status. Both forms convert to the active form, but D3 appears to do so more efficiently.
The two main 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. Supplements are available as capsules, tablets, liquids, and sprays.
health_and_safety Safety & interactions
Excessively high doses of Vitamin D can lead to vitamin D toxicity, also known as hypervitaminosis D. This condition can cause a dangerous buildup of calcium in the blood (hypercalcemia), leading to symptoms like nausea, vomiting, weakness, and kidney problems. It typically occurs from megadoses of supplements, not from sun exposure or diet.
Yes, Vitamin D can interact with certain medications. These may include steroids, weight-loss drugs like orlistat, cholesterol-lowering statins, and some diuretics. It is important to discuss all medications and supplements with a healthcare provider to avoid potential interactions.
Symptoms of Vitamin D toxicity, or hypercalcemia, can include nausea, vomiting, loss of appetite, excessive thirst, and frequent urination. More severe signs might involve kidney problems, bone pain, and confusion. If these symptoms occur, discontinue supplementation and seek medical attention.
Vitamin D is generally considered safe and often recommended during pregnancy and breastfeeding, as it supports maternal and infant health. However, it is crucial to follow the dosage recommendations provided by a healthcare provider. Excessive amounts should be avoided.
Yes, individuals with conditions causing hypercalcemia (high blood calcium) should generally avoid Vitamin D supplementation. Vitamin D increases calcium absorption, which could worsen already elevated calcium levels. Always consult a doctor if you have such a condition.

Categories
Vitamin D 5.0
As a Vitamin D product, its 100 IU dosage is critically low and fails to meet even basic adult requirements, making it completely unsuitable as a primary Vitamin D source despite being D3.
Goals
General Health 5.0
The 100 IU of Vitamin D3 is a negligible amount for adult general health, far below any recommended intake for meaningful benefits or even basic deficiency prevention.
Immunity 5.0
This dosage is completely insufficient for providing any meaningful support to the immune system, as robust immune function requires significantly higher Vitamin D levels than 100 IU can provide.
Bone Health 5.0
100 IU of Vitamin D is almost entirely ineffective for promoting bone health or significantly aiding calcium absorption, especially for adults.
