insights Analysis
This product provides 500mg of elemental calcium from oyster shell (a form of calcium carbonate) along with 5mcg (200 IU) of Vitamin D3. The inclusion of Vitamin D3 is a significant advantage, as it is absolutely essential for the absorption of calcium in the gut, making the calcium more effective for its intended goals. The price point is remarkably low, offering excellent value. However, like many basic calcium supplements, it lacks magnesium, which is crucial for bone formation and regulating calcium levels, and Vitamin K2, which helps ensure calcium is deposited in bones rather than soft tissues like arteries. While effective for basic calcium and D supplementation, it doesn't offer the comprehensive mineral profile found in some higher-end bone health formulas.
- Extremely cost-effective, offering one of the lowest prices per serving on the market.
- Includes Vitamin D3, which is essential for calcium absorption and utilization.
- Provides a decent 500mg elemental calcium per serving, suitable for splitting doses or complementing dietary intake.
- Uses oyster shell calcium (calcium carbonate), which may cause digestive issues for some and requires stomach acid for absorption.
- Lacks magnesium and Vitamin K2, both important co-factors for optimal bone mineralization and cardiovascular health.
- Vitamin D3 dose (200 IU) is on the lower side, and some individuals may require more for optimal levels.
- Individuals with low stomach acid may find calcium carbonate less absorbable, potentially necessitating a calcium citrate form.
- Consult a healthcare professional if you have pre-existing kidney conditions or are on medications that interact with calcium or Vitamin D.

bolt Effectiveness for goals
Yes, vitamin D is essential for the effective absorption of calcium in the intestines. Without sufficient vitamin D, the body cannot absorb calcium properly, even if calcium intake is adequate. This partnership is crucial for maximizing calcium's benefits for bone health.
Adequate calcium intake, especially when combined with sufficient vitamin D, is important for bone health and may help reduce the risk of osteoporosis. It provides the necessary minerals for bone density. However, it's one of several factors in osteoporosis prevention and management.
Calcium is a primary mineral component of bones and teeth. Adequate intake is essential for maintaining bone density throughout life and plays a crucial role in bone formation and remodeling. Consistent supply helps support strong skeletal structure.
Calcium is a crucial mineral for maintaining strong bones throughout life, acting as a primary building block for bone tissue. Adequate calcium intake helps to support and maintain bone density. It is essential for the continuous remodeling process of bones.
Calcium, especially when combined with vitamin D, is an important nutrient for maintaining bone health. Consistent intake helps support bone density, which can contribute to reducing the risk of osteoporosis. However, it is one factor among many in preventing this condition.
schedule Dosage, timing & forms
For most adults aged 19-50, the recommended daily intake of calcium is typically 1,000 mg. This recommendation may vary slightly based on age, gender, and life stage, such as during adolescence or older adulthood.
The recommended dietary allowance (RDA) for most adult men and women aged 19-50 years is 1,000 mg per day. For women over 50 and all adults over 70, the RDA increases to 1,200 mg per day. These recommendations include calcium from both food and supplements.
The two most common forms of calcium in supplements are calcium carbonate and calcium citrate. Calcium carbonate is generally more affordable and contains a higher percentage of elemental calcium, while calcium citrate is well-absorbed with or without food.
Yes, calcium supplements can interact with certain medications, including some antibiotics, thyroid hormones, and bisphosphonates. It is generally advised to take calcium supplements at a different time of day from these medications to avoid interference with absorption. Always consult a healthcare professional about potential interactions.
Calcium carbonate is the most common and inexpensive form, containing 40% elemental calcium, and is best taken with food for optimal absorption. Calcium citrate contains 21% elemental calcium, can be taken with or without food, and may be better for individuals with low stomach acid. Your specific needs may influence which form is more suitable.
health_and_safety Safety & interactions
Yes, calcium supplements can interact with several medications, potentially affecting their absorption or efficacy. These include certain antibiotics (e.g., tetracyclines, fluoroquinolones), thyroid hormones (e.g., levothyroxine), bisphosphonates, and some diuretics. It is advisable to consult a healthcare professional or pharmacist regarding potential interactions with any medications you are taking.
Yes, calcium supplements can interact with several medications, potentially affecting their absorption or efficacy. These include certain antibiotics (e.g., tetracyclines, fluoroquinolones), thyroid hormones (e.g., levothyroxine), bisphosphonates, and some blood pressure medications. It is advisable to consult a healthcare professional regarding potential interactions and timing of doses.
Common side effects of calcium supplements may include constipation, bloating, and gas. These effects are usually mild and can sometimes be alleviated by adjusting the dosage or type of calcium, or by taking the supplement with food. If side effects persist, consulting a healthcare professional is recommended.
Yes, excessive intake of calcium, especially from supplements, can lead to hypercalcemia, a condition where calcium levels in the blood are too high. Symptoms can include nausea, vomiting, confusion, and kidney problems. Adhering to the Tolerable Upper Intake Level (UL) for calcium, which varies by age, is important.
Vitamin D plays a crucial role in helping the body absorb calcium from the gut. Therefore, adequate vitamin D levels are essential for calcium to be utilized effectively by the body for bone health. Many calcium supplements include vitamin D to enhance this absorption.

Categories
Calcium 75.0
An excellent budget-friendly calcium supplement due to its inclusion of Vitamin D3 and decent elemental calcium content. Its primary limitation is the lack of a broader spectrum of essential co-factors beyond Vitamin D for comprehensive calcium metabolism.
Goals
Bone Health 75.0
The inclusion of Vitamin D3 significantly boosts its efficacy for bone health by improving calcium absorption. However, the absence of magnesium and Vitamin K2 means it's not a complete bone support formula for optimal density and strength.
Fitness 70.0
Essential for muscle contraction and nerve impulses, the calcium and Vitamin D combination adequately supports these physiological functions critical for fitness. It provides a solid foundation, though additional minerals could offer more comprehensive support.
Heart Health 65.0
Calcium is important for heart function, and Vitamin D supports overall cardiovascular health. The main concern is the absence of Vitamin K2, which is critical for directing calcium to bones and preventing arterial calcification, making it less ideal for comprehensive heart support.
