insights Analysis
21st Century's 600+D3 offers 600mg of elemental calcium as calcium carbonate, an ideal single dose for optimal absorption, paired with 20mcg (800 IU) of Vitamin D3, which is crucial for calcium uptake in the body. The product's price per serving ($0.03) is remarkably low, providing exceptional value. While it delivers key nutrients for bone health, it does not include Vitamin K2 or magnesium, which are important for comprehensive calcium management and preventing calcium from depositing in soft tissues. This is a very solid option for basic, cost-effective calcium and D3 supplementation.
- Exceptional value with an incredibly low price per serving.
- Contains an optimal 600mg elemental calcium dose for efficient absorption.
- Includes essential Vitamin D3, crucial for calcium absorption.
- Does not include Vitamin K2, which is important for proper calcium distribution and arterial health.
- Lacks synergistic minerals like magnesium, which also contribute to bone health.
- Calcium carbonate is best absorbed with food due to its requirement for stomach acid.
- For optimal benefits, consider supplementing with Vitamin K2, especially if taking calcium long-term.
- Take with meals to enhance calcium carbonate absorption.

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.
