insights Analysis
KAL Bone Meal Powder stands out for its substantial quantities of calcium (1300mg) and phosphorus (440mg), both derived from bone meal, a natural source that includes microcrystalline hydroxyapatite. It also contains a small amount of magnesium. The appeal lies in its high dose and natural origin, which resonates with consumers seeking whole-food derived supplements. However, it notably omits Vitamin D and Vitamin K2, which are paramount for ensuring calcium is absorbed and directed efficiently to bones rather than soft tissues. Online reviews often praise its effectiveness for bone density and its cost-effectiveness, but some also mention the inconvenience of powder form and potential concerns about sourcing/purity of 'bone meal' if not a trusted brand, though KAL is generally reputable for testing. Nutritionists typically recommend co-factors alongside high-dose calcium.
- Provides a very high dosage of calcium (1300mg) and phosphorus (440mg) per serving.
- Source from bone meal provides natural microcrystalline hydroxyapatite (MCHA) and other trace minerals.
- Cost-effective for the amount of calcium provided.
- Lacks essential Vitamin D and Vitamin K2, which are crucial for calcium absorption and proper bone mineralization.
- Powder form may be less convenient for some users compared to capsules or gummies.
- Contains a very low amount of magnesium, which is an important co-factor for calcium metabolism.
- Ensure adequate intake of Vitamin D and K2 from other sources when using this product, as their absence can reduce calcium effectiveness and potentially lead to unwanted calcification in soft tissues.
- As with all bone meal products, it's prudent to confirm the brand's heavy metal testing and purity standards, although KAL is generally a reputable brand.

bolt Effectiveness for goals
Yes, calcium is a primary mineral for building and maintaining strong bones and teeth throughout life. Adequate calcium intake helps ensure bone density and can reduce the risk of osteoporosis. Its effectiveness in this role is well-established through numerous studies.
Calcium is a key mineral for building and maintaining strong bones throughout life. Supplementation can help ensure adequate intake, especially for individuals who do not consume enough through diet. It contributes to bone density and strength.
Calcium and phosphorus are synergistic, meaning they work in concert for maximum bone health. They combine to form the mineral matrix of bones, providing strength and rigidity. Maintaining a balanced intake of both is essential for effective bone development and maintenance.
Adequate calcium intake, often supported by supplementation, is crucial for bone health and can play a role in reducing osteoporosis risk. It works best when combined with sufficient vitamin D, which aids calcium absorption. Regular weight-bearing exercise is also important.
Supplemental calcium, especially when combined with vitamin D, is effective in supporting bone mineral density and can help reduce the risk of osteoporosis, particularly in individuals with inadequate dietary intake. Its effectiveness is greatest as a preventative measure rather than a standalone treatment for advanced disease. Regular intake within recommended limits is key.
schedule Dosage, timing & forms
The recommended daily allowance (RDA) for calcium for most adult men and women ranges from 1,000 to 1,200 milligrams per day, depending on age and gender. This includes calcium from both diet and supplements. Individual needs can vary based on factors like age, sex, and health status.
The Recommended Dietary Allowance (RDA) for calcium in most adults aged 19-50 is 1,000 mg per day. For women over 50 and men over 70, the RDA increases to 1,200 mg per day. These recommendations are designed to support bone health and other physiological functions.
Calcium carbonate and calcium citrate are two common forms of calcium supplements. Calcium carbonate is typically more concentrated but requires stomach acid for absorption, so it's best taken with food. Calcium citrate is well absorbed with or without food and may be a better option for individuals with low stomach acid.
Common forms include calcium carbonate and calcium citrate. Calcium carbonate is generally more economical and contains a higher percentage of elemental calcium, requiring stomach acid for absorption, so it's often taken with food. Calcium citrate is more easily absorbed, even without food, and may be preferred by individuals with low stomach acid.
For calcium carbonate, taking it with meals is generally recommended to optimize absorption due to the need for stomach acid. Calcium citrate can be taken at any time, with or without food. Spreading out calcium intake throughout the day in smaller doses may also improve absorption.
health_and_safety Safety & interactions
Yes, calcium supplements can interact with several medications, including certain antibiotics (like tetracyclines and fluoroquinolones), thyroid hormones, and some bisphosphonates. These interactions can reduce the absorption and effectiveness of the medication or the calcium. It is advisable to take these medications at separate times from calcium supplements.
Yes, calcium supplements can interact with several medications, including certain antibiotics (like tetracyclines and fluoroquinolones), thyroid hormones (levothyroxine), and bisphosphonates. These interactions can reduce the absorption or effectiveness of the medication or the calcium. It is advisable to consult a healthcare professional regarding potential interactions.
Consuming very high amounts of calcium, primarily from supplements, can lead to hypercalcemia, causing symptoms like nausea, constipation, and fatigue. Long-term excessive intake may also increase the risk of kidney stones and, in some cases, cardiovascular concerns. Adhering to recommended daily allowances is important.
For most adults, the tolerable upper intake level (UL) for calcium is 2,500 mg per day, though this can vary by age and specific health conditions. Exceeding this limit regularly can increase the risk of adverse effects. It is important to consider calcium intake from both diet and supplements when assessing total intake.
Yes, high doses of calcium supplements can potentially interfere with the absorption of some other essential minerals, including iron, zinc, and magnesium, when taken at the same time. To minimize this effect, it's often recommended to take calcium supplements at a different time of day from iron or zinc supplements.

Categories
Calcium 80.0
Provides a very high and effective dose of calcium from bone meal, which includes multiple forms. This makes it a strong choice for hitting daily calcium targets, though it still needs Vitamin D for optimal absorption.
Phosphorus 75.0
Delivers a substantial amount of phosphorus, well-proportioned to the calcium content from a natural source. This contributes effectively to the overall mineral balance for bone health.
Goals
Bone Health 75.0
It delivers a substantial dose of calcium and phosphorus from bone meal, a highly bioavailable source that inherently contains MCHA, making it a potent option for direct mineral input. However, the absence of crucial Vitamin D and K2 prevents it from achieving a perfect score for comprehensive bone support.
Heart Health 50.0
Calcium is vital for heart muscle function, but without Vitamin K2, there's a risk of calcium depositing in arteries. While the overall effect is positive for mineral intake, it's not optimized for heart health in terms of calcium direction.
Joint Health 40.0
While strong bones indirectly support joint function, this product does not contain specific ingredients like collagen, glucosamine, or chondroitin that are directly targeted at joint health or cartilage support.
