insights Analysis
KAL Dolomite Powder presents itself as a straightforward, economical option for calcium and magnesium supplementation in a versatile powder format. Sourced naturally as dolomite, it provides calcium and magnesium in carbonate forms and maintains a reasonable calcium to magnesium ratio of approximately 1.7:1. The powder form allows for flexible dosing and mixing into beverages. However, the reliance solely on carbonate forms for both minerals is a significant drawback, as these are among the least bioavailable and require adequate stomach acid for absorption, potentially causing digestive discomfort for some. More critically, the complete absence of Vitamin D is a major impediment to the product's efficacy, especially for bone health goals. Without Vitamin D, the body struggles to absorb and utilize calcium effectively, severely limiting the benefits of the elemental calcium provided. While cheap, its limitations mean it's not a comprehensive or highly effective solution for mineral repletion.
- Very affordable price per serving, making it a budget-friendly option.
- Powder form offers versatility in dosing and consumption.
- Provides a reasonable calcium to magnesium ratio (~1.7:1).
- Contains no Vitamin D, which is essential for calcium absorption and utilization for bone health.
- Both calcium and magnesium are in carbonate forms, which are among the least bioavailable and require sufficient stomach acid for absorption.
- Dolomite sources can sometimes raise concerns about heavy metal contamination, though reputable brands typically test for this.
- Consumers must supplement with Vitamin D separately to achieve any meaningful calcium absorption for bone health.
- Individuals with low stomach acid or digestive sensitivities may experience poor absorption and/or digestive upset from the carbonate forms.

Calcium is a crucial mineral for building and maintaining strong bones throughout life. Supplementation can help ensure adequate intake, particularly when dietary sources are insufficient. It is often recommended in conjunction with Vitamin D for optimal bone mineral density.
Calcium is a crucial mineral for building and maintaining strong bones throughout life. Calcium supplements are often used to help meet daily requirements, especially when dietary intake is insufficient. Adequate calcium intake, combined with vitamin D, is important for bone density.
Magnesium plays a key role in muscle contraction and nerve function. Some studies suggest that magnesium supplementation may help reduce the frequency and intensity of muscle cramps, particularly in individuals with a magnesium deficiency. It is not a guaranteed remedy for all types of cramps.
Magnesium plays a vital role in muscle contraction and relaxation. Some research suggests that magnesium supplementation may help alleviate muscle cramps, particularly in individuals with a deficiency or specific conditions like pregnancy. However, evidence is mixed, and more research is needed.
Adequate calcium intake throughout life is essential for reducing the risk of osteoporosis. Calcium supplements may help some individuals meet their daily calcium needs, which is a factor in osteoporosis prevention. However, other factors like vitamin D, exercise, and genetics also play significant roles.
schedule Dosage, timing & forms
Yes, calcium and magnesium can generally be taken at the same time, though some experts suggest separating them for optimal absorption of both. High doses of one mineral might interfere with the absorption of the other, especially if absorption sites are shared. Consider taking them at different meals or times of the day.
For most adults, the recommended daily allowance (RDA) for calcium is 1,000 mg per day. For women over 50 and men over 70, this increases to 1,200 mg per day. These recommendations include calcium obtained from both food and supplements.
The recommended dietary allowance (RDA) for calcium for most adults aged 19-50 years is 1,000 mg per day. For women over 50 and men over 70, it increases to 1,200 mg daily. It's advisable to check with a healthcare provider for personalized recommendations.
Calcium carbonate supplements are best absorbed when taken with food because stomach acid helps with absorption. Calcium citrate can be taken with or without food. To maximize absorption and minimize side effects, it's often recommended to split calcium doses, taking no more than 500-600 mg at a time, throughout the day.
The recommended dietary allowance (RDA) for magnesium for adult men is generally 400-420 mg, and for adult women, it is 310-320 mg. These recommendations may vary based on age, sex, and specific health conditions. Always consult a healthcare professional for personalized dosage advice.
health_and_safety Safety & interactions
Generally, calcium and magnesium supplements can be taken together without significant issues for most people. Some sources suggest separating them by a few hours, especially if taking high doses, to optimize absorption. However, for typical standard doses, simultaneous intake is generally acceptable.
Both calcium and magnesium can interact with various medications, including certain antibiotics (like tetracyclines and quinolones), thyroid hormones, and bisphosphonates. These minerals can reduce the absorption of some drugs, requiring specific timing of doses. It is crucial to consult a healthcare provider when combining supplements with medications.
Yes, calcium supplements can interact with certain medications, including some antibiotics (like tetracyclines and fluoroquinolones), thyroid hormones (levothyroxine), and diuretics. Calcium can reduce the absorption of these drugs. It is advisable to take calcium supplements a few hours apart from these medications.
High doses of calcium supplements may lead to side effects such as constipation, bloating, and gas. Very high calcium intake can sometimes result in hypercalcemia, which may cause nausea, vomiting, and confusion. It is important to adhere to recommended daily allowances to minimize risks.
Magnesium supplements can interact with several medications, including some antibiotics (tetracyclines and quinolones), diuretics, and proton pump inhibitors. It may also affect the absorption of bisphosphonates and certain heart medications. Consult a healthcare professional if you are taking other medications.

Categories
Calcium 45.0
Calcium is provided as calcium carbonate, which is poorly absorbed without sufficient stomach acid and is less effective than other forms like citrate or malate.
Magnesium 40.0
Magnesium is exclusively in the carbonate form, which has low systemic bioavailability and is more likely to cause laxative effects than provide broad physiological benefits.
Goals
Joint Health 45.0
Offers basic mineral components for skeletal structure, but the low bioavailability and lack of Vitamin D significantly restrict its direct or indirect benefits for joint health.
Heart Health 45.0
Contains calcium and magnesium, but the poor absorption of both carbonate forms limits their effective contribution to cardiovascular function and blood pressure regulation.
General Health 45.0
Provides basic minerals but is severely deficient due to the absence of Vitamin D and the use of less-absorbed forms, making it an incomplete option for overall wellness.
