insights Analysis
Solaray's Cal-Mag Citrate 1:1 ratio product provides an exceptionally high dose of both calcium (2000mg) and magnesium (2000mg) in a balanced 1:1 elemental ratio. It includes both calcium citrate and magnesium citrate, which are highly bioavailable forms and generally well-tolerated. However, the formulation is significantly hampered by the inclusion of calcium hydroxide and magnesium oxide. Both of these forms are known for their very poor systemic absorption; calcium hydroxide can be particularly irritating and magnesium oxide primarily acts as a laxative, meaning that a substantial portion of these high doses may not be effectively absorbed or utilized by the body for its intended physiological functions. Furthermore, a critical oversight for a bone health supplement is the complete absence of Vitamin D, which is essential for calcium absorption. Without Vitamin D, the body struggles to integrate calcium into bones, severely limiting the benefits of even the absorbable citrate components. The high price per serving ($0.71) is not fully justified given these bioavailability limitations and the lack of Vitamin D.
- Offers a very high dose of calcium (2000mg) and magnesium (2000mg) in a 1:1 ratio.
- Includes calcium citrate and magnesium citrate, which are highly bioavailable forms.
- Available from a reputable brand (Solaray).
- Does not contain any Vitamin D, which is essential for calcium absorption and utilization for bone health.
- Contains calcium hydroxide and magnesium oxide, both of which are poorly absorbed and can cause digestive issues.
- The exceptionally high doses may be unnecessary for many individuals and could lead to digestive upset.
- High price per serving ($0.71) given the inclusion of less bioavailable forms and absence of Vitamin D.
- Due to the high doses and inclusion of poorly absorbed forms, digestive upset (e.g., diarrhea) is a significant possibility.
- Must be supplemented with Vitamin D to facilitate calcium absorption for bone health.
- These very high doses are typically meant to be split into multiple servings throughout the day, which may not be clear to all users.

bolt Effectiveness for goals
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 55.0
While calcium citrate is a good form, a significant portion comes from calcium hydroxide, which is poorly absorbed and can be irritating, limiting overall bioavailability.
Magnesium 55.0
The blend includes good magnesium citrate, but the very large amount of poorly absorbed magnesium oxide significantly reduces its overall systemic bioavailability and effectiveness.
Goals
Heart Health 60.0
Contains calcium and magnesium but the significant reliance on poorly absorbed oxide and hydroxide forms limits its potential to effectively support cardiovascular function and blood pressure regulation.
Stress Relief 60.0
Magnesium citrate offers some calming benefits, but the very large dose of poorly absorbed magnesium oxide means its overall effectiveness for stress reduction is diluted and may cause digestive issues.
Sleep Support 60.0
Magnesium citrate can promote relaxation for sleep, but the very large dose of poorly absorbed magnesium oxide reduces its overall effective support for improving sleep quality and may cause digestive discomfort.
