Dr. Sinatra Magnesium Broad-Spectrum Complex
Brand: Dr. Sinatra · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains calcium, a mineral with well-documented benefits for bone health. However, we must be clear: the data provided does not include a full ingredient list for Dr. Sinatra Magnesium Broad-Spectrum Complex, and the adverse event data is for all supplements, not this specific product [FDA data]. Our assessment is that a broad-spectrum magnesium complex can be a thoughtful choice for supporting multiple body systems, but you need to verify the exact dosage of each ingredient on the label.
How it works
Calcium acts as a master regulator for bone mineralization, supporting bone density and mineral deposition [NIH ODS]. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS]. Think of it as a foundational mineral that works alongside magnesium to maintain proper muscle and nerve function.
Safety profile
FDA received 592,059 total adverse event reports across all dietary supplements, but data for this specific product is not available [FDA data]. For calcium specifically, very high intakes can lead to constipation, nausea, and abnormal heart rhythms [NIH ODS]. High levels in the blood may also cause poor muscle tone, poor kidney function, extreme tiredness, and a high risk of death from heart disease [NIH ODS]. You should be aware that calcium can reduce absorption of bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by reading the label carefully to confirm the exact amounts of calcium and magnesium per serving. If you take thyroid medication, antibiotics, or bisphosphonates, take this supplement at least 2 hours apart from those medications [NIH ODS]. For most adults, aim for a total calcium intake of 1,000–1,200 mg daily from food and supplements combined, and discuss your individual needs with your healthcare provider [NIH ODS].
