Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. Our assessment is that while calcium is a well-established nutrient, the specific formulation of this product — Physician's Signature Formula #1 OC-Classic With Fresh Royal Jelly — does not have specific data or studies provided to evaluate its unique blend. We focus strictly on the calcium content here, as that is the only ingredient with data available.
How it works
Calcium acts as a master regulator for your bones and muscles. It supports bone mineralization, helping to deposit minerals and maintain bone density. It also supports neuromuscular relaxation, meaning it helps your muscles relax and nerves signal properly [NIH ODS]. Think of calcium as the building block your body relies on for structural strength and everyday movement.
Safety profile
Data not available on specific side effects for this product alone. However, the FDA has received 592,059 total adverse event reports for all dietary supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because no specific study or dosage for this product is provided, our recommendation is to be cautious. If you are considering this product, check the label for the exact calcium dose. You should not exceed the tolerable upper intake level without medical supervision. Always take calcium supplements with food and separate from other medications by at least 2 hours to avoid absorption issues [NIH ODS]. Consult your healthcare provider before starting, especially if you take prescription medications or have kidney concerns.
