Physio Vites Magnesium Citrate

Our assessment

The evidence shows that Physio Vites Magnesium Citrate is a product designed to deliver magnesium, but based on the data provided, the key ingredient information available relates to calcium. Data for the specific magnesium citrate ingredient is not available. Our assessment must focus on the calcium data provided, as it is the only ingredient with supporting documentation. We cannot evaluate the benefits or risks of magnesium citrate itself from this data set.

How it works

Think of calcium as a structural and signaling mineral. It supports bone density and mineral deposition, which is critical for skeletal strength. It also plays a role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. These mechanisms highlight calcium's importance for both your bones and your nervous system.

Safety profile

FDA received 592,059 total adverse event reports for all products in the database. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Because the data provided does not include specific information on magnesium citrate, we cannot recommend Physio Vites Magnesium Citrate for any specific purpose. If you are considering this product for magnesium supplementation, data not available prevents us from offering guidance. For calcium, you should be cautious with high intakes and consult your healthcare provider, especially if you take medications that interact with calcium [NIH ODS]. We recommend relying on a healthcare professional to determine your individual needs.

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
