Windmill Calcium & Magnesium

Our assessment

Our assessment: The evidence shows that Windmill Calcium & Magnesium provides two essential minerals for bone health and muscle function. However, without specific dosage amounts per serving from the product label, we cannot verify if it meets the recommended daily intake. Data not available on exact milligram amounts per tablet.

How it works

Think of calcium and magnesium as a team — calcium supports strong bones and teeth, while magnesium helps your body absorb calcium and supports muscle and nerve function [NIH ODS]. They work together to maintain bone density and normal heart rhythm [NIH ODS].

Safety profile

Data not available on adverse event reports specific to Windmill Calcium & Magnesium from FDA data. General side effects for calcium supplements can include constipation and bloating [NIH ODS]. For magnesium, high doses may cause diarrhea and stomach upset [NIH ODS].

Our recommendation

Start by checking your current calcium and magnesium intake from food. Data not available on the specific ratio in this product. Choose a supplement with a balanced calcium-to-magnesium ratio, and take with food for best absorption [NIH ODS].

Supplement labels contain several key sections regulated by the FDA:

• 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.
