Calcium (Ca) is an essential mineral important for building and maintaining strong bones and teeth. It also supports muscle function, nerve communication, and heart health. Calcium is commonly found in dairy products, leafy green vegetables, and fortified foods. Many individuals, especially older adults and those with limited dairy intake, may need supplements. Insufficient calcium levels can lead to decreased bone density and other health issues, making it particularly important for healthy aging.

Calcium

Phosphorus (P) is an essential mineral that supports the development of strong bones and teeth. It plays a vital role in how the body processes carbohydrates and fats and is involved in producing proteins needed for cell growth, maintenance, and repair. Phosphorus also helps generate ATP, the molecule responsible for storing energy in the body. It’s commonly found in foods such as meat, fish, dairy, nuts, and beans, and a balanced diet usually provides adequate amounts. However, deficiencies can occur, especially in certain health conditions.

Phosphorus

Silicon is a trace mineral that supports bone strength and promotes healthy skin, hair, and nails. It is commonly found in grains, fruits, and vegetables, making it easy to obtain through diet. Silicon may also help prevent osteoporosis by contributing to bone mineral density.

Silicon

Sodium (Na) is an essential mineral that plays a crucial role in nerve signaling, muscle function, and regulating blood pressure and fluid balance. It helps maintain proper hydration and supports communication between nerves and muscles. Sodium is commonly found in salt, processed foods, and many snacks. However, excessive sodium intake can lead to health issues such as high blood pressure.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the USA. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
