Your body typically needs nutritional supplements when it's unable to obtain all the essential nutrients it requires from your regular diet. There are several reasons for this:


1. Nutrient Deficiency: Some individuals may not consume a balanced diet, leading to deficiencies in essential vitamins and minerals.


2. Dietary Restrictions: People with certain dietary restrictions, such as vegetarians or vegans, may lack specific nutrients found primarily in animal products.


3. Medical Conditions: Certain medical conditions or surgeries can affect nutrient absorption, making supplementation necessary.


4. Age: As people age, their nutritional needs can change, and supplementation may be required to address deficiencies common in older adults.


5. Lifestyle: Athletes, pregnant women, and individuals with high-stress levels may have increased nutrient needs that are challenging to meet through diet alone.


6. Geographic Factors: Geographical location can influence nutrient availability. For example, individuals in regions with limited sunlight may require vitamin D supplements.


It's important to note that while supplements can be beneficial, they should not replace a healthy diet. Consulting a healthcare professional before starting any supplementation regimen is advisable to ensure it's appropriate for your specific needs and doesn't pose any health risks.
