Dietary supplements can be beneficial for certain individuals, but they are not a replacement for a healthy diet. Supplements like multivitamins, probiotics, and vitamin D can support bone health and overall wellness if used correctly. Multivitamins provide a range of essential nutrients but should not be relied upon to prevent diseases. Probiotics help maintain a healthy gut, which can indirectly support nutrient absorption for bone health. Vitamin D is crucial for calcium absorption, which is vital for strong bones. Always consult with a healthcare provider before starting any supplement, as they can interact with medications and have side effects.
