An unhealthy diet, a sedentary lifestyle, poor sleep, the passage of time and genetics are factors that cause nutritional deficits<\/strong> that push us in the opposite direction of optimal health and well-being and reduce our stamina and energy. As Gloria Sabater, expert in Preventive Medicine at SHA, explains, \u201ceach person is genetically different<\/strong> and has a different lifestyle, so not all supplements are right for everyone. It is therefore essential to personalise and adapt supplementation<\/strong> to each individual\u2019s real needs\u201d.<\/p>\n A common mistake is to start taking a supplement that a friend, family member or co-worker is having success with. In fact, supplements should always be prescribed by a specialist after a detailed analysis of biomarkers<\/strong>. \u201cAt SHA, we have a wide range of options for all kinds of situations. Depending on the specific needs and objectives of each guest (sleep problems, weight loss<\/strong>, detox, controlling cholesterol or glucose levels, improving cognitive or neurological functions, strengthening immunity<\/strong>), we recommend one supplement or another\u201d, adds the doctor.<\/p>\n Of course, supplements<\/strong> are a tool that helps us to improve biomarkers, but they should never be used as a substitute for a healthy and balanced diet<\/strong>, regular physical exercise and, in general, healthy lifestyle habits. That said, and underscoring the importance of personalising treatment, Gloria tells us that most people are deficient in vitamin D and Omega-3. \u201cVitamin D<\/strong> is essential for strengthening the immune system, controlling inflammatory processes<\/strong> and combating osteoporosis, which is the reduction in bone density. Omega-3<\/strong> fatty acids, found mainly in oily fish, improve neurological function and vision, protect cardiovascular health<\/strong>, control inflammation and increase the flexibility of cell membranes. Despite the fact that we have many hours of sunshine a day in Spain (key to synthesising vitamin D) and, being surrounded by the sea, we have relatively easy access to fish, there is a generalised deficit<\/strong> of these two nutrients\u201d.<\/p>\n
