Supplementation Framework<\/strong><\/p>\n\n\n\n<p>A useful way to think about supplementation is:<\/p>\n\n\n\n<p><strong>AGE \u2192 DIET \u2192 TRAINING \u2192 SLEEP \u2192 DEFICIENCIES \u2192

Age<\/strong><\/p>\n\n\n\n<p>Nutritional priorities can change across the lifespan.<\/p>\n\n\n\n<p>For example, maintaining adequate protein intake and resistance training becomes increasingly important for preserving muscle and physical function as people age.<\/p>\n\n\n\n<p>A 2026 systematic review found that protein supplementation, particularly when combined with exercise, can support muscle mass and physical performance in older adults, although results vary across interventions and populations.<\/p>\n\n\n\n<p>The implication isn&#8217;t that every older person needs protein powder.<\/p>\n\n\n\n<p>It is that <strong>protein requirements and muscle preservation deserve greater attention with ageing.<\/strong><\/p>\n\n\n\n<p><strong>2. Diet Comes First<\/strong><\/p>\n\n\n\n<p>Before adding five supplements, look at the diet.<\/p>\n\n\n\n<p>Is the person eating enough:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Protein?<\/li>\n\n\n\n<li>Fruit and vegetables?<\/li>\n\n\n\n<li>Whole grains?<\/li>\n\n\n\n<li>Healthy fats?<\/li>\n\n\n\n<li>Fibre?<\/li>\n\n\n\n<li>Calcium-rich foods?<\/li>\n\n\n\n<li>Iron-rich foods?<\/li>\n\n\n\n<li>Adequate total calories?<\/li>\n<\/ul>\n\n\n\n<p>A supplement should ideally <strong>fill a genuine nutritional gap<\/strong>, rather than become a substitute for a poor diet.<\/p>\n\n\n\n<p>This is particularly relevant to longevity.<\/p>\n\n\n\n<p>There is growing interest in supplements that target ageing pathways, but recent reviews continue to find that evidence varies considerably between nutrients and compounds. Protein and some targeted nutritional interventions have stronger practical relevance to muscle and physical function than many of the more speculative \u201canti-ageing\u201d products.<\/p>\n\n\n\n<p><strong>3. Training Changes the Equation<\/strong><\/p>\n\n\n\n<p>An athlete&#8217;s nutritional requirements can be very different from those of a sedentary individual.
