What supplements should a man take who’s over 40

There isn’t a standard supplement stack just because a man is over 40. The guidance here is to start with sleep, exercise, and nutrition, and use supplements selectively rather than treating age alone as a reason to take them. 1 2

• Creatine: One clinician discusses it as an option, noting effects on energy systems and a slight increase in total testosterone; that is not a guarantee of a meaningful hormone benefit for every man. 3
• Magnesium, vitamin D, and omega-3s: These came up among commonly used supplements, but the discussion does not establish that every man over 40 needs them; the guest framed supplementation around covering potential gaps or specific reasons. 4 5
• Check before adding hormone-focused supplements: The advice is to prioritize lifestyle and consider testing hormone levels; the discussion cautions against jumping to testosterone therapy without considering behavior, nutrition, and medical guidance. 6

So the practical takeaway is to tailor any supplements to diet, goals, and relevant testing—not age alone.
