Supplements I’d give to everyone’s parents and grandparents: 1. Creatine 2. Multivitamin 3. Omega-3s 4. Taurine 5. Glycine & NAC 6 …

what it claims

Siim Land recommends a list of six supplements for parents and grandparents: creatine, multivitamin, omega-3, taurine, glycine with NAC (GlyNAC), and astaxanthin.

Creatine is strongly supported by evidence (RCTs) to improve muscle mass, strength, and potentially cognition in seniors.

Creatine is strongly supported by evidence (RCTs) to improve muscle mass, strength, and potentially cognition in seniors. The GlyNAC combination has shown, in randomized clinical trials, promising results regarding oxidative stress, mitochondrial function, and physical strength. Omega-3s are widely recognized for cardiovascular and cognitive support. Astaxanthin, as an antioxidant, shows potential benefits in small studies on mobility and oxidative stress, but long-term evidence remains limited. Taurine is the subject of growing interest for metabolic and cardiac health, although direct evidence in elderly humans is less robust. Finally, the systematic use of a multivitamin for everyone is more nuanced: while it can address deficiencies, the literature does not demonstrate a systematic benefit for the prevention of chronic diseases in all healthy seniors.

Neurotransmitters play specific and defined roles in regulating our cognitive, emotional, and physiological functions (attention, motivation, relaxation, etc.).

Physical exercise follows a J-shaped curve regarding mortality risk: a lack of activity is deleterious, but an excess of exercise can also become detrimental to health.

The buzz from a Monster Energy comes almost entirely from its caffeine (and the sugar riding along with it) — the taurine and the B-vitamin megadoses on the can don't add a proven benefit beyond that.

Extreme, prolonged sun deprivation — like months aboard a nuclear submarine — is exactly the scenario where routine vitamin D supplementation makes real sense: several studies on submarine crews (Royal Navy, US Navy) show levels drop markedly within weeks without it.

Andy Galpin suggests a prioritized list of dietary supplements to support muscle gain during resistance training, placing protein, carbohydrates, creatine, omega-3s, and vitamin D at the top of the list, followed by secondary options such as magnesium, zinc, chromium, polyphenols, and probiotics.
