No supplement makes up for a poor or one-sided eating pattern. That is my starting point for everything I list below: supplements are at most a targeted addition, never a replacement for healthy food.
Which Supplements Proved Truly Worthwhile for Me
The market for dietary supplements is enormous, but you do not need most of it. After a lot of trial and error, a few targeted basics remained for me:
- Protein powder (whey or plant-based): a practical, quick way to hit your daily protein goal on busy days without effort.
- Vitamin D3: important for strong bones, good muscle function, and supporting your immune system, especially as your body’s own production through the skin declines.
- Omega-3 (fish oil or algae oil): a supplement that contributes to normal heart function, for the days when there is no fatty fish (such as salmon or mackerel) on the menu.
- Magnesium: plays an important role in the normal functioning of your muscles and nervous system.
Hydration: The Most Underrated “Performance Booster”
It does not come in a bottle on the supplement shelf, and yet it is the thing most quickly forgotten: drinking enough water.
Aim for 1.5 to 2.5 liters (about 6 to 10 cups) of water a day, and drink more during heavy workouts, heavy sweating, or hot weather. Good hydration can influence your muscle strength, your concentration, and the speed of your recovery.

This is my experience, not medical advice. If you have doubts or take existing medication, always talk to a doctor or pharmacist before adding supplements. You will find more background in “The Power of 50+.”
