Supplements for Energy: What Is Worth It and What Is a Waste of Money
Supplements promise energy in a capsule. The reality is more nuanced: they can help specific problems, but they do not replace sleep, food and movement.
The basic rule
Supplements fill gaps. If you do not have a gap, extra amounts rarely give extra energy.
Worth considering
| Supplement | When it may help |
|---|---|
| Vitamin D | Low sunlight, confirmed low levels |
| Iron | Confirmed deficiency or anemia |
| B12 | Vegan or vegetarian diets, some conditions |
| Magnesium | Low intake, may help sleep for some |
| Omega 3 | If you rarely eat oily fish |
| Creatine | Strength training and performance |
| Caffeine | Alertness in moderate doses |
Often a waste
- Mega dose vitamin blends
- Energy shots with sugar and high caffeine
- "Detox" products
- Proprietary blends that hide doses
How to choose safely
- Test first when possible.
- Choose one at a time so you know what works.
- Look for third party testing.
- Check doses and avoid exceeding upper limits.
- Tell your doctor about what you take.
Food first
Eat protein, vegetables, fruit, whole grains and oily fish regularly. Use the 7 Day Meal Plan as a base.
Caffeine note
Caffeine is the most effective legal energy supplement, but timing matters. See Caffeine and Energy.
Supplements can interact with medicines and may be unsafe with certain conditions. Check with your doctor or pharmacist before starting any supplement.
Frequently asked questions
Should I take a multivitamin?
It can fill small gaps, but it will not fix poor sleep or diet.
Do energy drinks help?
They give a short boost and can worsen sleep and anxiety.
How long before supplements work?
If you are deficient, weeks. If not, you may notice nothing.
