Getting regular exercise, eating a balanced diet, maintaining low stress levels, and getting enough sleep each night can all help maintain good energy levels. Can vitamins and supplements also help?
Sometimes, people might need an extra boost of energy when life gets busy or during particularly intensive exercise.
Here, we look at some of the most effective vitamins and supplements for boosting energy levels.
Ashwagandha is an adaptogen that could help boost energy levels. Adaptogens are plant derived substances that help the body better manage stress.
The researchers behind a
They also found ashwagandha to be “safe and well-tolerated.”

Coenzyme Q10 (CoQ10) is an enzyme that exists naturally in the body, particularly in the heart, liver, pancreas, and kidneys. It is an antioxidant that
- oily fish
- liver or other organ meats
- whole grains
People with certain health conditions and those not getting enough from their diet might wish to ask their doctor about supplementing with CoQ10.
Mild side effects of CoQ10 might include:

Certain people are more at risk of being deficient than others, including:
- older adults
- people with darker skin
- people who get less sun exposure, such as those in colder climates
- people with obesity
The researchers behind a 2013 study found that people with low vitamin D levels had improved muscle efficiency after they received treatment for the vitamin deficiency.
There is also a link between depression and low levels of vitamin D. Fatigue is a common symptom of depression.
One review highlighted a Norwegian study in which more than 400 people with overweight received

Some athletes take vitamin B-12 supplements to boost their performance. However, research does not indicate that B-12 increases sports performance or endurance in people who have no deficiency.
Asking a doctor about a potential deficiency and maintaining good levels of vitamin B-12 may help a person treat low energy that is due to a deficiency.
Creatine is an amino acid that occurs mostly in red meat and seafood. Creatine supplementation increases creatine stores in the muscles and can help improve performance during exercise.
A review in the Journal of the International Society of Sports Nutrition found that creatine was effective in improving performance in high intensity exercise, as well as:
- improving recovery
- helping prevent sports-induced injuries
- reducing the risk of heat-related illness, such as dehydration, when exercising
The study authors also found that both long and short term supplementation is safe and well-tolerated for healthy people of all ages.
It is important to note that some of the researchers received funding from or had affiliations with supplement manufacturers.
A deficiency in iron can lead to a lack of energy and fatigue. People who have a
- are menstruating
- are pregnant or breastfeeding
- are vegetarian or vegan
- exercise intensely, especially if female
- donate blood regularly
One study looked at unexplained fatigue in menstruating women. The participants who supplemented with iron over 12 weeks had a 47.7% decrease in fatigue. Those in the placebo group had a decrease of just 28.8%.
Eating iron-rich foods with vitamin C can increase absorption, so people should be sure to consume enough fruits and vegetables, especially citrus fruits and leafy greens.
L-theanine is a naturally occurring amino acid in tea. Combining L-theanine with caffeine may help increase energy and cognitive performance.
A small 2017 study looked at the effects of L-theanine and L-theanine with caffeine on attention levels in 20 healthy males. The researchers found that high doses of L-theanine with caffeine improved attention levels the most.
Another study from 2010 found that a combination of 97 mg of L-theanine and 40 mg of caffeine improved cognitive performance in young adults. The participants reported feeling less tired with increased alertness.
Vitamins and supplements can cause mild side effects in some people. If a person experiences any severe side effects from supplements, they should stop using them straight away and see a doctor.
The risks of taking supplements and vitamins include:
- Ashwagandha: This herb is generally safe, but it has links to liver damage in rare cases.
- CoQ10: This supplement may interact with blood thinners and insulin medications.
- Vitamin D: It is impossible for a person to get too much vitamin D from the sun, but taking too many vitamin D supplements can cause adverse symptoms and dangerously raise blood levels of calcium.
- Vitamin B: There are no adverse effects associated with taking vitamin B.
- Creatine: This supplement may cause weight gain, as it draws water from the body toward the muscles. People should be sure to drink extra fluids to stay hydrated.
- Iron: Although iron poisoning is rare, taking too much iron can cause an upset stomach, nausea, abdominal pain, and vomiting.
- L-theanine: This supplement contains caffeine and may cause sleep problems and other unwanted effects in some people.
Some supplements can interact with certain medications. If a person is taking medications for an existing health condition, it is best to speak to a doctor or pharmacist about possible interactions before taking a supplement.
Women who are pregnant or breastfeeding should also speak to a doctor before taking any new supplements.
Alongside a healthful diet and plenty of exercise, people may find that the vitamins above help boost energy levels and increase performance during exercise.
However, people should check with their doctor before taking any supplements if they are taking other medications or have an existing health condition.
