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 ironcan 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.
