- Billionaire entrepreneur Mark Cuban is known for his role on Shark Tank and as the owner of the Dallas Mavericks.
- Recently he’s been pivoting towards healthcare with the creation of his own drug company.
- To keep himself healthy, Cuban takes three daily supplements including melatonin, vitamin D and vitamin E.
Billionaire entrepreneur Mark Cuban has been going through some changes recently. At the end of November, Cuban announced that he would be wrapping up his decade-long stint on ABC’s Shark Tank. It was also recently reported that he may be selling his majority stake in the Dallas Mavericks.
One thing that doesn’t seem to be changing, however, is his commitment to health — both in his professional and personal life.
In January 2022, he launched his own drug company, Mark Cuban Cost Plus Drug Company, aimed to cut costs on prescription drugs. And earlier this year he invested in the mail-order medication company TruePill.
To support his own health, Cuban, 65, told Business Insider that he takes a few supplements daily that can help with sleep, protect bone health, and decrease inflammation.
Here are the three supplements Cuban takes.
Cuban told BI in an email that he takes a melatonin supplement every night.
Melatonin is a hormone produced by the body that helps regulate your sleep/wake cycle. Melatonin levels drop during the day in response to sunlight, and rise again in the evening making you feel sleepy.
A 2013 meta-analysis found that people who took a melatonin supplement fell asleep about 7 minutes faster, and slept for 8 minutes longer.
If you’re interested in trying melatonin, experts recommend starting with 0.5 to 1 mg about two hours before bedtime.
Cuban, like Dr. Anthony Fauci and biohacker Bryan Johnson, takes a vitamin D supplement every day.
Vitamin D is an essential vitamin that helps our body absorb calcium through food, which is necessary for building and maintaining strong healthy bones, especially as we age.
People typically get vitamin D through their diet or through sun exposure.
But older people, people who have more melanated skin, and people who live in climates with less sun are at greater risk of developing a vitamin D deficiency, according to Cleveland Clinic.
Cuban said that he started taking a vitamin D supplement after blood work revealed his vitamin D levels were low. And he isn’t alone — according to Cleveland Clinic, about 35% of adults in the United States have a vitamin D deficiency.
But now that he takes a vitamin D supplement, Cuban said his vitamin D levels are back in the desired range.

Cuban also said he takes vitamin E. Vitamin E is found in a variety of fruits, vegetables, nuts, seeds, and plant-based oils, and functions as an antioxidant.
While vitamin E deficiency is rare in the United States, according to Harvard Health, taking a vitamin E supplement may still have health benefits. Some evidence suggests that vitamin E supplementation could slow the aging process of cells, boost the immune system, and improve blood vessel health.
However, scientists at the US Preventive Services Task Force said in a 2022 statement that it does not recommend taking vitamin E to prevent cardiovascular disease or cancer.
