List of Supplements Mark Cuban Takes

The billionaire entrepreneur's minimalist, science-backed approach to daily supplementation for longevity and performance

Mark Cuban, the 66-year-old billionaire investor, Dallas Mavericks owner, and "Shark Tank" star, says 60 is the new 40 — and he credits simple daily habits for feeling decades younger. Among them? Just three carefully chosen supplements. Unlike many high-net-worth individuals who pile on dozens of pills, Cuban takes a minimalist, data-driven approach based on regular blood work rather than following wellness trends. In 2022, Cuban launched Mark Cuban Cost Plus Drug Company to make medications more affordable, bringing transparency to an industry notorious for opacity. Now he's sharing what he personally takes for optimal health: a straightforward stack focused on addressing specific deficiencies and supporting foundational wellness.

Key Takeaways

• Data-driven supplementation wins – Cuban bases his choices on blood tests conducted every 3-6 months, only supplementing what his body actually needs rather than following wellness fads

• Quality over quantity matters – Despite access to every supplement imaginable, Cuban takes just three: Vitamin D, melatonin, and Vitamin E, proving effective wellness doesn't require elaborate stacks

• Expert opinions vary widely – Registered Dietitian Shyla Cadogan states most Americans would benefit from only 1 of Cuban's 3 supplements (Vitamin D), highlighting the importance of individual assessment

• Vegetarian diets require attention – Since adopting a plant-based diet in 2019, Cuban's Vitamin D supplementation addresses common deficiencies in those with less animal product consumption

• Lifestyle provides the foundation – Cuban's supplement routine works alongside 45-90 minutes daily exercise and a whole-food vegetarian diet, not as a replacement for healthy habits

• Affordability is achievable – Cuban's entire supplement stack costs an estimated $10-30 monthly, demonstrating that longevity optimization doesn't require luxury pricing

Cuban's Core Supplement Stack

1. Vitamin D: Addressing a Documented Deficiency

Mark Cuban started taking Vitamin D after blood work revealed suboptimal levels, and his labs now show he's back in the desired range. This fat-soluble vitamin supports calcium absorption for bone health, immune system function, and may reduce certain cancer risks.

Why Vitamin D matters:

• Approximately 35% of US adults are deficient in Vitamin D, with 1 billion people worldwide affected according to Cleveland Clinic data

• Deficiency risk increases for individuals with melanated skin, those who spend limited time outdoors, and people living in northern climates

• Cuban's vegetarian diet since 2019 may contribute to lower levels, as the nutrient is more abundant in animal products like fatty fish, egg yolks, and fortified dairy

• The recommended daily value for adults aged 19-70 is 15 mcg (600 IU), though many practitioners recommend higher doses for documented deficiencies

Registered Dietitian Shyla Cadogan evaluated Cuban's supplement stack and concluded that Vitamin D stands out, stating: "Out of these options, however, most Americans would likely only benefit from 1 out of 3 — vitamin D." This expert validation underscores why data-driven supplementation through blood testing yields better outcomes than guessing or following trends. Cuban's approach — test, supplement what's deficient, retest to confirm — represents the gold standard for personalized nutrition.

For those looking to fill nutritional gaps beyond single vitamins, a comprehensive greens powder can provide a broader spectrum of plant-based nutrients including B-vitamins and Vitamin C, which work synergistically with Vitamin D for immune support and energy metabolism. XV1 Green Superfood Powder delivers organic greens, red antioxidants, and immune-supporting compounds in one daily scoop, with no sugar or fillers — a science-backed approach that complements targeted supplementation like Cuban's Vitamin D protocol.

2. Melatonin: Supporting Sleep and Circadian Rhythm

Mark Cuban takes melatonin every night to support his sleep cycle, a hormone naturally produced by the pineal gland that regulates the body's sleep-wake rhythm.

How melatonin works:

• Helps signal to the body that it's time to wind down for busy entrepreneurs managing multiple business ventures, travel schedules, and irregular hours

• A 2013 meta-analysis found melatonin supplementation helped people fall asleep approximately 7 minutes faster and sleep 8 minutes longer on average

• While improvements may seem modest, they can compound over weeks and months, contributing to better overall sleep quality

• Experts typically recommend supplemental doses of 0.5-1mg taken 2 hours before bedtime

Registered Dietitian Shyla Cadogan offers important context: "while some studies show that melatonin supplements can improve sleep in some cases, this isn't applicable to everyone" and points out quality concerns given limited supplement regulation. This underscores the importance of choosing third-party tested products with verified melatonin content.

Interestingly, Cadogan suggests that magnesium supplementation might prove beneficial for many individuals, as it addresses both sleep difficulties and common mineral deficiencies. For those seeking alternatives to melatonin or looking to support sleep quality through comprehensive nutritional support, addressing multiple pathways simultaneously — stress reduction, blood sugar balance, and micronutrient status — may yield better long-term results.

3. Vitamin E: Antioxidant and Immune Support

Vitamin E represents Cuban's third daily supplement. This fat-soluble antioxidant supports immune function, promotes healthy blood vessel function, and provides cellular protection against oxidative stress.

Vitamin E considerations:

• The U.S. Preventive Services Task Force issued a 2022 recommendation regarding Vitamin E supplementation for cardiovascular disease or cancer prevention in generally healthy adults

• Research shows mixed results, with some studies suggesting benefits while others indicate potential concerns at high doses

• As a fat-soluble vitamin, Vitamin E accumulates in body tissues rather than being readily excreted like water-soluble vitamins

• Vitamin E deficiency is rare in the United States, and Cuban's vegetarian diet rich in nuts, seeds, plant oils, avocado, and peanut butter naturally provides Vitamin E

Registered Dietitian Shyla Cadogan noted that Cuban could likely obtain Vitamin E benefits through food without supplementation. For those seeking comprehensive antioxidant protection, a broader approach targeting cellular health may prove effective. XV1 Glutathione Complex features liposomal glutathione — known as the "master antioxidant" — which supports natural detoxification, reduces oxidative stress, and promotes healthy aging with just one capsule daily. The formula is vegan, non-GMO, and gluten-free, with no sugar or fillers.

Supporting Optimal Health

Comprehensive Nutritional Foundation

While Cuban hasn't publicly disclosed taking a greens powder, his vegetarian diet since 2019 creates a strong foundation for understanding why comprehensive plant-based supplementation makes sense for busy executives. Whole food sources always provide the gold standard for nutrition, but achieving optimal micronutrient density from diet alone requires meticulous meal planning — challenging even for billionaires during travel and packed schedules.

Green superfood powders concentrate dozens of organic vegetables, fruits, and functional ingredients into a single serving, delivering phytonutrients, enzymes, and beneficial compounds. High-quality formulations include digestive enzymes to break down plant fibers and probiotic strains to support gut health, which directly influences nutrient absorption.

For someone like Cuban who exercises 45-90 minutes daily, antioxidant support becomes particularly relevant for managing exercise-induced oxidative stress and supporting recovery. XV1 Green Superfood Powder addresses these needs with organic greens, red antioxidants from superfruits, immune-supporting compounds, and an advanced probiotic blend with prebiotic fiber and digestive enzymes. The formula includes B-vitamins and Vitamin C that complement Cuban's Vitamin D supplementation, supporting energy metabolism without caffeine.

Longevity and Cellular Health

Resveratrol, a polyphenol antioxidant found in grape skins and Japanese knotweed, has gained attention for potential cardiovascular and cognitive benefits. The compound crosses the blood-brain barrier and activates SIRT1, a gene associated with longevity pathways. Research suggests resveratrol supports endothelial function — the health of blood vessel linings — which directly impacts circulation and cardiovascular wellness.

For executives concerned with maintaining cognitive sharpness and cardiovascular health as they age, resveratrol represents a research-backed option with a strong safety profile. The antioxidant properties help combat oxidative stress, a key driver of cellular aging. XV1 RESVERATROL provides 98% pure trans-resveratrol derived from Polygonum cuspidatum, third-party tested and manufactured in FDA-registered facilities. The formula supports cardiovascular health, promotes healthy aging, and enhances brain function with just 1 capsule daily.

Building Your Science-Backed Stack

Creating an effective supplement protocol requires understanding nutrient timing and synergies. Fat-soluble vitamins (A, D, E, K) absorb best when taken with meals containing dietary fat, while water-soluble vitamins (B-complex, C) can be taken anytime.

Start with blood work to identify actual deficiencies. Cuban's approach of testing every 3-6 months provides objective data to guide decisions. Common tests include comprehensive metabolic panels, lipid panels, Vitamin D (25-hydroxyvitamin D), B12, iron/ferritin, and thyroid function.

Quality markers include third-party testing certifications (NSF, USP), transparent label disclosure, manufacturing in cGMP facilities, and absence of unnecessary fillers. Cuban's stack costs an estimated $10-30 monthly, proving effective supplementation doesn't require luxury pricing.

Gender-Specific Considerations

While Cuban's routine provides a useful framework, women have distinct nutritional needs. Iron requirements differ significantly, with premenopausal women needing 18 mg daily compared to 8 mg for men. Many women also require higher calcium intake to support bone density, particularly approaching menopause.

Folate (Vitamin B9) becomes critically important for women of reproductive age. The CDC recommends 400 mcg daily for all women capable of becoming pregnant. Vitamin D and omega-3 fatty acids support hormonal balance and reduce inflammation.

For women seeking comprehensive nutritional support, XV1 Green Superfood Powder delivers B-vitamins, Vitamin C, and nutrient-dense organic greens supporting energy, immune function, and overall vitality in one daily scoop. While it doesn't replace targeted supplementation for specific deficiencies, it provides a strong foundation for women's health when combined with individualized supplement choices.

Frequently Asked Questions

What supplements does Mark Cuban take every day?

Mark Cuban takes three supplements daily: Vitamin D (started after blood work revealed deficiency), melatonin every night for sleep support, and Vitamin E for antioxidant protection. His minimalist approach focuses on addressing specific needs through blood testing rather than taking dozens of pills based on trends.

How does Cuban decide which supplements to take?

Cuban bases all supplement decisions on blood work conducted every 3-6 months. He only supplements what testing shows his body actually needs, stating "that's helped me learn a lot about my body. I just try to be smart." This data-driven approach prevents unnecessary supplementation and tracks whether protocols actually work.

Should I take a multivitamin or individual supplements?

This depends on your diet quality, lifestyle, and individual deficiencies revealed through blood testing. Multivitamins provide broad-spectrum coverage and convenience but may contain nutrients you don't need while potentially undersupplying those you do. Individual supplements allow targeted dosing for specific deficiencies but require more research and planning. Mark Cuban's approach suggests starting with blood work, then supplementing only what's actually low.

Can women and men use the same supplement stack?

While many supplements work for both genders, women often need more iron (particularly premenopausal), additional folate if of reproductive age, and potentially different calcium amounts for bone health. Men and postmenopausal women typically need less iron. However, foundations like Vitamin D, B-vitamins, and antioxidants benefit everyone. Blood testing reveals individual needs better than gender-based generalizations.

How long does it take to see results from supplements?

The timeline varies by supplement and individual. Vitamin D levels typically normalize within 2-3 months of consistent supplementation. Melatonin effects on sleep may be noticed within days to weeks. The key is consistency and retesting — Cuban's approach of testing every 3-6 months allows tracking actual progress rather than guessing at effectiveness.
