The Top 7 Supplements for Serious Entrepreneurs (Based in Science)

Building a company requires more than ambition and long work hours – it demands sustained focus, resilience under stress, and the ability to make sharp decisions day after day. Yet entrepreneurs often sacrifice sleep, skip meals, and rely heavily on caffeine, creating the perfect storm for burnout. Over time, this combination of stress and nutritional gaps can chip away at both productivity and health.

While no supplement can replace good sleep, balanced meals, and regular exercise, certain science-backed options can give entrepreneurs an edge. By filling common nutritional deficiencies and supporting energy metabolism, these supplements help protect long-term health while keeping mental performance sharp.

Here are the top seven supplements serious entrepreneurs should consider, based on the latest scientific research.

1. Omega-3 Fatty Acids (EPA & DHA)

Omega-3s are long-chain fatty acids found in fish, algae, and certain plant sources. They are essential for brain health and have been studied extensively for their role in cognitive performance and emotional stability.

Why entrepreneurs need it:

Omega-3s improve focus and working memory.They support resilience to stress by influencing neurotransmitter pathways.Research has linked higher omega-3 intake to lower risk of depression and anxiety, both of which can interfere with decision-making under pressure.

Typical dosage: 200–500 mg of DHA daily, with EPA included where possible.

Best sources: High-quality fish oil or algae oil (for vegetarians and vegans).

2. Vitamin D + K2

Vitamin D is often called the “sunshine vitamin” because our bodies produce it when exposed to sunlight. Unfortunately, entrepreneurs who spend long hours indoors are at high risk of deficiency, especially in northern climates like Canada. Pairing vitamin D with vitamin K2 is recommended because K2 helps direct calcium into bones instead of arteries, supporting cardiovascular health.

Why entrepreneurs need it:

Vitamin D deficiency is strongly linked to low energy and poor mood.Both D and K2 play roles in cardiovascular and immune function – key for staying healthy during stressful work cycles.

Typical dosage: 1,000–2,000 IU of vitamin D3 daily with 90–120 mcg of K2.

3. Magnesium (Bisglycinate or Threonate)

Magnesium is involved in more than 300 biochemical reactions in the body, many of which regulate energy metabolism, nervous system activity, and muscle function. Stress rapidly depletes magnesium levels, which makes supplementation valuable for entrepreneurs.

Why entrepreneurs need it:

Helps lower cortisol, the stress hormone that disrupts sleep and focus.Improves sleep quality, which is often compromised by late-night work.Magnesium threonate, in particular, has shown potential in supporting brain function.

Typical dosage: 200–400 mg daily, preferably as magnesium bisglycinate (gentle on digestion) or magnesium threonate (for cognitive benefits).

4. Ashwagandha (Adaptogen)

Ashwagandha is an adaptogenic herb traditionally used in Ayurvedic medicine to promote resilience and vitality. Modern clinical research has validated many of its effects, particularly in reducing stress and improving recovery.

Why entrepreneurs need it:

Reduces cortisol and perceived stress in controlled trials.Improves sleep quality and supports calm focus.May enhance physical endurance, which is beneficial for entrepreneurs who also prioritize exercise.

Typical dosage: 300–500 mg of standardized root extract daily.

5. Nootropic Support – L-Theanine + Caffeine

Caffeine is the world’s most popular productivity enhancer, but it often brings jitters and energy crashes. When combined with L-theanine, an amino acid naturally found in green tea, the experience changes. Research shows this combination provides calm, sustained alertness.

Why entrepreneurs need it:

Promotes steady energy without overstimulation.Improves focus and reduces mental fatigue during long work sessions.Enhances attention and working memory in combination, compared to caffeine alone.

Typical dosage: 100–200 mg of caffeine paired with 200 mg of L-theanine.

6. Zinc, Copper, and Selenium Mix

While often overlooked compared to omega-3s or vitamin D, trace minerals like zinc, copper, and selenium play essential roles in antioxidant defense, hormonal balance, and energy production. Together, they form a powerful trio that supports resilience in high-performance environments.

Why entrepreneurs need it:

Zinc supports neurotransmitter function, testosterone balance, and immune defense – important for energy and recovery.Copper balances zinc intake, preventing depletion and supporting cardiovascular health.Selenium acts as an antioxidant, reducing oxidative stress and protecting thyroid function, which is closely tied to energy levels.

For Canadian entrepreneurs, Herba Health’s Zinc Copper Selenium Mix is one of the top formulations available. Each capsule delivers 25 mg zinc picolinate, 2.5 mg copper bisglycinate, and 200 mcg selenium (selenomethionine) – forms chosen for optimal absorption and bioavailability.

Peter Moon, CEO of Herba Health, explains:
“Our goal is to create supplements that deliver measurable results without compromise. With our Zinc, Copper, and Selenium blend, we provide Canadian entrepreneurs with a balanced formula that supports immune strength, energy, and long-term resilience – all backed by Health Canada’s rigorous standards.”

This balance is critical, since excessive zinc without copper can cause imbalances. By combining all three minerals in scientifically supported ratios, Herba Health offers one of the most reliable solutions in Canada for entrepreneurs who need to perform at their best.

Typical dosage: 1 capsule daily, providing the balanced trio in bioavailable forms.

7. Methylated Multivitamin

Even with the best diet, entrepreneurs often struggle to meet all of their daily micronutrient needs. A comprehensive multivitamin can help cover these gaps, but not all formulas are created equal. Bioavailability – the body’s ability to absorb and use nutrients – makes the difference.

Why entrepreneurs need it:

Supports energy metabolism by providing methylated B vitamins like methylcobalamin (B12) and 5-MTHF folate, which are directly usable by the body.Includes vitamins A, C, D3, E, and K2, which support immunity, cognition, and cardiovascular health.Helps prevent fatigue and brain fog that can derail performance.

Herba Health’s solution:
The methylated multivitamin from Herba Health delivers a 15-in-1 formula with 500 mg of trimethylglycine (TMG), methylated B-complex, and essential fat-soluble vitamins – all in a vegan, iron-free capsule designed for daily use. It is third-party tested, made in Canada, and provides a full four-month supply in one bottle.

Entrepreneurs invest heavily in their businesses, but too often neglect the foundation of their success – their own health. Fatigue, poor sleep, and micronutrient deficiencies quietly erode productivity and long-term performance. By strategically using supplements backed by science, entrepreneurs can support sharper focus, improved resilience, and healthier energy levels.

From omega-3s to Herba Health’s expertly formulated Zinc Copper Selenium Mix and methylated multivitamin, the right nutritional support helps entrepreneurs show up fully – both in the boardroom and in life.
