The Heart

Supporting One of the Body's Most Important Organs

Your heart works every second of every day, pumping blood through thousands of kilometres of blood vessels to deliver oxygen and nutrients to every cell in your body. It never takes a day off, making it one of the hardest-working organs you have.

Learning how to support your heart through nutrition, lifestyle, and informed choices can help maintain cardiovascular health throughout life. While genetics, age, and medical conditions all play a role, the nutrients and plant compounds we consume every day provide the building blocks the heart needs for normal function, maintenance, and repair.

The Wellness Profiles are designed to help you understand these relationships by bringing together research on vitamins, minerals, plant compounds, and plants that naturally contain them. Rather than focusing on a single "superfood," the goal is to help you discover how many different nutrients work together to support overall wellness.

What Does the Heart Do?

The heart is a powerful muscle that:

• Pumps oxygen-rich blood throughout the body.
• Delivers nutrients to tissues and organs.
• Removes carbon dioxide and metabolic waste.
• Maintains blood pressure.
• Supports circulation.
• Helps transport hormones and immune cells.
• Responds to physical activity, stress, and rest.

Healthy heart function depends on healthy muscles, nerves, blood vessels, connective tissue, and proper electrical signalling.

Vitamins Important for Heart Health

Vitamin A

Supports healthy blood vessel tissues and immune function while helping maintain the cells that line the cardiovascular system.

Vitamin B1 (Thiamine)

Essential for converting food into energy. Since the heart requires a constant supply of energy, adequate thiamine is critical for normal heart muscle function.

Vitamin B2 (Riboflavin)

Supports energy production inside heart cells and contributes to antioxidant protection.

Vitamin B3 (Niacin)

Supports normal energy metabolism and contributes to healthy circulation.

Vitamin B5 (Pantothenic Acid)

Required for the production of Coenzyme A, which plays a major role in energy production within heart muscle cells.

Vitamin B6

Supports healthy homocysteine metabolism, nervous system function, and red blood cell production.

Vitamin B7 (Biotin)

Supports energy metabolism and healthy cellular function.

Vitamin B9 (Folate)

Works with Vitamin B12 and B6 to help regulate homocysteine levels while supporting healthy blood formation.

Vitamin B12

Essential for red blood cell formation, oxygen transport, nerve function, and cardiovascular health.

Vitamin C

An important antioxidant that supports collagen production, helping maintain healthy blood vessels while protecting tissues from oxidative stress.

Vitamin D

Supports normal muscle function, including the heart muscle, while working alongside calcium and magnesium.

Vitamin E

Protects cell membranes from oxidative damage and supports healthy circulation.

Vitamin K

Supports normal blood clotting and helps regulate calcium placement within the body, contributing to healthy arteries.

Minerals Important for Heart Health

Magnesium

One of the most important minerals for the heart.

Magnesium supports:

• Normal heartbeat
• Muscle relaxation
• Electrical signalling
• Blood vessel function
• Energy production

Many people do not consume adequate magnesium.

Potassium

Works closely with sodium to maintain:

• Healthy blood pressure
• Fluid balance
• Nerve signalling
• Muscle contractions
• Normal heart rhythm

Calcium

Required for proper muscle contraction, including every heartbeat.

Balance with magnesium and Vitamin D is essential.

Sodium

Although excessive sodium can contribute to high blood pressure in many individuals, sodium remains an essential mineral required for fluid balance, nerve signalling, and muscle contraction. The goal is balance rather than elimination.

Phosphorus

Supports cellular energy production (ATP), which powers every heartbeat.

Iron

Allows red blood cells to carry oxygen to heart tissue and the rest of the body.

Zinc

Supports tissue repair, immune function, antioxidant activity, and enzyme production.

Copper

Works with iron to support healthy blood vessels and connective tissues.

Manganese

Supports antioxidant enzymes and healthy connective tissue formation.

Plant Compounds That Support Heart Wellness

Plants naturally produce thousands of beneficial compounds that help protect both the plant and those who consume them.

Polyphenols

Support antioxidant protection and healthy blood vessel function.

Examples:

• Berries
• Grapes
• Apples
• Green tea

Flavonoids

Associated with healthy circulation and vascular function.

Examples:

• Blueberries
• Onions
• Parsley
• Citrus fruits

Carotenoids

Provide antioxidant protection that helps protect heart tissues.

Examples:

• Beta-carotene
• Lycopene
• Lutein

Organosulfur Compounds

Found in garlic and other allium vegetables, these compounds have been widely studied for their role in supporting cardiovascular health.

Polysaccharides

Support immune function and healthy gut microbiota, which increasingly appears connected to cardiovascular health.

Beta-Glucans

Naturally found in oats and mushrooms and known for supporting healthy cholesterol levels already within the normal range as part of a healthy diet.

Terpenoids

Many herbs rich in terpenoids also provide antioxidant and anti-inflammatory properties.

Capsaicin

The compound responsible for the heat in peppers has been studied for its effects on circulation, metabolism, and cardiovascular health.

Ontario Plants That Can Support Heart Wellness

Many plants that grow naturally in Ontario contain nutrients and beneficial plant compounds.

Examples include:

• Dandelion
• Stinging Nettle
• Red Clover
• Plantain
• Wild Strawberry Leaves
• Raspberry Leaves
• Goldenrod
• Elderberry
• Hawthorn (berries and flowers)
• Peppermint
• Basil
• Mullein

These plants contribute different combinations of vitamins, minerals, antioxidants, and plant compounds.

Excellent Indoor Plants for Heart Wellness

Several nutrient-rich plants grow well indoors year-round in small containers or simple hydroponic systems.

Excellent choices include:

• Basil
• Peppermint
• Dandelion
• Plantain
• Hot Peppers
• Parsley
• Leaf Lettuce
• Kale
• Spinach

Growing even a few plants indoors can provide a fresh source of nutrients while encouraging a stronger connection with the food you eat.

Heart Wellness Is About the Whole Body

No single vitamin, mineral, herb, or plant compound keeps the heart healthy on its own.

Heart health depends on the interaction of:

• Nutritious foods
• Physical activity
• Healthy sleep
• Stress management
• Maintaining a healthy weight
• Avoiding tobacco
• Managing chronic conditions
• Regular medical care when needed

Nutrition provides the foundation that allows these systems to work together.

Continue Your Wellness Journey

The Heart Wellness Profile is one part of the Wellness Profiles, where each vitamin, mineral, plant compound, and body system is explored in greater depth.

As you continue learning, you'll discover how nutrients work together rather than independently, why growing even a few plants at home can improve access to fresh nutrition, and how understanding your body's needs can help you make informed choices that support long-term health.
