Folate (L-5-MTHF) “Support your heart naturally with Cardio Strong, a comprehensive cardiovascular wellness formula developed by Dr. Thomas O’Connor — The Trusted Doc — to promote optimal heart function, balanced circulation, and long-term vitality. Drawing on both time-tested herbal traditions and modern clinical research, Dr. O’Connor formulated Cardio Strong to give you complete, daily support for a healthy, energized cardiovascular system.
At the foundation of Cardio Strong is Arjuna, a revered Ayurvedic heart tonic known for strengthening heart muscles and supporting healthy blood pressure. Paired with Hawthorn berry, a botanical widely recognized for enhancing circulation and protecting the heart from oxidative stress, this powerful duo helps maintain steady heart rhythm, endurance, and overall cardiac resilience — reflecting Dr. O’Connor’s commitment to high-impact, natural heart support.
To further reinforce vascular health and cholesterol balance, Olive Leaf Extract and Quercetin provide potent antioxidant and anti-inflammatory benefits. Olive leaf promotes healthy arterial function, while quercetin helps reduce oxidative damage to blood vessels, encouraging smooth circulation and long-term vascular integrity.
For advanced arterial protection, Red Wine Concentrate delivers natural polyphenols that work synergistically with Lycopene (Lyc-O-Mato®), a clinically researched antioxidant derived from tomatoes. Together, these ingredients help protect arteries from free radical damage, support healthy cholesterol levels, and maintain arterial elasticity for optimal blood flow — a key focus in Dr. O’Connor’s cardiovascular wellness philosophy.
To support energy, red blood cell production, and metabolic heart health, the formula includes Folate (L-5-MTHF) and Vitamin B12, essential nutrients involved in homocysteine metabolism and cellular vitality.
Rounding out this comprehensive blend is Trikatu, an Ayurvedic combination of Long Pepper Fruit, Ginger Rhizome, and Black Pepper Fruit. Known for enhancing digestion and nutrient absorption, Trikatu ensures your body receives maximum benefit from every capsule while also supporting healthy metabolism and circulation.
Expertly formulated by Dr. Thomas O’Connor — The Trusted Doc, Cardio Strong combines natural herbal extracts with clinically backed nutrients to deliver complete heart and circulatory support. This daily formula helps you maintain energy, endurance, and cardiovascular wellness as you age — backed by a doctor dedicated to your long-term health.”
