Which of the following is listed as a key therapeutic nutrient for angina?

• A. CoQ10
• B. Vitamin D
• C. Zinc
• D. Glutamine

Answer: (A)

CoQ10 supports the heart’s energy production and antioxidant defenses, which is why it’s highlighted for angina. In heart muscle, ATP production relies on mitochondrial function, and CoQ10 is a crucial cofactor in the electron transport chain, helping convert fats and sugars into usable energy. When the heart isn’t getting enough oxygen, efficient energy generation becomes even more important, so supplemental CoQ10 can help improve myocardial energy efficiency and may reduce the frequency and severity of anginal episodes and improve exercise tolerance in some people. Its antioxidant action also helps protect heart cells from ischemia-related stress. Additionally, many patients with angina take statins, which can lower endogenous CoQ10, making supplementation particularly relevant. CoQ10 is generally well tolerated but can interact with certain medications such as anticoagulants, so it’s best used under supervision. Other nutrients like Vitamin D, zinc, and glutamine contribute to overall health but don’t have the same direct, evidence-supported role in managing angina, which is why CoQ10 is considered the key therapeutic nutrient in this context.
