Supplements for the heart and circulatory system include omega-3, CoQ10, magnesium, garlic, plant sterols and other ingredients. They do not replace medical monitoring, blood pressure or lipid management, or medication when needed.
Heart & Circulatory Support – The basic principles
What affects cardiovascular health most?
- diet
- physical activity
- blood pressure
- blood lipids
- smoking
- body weight and metabolic health
Omega-3 – EPA & DHA
What is their role?
EPA and DHA are omega-3 fatty acids with important physiological roles. A fish-oil product should be assessed by its actual mg of EPA + DHA, rather than just its total mg of fish oil.
CoQ10
What is it?
Coenzyme Q10 is involved in mitochondrial energy production and is used in some cardiovascular formulas. It is not a substitute for medications.
Magnesium & Potassium
Magnesium
Magnesium is involved in normal muscle and nerve function and electrolyte balance.
Potassium
Potassium is important for normal cell and muscle function. High-dose potassium supplements should not be used indiscriminately, particularly in people with kidney problems or taking certain medications.
Garlic Extract
Garlic extract has been studied in relation to certain cardiovascular markers. Different extracts are not equivalent and may affect clotting.
Plant Sterols
Plant sterols / stanols are used in some foods and supplements to support LDL cholesterol management. Their use should form part of an overall dietary strategy.
Beetroot & Nitrates
Beetroot provides dietary nitrates, which are associated with nitric oxide pathways and mainly used for exercise performance and vascular function.
Citrulline & Arginine
Citrulline and arginine are used in pump formulas because of their relationship with nitric oxide metabolism. They are not treatments for vascular diseases.
How to read a Heart Support Formula
- EPA + DHA per dose
- CoQ10 per dose
- the form and amount of magnesium
- herbal extracts and standardisation
- potential interactions with anticoagulants or antihypertensives
Frequently Asked Questions
1. Does a supplement lower cholesterol on its own?
Not in the sense of replacing diet, medical assessment or medications.
2. Are fish oil and omega-3 the same?
Fish oil is a source of omega-3, but what matters most is the EPA and DHA content.
3. Can I take garlic and fish oil with anticoagulants?
Professional advice is needed because the risk of interactions may increase.
In Brief
Cardiovascular support starts with lifestyle and medical monitoring. Supplements are additional tools, rather than treatments.
