Top Nutrients for Heart Health

Collectively, conditions affecting the heart are the UK’s biggest killer. Almost 2.3 million people live with coronary heart disease (CHD), leading to annual NHS healthcare costs of almost £2 billion. Key risk factors for heart disease affect large proportions of the adult population – one third of adults have high blood pressure while 60% have sub-optimal blood cholesterol levels. Despite these alarming figures, many risk factors are within our control and making simple changes to our diet and lifestyle can have a dramatic impact on our health. As we mark National Heart month we turn our attention to key nutrients and nutrition supplements that play a strong role in maintaining a heart-healthy lifestyle.

ALA Omega-3

Alpha-linolenic acid (ALA) is a type of omega-3 essential fatty acid (or ‘good’ polyunsaturated fat) that has been shown over years of research to help maintain normal cholesterol levels. Although cholesterol is a vital resource in the body, helping to carry out a number of important functions such as repairing blood vessels, creating hormones, production of vitamin D, and helping to transport vitamins A, D, E & K, it can become a risk when levels of LDL ‘bad’ cholesterol become too high. This can trigger a build-up of plaque in the arteries, which can eventually

lead to heart attacks and strokes.

Dual cholesterol protection

Despite popular belief, only 20% of the cholesterol in our body comes from our diet whereas the majority, the remaining 80%, is produced by our own cells, mainly in the liver. ALA directly reduces production of cholesterol in the liver at its source, which is a highly effective way of normalising cholesterol levels.

ALA is also well known for reducing inflammation in the body, which helps to slow down plaque build-up in the arteries. Taking ALA daily is a great way to favourably balance the ratio of ‘good’ to ‘bad’ fats consumed in the diet.

Ubiquinol CoQ10

Coenzyme Q10 (CoQ10) is a naturally occurring enzyme with a multitude of roles in the cardiovascular system. CoQ10 acts within our cells in the mitochondria, the body’s energy ‘powerhouse’. Maintaining healthy CoQ10 levels fuels the mitochondria and supports the high energy requirements of our organs, particularly the heart. In addition to energy production, CoQ10 plays a vital role in oxygen utilisation to further support the functioning of heart muscle cells and maintain good circulatory health. CoQ10 also helps to lower blood pressure and is recognised as an effective cholesterol lowering ‘agent’.

Research studies show that people with cardiovascular problems often have low levels of CoQ10. Risk of deficiency is even higher with patients taking statins to lower cholesterol, since not only are they likely to have low levels of CoQ10 but statins also block natural ubiquinol synthesis in the body.

Ubiquinol versus Ubiquinone

There are two types of CoQ10 used in supplements: ubiquinone and ubiquinol. Ubiquinol is ‘body-ready’, which means the body doesn’t have to convert it into a usable form – a therapeutic advantage over ubiquinone. As an antioxidant, ubiquinol also offers protection against arterial plaque, thereby reducing heart attack risk and safeguarding heart muscle cells from free radical damage. Uniquely, ubiquinol also regenerates other beneficial antioxidants such as vitamins C and E.

Ubiquinone versus ubiquinol is just half the battle with CoQ10; addressing bioavailability is a further challenge, since therapeutic outcomes are achieved by raising blood plasma levels. Most ubiquinol supplements are oil-based, which means that large ubiquinol particles struggle to pass through the gut’s water layer barrier and are poorly absorbed. A special patented delivery system called VESIsorb®, utilised by CoQ10 manufacturer Igennus, optimises absorption by converting ubiquinol into water-soluble particles, ‘pre-digesting’ it so ubiquinol is effectively fast-tracked through the digestive system. VESIsorb delivers ubiquinol into the blood stream 2 times faster than standard oil-based forms, increasing tissue distribution throughout the body to achieve significantly higher blood concentrations that remain at therapeutic levels for up to 6 times longer.

Live cultures

Three specific live cultures L. plantarum CECT 7527, 7528 and 7529, help break down bile salts, which are made from cholesterol, therefore allowing its removal from the body. These friendly bacteria also metabolise dietary cholesterol in the gut, therefore reducing its absorption into the bloodstream. The AB-LIFE strains also produce a beneficial short-chain fatty acid known as propionic acid, which signals the liver to produce less cholesterol and also has an anti-inflammatory effect.

Top heart health supplements

A new and unique formula from OptiBac Probiotics is the first of its kind formulated for heart health. For your cholesterol is a pioneering, well researched multi-targeted natural supplement that combines unique live cultures with omega-3 ALA from cold-pressed virgin flaxseed oil – offering a multitude of benefits for managing healthy cholesterol levels.

Since not all live cultures are the same, OptiBac Probiotics focuses on specific strains of natural bacteria that have been clinically tested and proven to survive stomach acidity, bile salts and digestive enzymes in order to find the best live cultures for the job.

VESIsorb® Ubiquinol-QH from Igennus provides 100 mg of fast-acting body-ready ubiquinol CoQ10 for optimal therapeutic benefits. Taken daily, this advanced supplement offers comprehensive cardiovascular support, providing potent antioxidant activity and maximal energy production.

National Cholesterol Week

This week is National Cholesterol Week, HEART UK’s annual event to raise awareness of the dangers of high cholesterol. Heart disease is the UK’s biggest killer, accounting for around a quarter of all deaths. The good news is that if you have raised cholesterol alongside other markers of heart disease, it can in almost every case be reversed through dietary and lifestyle measures.

Cholesterol is a fatty substance manufactured by the liver and it plays an important role in your body. It is a component in the membrane of every cell in your body. It is also involved in hormone production and helps the nervous system to function properly. When there is inflammation or damaged tissue in the body, cholesterol can accumulate in the areas in need of healing. This may be why raised cholesterol can signify damage in your arteries. LDL or ‘bad’ cholesterol is a particular concern because this type of cholesterol can become oxidised, leading to tissue damage and hardening of the arteries.

There are three cholesterol readings that you can have. Total cholesterol, LDL (‘bad’) cholesterol and HDL (‘good’) cholesterol. LDL transports cholesterol from the liver through the bloodstream to sites where it is needed. HDL then transports it back again, and so HDL removes unwanted or damaged cholesterol from your arteries. Ideally HDL should make up at least a third of your total cholesterol.

While cholesterol is used as a marker for heart disease, in order to get a clearer idea of your real risk, it’s important to consider this marker alongside other markers such as levels of triglycerides, blood pressure and homocysteine.

If you eat a diet high in sugar and refined carbohydrates and fried foods, and low in protective fruits and vegetables, then cholesterol is likely to become damaged by oxidation. This type of diet also provides very little soluble fibre which is essential in eliminating excess cholesterol. In general, the best diet for lowering LDL cholesterol is a low GI diet. This type of diet has been found to be particularly effective in reducing LDL and triglycerides and raising HDL (1). A huge benefit of a low GI diet is that it has greater levels of soluble fibre which helps to remove LDL cholesterol from the body. It also provides plenty of antioxidants, helping to combat oxidative damage.

Here are 10 simple ways to reduce your cholesterol level, improve your lipid profile and lower your overall risk of heart disease.

Lettuce
Leafy Greens boost magnesium, helping to relax your arteries.

1. Increase leafy greens and add raw nuts and seeds to your diet.
These boost magnesium, helping to relax your arteries.

2. Drink 8 glasses of water each day.
Proper hydration reduces blood pressure by lowering levels of sodium inside cells.

3. Reduce your salt intake.
Reducing sodium levels can help to relax the arteries.

4. Add plant sterols.
Plant sterols lower ‘bad’ cholesterol by blocking its absorption. They are present in soya beans, lentils, nuts and seeds.

5. Increase low GI carbohydrates.
Soluble fibre, in oats, lentils, beans and vegetables, helps to reduce levels of ‘bad’ cholesterol. Beta-glucans in oats are particularly beneficial.

6. Add antioxidant-rich foods every day.
Antioxidants ‘mop up’ damage within the arteries. Try blueberries, strawberries, plums, tenderstem broccoli and spinach.

7. Boost your omega-3 intake with oily fish, flaxseed oil or omega-3 eggs.
Omega-3 fats help to lower triglycerides, lower ‘bad’ cholesterol and increase ‘good’ cholesterol.

8. Add garlic, ginger and turmeric to your cooking.
Garlic promotes healthy blood pressure, cholesterol and triglyceride levels. Turmeric and ginger help to relax the arteries.

9. Consider supplementing Co-Q10 and Vitamin C.
These nutrients reduce damage in the arteries and lower blood pressure.

10. Boost your B Vitamins.
Homocysteine is actually one of the strongest predictors of heart disease (2), damaging the lining of the arteries, but B vitamins convert it into a harmless substance. If you have raised homocysteine levels, then supplementing with B Vitamins can help. Try foods rich in folic acid such as broccoli, asparagus and spinach.

The role of omega-3 in heart health

Deaths caused by cardiovascular disease are generally premature and could easily, in some cases, be prevented by making lifestyle changes that include adopting a healthy lifestyle and increasing physical activity.

The role of lipid lowering (cholesterol and triglyceride) in reducing the risk of mortality and morbidity from cardiovascular disease is well documented. The cardiovascular benefits of omega-3, certainly in terms of cholesterol and triglyceride management, are probably the most researched of all the dietary nutrients known to influence cardiovascular disease risk. With the recent approval of the use of pure eicosapentaenoic acid (EPA) as a prescription treatment for hypertriglyceridemia [1] and with overwhelming evidence for EPA’s role over docosahexaenoic acid (DHA) in cholesterol management, [2] consumers should be aware of the differential effects of the two main omega-3s, EPA and DHA, on cardiovascular disease risk factors and why they should choose isolated EPA over generic fish oil.

EPA and lipid management

Whilst fish oil provides a convenient dietary intervention for maintaining heart health, the differential effects of the two main long-chain omega-3s, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on cardiovascular disease risk factors means that not all fish oil products are equal in their action.

Firstly, generic oils generally contain around 30% total omega-3 and are therefore not considered viable as a therapeutic. For example, the optimal triglyceride-lowering doses of omega-3 are 3-4g/day, with little evidence to support lipid-altering efficacy in doses of less than 1g/day. [3] In addition to providing a soluble means for transporting cholesterol and triglycerides through the blood, lipoproteins have cell-targeting signals that direct the lipids they carry to certain tissues.

Pharmepa Step 1: Restore (E-EPA 90) contains the purest ethyl-EPA concentrate available without prescription

Whilst high density lipoproteins (HDL) correlate with better health outcomes, effectively clearing cholesterol from the system, low density lipoproteins (LDL) are, in contrast, considered the cholesterol ‘bad boy’ and are responsible for the detrimental effects associated with total cholesterol.

Both EPA and DHA decrease triglyceride levels, and whilst EPA lowers LDL levels, DHA appears to increase LDL levels [4, 5]. Given that products that contain a mixture of EPA and DHA may increase LDL levels, the benefits of a pure EPA product understandably extend to both cholesterol and triglyceride management. Indeed, the cholesterol-lowering ability of pure EPA at a dose of 1.8 grams in a study of approximately 19,000 statin-treated patients with hypercholesterolaemia was shown to reduce the 5-year cumulative risk of major coronary events by 19%. Igennus’ Pharmepa Step 1: Restore (E-EPA 90) contains the purest ethyl-EPA concentrate available (90%) without prescription, delivers 1g pure EPA in just two easy-to-swallow capsules, and is ideal for those individuals wanting to manage cholesterol and triglyceride levels.

AA to EPA ratio and cardiovascular health

In addition to altering lipid metabolism, omega-3 may also improve cardiovascular health by inhibiting inflammatory products derived from the key pro-inflammatory fatty acid arachidonic acid (AA). AA and EPA are converted through phospholipase A2, cyclooxygenase (COX) and lipooxygenase (LOX) to prostaglandins, thromboxanes and leukotrienes, as well as various hydroxyl-fatty acids, and the AA to EPA ratio provides an established risk factor for numerous inflammatory-related conditions, including poor cardiovascular health. Indeed, inflammation is an important process in the development of cardiovascular disease; chronic inflammation, characterised by elevated plasma levels of inflammatory markers such as C-reactive protein (CRP) and IL-6, are commonly found in subjects at high cardiovascular risk, including type2 diabetics and patients with coronary heart disease. [6] Supplementing with EPA, in addition to triglyceride and cholesterol improvement, increases EPA blood levels, improves the AA to EPA ratio (which directly correlates with changes in improved LDL levels) and reduces cardiovascular related inflammation. [7]

In summary, EPA, unlike DHA, lowers levels of triglyceride, lowers ‘bad’ cholesterol and increases ‘good’ cholesterol, whilst reducing inflammation via management of the AA to EPA ratio. By providing pure isolated EPA at the concentrations required for therapeutic outcomes, Igennus’ Pharmepa range of EPA products are ideal health supplements for managing optimal heart health by managing lipid levels and modulating dysregulated inflammation. The prescription-strength ethyl-EPA Pharmepa Restore & MaintainTM  protocol is an innovative two-step treatment programme formulated to re-establish a healthy inflammatory status within the body. Step 1 counteracts an unhealthy AA to EPA ratio – the direct measure of inflammatory status, and step 2 ensures long-term balance for optimal cardiovascular health benefits.

Can CoEnzyme-Q10 combat statin side-effects?

A new study (1) confirms long-standing concerns about the side-effects of cholesterol-lowering statins. The study suggests that statin drugs can cause significant problems with energy levels and general fatigue, especially in women.

Statins are routinely prescribed to individuals with raised cholesterol levels and are among the most widely prescribed drugs in the UK. These drugs lower cholesterol levels by inhibiting a liver enzyme (HMG-CoA reductase) which plays a role in cholesterol production. Unfortunately this enzyme is also important for the production of Co-enzyme Q10. CoQ10 is a nutrient found in almost every cell in the body and is essential for energy production in the muscles.

The study, published in Archives of Internal Medicine, followed a group of individuals who were randomised to take one of two statins (simvastatin at 20 mg per day or pravastatin at 40 mg per day) or placebo for six months. Participants were rated at regular intervals through the study for their perceived fatigue on exertion, general fatigue and energy levels.

Overall, statins did indeed appear to cause a significant change in energy and worsen fatigue on exertion. Women were more affected than men.

In fact, 40% of the women receiving statins reported either a reduction in energy or a worsening of fatigue on exertion. 10% of the women reported that both of these issues were ‘much worse’.

Nuts contain CoQ10
Nuts contain Co-Enzyme Q10 (CoQ10) which is beneficial towards energy levels

Co-enzyme Q10 is essential for the ‘battery’ in each cell to power our muscles and organs. It is not surprising that depletion of CoQ10 can cause muscle weakness and fatigue. CoQ10 is also vital for heart function. According to one recent study (2), 71% of healthy people develop heart rhythm abnormalities when given statins.

It is important for those taking statins to be aware of the side-effects such as fatigue and muscle weakness, as these symptoms may only appear after some months or years after beginning statin treatment.

The good news is that those taking statins may be able to protect themselves from these side-effects by including good sources of CoQ10 in their diet. The richest dietary sources of this nutrient are organ meats such as liver and kidney, as these are the bodily organs that naturally store high levels of CoQ10. Other sources include oily fish, eggs, nuts and spinach.

For many individuals, dietary sources of CoQ10 may be inadequate to combat the draining effect of statins. In these cases I would recommend would be to supplementing 50 – 100 mg of CoQ10 each day.
