Is astaxanthin good for your heart?

Astaxanthin heart benefits

Did you know that your heart beats 100,000 times per day, pumping about 2,000 gallons of blood? This organ is the key part of your cardiovascular system, together with all your blood vessels that carry blood from the heart to the body and then back to the heart.

It is essential to understand how your heart works and what conditions can affect it. There are habits, foods, and supplements that can help you prevent and manage heart problems. One of the supplements associated with heart health is the pigment astaxanthin. 

How the heart works

This amazing organ pumps oxygen and nutrient-rich blood throughout your body to keep you alive. Blood goes through a system of blood vessels – elastic, muscular tubes that carry blood to every part of the body.

Blood carries fresh oxygen from the lungs and nutrients to the body’s tissues. At the same time, it takes the body’s waste products, including carbon dioxide, away from the tissues. This sustains life and promotes the health of all parts of the body.

The heart is made of muscle. It has a left side and a right side, separated by a thin muscular wall. Both sides have an upper chamber and a lower chamber. The four chambers work together, contracting and relaxing to pump blood out of the heart and through heart valves. 

How can you keep your heart healthy? 


Fruits, vegetables, whole grains, low-fat dairy, beans, skinless poultry and lean meats, and fatty fish like salmon, trout, and herring are good for your heart. On the other hand, you should avoid saturated and trans fats, salt, and added sugar. 


Aerobic exercise, such as running, cycling, swimming, or brisk walking, for 30 minutes most days of the week can help prevent or manage a heart condition. 


Stress can raise your blood pressure, so you might find ways to relieve tension. Exercising and getting enough sleep can help you unwind. Taking 15 minutes of quiet time every day might also be a good idea. Leaning on friends and family for support and doing things you enjoy can also help you cope.


Unhealthy habits, such as smoking, or drinking alcohol, also take a toll on your cardiovascular system. You should avoid even second-hand tobacco smoke because it can damage your heart. As for alcohol, one drink a day for women, or two for men should suffice if you want to keep your heart healthy. 

Astaxanthin heart benefits

A heart-healthy lifestyle can always use some extra push. The best nutrients to add to your diet are magnesium, vitamin D, omega-3 fatty acids, and coenzyme Q10. Another supplement that is showing a lot of promise is astaxanthin. 

Astaxanthin is a carotenoid pigment that acts as a powerful antioxidant and has well-known benefits for eye, skin, and brain health. Yet, studies have also revealed that it can reduce the risk of heart disease by helping with several cardiovascular conditions. 


There are two types of cholesterol: High-density lipoprotein or HDL often called good cholesterol, and low-density lipoprotein or LDL, also known as bad cholesterol.

Bad cholesterol can contribute to artery-clogging plaque. Good cholesterol, on the other hand, can help remove plaque and help protect you from getting heart disease. Having too much of the bad, or not enough of the good, can lead to heart disease.

According to a study, astaxanthin decreases the level of LDL (bad) cholesterol and increases the level of HDL (good) cholesterol. 

Blood flow 

A study on adults with metabolic syndrome showed that astaxanthin supported healthy blood flow by promoting arterial health. Another study showed that supplementing with 6mg of astaxanthin per day for only ten days showed a significant improvement in blood flow.

CRP levels 

Your body produces C-reactive protein, or CRP when there’s inflammation happening somewhere in your body. If your arteries are inflamed, you have a greater risk of heart disease, heart attack, stroke, or peripheral arterial disease. 

A study showed that subjects given astaxanthin for eight weeks experienced a 20 percent reduction in CRP levels.

Oxidative stress

Oxidative stress is a condition that occurs when there’s an imbalance in your body and free radicals exceed antioxidants. It can lead to cell and tissue breakdown and impact multiple aspects of your health. Among other things, it can cause hypertension, atherosclerosis, heart failure, and stroke.

Thanks to its antioxidant effects, astaxanthin can decrease oxidative stress on the heart and blood vessels to support cardiovascular health.

Goodwill Pharma’s Astax + 3 Direct contains astaxanthin, Vitamin C, Selenium, and Zinc, for an all-around supplement that will help with your heart and vascular health. 


Around 7.6 million people are living with a heart or circulatory disease in the UK. More than 460 of them will die today.

The heart is not just a muscle. It is the most important muscle in your body. This powerhouse, roughly the size of your fist, works ceaselessly to keep your body freshly supplied with oxygen and nutrients while clearing away harmful waste matter. 

You can help your heart work most efficiently by adopting healthy habits and giving it all the necessary nutrients through diet and the right supplements.

Low vitamin D levels and pregnancy

Proper nutrition during pregnancy is vital, but did you know that low sun exposure during the wintertime can severely affect the embryo’s development and cause a higher risk in pregnancy by triggering gestational diabetes or preeclampsia? Vitamin D is crucial for the growth of your baby’s bones and even teeth!

Still, many women lack optimal vitamin D levels while pregnant, especially in the UK, where we have less sunshine, not to mention the colder months. 

The dangers of low vitamin D levels during pregnancy

It is a fat-soluble vitamin that has a significant impact on calcium metabolism. Calcium demand increases in the third trimester of pregnancy. Because of these, vitamin D status has become an essential factor for maternal health, foetal skeletal growth, and healthy maternal outcomes. 

However, the deficiency is widespread in pregnant women and even in breastfed infants. Prenatal vitamins contain inadequate levels of this vitamin. 

Up to half of all pregnant women in the UK are affected by this deficiency, more common in the winter. Vitamin D insufficiency is shown when the blood serum level is less than 50 nm.

Research shows low vitamin D levels during pregnancy could cause adverse health outcomes such as preeclampsia, low birth weight, poor postnatal growth, bone fragility, and childhood allergy. In addition, mothers who have autoimmune diseases can link to low vitamin D levels during pregnancy. 

Factors that cause vitamin D deficiency

Scientists made a list of the most critical factors that may put a pregnant woman at risk for vitamin D deficiency. Let’s see it!

  • Obesity: body fat stores the vitamin D made in the skin, and it becomes less available to the body.
  • Darker skin contains higher level of melanin, and this reduces the production of vitamin D,
  • Medications—steroids, cholesterol-lowering drugs, diuretics,
  • Disorders – celiac disease, Crohn’s disease,
  • Limited sun exposure: during the winter season,
  • Regular use of sunscreens,
  • Living in northern latitudes

We encourage future mothers to consult their healthcare provider about their vitamin D level during pregnancy.

How much do pregnant women need?

Experts believe that the recommended amounts for pregnant women range from 600 to 2000 international units (UI) per day. However, many of them say that 600 IU isn’t enough, stating that higher amounts of 1000 to 2000 IUs daily provide optimal benefits. In addition, pregnant women require higher doses of some vitamins, including vitamin D. However, taking more than 4.000 IU of vitamin D per day may be harmful.

Most pregnancy multivitamins contain ten micrograms (400 international units), but this is not enough for women at high risk of vitamin D deficiency. Therefore, women benefit from a higher dose of vitamin D supplements. 

When to start taking during pregnancy?

Your body uses vitamin D every day, so you should get vitamin D supplementation while pregnant and breastfeeding, especially if your vitamin D level is low. If you have not taken it already, we kindly recommend you consider it. There is no evidence to show that supplementing with vitamin D will harm the baby or the mother. Nevertheless, there is plenty of evidence to show that vitamin D deficiency in babies causes severe medical conditions. 

Most healthcare providers recommend vitamin D supplementation from conception for another 3 to 6 months after your baby is born. So please do not stop taking vitamin D until you have discussed it with your doctor.

Advantages During Pregnancy

The Cochrane review update summarises the benefits of vitamin D supplementation in pregnancy. They included 30 research studies and over 3700 pregnant women.

It showed that taking vitamin D supplements during pregnancy

  • Reduce the risk of getting preeclampsia and gestational diabetes.
  • Reduces the risk of having a low-birthweight baby.
  • Reduce the risk of severe bleeding after birth.

Vitamin D supplementation may achieve all these gains. Goodwill Pharma’s Vitamin D3 tablets are formulated to provide numerous health benefits, much needed during pregnancy. 


Lots of studies show that vitamin D supplementation reduces the common risks associated with pregnancy. During the wintertime, there is less sunshine and this may cause reduced levels of vitamin D in pregnant women—the recommended dose of supplementation may be around 2000 IU. However, everybody is encouraged to consult their health care provider. Supplementation during pregnancy may start on the first day of conception and doesn’t stop even after the baby is born.Our team of writers aims to bring you the latest evidence in the field of health.

MAGNESIUM AND COVID-19: Does magnesium deficiency increase the risk of COVID-19?

Immune System

Analysing the clinical picture and pathophysiology of COVID-19, it became clear that some characteristics of the disease resemble the symptoms and signs that are a consequence of magnesium (Mg) deficiency. Therefore, many assume that Mg deficiency, which is quite common in the Western world, could certainly affect the development and course of the disease.

Since Mg is not routinely checked in clinical practice, there is not much data to clearly confirm the level of Mg in COVID. On the other hand, it should be emphasized that severe Mg deficiency with clinical symptoms is now a rarity. Instead, there is a hidden Mg deficiency that is difficult to detect by routine laboratory analysis.

Who is at increased risk for COVID-19 and where is Magnesium?

We have certainly heard many times that people with comorbidities (several diseases at the same time) have a higher risk of getting COVID and a more severe clinical picture. For example hypertension, cardiovascular disease, diabetes, and obesity. All of these diseases can cause low levels of magnesium in the blood, which some drugs can further aggravate (diuretics, proton pump inhibitors), and the addition of Mg has a positive effect.


Studies have shown that the intake of Mg in the diet significantly affects CRP Accordingly, the addition of Mg reduces the level of CRP in people with inflammation. In addition, Mg plays an important role in maintaining the function of the endothelium (the organ that coats all the blood vessels in the human body from the inside). Lack of magnesium at the endothelial level favours the processes that lead to increased thrombosis and the formation of blood clots.

Magnesium relieves inflammatory processes in the body and reduces the risk of viral infections.


Magnesium deficiency = more stress?

There is no doubt that this pandemic has created stress not only for health workers but for ordinary people due to isolation, fear, and economic uncertainty. Stress hormones lead to the displacement of Mg from cells. Which can result in increased excretion of Mg from the urine and a consequent decrease of Mg in the body. This process increases the release of stress hormones, thus creating a vicious cycle of reduced resistance to stress and further depletion of Mg.

Magnesium deficiency makes us less resistant and more sensitive to stress.

Influence of magnesium on immunity.

Mg plays an important role in shaping innate and acquired immunity. In the conditions of Mg deficiency, the production and activation of CD4 + and CD8 + T lymphocytes. (the type of lymphocytes necessary for adequate work of the acquired immunity) are greatly reduced. Damage to CD4 + and CD8 + T lymphocytes has been reported in COVID-19. Which may be partially supported by low magnesium levels. Weak immunity is a predisposition for various viral infections.
