Red Marine algae have been studied over many years and have frequently been found to positively modulate the immune system, which strengthens it Share on X for those prone to always picking up the latest bug doing the rounds.

Many naturalistic practitioners use red marine algae to treat patients with chronic fatigue. It has also been shown to possess anti-inflammatory, analgesic and gastro-protective properties, as well as a few other uses that may surprise you.

What is Red Marine Algae?

Algae is categorised by its colour, or pigment. Red marine algae belong to the Rhodophyta class and are well known for their high antioxidant content, which may help boost the immune system to fight off free radical damage. Red algae contain an antiviral compound known as carrageenans that are believed to boost the immune system and offer protection against diseases such as the shingles virus, HIV and cold sores. Share on X It may even help fight strains of germs that are resistant to certain medications.

Health Benefits of Red Marine Algae

As well as boosting the immune system, red marine algae come with a host of other proven benefits.

  1. Eye and Skin Health

Red algae contain a good amount of the antioxidants zeaxanthin and lutein, which have been shown to prevent macular degeneration and support eye health. Share on X Macular degeneration is a condition in which the eye’s macula deteriorates. This is the part of the eye responsible for the ability to see fine detail. Macular degeneration is the leading cause of vision loss in people over the age of 60.

Lutein and zeaxanthin are carotenoid antioxidants that may prevent macular degeneration because they are concentrated in the macula and make up the macular pigment. They function both as an antioxidant and as blue-light filters to protect against damage.

  1. Reduce Pain and Inflammation

Many different forms of algae have been found to contain anti-inflammatory and pain relieving properties due to the high chlorophyll and omega-3 fatty acid content. A 2016 study published in Pharmaceutical Biology found that red algae is a natural source of compounds that contain potent biological and pharmacological properties, including gastro-protective, analgesic and anti-inflammatory activities. Share on X

Results of the study found that the Mediterranean red algae Laurencia obtuse contains significant pain-killing and anti-inflammatory properties. It’s also known for its gastro-protective ability in that it is able to inhibit a gastric ulcer by as much as 81.3 percent when taken in the amount of 50 milligrams per kilogram.

  1. Lower Cholesterol

Algae is a rich source of a plant sterol called fucosterol, which has been shown to naturally lower cholesterol, among many other health-related benefits. What’s more, algae are a good source of phytosterols, which have been shown to reduce “bad” or LDL cholesterol levels when taken in supplemental form by lowering intestinal cholesterol absorption.

  1. Immune Booster

Red algae are packed with antioxidants, further benefiting the immune system. A 2013 study found that ethanol extracts of the Callophyllis japonica and Gracilaria tenuistipitata species of red algae have antioxidant effects on the body, such as activating cellular antioxidant enzymes and suppressing certain mechanisms that kill off healthy cells. Red algae may also be able to help prevent DNA damage and fight chronic fatigue with its high antioxidant content. Share on X

Antioxidants play an important role in boosting immune system health by neutralising free radicals and moving toxins out of the body. They are also naturally detoxifying and may assist in heavy metal detoxification, weight loss and restoring blood pH levels to an alkaline status.

  1. Protects Against Herpes

One of red algae’s most notorious uses is for the prevention of the herpes simplex infection. Share on X According to a 2006 study published in Plant Medica, an isolated compound from the red seaweed Gigartina skottsbergii was shown to be a potent inhibitor of the Herpes simplex virus types 1 and type 2.

Supplementing With Red Marine Algae

According to a 2015 study, sulphated polysaccharides “have several important properties, such as anticoagulant and/or antithrombotic, immunomodulatory ability, antitumor and cancer preventive, antilipidemic and hypoglycaemic, antibiotics and anti-inflammatory and antioxidant, making them promising bioactive products and biomaterials with a wide range of applications.”

The study showed that red algae is beneficial in fighting against the HIV type 1 and type 2, the human papilloma virus (HPV), the encephalo-myocarditis virus, the hepatitis virus type A and type B and the dengue and yellow fever virus with its powerful antiviral,… Share on XSupplementing with Red Algae vegan capsules is a good way to boost the immune system, fight free radical damage, ward off disease and even balance pH levels, which can aid in weight loss.

Red Algae or Rhodophyta

The history and use of seaweed and specifically Rhodophyta are very old. Ancient Asian cultures have been using and realizing the benefits for thousands of years, but it’s been just since the 1970’s that Chinese and Japanese scientists have been studying red algae.
Red algae, almost exclusively found in the ocean. They commonly live below the kelp forest because they can survive with less light than brown algae.

Red Algae are consumed by humans, representing a rich source of fiber, protein, and minerals. The mineral content can be 20 times higher than plants growing in the ground. They retain both their gelatinous nature and color even when cooked.

Benefits of Red Algae or Rhodophytes

Studied Health Claims:

  • Weight Loss
  • Lowers Cholesterol
  • Lowers Inflammation
  • Cardiovascular Health
  • Studies claim that red algae are Cancer Fighting
  • UTI treatment

Another critical benefit is that rhodophytes are a potent antioxidant and help to counter the cellular damage done by free radicals. Free radicals are common by-products of normal internal reactions. Furthermore, pollution, UV radiation, and strenuous aerobic exercise have been connected to free radical formation.

They are also a good source of vitamin K, an important fat-soluble vitamin which plays vital roles in building your bones, protecting your heart, helping your blood to clot properly, and optimizing your insulin levels. Symptoms of a deficiency in vitamin K include hemorrhage, prolonged clotting time, and excessive bleeding.

Algae used in Food Products

According to the University of California at Los Angeles, a type of algae called carrageenan is commonly added to dairy products to give them a denser consistency. The most common algae containing products are sour cream, chocolate milk, and cheese.

The Hawaii Department of Education says algae is often added to liquids to make them thicker. For example, algae are put in shakes and malts to thicken them. It’s also an ingredient in mayonnaise to prevent it from becoming runny. Alginic acid contained in algae acts as a stabilizer or emulsifier.

The green paper-like substance used to wrap sushi rolls is algae. The green paper is a particular “leafy” variety of algae grown on farms in Asia and shipped throughout the world. The green algae are grown on strings then dried in the sun. This types of algae are exceptionally high in vitamins and nutrients.

Gelatin contains a type of algae called agar. It can solidify just about anything that comes in a liquid form. Agar was first used in China in the 17th century and is found in hundreds of foods sold in grocery stores, such as pie crusts, pumpkin pie filling, and flavored gelatin.

Non-Food Products with Algae

Algae is used in a lot of non-food products, most notable is toothpaste, without algae, toothpaste would be a runny liquid. Algae make toothpaste into a semi-solid that then dissolves with the brushing action of cleaning teeth.


It’s clear that algae and red algae are important in our lives, but when consuming algae or algae-based products, it’s important that the algae are from the ocean because algae coming from the ocean contains the highest level of vitamins, minerals, and other important nutrients.


The Wonderful Benefits of Calcium

Among all the health benefits of calcium, the most important ones are that it aids in maintaining bone and dental health, as well as helps in the prevention of colon cancer and the reduction of obesity. We need it from birth all the way until we reach old age. In our infant days, it is required for proper bone and tooth growth; during adolescence, as the bones develop, calcium is again essential to support the growth.

Finally, when we get older, our bones tend to get porous and weak, thereby requiring ample calcium intake. With so many fancy diets around us, we often tend to avoid calcium-rich foods like whole food groups, including dairy products. This avoidance often results in its deficiency.

Reports say that calcium deficiency conditions are continuously rising, particularly in women who are on low-calorie diets to get slim and are, therefore, confronted with the threat of osteoporosis. Thus, it is extremely important to consume enough calcium, vitamin Dmagnesium, and K2 throughout your life.

Calcium forms 2% of the total body weight in an adult. It is found in the bones and teeth in high volumes. Traces of the mineral are also present in the circulatory system, which prevent life-threatening haemorrhages.

Symptoms of Calcium Deficiency

Recognizing the deficiency of calcium in the body is quite easy. It has some very obvious symptoms, including the following:

  • Muscles ache and twitch
  •  Cramps and spasms
  • Palpitations
  • High blood pressure
  • Osteoporosis
  • Loose teeth
  • Gum diseases
  • Insomnia
  • Premenstrual cramps
  • Tetany
  • Hypertension
  • Arthritis

Often, children who haven’t been nourished with calcium since birth, suffer from rickets, in which the bones become weak and flexible, as a result, they have bowed legs, sunken chest, and beaded ribs. Thus, a regular supply of calcium is very important in growing children and teenagers as it can substantially reduce the risks of osteoporosis in old age. Osteoarthritis is a common ailment in one out of every three women and in one man in every 12, above 50 years of age.

Dietary Sources

There are many sources of calcium, these include the following:

It is a popular idea that milk is the greatest source of the mineral, but this is not so; broccoli can increase its levels in your diet the quickest. It is also worth noting that semi-skimmed and whole milk have very similar calcium contents.

Health Benefits

It is an essential mineral for healthy bones, gums, and teeth. Doctors often recommend women to take calcium supplements, particularly those who show early signs of bone problems such as osteoporosis or osteopenia. [2]

Strengthens Bones

Calcium strengthens the backbone, helps alleviate the presence of back pain, and keeps the bones in their proper shape. It also prevents arthritis and osteoporosis, which could hamper your freedom of movement and be extremely painful. [3]

Weight Loss

Calcium efficiently helps in maintaining optimal body weight in both males and females. If there is any deficiency of the mineral in your diet, the body will tend to release parathyroid hormone, which in turn stimulates the bones to release it into your bloodstream. This maintains the balance. On the other side, the parathyroid hormone also stimulates the production of fat and prevents its break down, which can subsequently make you obese. Basically, make sure that you are taking the right amount of calcium so that obesity does not creep in.

Protects Cardiac Muscles

It protects your heart muscles. [4] Sufficient amounts of this essential mineral can help cardiac muscles contract and relax properly. It also helps the nervous system maintain a proper pressure in your arteries. If there is a calcium drop, a hormone called calcitriol is released, which contracts the smooth muscles of the arteries, thereby increasing the blood pressure. Cardiac muscles need extracellular calcium ions for contraction. When the intracellular concentration of calcium increases, the ions gather together on the protein troponin. This stimulates the secretion of extracellular fluid and the intracellular stores, including that of the skeletal muscle, which is only activated by calcium stored in the sarcoplasmic reticulum.

Prevents Colon Cancer

Dr. Ulrike Peters,  Dr. Katherine McGlynn et al, published a report in The American Journal of Clinical Nutrition, that states that an adequate amount of calcium prevents the overall risk of colon cancer. [5] It suppresses the growth of polyps, which has the potential to lead to cancer. Its supplementation reduces the risk of adenomas as well as nonmalignant tumors of the colon. This is actually a precursor to colon cancer, but it’s still not known if calcium intake minimizes the cancer risk completely.

Reduces Premenstrual Depression

Adequate amounts of calcium lessen the symptoms of a premenstrual syndrome like dizziness, mood swings, hypertension, and many others. Low levels of the mineral might trigger the release of the hormones that are responsible for premenstrual mood swings including irritability and depression.

Prevents Kidney Stones

Kidney stones are actually crystallized deposits of calcium and other minerals in the human urinary tract. [6] The most common form of kidney stones is oxalate stones. Previously, it was thought that a high intake or high absorption of the minerals develop kidney stones, but the latest studies show that a high dietary calcium intake decreases the risk of kidney stones considerably. Other factors like high oxalate consumption from leafy vegetables like kale and spinach, as well as reduced fluid consumption, can also prove to be a big cause for kidney stones.

Controls Alkaline pH Level

Junk food, excess sugars, and preserved food items contribute to forming acidity in the body, which, according to a report published in BMJ Open journal, could give rise to kidney stones, hypertension and sometimes even cancer. [7] Calcium helps maintain a healthy pH level, thereby improving your vitality and overall health.

Regulates Blood Pressure

Research has stated that a vegetarian diet with high amounts of calcium, magnesium, potassium, and fiber will result in a regulated blood pressure. While other researchers concluded that increased intake results in hypertension. Later, it was seen that the reason for such assorted results was because these studies tested the effect of single nutrients rather than the food sources having that nutritional content. The National Institutes of Health conducted a research study called “Dietary Approaches to Stop Hypertension (DASH)”. [8] The “typical American” diet was compared with two altered diets that were rich in fruits and vegetables and a combo “DASH” diet stuffed with fruits, vegetables, and calcium. The results showed a decreased blood pressure.

To help test the combined effect of nutrients including calcium from food on blood pressure, a study was conducted to investigate the impact of various eating patterns on blood pressure. This study examined the effects of three different diets on high blood pressure and found that the combined effects of various foods still showed it to be beneficial in terms of blood pressure.

Dental Care

Calcium protects your teeth by keeping the jaw bone strong and sturdy throughout your life, which in turn ensures tight fitting teeth where bacteria cannot thrive. Thus, before your teeth and gums start giving you any trouble, be sure to maintain a calcium-rich diet. Its intake should be high, especially at young ages, so that children can grow up with strong teeth.

Transportation of Nutrients

It helps in the easy movement of nutrients across cell membranes.


Calcium, being the most important mineral, tends to get neglected the most. Children usually fuss about having milk and eventually stop drinking milk altogether. It should be widely known that such deficiencies can result in many diseases over the long term. If milk and dairy products are not desirable, try to combine these ingredients with other cereals and make recipes that involve milk and dairy products. However, all dietary supplement stores and pharmacists have supplements in their stores, though it’s always advisable to take a physician’s advice before starting any medicinal treatment.
