What are the Benefits of Marine Phytoplankton?

1. Great Source of Plant Based Energy

Marine phytoplankton is an exceptional source of energy, providing an unparalleled, powerful burst of vitality. Whether you suffer from fatigue, have trouble keeping up with the demands of a young family, or work long hours as a medical professional, a daily dose of phytoplankton can make all the difference. The nucleotides found in this superfood are the building blocks of DNA and RNA, and have been shown to boost motivation, energy expenditure, and cognitive function. Due to its tiny size, phytoplankton is absorbed directly through the mucous membranes, providing noticeable results in just 20 minutes. As noted by pioneering longevity writer David Wolfe, phytoplankton delivers ‘vital life force at the mitochondrial level of energy production.’

2. Highest Plant Source of Omega 3

Omega 3 is well-known for its ability to combat inflammation (1), which is recognized as a fundamental factor in many major diseases. Conditions such as arthritis, Crohn’s, cancer, Parkinson’s, cardiovascular disease, diabetes, and dementia are all linked to inflammation.

But how does phytoplankton help reduce inflammation? One way is through its high natural content of Omega 3 fatty acids, making it the richest vegetarian source of the long chain form.

Additionally, it contains anti-inflammatory chlorophyll, which adds to its effectiveness in alleviating conditions such as fibromyalgia and arthritis. Incorporating phytoplankton into your daily diet may help decrease inflammation and reduce your risk of developing these debilitating diseases. (2).

3. May Benefit Mood

Containing a wealth of powerful antioxidants, as well as carotenoids, amino acids, vitamins and bioflavonoids, some strains of phytoplankton also contain SOD. Superoxide dismutase helps the body scavenge harmful oxygen molecules as well as playing a critical role in immune system regulation (3).

Marine Phytoplankton offers tremendous benefits to the skin due to its anti-inflammatory, alkalising properties and high EFA content. The bioflavonoids purify the skin while protecting it from the detrimental effects of stress.

For many sufferers of chronic skin conditions such as psoriasis and eczema, phytoplankton supplementation is proving to be a breakthrough strategy. Phytoplankton’s anti-inflammatory and antioxidant properties make it an effective solution for a variety of skin issues, while its high EFA content provides deep nourishment and hydration.

4. Immune System Tonic

Marine Phytoplankton contains a wealth of powerful antioxidants, such as carotenoids, vitamins, and bioflavonoids, which play a critical role in neutralizing harmful free radicals and promoting healthy skin. Some strains of phytoplankton also contain SOD, or Superoxide dismutase, an enzyme that helps the body scavenge harmful oxygen molecules and play a crucial role in immune system regulation. (3)

The high content of essential fatty acids, along with its anti-inflammatory and alkalizing properties, makes Marine Phytoplankton a breakthrough strategy for many sufferers of chronic skin conditions such as psoriasis and eczema. The bioflavonoids present in phytoplankton help to purify the skin while protecting it from the detrimental effects of stress, leaving it healthy and glowing.

5. May Help Joint Health

Phytoplankton is an exceptional natural source of long-chain Omega 3 Fatty Acids, making it an excellent option for supporting joint health. Individuals with arthritis who incorporate a daily dose of a teaspoon or two of phytoplankton in their diet may experience improved muscle mobility and reduced inflammation. Moreover, phytoplankton contains Pantothenic Acid (B5), which may be helpful for both osteoarthritis and rheumatoid arthritis. The amino acid proline is also present in phytoplankton, providing essential benefits to the body’s connective tissues by promoting the formation of collagen, a protein that strengthens bones, muscles, and skin. Additionally, manganese in phytoplankton contributes to better mobility, allowing for more ease of movement.

6. Clears Up Skin

Marine Phytoplankton is a great addition to any skincare routine as it provides a wide range of benefits for the skin. Its anti-inflammatory and alkalizing properties and high EFA content make it an excellent choice for those looking to improve their skin health.

The bioflavonoids present in phytoplankton help to purify the skin and protect it from the harmful effects of stress, while the high content of essential fatty acids helps to improve skin hydration and elasticity.

Many people who suffer from chronic skin conditions such as psoriasis and eczema have found phytoplankton supplementation to be a breakthrough strategy in managing their symptoms.

7. May Benefit Cardiovascular Function

Marine Phytoplankton, with its rich concentration of Omega 3 Fatty Acids, is a fantastic way to support cardiovascular health. It contains nutrients such as niacin and gamma linolenic acid which may help lower cholesterol levels, thereby reducing the risk of heart attacks and stroke.

The Omega 3 Fatty Acids in phytoplankton may also aid in lowering triglycerides, a primary component of body fat, and promote a regular heartbeat. Additionally, they have been shown to help limit the growth of atherosclerotic plaque, and may have a moderate effect on blood pressure.

8. Destroys Foreign Invaders like Bacteria and Viruses

Marine phytoplankton is an excellent source of polysaccharides, which have been scientifically proven to have immune-boosting effects. These potent compounds can activate immune cells like macrophages and natural killer cells, which help to identify and eliminate foreign invaders like viruses and bacteria.

Additionally, polysaccharides can stimulate the production of cytokines, which regulate inflammation and coordinate the immune response. By enhancing the activity of B-cells and T-cells, which are critical components of the adaptive immune system, polysaccharides can help improve immune function and reduce the risk of infections. Incorporating marine phytoplankton into your diet is a natural and effective way to support your immune system and maintain optimal health.

9. May Help Regulate Blood Sugar

Marine phytoplankton has the potential to regulate blood sugar levels due to its high content of chromium and phenylalanine. Chromium, a trace mineral that is essential for glucose metabolism, regulates insulin, a hormone that helps transport glucose from the bloodstream to cells for energy production. Studies have demonstrated that chromium supplementation can improve insulin sensitivity and glucose control in individuals with type 2 diabetes.

Phenylalanine, an amino acid found in marine phytoplankton, plays a crucial role in the production of cholecystokinin (CCK), a hormone released in response to food consumption. CCK regulates blood sugar levels by slowing down stomach emptying and reducing glucose release from the liver. Studies indicate that phenylalanine supplementation can improve glucose tolerance and reduce insulin resistance in people with type 2 diabetes.

Marine phytoplankton is an abundant source of both chromium and phenylalanine, with up to 30 times more chromium than other food sources such as beef liver and broccoli. Therefore, incorporating marine phytoplankton in your diet could help manage blood sugar levels and improve glucose tolerance, especially for individuals with type 2 diabetes.

10. Improves Liver and Kidney Function

Marine phytoplankton offers potential benefits for liver and kidney function thanks to its high nutrient content and antioxidant properties. Antioxidants like carotenoids, chlorophyll, and phycocyanin, which are present in high levels in phytoplankton, have been shown to reduce oxidative stress and inflammation in the body, benefiting organ health.

Marine phytoplankton is also a rich source of nutrients that specifically support liver and kidney function. Magnesium, for example, is present in high levels in phytoplankton and has been shown to protect against liver damage and improve kidney function in people with chronic kidney disease.

Moreover, marine phytoplankton contains the amino acid L-arginine, among other amino acids and nutrients. Although research on L-arginine’s effects on liver health is limited, studies have suggested that it may have potential benefits for the liver, such as increasing blood flow and improving liver function in people with liver cirrhosis, a chronic condition characterized by liver scarring and dysfunction.

11. The highest Vegetarian Sources of B12, gram for gram

Marine phytoplankton, with its impressive B12 content, is a top contender for those following a vegan or vegetarian diet. It is the highest-known vegetarian and vegan source of B12, surpassing even nutritional yeast, which is often considered the leading source. While nutritional yeast contains 2.2mcg per 5-gram serving, marine phytoplankton contains 2mcg B12 in just a single gram. What’s more, unlike nutritional yeast which is fortified with B12, phytoplankton produces B12 naturally, making it the clear winner.

Incorporating a daily spoonful of phytoplankton (1g) can fulfill 83% of your B12 RDI, providing a convenient and easy way for vegans and vegetarians to obtain this essential nutrient. By taking just a teaspoon and a half, you can exceed your daily B12 requirement.

To Get the Full Benefits, Choose Your Phytoplankton from a Trusted Source

As far as we know, we’re one of the only – if not the only – dedicated phytoplankton shop on the web that a brand doesn’t own. We are independent, which means we sell the product we feel is the best, and that decision came after a tremendous amount of research into the subject. Not only did we order every available phytoplankton supplement from the UK, US and Asian markets, but we also contacted all of the producers.

And what we discovered was alarming.

Firstly, there are very few worldwide producers of food-grade phytoplankton. A good proportion of these (all of the cheaper products on the market and some, alas, of the more expensive) come from algae ponds. These are prone to contamination and do not allow the clear isolation of single strains. If you try these products, the colour is generally lighter and the taste much more acrid.

Other producers mix their product with water (why?), or dry the plant in a way which damages the integrity of the cell wall.

Choosing Phytality means choosing purity, sustainability and integrity.
