Marine Phytoplankton: the best supplement for psoriasis and eczema?

Chronic skin conditions like psoriasis and eczema may have a genetic element to them, but also arise in situations of depleted immunity. The latest research suggests, in fact, eczema is an symptom of an immune response in which two particular proteins interleukin-4 (IL-4) and interleukin-13 (IL-13) target the bodies own tissues (ref).

Until now, conventional treatments for eczema include topical creams, exposure to UV light, and steroids. Corticosteroid creams, in particular, come with damaging side effects that lead many sufferers to look towards more natural solutions.

In this article, we will explore the potential benefits of marine phytoplankton as a supplement for psoriasis and eczema, and review the evidence behind its effectiveness. We will also provide tips for safe and effective use, and discuss potential precautions and side effects.

A gamechanging natural supplement for dermatitis?

The exciting thing about phytoplankton is that it appears to offer something for everyone.

It wasn’t much surprise to us, therefore, when customers began feeding back to us that long term skin conditions such as dermatitis, psoriasis and eczema showed marked and, in some cases, radical improvements.

Psoriasis and eczema are both characterized by inflammation, and marine phytoplankton has been shown to have anti-inflammatory properties. In particular, marine phytoplankton contains omega-3 fatty acids and short-chain fatty acids that have been linked to reduced inflammation in the body. Additionally, marine phytoplankton is a rich source of antioxidants, which can help protect the skin from damage and inflammation.

But the efficacy appears to go beyond this. Let’s explore why that might be:

Phytoplankton is a Supremely Bioavailable Nutrient-source

One thing that marks phytoplankton out as a completely different supplement from any other, is it’s tiny cell size.

Far smaller than a red blood cell, this magical green powder can deliver its benefits, without the need to pass through the digestive tract.

Since many psoriasis and eczema suffers appear to have compromised digestive function in some way (this is why beneficial gut flora is also recommended) it is likely that conventional vitamins, minerals and supplements are poorly absorbed. Phytoplankton, however, can deliver its goodness right where its needed.

Phytoplankton Alkalizes the System

It is now conclusively proven that there is a link between psoriasis/ eczema and an acidic system. An acid system is constantly striving towards balance, organs are working harder, and because they have less available resources to deal with toxins, these are pushed through the skin. Mineral reserves of calcium, potassium and magnesium are diminished, even leached from bones, as the bottom attempts to reach optimum PH.

Since the easiest way to alkalise the system is through diet, it makes sense that adding marine phytoplankton powder (PH 8-8.5) is going to make a profound difference. Add to this the supplement’s ability to be correctly absorbed, and it’s near magic effects to find the ‘gaps’ that need to be filled in anyone’s personal makeup, and you have something which offers tremendous potential.

Phytoplankton is a Natural Source of Omega 3

Omega 3’s are a powerful anti inflammatory, and a primary means of nourishing your skin internally. Since phytoplankton is nature’s highest plant source of Omega 3, (and the only vegn source of long-chain EPA, commonly found in salmon), it’s an ideal way to restore the long term health of skin membranes. Since typical diets are deficient in the critical EPA and DHA oils, nourishing the body with a pure natural source of these can calm inflamed cell membranes. Of particular interest is  recent study which shows that Omega 3 helps leukotriene B4, an inflammatory mediator indicated in skin disorders.

Are there any Studies on Phytoplankton and Skin Conditions like Eczema and Dermatitis

Several studies have shown promising results for the use of marine phytoplankton supplements in managing psoriasis and eczema symptoms. One study found that a marine phytoplankton-based supplement improved symptoms of psoriasis, including redness, itching, and scaling. Another study found that a marine phytoplankton supplement improved skin hydration and reduced inflammation in individuals with eczema.

While more research is needed to fully understand the potential benefits of marine phytoplankton for psoriasis and eczema, these early studies suggest that marine phytoplankton may be a safe and effective supplement for managing symptoms of these conditions. If you are considering marine phytoplankton as a supplement for psoriasis or eczema, it is important to consult with a healthcare provider and follow safe and effective use guidelines.
