Best Omega-3 Supplement: iThrive Essentials Marine Omega 3 Complex

iThrive Essentials Marine Omega 3 Complex isn’t just another fish oil capsule. It is a next-generation, dual-source Marine Omega-3 softgel that combines SuperbaBoost® krill oil with triple-strength Peruvian anchovy fish oil, stabilized & protected with AstaReal® astaxanthin and natural vitamin E. This unique combination delivers highly absorbable EPA and DHA, along with antioxidant protection, to support heart, brain, joints, skin, and cellular health.

Traditional omega-3 supplements often fail to deliver the results your body truly needs. Many standard fish oils oxidize quickly, can cause fishy reflux, and provide omega-3s in a form that the body struggles to absorb. iThrive Marine Omega 3 Complex addresses these challenges by combining potent marine sources with natural antioxidants, ensuring better absorption, stability, and effectiveness at the cellular level.

This blog will provide an in-depth understanding of why omega-3 is so essential, why most people today are unknowingly deficient, and why dual-source marine omega-3 supplements like krill + fish oil are proving more effective than single-source alternatives. You’ll also learn how astaxanthin enhances omega-3 benefits, supporting everything from heart and brain function to skin and joint health.

What is Omega 3

Omega-3 fatty acids are essential fats your body cannot produce on its own, meaning they must come from diet or supplementation. The two most important types of Omega 3s are EPA (Eicosapentaenoic Acid), which helps reduce inflammation, support heart health, and improve joint comfort, and DHA (Docosahexaenoic Acid), which is crucial for brain function, eye health, mood balance, and memory.

Despite their importance, most people fail to get enough omega-3 in their daily diets. Modern eating habits, heavy in processed foods and omega-6 fats, create an imbalance that leads to chronic inflammation, low cellular function, and silent damage to heart, brain, and joints. Simply taking a generic fish oil capsule is often not enough, because many are poorly absorbed, lack antioxidants, or degrade before they can be utilized by the body.

Why Omega-3 Deficiency Is So Common and How It Impacts Everyday Health

Modern diets are low in omega-3

Most people consume excessive amounts of processed foods, refined vegetable oils, and fast food. These diets are high in omega-6 fatty acids but low in essential omega-3s like EPA and DHA. This imbalance can trigger chronic inflammation, which negatively affects the heart, brain, joints, and skin.

Regular fish may not provide enough EPA and DHA

Even those who eat fish occasionally may not get sufficient omega-3s. Many commonly consumed fish, such as farmed salmon or tilapia, have lower levels of EPA and DHA than required for optimal health. Additionally, cooking methods like frying can destroy the omega-3 content.

Low omega-3 intake affects multiple body systems

Deficiency can subtly impact everyday health over time. Common signs of deficiency include brain fog, poor memory, low energy, dry or prematurely aging skin, joint stiffness, and irregular cholesterol or triglyceride levels.

Standard fish oils often fail to deliver bioavailable omega-3s

Many fish oil supplements contain triglyceride-bound omega-3s that are not easily absorbed. They may also oxidize quickly, reducing potency before reaching the cells.

Krill Oil vs Fish Oil: Which One Is Better?

Source and composition differences

Krill oil is extracted from tiny crustaceans found in Antarctic waters, often referred to as Antarctic krill fish oil. It contains omega-3s bound to phospholipids, which are similar to the fats in our cell membranes. Fish oil , on the other hand, comes from fatty fish such as anchovies, sardines, or mackerel. Most fish oils contain omega-3s in triglyceride or ethyl ester form. The structural difference affects how well the body absorbs and utilizes the EPA and DHA.

Absorption and bioavailability

Phospholipid-bound omega-3s in krill oil are absorbed more efficiently than standard fish oil triglycerides. This means that a smaller dose of krill oil can deliver similar or even better omega-3 levels in the bloodstream compared to a larger dose of regular fish oil. That is why krill oil soft gels are preferred for people seeking fast and effective omega-3 absorption.

Antioxidant protection

Krill oil naturally contains astaxanthin, a powerful antioxidant. Astaxanthin protects the omega-3 fats from oxidation, supports cellular health, and provides additional benefits for the skin, eyes, and mitochondria. Most standard fish oils do not contain natural antioxidants and may require added vitamin E to prevent rancidity. Marine Omega-3 Astaxanthin soft gels combine both krill oil and antioxidants for superior stability.

Digestive comfort and aftertaste

Many people report that fish oil capsules cause fishy burps or reflux. Krill oil is generally better tolerated and does not produce an unpleasant aftertaste due to its phospholipid form and smaller serving size. This makes krill + fish oil supplements more convenient for regular, long-term use.

EPA and DHA content

Fish oil, especially triple-strength anchovy fish oil, typically delivers higher amounts of EPA and DHA per capsule. Krill oil has lower absolute omega-3 content but compensates with higher absorption and phospholipid benefits. Combining both sources in one supplement gives you the high potency of fish oil and the bioavailability of krill oil.

Overall benefits

• Krill oil: Superior absorption, antioxidant protection, easier on the stomach, supports heart, brain, and joint health efficiently.

• Fish oil: High potency EPA/DHA for cardiovascular, cognitive, and anti-inflammatory support.

• Dual-source formula (krill + fish oil): Offers the best of both worlds, making it one of the most effective omega-3 soft gels for overall health, including heart, brain, joints, skin, and cellular function.

All About iThrive Essentials Marine Omega 3 Complex

Ingredients and Their Benefits

SuperbaBoost® Krill Oil

SuperbaBoost® Krill Oil is sourced from small crustaceans in the Antarctic waters, often referred to as Antarctic krill fish oil. It is rich in omega-3 fatty acids, primarily EPA and DHA, bound to phospholipids, which enhances absorption compared to standard fish oils. The phospholipid-bound omega-3s integrate directly into cell membranes, supporting brain, heart, joint, and eye health. Additionally, krill oil naturally contains astaxanthin, a powerful antioxidant that protects omega-3s from oxidation, ensuring their stability and effectiveness. Regular intake of krill oil soft gels has been shown to improve cardiovascular health by maintaining optimal triglyceride and cholesterol levels.

Triple Strength Anchovy Fish Oil

The fish oil in this formula is derived from Peruvian anchovies, known for their high concentrations of EPA and DHA. The oil is concentrated to deliver a potent dose of omega-3s in their natural triglyceride form, which is highly bioavailable. Anchovy fish oil supports heart health, cognitive function, and anti-inflammatory activity. By combining this with krill oil, the dual-source formula ensures both high potency and superior absorption, making it one of the best marine omega-3 soft gels available.

Astaxanthin (AstaReal® from Haematococcus pluvialis)

Astaxanthin is a natural antioxidant derived from microalgae (Haematococcus pluvialis). It provides protection against oxidative stress, supporting skin health, eye function, and mitochondrial energy. In the Marine Omega-3 Complex, astaxanthin stabilizes the omega-3 fats, ensuring they remain effective and delivering added antioxidant benefits. This combination of krill oil astaxanthin and fish oil enhances endurance, recovery, and overall cellular health.

Vitamin E (D-Alpha Tocopherol from Mixed Tocopherols)

Vitamin E is a fat-soluble antioxidant that protects polyunsaturated fatty acids, including EPA and DHA, from oxidative damage. It also supports cardiovascular health, skin vitality, and immune function. In this formula, vitamin E complements astaxanthin to protect the integrity of omega-3s, ensuring you receive maximum benefit from each Marine Omega-3 soft gel. It also prevents lipid peroxidation inside the cells, which is crucial as omega-3s also get oxidized inside the cells. It is derived from Non-GMO Sunflower Lecithin & is added with mixed tocopherols which makes the Vitamin E complete.

Choline and Phospholipids

Krill oil provides phosphatidylcholine, an essential nutrient for brain and liver function. These components help transport fats throughout the body, support liver detoxification, and enhance cellular energy production. By including these structural lipids, iThrive Essentials Marine Omega-3 Complex ensures that the omega-3s are not only absorbed but also effectively utilized by your cells.

How iThrive Essentials Marine Omega-3 Complex Works

Give your cells the right fat (EPA & DHA)

EPA and DHA are long-chain omega-3 fatty acids that the body cannot produce in sufficient amounts. These essential fats are incorporated into cell membranes, especially in the brain, heart, eyes, and immune cells. By becoming part of the membranes, EPA and DHA help cells communicate more effectively. This affects key processes such as reducing inflammation, supporting neurotransmission, improving blood lipid management, and enhancing cellular energy. Using a krill + fish oil supplement like iThrive Essentials Marine Omega-3 Complex ensures that your cells get the essential omega-3s they need to function optimally.
