Should you swap fish oil with krill oil? Experts weigh in on the popular alternative
Krill oil, which comes from tiny, shrimp-like crustaceans abundant in the Antarctic Ocean, boasts omega-3 fatty acids that may help improve heart health, fight inflammation and support brain and nervous system health, according to medical experts.
The global krill market is expected to grow substantially over the next 10 years as an alternative to fish oil, according to data from Allied Market Research, as people seek the benefits that are abundant in fish like salmon, sardines, mackerel and anchovies.
"Whole food comes first, but krill oil makes a powerful second line of defense," Joseph Mercola, a board-certified family physician in Florida and author of the book, "Your Guide to Cellular Health," told Fox News Digital.
"The major benefit of krill oil over fish oil is that, in krill oil, the omega-3 fats – EPA and DHA – come bound to phospholipids, which makes them easier for your body to absorb and use," Mercola said.
DHA in fish oil struggles to reach the retina, for example, while krill-based DHA crosses into the eyes and helps preserve vision, he said.
Krill oil's ability to cross cellular barriers more effectively also allows it to better fight inflammation, improve memory and even counter age-related decline, Mercola added.
Synthetic fish oils are especially hard for the body to process and offer fewer benefits, he said.
Krill oil may also lower cholesterol and triglycerides, which can increase the risk of heart disease, according to a 2015 study published in the journal Lipids in Health and Disease.
Krill also has astaxanthin, a potent antioxidant with additional anti-inflammatory benefits, said Dr. David Rizik, an interventional cardiologist at HonorHealth in Arizona.
The small crustaceans have fewer toxins like mercury, often found in large fish, according to experts.
Krill are also a more sustainable option, Fox News Digital previously reported, because they are so plentiful in the Antarctic.
There are some downsides to consider, however.
"Krill oil tends to be lower in EPA and DHA when compared to high-quality fish oils, and is often more expensive," Rizik, also chief medical officer at High Level Science, told Fox News Digital.
"Fish oil, particularly when in superior triglyceride form and combined with clinically-backed nutrients, delivers consistent omega-3 levels at a better value," he said, adding that the key is how it's sourced and formulated.
But because krill oil is absorbed better, less of it is needed to see results.
The research is still new on krill oil, Rizik noted.

"Most of the long-term and large-scale clinical data on omega-3s, especially for heart, brain and metabolic health, is on EPA and DHA from fish oil," he added.
For most adults, about 500 to 1,000 mg of krill oil daily delivers effective amounts of EPA and DHA, Mercola said. Those with a shellfish allergy should check with a doctor before taking it, he advised.
Fish oil and krill oil are known to have blood-thinning effects, and krill oil's use among pregnant and breast-feeding women has not been heavily researched, according to the Cleveland Clinic.
The organization recommends consulting with doctors before adding any supplements to your diet.

How to Do An Arnold Press
Named after bodybuilding legend Arnold Schwarzenegger, this exercise builds on the traditional shoulder press by adding a rotational movement that increases muscle activation and range of motion. While a typical shoulder press starts with dumbbells at shoulder height and moves straight up, the Arnold press begins with your palms facing you in a supinated position and rotates them outward into a pronated position (palms facing forward) as you press the weights overhead. The Arnold press also increases time under tension and requires more control, especially through the midrange of the movement. This makes it slightly more challenging and beneficial for shoulder development. What does an Arnold press involve? To get started: Sit on a bench with back support or stand with your feet about shoulder-width apart. Hold a dumbbell in each hand at shoulder level, keeping your palms facing your chest and elbows bent in front of you. Engage your core by gently tightening your abdominal muscles to support your spine and maintain upright posture. As you initiate the movement, press the dumbbells upward while gradually rotating your wrists so your palms begin to turn forward. Continue pressing until your arms are fully extended overhead, with your palms now facing away from you at the top of the lift. Slowly reverse the movement. Lower the dumbbells back to shoulder level while rotating your wrists so that your palms return to the starting inward-facing position. Perform 8 to 12 repetitions for 2 to 4 sets, depending on your goals and experience level. Potential modifications Beginner: Start with light dumbbells and perform the exercise seated to increase stability. Focus on mastering the rotation. Intermediate: Increase the weight slightly and consider standing to activate more core muscles. Advanced: Use heavier weights or incorporate the Arnold press into supersets with lateral raises or upright rows. Ensure your shoulder mobility can support heavier loads and full rotation. What muscles does an Arnold press work? The Arnold press primarily targets the shoulder muscles, including: Anterior deltoid: Positioned at the front of the shoulder, this muscle plays a key role throughout the movement, particularly during the initial lifting phase. Lateral deltoid: Located on the side of the shoulder, this muscle becomes more involved as the arms move outward and overhead. Posterior deltoid: This muscle is found at the rear of the shoulder and is activated slightly by the exercise's rotational motion. Triceps brachii: These muscles at the back of the upper arms assist during the pressing portion of the lift. The trapezius and upper back muscles help stabilize the shoulder joint. The core engages to maintain posture and balance, especially when the movement is performed in a standing position. What are the potential benefits of an Arnold press? The Arnold press offers several distinct advantages for shoulder development and overall strength: Greater deltoid engagement: The rotational movement activates more parts of the shoulder than a standard press, contributing to fuller muscle development. Improved shoulder mobility: The exercise helps improve range of motion in the shoulder joint, especially in rotation and flexion. Increased time under tension: The slower, controlled motion places continuous stress on the muscles, which promotes hypertrophy (muscle growth). Better muscle coordination: The Arnold press trains your body to move more fluidly, enhancing control and stability in your upper body. Whether your goal is muscle building, athletic performance, or injury prevention, the Arnold press fits well into a variety of strength programs. The bottom line Incorporating the Arnold press into your routine can help you develop stronger, more balanced shoulders. Its unique combination of rotation and pressing engages the entire deltoid group, making it a superior option compared to standard shoulder presses. With proper form, appropriate progression, and attention to safety, this exercise can boost upper-body strength, enhance mobility, and improve overall performance in athletic and everyday activities.

How to Do A Kas Glute Bridge
The kas glute bridge is a modified form of the classic glute bridge exercise. While the traditional glute bridge primarily involves lying on your back and lifting your hips toward the ceiling by squeezing your glutes, the kas glute bridge incorporates an additional element of resistance and positioning designed to maximize glute activation. 'Kas' typically refers to a method or style of glute bridging popularized by trainers who emphasize targeted muscle activation and often involves adding a band or weight for resistance. What does a kas glute bridge involve? To get started: Sit on the floor in front of a flat bench or sturdy box. Lean back so that the space between your shoulder blades rests against the bench or box. Bend your knees so your feet are flat on the floor about hip-width apart. Place a resistance band just above your knees to create gentle outward tension or opt for a light weight. For example, you can place a barbell or dumbbell in your hip crease and hold it with your hands on each side. Engage your core by drawing your belly button slightly toward your spine. Press your heels into the floor and squeeze your glutes to lift your hips upward. As you lift, actively push your knees outward against the band or weight. This outward pressure helps activate the gluteus medius and minimus. Lift your hips until your body forms a straight line from your shoulders to your knees. Keep your ribs down and core engaged to avoid hyperextending your lower back. Pause at the top of the movement and hold for 2 to 3 seconds while maintaining the outward push against the band or weight. Slowly lower your hips back down to the starting position with control, maintaining tension on the band or weight throughout the descent. Perform 10 to 15 repetitions for 2 to 3 sets, depending on your fitness level. Potential modifications Beginner: Start without a band or weight if you find it challenging to maintain the outward knee pressure. Intermediate: Use a light to medium band or weight and increase the hold time at the top of the movement for greater muscle engagement. Advanced: To increase the range of motion, incorporate a heavier weight or elevate your feet. You can also add a single-leg variation by performing the bridge with one leg lifted. What muscles does a kas glute bridge work? The kas glute bridge primarily targets the gluteal muscles, including: Gluteus maximus: The largest and most powerful muscle of the glutes, responsible for hip extension and outward rotation. Gluteus medius: Located on the outer surface of the pelvis, this muscle is critical for hip abduction and pelvic stabilization during movement. Gluteus minimus: A smaller muscle beneath the gluteus medius that assists in hip abduction and internal rotation. This exercise engages the hamstrings and core muscles to a lesser extent, helping with pelvic stability and overall balance during the movement. What are the potential benefits of a kas glute bridge? Including the kas glute bridge in your workout can offer several benefits: Improved glute strength and activation: This exercise specifically targets all major glute muscles, which can enhance your ability to perform other athletic movements like running, jumping, and squatting. Enhanced hip stability: By engaging the gluteus medius and minimus, the kas glute bridge helps stabilize the pelvis, reducing the risk of injury during walking, running, and other dynamic activities. Proper posture and lower back health: Strong glutes support proper pelvic alignment, which can alleviate lower back pain caused by weak or inactive glute muscles. Injury prevention: Strengthening the glutes helps protect the knees and lower back from strain by improving movement mechanics and distributing forces more evenly during physical activity. Are there any risks to consider before trying a kas glute bridge? While the kas glute bridge is generally safe and effective, you should keep a few things in mind to avoid injury: Maintain proper form, avoiding excessive arching in the lower back. Use a band or weight that provides enough tension to activate the muscles without causing discomfort or forcing your knees into an unnatural position. If you experience any pain in your knees, hips, or lower back, stop the exercise and reassess your technique. Consult a fitness professional if you have pre-existing conditions or injuries to ensure this exercise is appropriate for you. The bottom line The kas glute bridge is a variation of the traditional glute bridge. By incorporating resistance and focusing on controlled movement, you can more effectively engage the gluteus maximus, medius, and minimus.
