What’s better for your bod: fish oil or krill oil supplements?
Krill oil and fish oil are two of the most popular omega-3 supplements. Here, a dietitian compares and contrasts the two, and gives tips on how to buy them.
Take omega-3s, for example. I thought fish oil was the end-all, be-all, but now it seems so many people (particularly people on the Bulletproof train) are touting the benefits of krill oil. But what the heck is the difference?
To find out, I checked in with dietitian Whitney Crouch, RDN, CLT. While both krill oil and fish oil contain the omega-3 fatty acids EPA and DHA—the ones credited with improving cardiovascular and cognitive health—she says there are a few key points of difference between the two.
Supplement showdown: Krill oil vs fish oil
First up: Both fish oil and krill oil are animal sources of omega-3s with slightly different origins. “Krill oil is derived from krill, which are small crustaceans,” Crouch explains. “Fish oil is derived from fatty fish, often sardines, anchovies, mackerel, and salmon.”
One key difference between the two, she says, is that the EPA and DHA fats in each one take slightly different forms. “The fatty acids found in krill are delivered to the body in phospholipids (PL), while the EPA and DHA found in fish oil is delivered in a different formulation called a triacylglyceride (TAG).” She notes that although krill oil was once thought to be more bioavailable than fish oil—in other words, more easily utilized by the body—a more recent (albeit small) study found that they’re equally bioavailable when EPA and DHA doses are matched. So basically while they deliver omega-3s to your bod in different ways, they’re probably equally effective at getting the job done.
The other difference, says Crouch, is that krill oil contains a few nutrients that aren’t found in fish oil. “Krill oil has a naturally occurring antioxidant called astaxanthin and vitamins A and E, which may play a role in further reducing oxidative stress and inflammation,” she says. “It also contains choline, a compound similar to a B vitamin, which reduces homocysteine [an amino acid linked with heart disease], transports different lipids, and is involved in the synthesis of neurotransmitters.”
Is there anyone who shouldn’t take krill oil or fish oil?
While the buzz around krill and fish oil might lead you to believe they’re the holy grail of supplements, they’re actually not for everyone. “Anyone with a known shellfish allergy should use krill and fish oil with caution, if at all,” says Crouch. Even if you’re not specifically allergic to krill or fish but have some kind of seafood allergy, Crouch says you should still be careful because cross-contamination is possible. Check with your doctor to consider whether vegan-friendly, algae-based omega-3 supplements could be a better option.

Crouch adds that there are a few other medical concerns that could preclude you from using high-dose krill or fish oil supplements—namely, if you’re taking prescription blood thinners, have a blood clotting disorder, have low blood pressure, or are on blood-pressure lowering medication (because excessive amounts of fish oil could increase your risk of bleeding). Again, talk to your doc about alternate omega-3 options if this applies to you. (And if course, in case it’s not already clear: krill oil or fish oil supplements are not vegan-friendly!)
What to look for when you’re buying krill oil or fish oil supplements
Your first step when considering fish oil vs krill oil supplements should be talking to your doctor to see whether you need them at all, especially give the above-mentioned medical concerns. But if they’re on-board, you should look for a bottle that has a dosage of 1000mg of DHA and EPA combined. And stick to the recommended dosage, since too much fish oil can cause some super-fun side effects like bad breath, indigestion, and nausea.
Crouch says it’s also important to ensure there isn’t any, um, fishy stuff in your pills. “Look for brands that are free of impurities and contaminants like heavy metals and environmental pollutants,” she says. An easy way to do so is to see if a brand has an NSF or USP seal, which means that ingredients have been independently tested for quality (not efficacy).
The bottom line: Both fish oil and krill oil supplements are good options to add if you’re not getting enough omega-3s in your diet, provided your doctor is cool with it. They’re equally effective, although you get more antioxidants with a krill oil supplement.

Constipation is more than just "trouble going"—it's a common digestive issue where bowel movements feel infrequent, difficult to pass, or incomplete. Because a variety of symptoms can result from constipation, it stands to reason that not all constipation is the same. In fact, there are several unique types of constipation—all with different causes and treatments.
If one of your goals this year is to prioritize your gut health, figuring out the type of constipation that you are dealing with is a great way to start. To help unpack the different types and what might be causing them, we spoke with a gut health dietitian and gastroenterologist. Read on to hear their advice—especially on how to get your gut moving again.
6 types of constipation and how to treat them
Before this article, you might not have even known that different types of constipation exist—but they do! In medicine, the subtypes are broken down by a checklist called theROME IV criteria, which healthcare providers use to determine whether people have a disorder relating to the gut-brain connection, such as irritable bowel syndrome (IBS). Conditions like IBS are tricky to diagnose because scans and tests (such as endoscopies or colonoscopies) don't show that anything is wrong with the gastrointestinal tract. This is where criteria like the ROME IV checklist help; it goes over the very real symptoms that people with these gut disorders experience.
According to the ROME IV criteria, there are four main types of constipation, which include:
Functional constipation: What we typically think of when we talk about constipation (infrequent, hard stools).
Irritable bowel syndrome—constipation subtype (IBS-C): Where constipation is present with pain as a predominant feature.
Medication-induced constipation: Constipation induced by medications such as opioids (a class of drugs that slow the bowels down).
Constipation caused by defecation disorders1: Constipation caused by the dyscoordination of muscles needed to have a proper bowel movement.
Slow transit constipation2: Constipation caused by slow movement of food and stool through the intestines.
Constipation caused by inadequate energy intake: Constipation caused by not eating enough food, which yes, can 100 percent happen.
Curious to know which type you have? We've broken down the most common symptoms of each to help you figure it out.
1. Functional Constipation
"Functional constipation is constipation to which we don't actually have an explanation," says Hardy. She notes that while a low-fiber diet and lifestyle factors (like not getting daily exercise) can cause it, some people's bowels are inherently slower, which leads to constipation symptoms like straining, hard and lumpy stools, a feeling of incomplete evacuation, or blockage of the bowels.
How to treat it
"With all types of constipation, but especially functional constipation, I like to start with eating more fiber, incorporating a "constipation superfood" (more on that later), and adding a fiber supplement," says Hardy. She adds that while these strategies give you the most bang for your buck, some people need to layer on other strategies.
If this does not work, Dr. Robbins notes that providers may prescribe other types of medication like linaclotide (a medication for IBS-C that draws fluid to the bowels) or prucalopride (a chronic constipation medication that stimulates the muscles in your gut to get poop moving more efficiently) may be necessary.
2. IBS-C
Irritable bowel syndrome—constipation subtype, also known as IBS-C, is when constipation and pain are the predominant symptoms of your IBS, says Hardy. "IBS is considered a diagnosis of gut-brain interaction," she explains. Our gut and brain are highly connected through our nervous system. "In IBS, how we regulate and sense digestion via our nervous system is not working as it should," she notes.
Hardy notes that there are many reasons for this, but the dysregulation can lead to the perception of pain—especially if your gut is full of stool, which is essentially what happens when your intestines are backed up since stool hasn't moved as it normally should.
How to treat it
Hardy says IBS-C is treated similarly to functional constipation, but another avenue to consider is trying the low-FODMAP diet. This specialized diet, which involves reducing the amount of gas-producing foods you consume (think: beans and broccoli), has been proven effective for managingIBS-related pain3 in recent studies. Another option for managing IBS-C pain is to use medications that specifically work to reduce pain perception in the gut alongside resolving constipation, says Hardy.
Dr. Robbins adds that taking a daily probiotic can help some people with IBS-C, while other people might benefit from things like talk therapy, as stress4 can be a huge trigger for IBS symptoms. This is why dealing with stress—through therapy or things like meditation and exercise—may help improve your gut health.
Hardy explains that while diet and lifestyle can be helpful, most often, medications are needed to manage this type of constipation. "A type of medication called 'opioid receptor antagonists' is most often used because they block opioids from having their slowing effects on the bowels," she adds.

Dr. Robbins also says that laxatives can be used to treat this type of constipation, too, as long as it doesn't negatively interact with what you're already taking. That said, always check in with your healthcare provider before adding laxatives to your routine.
4. Constipation caused by defecation disorders
"This subtype of constipation is often caused by the discoordination of the muscles needed to have a proper bowel movement," explains Hardy. She adds that while this subtype of constipation isn't often talked about, it's actually extremely common.
To have a bowel movement, many body systems have to work together. "From generating proper pressure in the abdomen (i.e., intra-abdominal pressure5) to relaxing the pelvic floor muscles and coordinating the sphincter that helps move stool through—all of it is important for having a bowel movement," says Hardy. So if these systems are not working properly, your gut motility may take a hit.
How to treat it
Diet and lifestyle can help this type of constipation, but it's not often enough to completely solve the issue. Instead, "treatment that emphasizes pelvic floor therapy, such as biofeedback training to retrain muscle coordination, or behavioral strategies, such as using a foot stool to elevate the feet during a bowel movement, are also helpful," says Dr. Robbins.
Dr. Robbins also says that while laxatives may provide temporary relief, they're not a long-term solution for this type of constipation. Your healthcare provider can help you come up with other relief options.
5. Slow transit constipation
While not part of the ROME IV criteria for constipation, Hardy explains that constipation caused by slow movement of food and stool through the intestines is important to consider. "While this type can overlap with defecation disorders and functional constipation," she explains, "slow transit constipation can also be caused by structural abnormalities like an extra long colon6 or organ prolapses." These types of issues are most often discovered through tests like colonoscopies, endoscopies, or MRI scans.
How to treat it
Hardy explains that for most people with this type of constipation, proper nutrition (such as eating enough high-fiber foods and drinking plenty of fluids) and in some cases, medication, can be effective treatments. Treating other underlying causes, like prolapse, will also require visiting with your healthcare provider.
6. Constipation caused by inadequate food intake
"Not eating enough can exacerbate constipation and deserves its own spotlight," says Hardy, "as the management differs from other subtypes." She explains that with the rise in popularity of restrictive diets, high levels of exercise, and certain weight-loss medications, she's also seeing a lot more constipation in her clients, mainly due to this lack of nutrition.

"Our intestines move by way of muscle, and we need to ensure that muscle is getting adequate energy to function," she explains. She adds that when people are following extremely restrictive diets, they often struggle to hit their fiber targets, which can slow the bowels and worsen constipation.
How to treat it
Making sure you are properly nourishing your body is the first line of treatment for this type of constipation. If you are having trouble meeting your daily intake goals, visiting a registered dietitian, who can offer guidance and support, is helpful. They can even help you build a meal plan that focuses on fiber and other top nutrient goals. Remember: Food is fuel—not just for your digestive system, but your entire body.
When Hardy works with clients who have constipation, she uses three main strategies to help them poop more regularly: fiber supplements, "constipation superfoods," and a structured bathroom schedule.
For fiber supplements in particular, Hardy says two specific types—psyllium and partially hydrolyzed guar gum (PHGG)—are like sponges. "They hold onto water so [waste] can move through quickly and at the right consistency." But if fiber supplements end up worsening your bloating and constipation, you could be too backed up with stool, in which case she recommends talking with your healthcare provider to help resolve this.
There's also the option of incorporating more "constipation superfoods," i.e., any fiber-filled food that's going to help your bowel move more easily. Hardy says these include:
"When adding these in, don't forget to hydrate!" Hardy recommends. Staying properly hydrated can help prevent the extra fiber from causing gas or bloating.
Finally, Hardy recommends developing a bathroom routine. "About one hour before a bowel movement, your gut motility starts picking up," she explains. She notes that this typically happens in the morning after you first eat. When you first notice the sensation to "go," Hardy recommends taking a moment to do the following:

Take five deep belly breaths. This stretches your diaphragm down and relaxes your pelvic floor to prepare your body for a bowel movement. She adds that if you can do this in a sumo squat position, it can be even more effective.
Get a stool or a Squatty Potty ($25). These devices help ensure your knees are above your hips, which can help facilitate a bowel movement more easily, says Hardy.
Another strategy that is often overlooked when it comes to constipation is stress management, says Dr. Robbins. "While we don't often realize it, psychological factors, including stress and anxiety, can significantly impact our bowel habits," she explains.
"While occasional constipation can often be managed with lifestyle and dietary changes,persistent or severe constipation may indicate an underlying condition that requires professional evaluation," says Dr. Robbins. She recommends speaking with a healthcare provider if your constipation lasts longer than three weeks, or if it's accompanied by any of the following symptoms:
Severe abdominal pain, bloating, or discomfort that doesn't improve when you have a bowel movement.
Blood in the stool.
Unexplained weight loss.
Persistent nausea or vomiting.
Sudden changes in bowel habits.
Hard, painful stools that cause tears or hemorrhoids.
If you've been constipated for longer than three weeks, or if any of the above symptoms accompany your constipation, it's best to speak with a healthcare provider to rule out serious causes of your constipation, such as colorectal cancer or inflammatory bowel disease.
