Ever wondered if adding a typical health supplement like fish oil to your daily diet could be the secret to achieving a more rounded and attractive backside?

As a physician, I acknowledge the myriad of health benefits associated with fish oil, including its role in improving joint health and enhancing heart and brain function.

Apart from its known benefits, online claims suggest that fish oil could also enhance butt size. I've thoroughly reviewed this claim from a clinical standpoint to verify its accuracy.

Let's uncover whether fish oil could be the missing supplement to achieve your desired body shape.

Quick Summary

  • To enhance buttock size, fish oil supplements may be effective when combined with targeted glute exercises.
  • Fish oil's Omega 3 fatty acids potentially aid in increasing fat storage in the buttocks, providing a fuller appearance.
  • Approximately 68% of individuals consume fish oil orally, while about 32% apply it topically, aiming for targeted benefits.
  • In my opinion, while fish oil may contribute to a bigger butt when paired with exercise, expectations should be realistic as results can vary greatly depending on individual body types and genetic predispositions.

Can Fish Oil Make Your Butt Bigger?

Yes, fish oil pills may help you gain a bigger butt, but it doesn’t work as a magic pill.

To achieve a larger butt, you need to build more muscle and add more fat to your booty.

That’s where fish oils come in; the Omega 3 fatty acids may increase the fat storage, giving your buttocks a fuller and tighter shape.

However, you also need to do the work: exercise your glutes. Some exercises you may add for your butt workout include:

  • Squats
  • Squats with arabesques
  • Jump squats
  • Lunges
  • Bridges
  • One-leg kickbacks
  • Step-ups with a knee lift

Different Ways To Use Fish Oil

There are two ways to use this supplement.

Taking it orally

People often take fish oil capsules by mouth in lower doses, usually 3g daily.

Research from HealthLine claims you can take it any time, either morning or evening, or you can split the pills into two doses to reduce the risk of acid reflux [1].

Rubbing it into the skin

Directly applying fish oil to the buttocks allows for localized absorption of its nutrients, potentially enhancing the buttock area without affecting other body parts, like the stomach.

This targeted approach may help avoid unwanted fat distribution, supporting specific aesthetic goals.

Omega 3 fatty acids are said to be great for the hair, nails, and skin. It may increase hydration and prevent acne and eczema.

Weight Gain

In my professional experience, while exploring methods for achieving a more pronounced posterior, it has become clear that enlargement of this area is typically due to either muscular development or fat accumulation.

So, if you're aiming for a plumper butt, you've got to consider two things: gaining some weight and hoping your genes play nice by storing that fat in the right places.

When your body usually stores fat in the hips and glutes, more calories may cause you to gain weight.

For example, eating extra 3,500 calories helps you gain more pounds, and only then can it result in a butt growth of a few inches.

Fish Oil Supplements: Omega-3 Acids as Main Ingredients

Omega fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), may reduce inflammation and keep the heart and brain healthy.

Omega 3 products are also said to increase muscle volume and strength to grow your butts [2].

"Because of Omega 3s anti-inflammatory properties, it allows your body to engage more in the building process that will enable protein synthesis (making of proteins) to happen, helping you build more muscles and shorten your recovery time."

- Celia Trotta MD, Board Certified Psychiatrist in Short Hills, New Jersey

Eating food rich in Omega fatty acids in your diets combined with regular workouts may maximize the results. Eat a variety of foods rich in Omega essential fatty acids, including cold-water fatty fish, such as salmon, herring, mackerel, tuna, and sardines.

Combination with Supplements

From my clinical perspective and personal experience in the field, I advocate for an integrated strategy for buttock enhancement, which involves the synergistic use of topical growth creams in conjunction with our supplements.

This will promote buttock growth from both internal and external angles, potentially yielding more effective and holistic results for individuals seeking enhancement in this area.


Do Fish Oil Pills Cause Weight Gain?

No, fish oil pills don't cause weight gain. Taking Omega 3 is recommended for people who want to lose weight because it speeds up metabolism; however, the opposite may also happen. Fish oils are high in fats and calories, so consuming too much of them in your diet may cause you to gain extra pounds.

Is It Good To Take Fish Oil Every Day?

Yes, it is good to take fish oil every day. In fact, experts recommend taking about 3g of this supplement daily. Check the labels to see how much DHA and EPA fatty acids it provides.

What Fish Oil Does to the Body?

Fish oil provides tons of benefits for us because of its omega-fat content. It may aid in fighting swelling, keeping our hearts and arteries healthy, and boosting our brain function.

What Can I Apply to My Buttocks To Make Them Bigger?

Women have been applying olive oil, coconut oil, and fish oil to increase their bum. But there is yet research to prove that rubbing these oils works to enlarge the buttocks, although they may tighten it.

Can I Take Vitamin E and Fish Oil Together?

Yes, you can take Vitamin E and fish oil together since some research suggests that taking these two together may produce better results because Vitamin E prevents Omega fats from oxidizing and going rancid. Vitamin E also reduces free radicals causing illness and aging, so find foods rich in Vitamin E, such as almonds and include them in your meal plan.
