• Combining omega-3 supplements with weightlifting may enhance strength and health outcomes.

  • A recent study highlights the potential benefits of adding omega-3 fatty acids to a strength training routine, noting improvements in cardiovascular and cognitive health, as well as physical fitness.

  • The research’s narrow focus raises questions about its applicability to a wider audience.

Omega-3 fatty acids are crucial for various bodily functions, particularly in supporting brain and eye health. They are also associated with better cardiovascular health and mental well-being when taken in sufficient quantities.

Recent findings indicate that when omega-3 supplements are paired with regular weight training, they could significantly boost health.

As published in the journal Nutrients, a study showed that athletes who consumed omega-3 fatty acids while engaging in a strength-training program saw improvements in their cholesterol levels, indicators of brain health, and strength levels compared to those who did not supplement their diet.

“This dual approach of omega-3 supplementation and resistance training led to notable enhancements in both biochemical markers and critical aspects of physical performance such as muscle strength, agility, reaction times, and explosive power,” according to the authors of the study.

However, the study’s scope was quite limited as it only included healthy men with previous strength training experience, casting doubt on whether the results can be generalized to the broader population, especially those with pre-existing chronic conditions.

“This leaves out a significant portion of the public, making it uncertain if the benefits observed would apply to all,” explained Alyssa Kwan, MS, RD, a clinical dietitian in cardiology at Stanford Medicine who was not involved in the research.

Nevertheless, the study proposes that omega-3 supplementation might be an affordable, easy method to enhance exercise performance.

Enhancements in Cholesterol, Brain Function, and Physical Fitness from Omega-3s

A team of researchers in Turkey conducted a controlled trial to examine the impact of omega-3 fatty acid supplementation in conjunction with weight training. Two groups of men underwent the same weightlifting protocols, but only one group was given omega-3 supplements.

The study involved thirty men aged between 18 to 30, who were selected based on specific criteria:

  • at least three years of strength training experience

  • no chronic health issues

  • non-smokers

  • abstainers from alcohol

  • the ability to train a minimum of three days each week

None of the participants were professional athletes or had used performance-enhancing supplements like creatine, omega-3s, protein powders, or branched-chain amino acids (BCAAs) within six months before starting the study.

Fifteen participants were randomly chosen to receive omega-3 supplements, with a daily dose of 3,150 mg, based on previous research that showed performance enhancement at similar dosages.

The training schedule included three sessions per week, focusing on upper body, lower body, and full body workouts. The research controlled for environmental factors in the gym such as lighting, temperature, and equipment to reduce variability in performance.

Additionally, both groups adhered to a strictly controlled diet overseen by a professional dietitian.

At the trial’s conclusion, those who received supplements displayed significant health and performance enhancements compared to the control group. Health improvements included:

  • better lipid profiles, with reductions in LDL cholesterol and triglycerides

  • lower levels of inflammatory markers

  • increased antioxidant levels, indicated by higher glutathione

  • boosted neurochemical markers, including elevated levels of dopamine, serotonin, and brain-derived neurotropic factor (BDNF)

Performance improvements featured:

  • a 13.6% increase in bench press one-rep max

  • a 9.7% increase in squat one-rep max

  • enhanced power, speed, agility, and reaction time

“The observation of such enhancements even in healthy, active individuals suggests that omega-3 can be an effective performance-enhancing supplement for athletes and physically active people,” the researchers noted.

Further research is necessary to understand how these supplements might affect a diverse range of individuals.

Do Omega-3 Supplements Enhance General Health?

The broader applicability of combining omega-3 supplementation with weight training for health and performance benefits remains uncertain.

However, the observed health benefits could be significant, even apart from their impact on exercise performance.

“These advantages could greatly influence longevity. Exercise is a proven method to reduce the risk of cardiometabolic diseases, and omega-3s also show similar beneficial effects. Enhancements in lipid profiles could decrease risks associated with heart disease and cognitive decline,” stated Kristin Kirkpatrick, MS, RD, a nutritionist at the Cleveland Clinic and co-author of “Regenerative Health,” who did not participate in the study.

Kwan further noted, “Omega-3s are known for their anti-inflammatory properties and are vital for immune resilience and overall health.”

Since the human body cannot produce omega-3s naturally, they must be sourced from foods rich in these fats like fatty fish, walnuts, or chia seeds. Omega-3 supplements, available as pills or oils, can help bridge the nutritional gap for those who do not consume these foods regularly.

However, experts recommend obtaining omega-3s from dietary sources over supplements whenever possible.

“The health benefits can be achieved through a healthy diet alone, such as by eating fish, which supports an overall nutritious diet,” added Kwan.

Kirkpatrick highlighted that some individuals, like those on blood thinners, should avoid omega-3 supplements.

As with any significant dietary or lifestyle change, consulting with a registered dietitian or healthcare provider before starting an omega-3 supplement is advisable.
