Hiomega
Also known as: Omega-3, n-3 fatty acids, fish oil, flaxseed oil, Eicosapentaenoic acid (EPA), Docosahexaenoic acid (DHA), Alpha-linolenic acid (ALA), Omega-3 Fatty Acids
Overview
Omega-3 fatty acids are essential long-chain polyunsaturated fatty acids (PUFAs) primarily comprising eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found abundantly in fish oils, and alpha-linolenic acid (ALA) found in plant sources like flaxseed. Hiomega is a branded supplement typically containing EPA and DHA. These essential fats are crucial for cell membrane structure and function, playing vital roles in cardiovascular health, cognitive function, and modulating inflammatory responses. Extensive research, including numerous randomized controlled trials and meta-analyses, supports their use, though findings on specific clinical outcomes can be mixed. They are widely recognized for their anti-inflammatory and neuroprotective properties, making them a popular nutritional supplement.
Benefits
Omega-3 supplementation offers several evidence-based benefits. For cardiovascular health, moderate evidence suggests a reduction in the risk of major cardiovascular events and myocardial infarction, though benefits for overall mortality remain unclear. For instance, a meta-analysis of 15 RCTs indicated some reduction in cardiovascular events but cautioned against broad prevention claims. In cognitive function, omega-3s show a positive effect on primary memory, with a standardized mean difference (SMD) of 0.77, indicating a moderate effect size. Furthermore, omega-3 supplementation significantly increases serum Brain-Derived Neurotrophic Factor (BDNF) levels (SMD: 0.72 pg/mL), which is linked to neuroplasticity and cognitive health. While some studies explored lean body mass preservation in cancer patients, no statistically significant overall effect was found. Cardiovascular patients and aging populations or those at risk for neurodegenerative conditions may benefit most. Cognitive and BDNF improvements can be observed within 10 weeks, while cardiovascular outcomes require longer-term supplementation.
How it works
Omega-3 fatty acids exert their effects primarily by incorporating into cell membranes, altering their fluidity and function. They modulate inflammatory pathways by serving as precursors to anti-inflammatory eicosanoids and resolvins, thereby reducing systemic inflammation. Omega-3s also influence gene expression related to lipid metabolism and neuronal function. In the cardiovascular system, they contribute to anti-inflammatory and anti-thrombotic effects. Within the nervous system, they support neuroprotection and modulate BDNF levels, which are critical for neuronal growth and survival. Molecularly, they interact with cell membrane phospholipids and nuclear receptors like PPARs. Omega-3s are absorbed in the small intestine, with bioavailability enhanced by co-ingestion with fat and varying by formulation (triglyceride forms generally have better absorption than ethyl esters).
Side effects
Omega-3 fatty acids are generally considered safe with a low incidence of adverse effects. The most common side effects, affecting more than 5% of users, are mild gastrointestinal discomforts such as a fishy aftertaste, burping, or nausea. Uncommon side effects, occurring in 1-5% of individuals, include an increased bleeding tendency, particularly at higher doses. Rare side effects, affecting less than 1% of users, may include allergic reactions. Omega-3s may interact with certain medications; specifically, they can increase the risk of bleeding when combined with anticoagulants (blood thinners) or antiplatelet drugs. Therefore, caution is advised for patients with bleeding disorders or those on anticoagulant therapy. For special populations, omega-3 supplementation is generally considered safe during pregnancy and lactation at recommended doses, but consultation with a healthcare provider is always recommended.
Dosage
The minimum effective dose for cardiovascular benefits is often studied at 1 gram or more of EPA+DHA daily. Optimal dosage ranges from 1 to 4 grams per day, depending on the specific health indication. The maximum safe dose is generally considered to be up to 3-4 grams per day; higher doses should only be taken under medical supervision. For optimal absorption, omega-3 supplements should be taken with meals that contain fat. The triglyceride form of omega-3s may offer better bioavailability compared to the ethyl ester form. Co-ingestion with dietary fat significantly enhances absorption. There are no specific cofactors required for omega-3 efficacy, but overall nutritional status can influence their benefits.
FAQs
Is omega-3 supplementation effective for heart disease prevention?
Evidence is mixed; some studies show a reduction in major cardiovascular events and myocardial infarction, but a clear benefit for overall mortality has not been consistently demonstrated.
How soon can cognitive benefits be expected?
Some studies have shown improvements in memory and increased Brain-Derived Neurotrophic Factor (BDNF) levels within as little as 10 weeks of consistent supplementation.
Are there risks of bleeding with omega-3 supplementation?
There is a slight increased risk of bleeding, particularly at high doses or when combined with anticoagulant or antiplatelet medications. Consult your doctor if on blood thinners.
Can omega-3 be taken with other medications?
Generally yes, but caution is advised when combining with blood-thinning medications due to the potential for increased bleeding risk. Always consult a healthcare professional.
Is fish oil better than plant-based omega-3?
EPA and DHA from fish oil have more direct biological effects. Plant-based ALA must be converted to EPA/DHA in the body, a process that is often inefficient.

- https://pubmed.ncbi.nlm.nih.gov/36103100/ – This systematic review and meta-analysis of 15 RCTs investigated omega-3 fatty acids for cardiovascular prevention. It found moderate evidence for reducing major cardiovascular events and myocardial infarction but insufficient evidence for mortality benefits, noting an acceptable safety profile. Limitations included heterogeneity and variable doses across studies.
- https://jamanetwork.com/journals/jama/fullarticle/1357266 – A large meta-analysis of 20 RCTs involving 68,680 patients found no statistically significant association between omega-3 supplementation and all-cause mortality, cardiac death, sudden death, myocardial infarction, or stroke. The relative risks were close to 1, suggesting minimal effect. The study's strengths include its large sample size and rigorous methodology.
- https://pubmed.ncbi.nlm.nih.gov/37589276/ – This meta-analysis of 12 RCTs (n=587) demonstrated that omega-3 supplementation significantly increased serum BDNF levels (SMD 0.72, p<0.001), indicating potential neuroprotective effects. Subgroup analyses supported these effects across different omega-3 sources and dosages, though limitations included a small sample size and high heterogeneity (I2=84%).
