Omegachoice Tg Omega-3 Essential Fatty Acids
Also known as: Omega-3, OM3-FA, fish oil fatty acids, essential fatty acids, Omegachoice Tg Omega-3, Omega-3 Fatty Acids (EPA/DHA)
Overview
Omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are long-chain polyunsaturated fatty acids (PUFAs) essential for human health. They are primarily found in fish oils (e.g., salmon, mackerel) and certain plant oils (e.g., flaxseed). Omegachoice Tg Omega-3 refers to a triglyceride-form omega-3 supplement, which is known for its superior bioavailability compared to ethyl ester forms. These supplements are widely used for managing hypertriglyceridemia, supporting cardiovascular health, and potentially enhancing neurocognitive function through their influence on lipid profiles and brain-derived neurotrophic factor (BDNF). Research on omega-3s is extensive, with high-quality evidence from numerous randomized controlled trials and meta-analyses supporting their efficacy and safety.
Benefits
Omega-3 supplementation offers several evidence-based benefits. It significantly reduces triglycerides (mean difference (MD): −39.81 mg/dL; 95% CI: −54.94 to −24.69; p < 0.001), total cholesterol (MD: −2.98 mg/dL; 95% CI: −5.72 to −0.25; p = 0.03), VLDL-C, and non-HDL-C. These lipid profile improvements are clinically meaningful, especially for patients with hypertriglyceridemia. Omega-3s also increase HDL-C (MD: 1.60 mg/dL; 95% CI: 0.06 to 3.15; p < 0.05) and, notably, can increase LDL-C (MD: 9.10 mg/dL; 95% CI: 4.27 to 13.94; p < 0.001), which requires clinical monitoring. Beyond lipid management, omega-3 supplementation is associated with increased serum brain-derived neurotrophic factor (BDNF) levels (Standard Mean Difference (SMD): 0.72 pg/mL; 95% CI: 0.28 to 1.15; p < 0.001), suggesting potential benefits for neuroplasticity and cognitive function. While beneficial for lipid profiles, evidence for omega-3s in preventing major cardiovascular events remains inconclusive. Lipid changes can be observed within weeks to months, while BDNF increases may occur within 10 weeks with high doses.
How it works
Omega-3 fatty acids exert their effects primarily by reducing hepatic triglyceride synthesis and secretion. They modulate key enzymes involved in lipid metabolism and influence various inflammatory pathways. In the cardiovascular system, they contribute to lipid lowering and exhibit anti-inflammatory properties. In the nervous system, omega-3s upregulate brain-derived neurotrophic factor (BDNF), a protein crucial for neuronal survival, growth, and plasticity. Molecularly, they interact with peroxisome proliferator-activated receptors (PPARs), nuclear receptors that regulate lipid metabolism, and modulate inflammatory signaling pathways like NF-κB. The triglyceride form of omega-3s, such as Omegachoice Tg, offers superior absorption and bioavailability compared to ethyl ester forms, enhancing their therapeutic efficacy.
Side effects
Omega-3 fatty acids are generally considered safe and well-tolerated. Common side effects, occurring in over 5% of users, are typically mild gastrointestinal symptoms, including a fishy aftertaste, burping, and nausea. Uncommon side effects (1-5%) may include rare bleeding tendencies, particularly at higher doses. Allergic reactions are rare, occurring in less than 1% of individuals, and are usually seen in those with known fish or shellfish allergies. Omega-3s can interact with other medications; they may increase the risk of bleeding when combined with anticoagulants (e.g., warfarin) or antiplatelet drugs (e.g., aspirin, clopidogrel). Contraindications include known fish or shellfish allergies and caution is advised in individuals with bleeding disorders. For special populations, omega-3 supplementation is generally considered safe during pregnancy and lactation at recommended doses, but medical consultation is always advisable.
Dosage
For significant triglyceride reduction and neurotrophic effects, the optimal dosage range for combined EPA and DHA is typically 2000–4000 mg/day. A minimum effective dose of approximately 1000 mg/day of combined EPA and DHA is often cited for triglyceride lowering. The maximum safe dose is generally considered to be up to 4000 mg/day; doses higher than this should be taken under medical supervision. To improve absorption and minimize gastrointestinal discomfort, omega-3 supplements should be taken with meals, especially those containing fat. The triglyceride form, such as Omegachoice Tg, is preferred due to its superior bioavailability compared to ethyl ester forms. No specific cofactors are required for absorption, but overall nutritional adequacy is recommended.
FAQs
Is Omegachoice Tg Omega-3 effective for heart health?
It effectively improves lipid profiles by reducing triglycerides and total cholesterol. However, evidence for preventing major cardiovascular events is currently inconclusive.
Are there risks of increased LDL cholesterol?
Yes, omega-3s can increase LDL-C. This effect should be monitored clinically, especially in individuals with existing cardiovascular risk factors.
How long before benefits appear?
Changes in lipid profiles can be observed within weeks to months. Neurotrophic effects, such as increased BDNF, may appear within 10 weeks with high-dose supplementation.
Is it safe to take with blood thinners?
Caution is advised due to a potential increased risk of bleeding. Consult your healthcare provider before combining omega-3s with anticoagulant or antiplatelet medications.
Does the triglyceride form matter?
Yes, the triglyceride form (Tg) of omega-3s, like Omegachoice Tg, has better absorption and bioavailability compared to the ethyl ester forms, potentially leading to greater efficacy.

It also noted an increase in LDL-C and HDL-C, supporting omega-3s' role in lipid profile modulation. The study highlights the robust evidence for lipid improvements but also raises concerns about the LDL-C increase.
- https://pubmed.ncbi.nlm.nih.gov/36103100/ – This systematic review and meta-analysis of 15 RCTs concluded that there is insufficient evidence to confirm that omega-3 supplementation significantly reduces major cardiovascular events. While the safety profile was deemed acceptable, the study emphasizes the uncertainty regarding omega-3s' direct impact on preventing cardiovascular disease, despite their lipid-lowering effects.
- https://pubmed.ncbi.nlm.nih.gov/37589276/ – This meta-analysis of 12 RCTs involving 587 subjects demonstrated that omega-3 supplementation significantly increased serum brain-derived neurotrophic factor (BDNF) levels. This finding suggests a potential neuroprotective role for omega-3s, supporting neuronal survival and plasticity. The study noted high heterogeneity among trials, suggesting caution in interpretation despite the positive findings.
