Vistra Omega Concentrate x3 rTG — Norwegian Fish Oil, EPA 552 mg + DHA 368 mg, 30 capsules
Vistra Omega Concentrate x3 rTG is a premium highly concentrated fish oil supplement by Suntory Wellness, Thailand. Raw material is imported from Norway — a country with the world's most stringent fish oil quality standards. The key advantage is the rTG (re-esterified triglyceride) form: clinical evidence shows it is absorbed up to 70% more efficiently than the standard ethyl ester (EE) form, and most closely mirrors the natural structure of omega-3 fatty acids as they occur in fish.
Each capsule delivers 1150 mg of fish oil with EPA 552 mg and DHA 368 mg — triple the concentration of standard omega-3 supplements (a typical 1000 mg capsule contains only ~300 mg EPA+DHA). Mercury tested. No added preservatives. 30 capsules — a 30-day course.

Why rTG Form Matters
rTG vs standard ethyl ester (EE)
Most budget omega-3 supplements use the ethyl ester (EE) form — an artificial form produced during molecular distillation. The rTG (re-esterified triglyceride) form most closely resembles the natural structure of omega-3 fatty acids found in fish. Clinical studies show rTG bioavailability is 70% higher than EE and 50% higher than natural triglyceride (TG) form.
Triple concentration (x3)
A standard 1000 mg fish oil capsule contains only ~300 mg EPA+DHA (30% concentration). Vistra Omega x3 rTG provides 920 mg EPA+DHA per capsule (80% concentration) — three times more active omega-3 per capsule with fewer capsules needed per day.
Who Benefits and When
For heart and cardiovascular health
EPA and DHA help maintain normal blood triglyceride levels, improve vascular wall elasticity, reduce the risk of cardiovascular events and support normal blood pressure.
For brain health and cognitive function
DHA is the primary structural component of neuronal cell membranes. Regular omega-3 supplementation supports concentration, memory and cognitive processing speed.
For eye health
DHA concentrates in the retina and is an essential component for normal vision. DHA deficiency is associated with reduced visual acuity.
For anti-inflammatory support
EPA has potent anti-inflammatory properties — it regulates prostaglandin production and reduces systemic inflammation associated with chronic conditions.
How to Use
Usage Instructions
Take 1 capsule per day with a meal. Omega-3 is fat-soluble — taking with a meal containing dietary fat significantly improves absorption.

Frequently Asked Questions
How does rTG form differ from regular fish oil?
rTG (re-esterified triglyceride) form is 70% more bioavailable than the standard ethyl ester form. The body will absorb significantly more EPA and DHA from the same dose compared to regular omega-3 supplements.
Why is raw material sourced from Norway?
Norway is the global leader in fish oil quality standards. Clean, cold waters with minimal heavy metal contamination, and the strictest molecular distillation and purity testing protocols in the world.
What does triple concentration x3 mean?
A standard 1000 mg fish oil capsule contains only ~300 mg EPA+DHA. Vistra Omega x3 contains 920 mg EPA+DHA per capsule — three times more active omega-3 in the same size capsule.
Should the capsule be taken with food?
Yes. Omega-3 fatty acids are fat-soluble — taking the capsule with a meal containing dietary fat significantly improves absorption.
How many capsules come in the bottle?
30 capsules — a full 30-day course at 1 capsule per day.
