Product Overview

High Strength Omega 3 + Astaxanthin containing 3g total fish oil per serving, providing 900mg EPA and 600mg DHA. With an added 3.6mg astaxanthin, 1500iu Vitamin D3 and Vitamins A, E and K.

Omega 3 fatty acids are compounds usually found in oily fish. Of these fatty acid compounds, two are of importance when supplementing fish oil into your daily diet: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Both EPA and DHA are building blocks of immune cells, act as inflammatory mediators and support cardiovascular health.

Benefits of Science in Sport High Strength Omega 3 + Astaxanthin

The Science in Sport High Strength Omega 3 + Astaxanthin delivers high levels of EPA and DHA. Astaxanthin is a carotenoid with anti-inflammatory and anti-oxidant properties. Dietary astaxanthin has shown an enhanced immune response and decreased inflammation.

Alongside the aforementioned health benefits, astaxanthin has also been investigated in relation to exercise performance. In a trained cycling group, astaxanthin supplementation resulted in a significant improvement in 20km time trial performance and power output following a 2-hour steady state ride. Reductions in muscle damage have been measured in athlete groups supplementing with astaxanthin.

High Strength Omega 3 + Astaxanthin is tested under the Informed Sport Certification program. This approach involves testing every single batch of SIS finished product, which leaves the Company’s factory, screened against the 2018 World Anti-Doping Agency (WADA) list. Banned substances including steroids are tested to the level of 10 Nanograms per gram, and stimulants to 100 Nanograms per gram. Batches (sampled at the beginning, during and end of each product batch) receive the recognised and respected Informed Sport* certificate and Science in Sport provides the documentation to athletes on request.

Suggested Use
  • Consume one Science in Sport High Strength Omega 3 + Astaxanthin softgel, three times a day. For best results we recommend taking with food.
  • Designed as a convenient and easy way to keep your Omega 3 levels topped up and support overall athlete health and exercise performance

Didn’t arrive. Ran out of stock.

Didn’t get any taste of orange. They are like cold liver oil tablets, soft casing and I just swallow whole, not sure why you’d need a flavour
