Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A new technology for delivery of Omega-3 oils in foods. The amount of active ingredient (DHA/EPA fish oil) provided by the new technology (a seaweed gel encapsulant) will be 1300mg. It will be provided as a liquid oil emulsion in 300mL milk. This is a single dose delivered on one day only.

This is a crossover study with a 6-week washout period. The second treatment arm is 1300mg DHA/EPA fish oil without the
seaweed gel encapsulant. This is a single dose delivered on one day only.

The technology is planned to assist the delivery of higher concentrations of Omega-3 oils in food and beverage products, thereby facilitating the development of new functional food products.
