A Great Product!!!
What drew me to this product in short - the Omega 3 from fish originally comes from a plant source like seaweed. Fish eat the seaweed and their bodies are saturated with Omega-3s
So, why not go directly to the source :)
The other factor is that this seafibre format has a much longer shelf life - most fish-derived oils and capsules go rancid very quickly and are often useless by the time you consume them.
Not so with this product !!!

Promotes satiety
I’ve been taking this for several weeks now and it’s impossible to track individual supplements to certain outcomes, though the research on the benefits of seaweed are clear so I’m pretty confident it’s been a health boost. What I can say is that it does have an effect of making me feel fuller, so if I take it in the late afternoon I do notice that I am fuller at dinner and eat less. Overall I have definitely lost body fat - I am sure that these supplements are part of this! Also my digestion has never been better.
