I respond very badly to algae products and even kelp. I am not certain why, whether it's contamination, or whether I cannot digest them properly. But I steer clear of them. They tend to linger in the gut area or something and I start feeling drugged, crampy and heavy and unable to think.

So no, it's definitely not for everybody. I used to take spirulina and kelp once and did very well with both, but following the virus and other possible infections, I have not been able to handle the same things as I did once. That goes for supplementary garlic too. I have to stay away from it.

I would be careful of any oceanic product personally. I use stuff I know and am comfortable with if I can. It avoids the unknowns.
