Gas pain

Hi Moreless,

I have a friend that is an A blood type and he has a severe sensitivity to acidic foods, such as lemons.

He started taking your drink for 3 days and using lemon and I'm not sure of the kelp type because he did bought it with some other ingredients.

On the 3rd day, he got extreme gas pain and stopped the drink. The next day, the pain went away. The day after that, he got extreme gas pain and I had him put cold on it to contract the gas.

Question: What would be a good kelp for him to take and would he better off with ACV instead of Lemon juice?

Thanks,
