Can A Pre-teen Young Man With G6PD Safely Take Fish Oil Supplements, And If So, Which Ones Would You Recommend?

Hello, I have a teenage son (13yrs), and I ve been wanting to get him fish oil supplements to give him the extra nutrients he might need to develop, but I m not sure if it might be an allergen to him, because he has G6PD, can he take them? And if so, what supplements would you recommend he take(optional)?Thanks a lot!
