Can Jack3d Cause Vomiting?

can jack 3d cause vommitting? my husband recently started taking jack 3d and when he got up to the 3 scoop dose, he got violently ill after his workout. We thought he had the flu. Now 2 weeks later he took it again before his workout and was feeling fine, but after his workout he felt sick again. He vommitted again but doesn't feel like he has the flu.
