It didn't work ... my family ate it for a while, nothing changed, and even vomited ... Finally, I changed to feed the yolk with boiled eggs ... This effect is even better, as if it turned white and my hair became thinner ... My family is Bixiong. . Before and after, I didn't take it. No one will think of what they are used for ... these are health products ... it is good to say that they can't kill people, and some people think it is psychological. As for the effect, different people have different opinions ... melatonin ... my grandfather ate cod liver oil, as before ... whether he should be sick or not ... if he doesn't need it, he doesn't need it. If the dog is good, you don't need it. I only give him egg yolk, vitamins and trace elements to supplement the trace elements that the body lacks. Afraid that dog food is not nutritious enough. Other foods are snacks when you are greedy. Just eating is fun ~ ~
