Although these are made from natto (fermented/cultured soybeans) I am shocked that this company uses soybean oil in them. The oil is not fermented and is not healthy or digestible! I hadn't realized they did this and have been taking these every morning for exactly two weeks. From day 2, I have been getting heartburn (which I never have) starting early afternoon. By mid-afternoon, I have had stomach pain that lasts for around 5 hours. Today, having realized that this wasn't some kind of virus and I was probably reacting to these, I didn't take one with breakfast. I am feeling completely normal. No heartburn, no pain. And, yes, I did follow the directions and take them with fat. The gummies for kids do not contain soybean oil and my children and husband (who takes the gummies instead of these soft gels) are doing great with them and love them. I will try them starting tomorrow and will update, if necessary
