Queal Intolerance

[Gferreira]

I have been taking Queal for more than three years now, and I am a pleased customer. For the first two years, I had no complaints whatsoever. However, since June/July last year, I noticed that whenever I took Queal in the morning and ate some kinds of dairy, it would give me severe diarrhoea within an hour of consumption. I removed certain products (mozzarella cheese or any dairy-based sauce) that seemed to trigger this reaction from my diet, and it helped initially.

Over time, the problem got worse again. I stopped taking Queal with milk and removed all dairy from my diet in the first part of the day. That was already a challenge since I always ate a lot of dairies and never had any issue. At some point, I had severe diarrhoea many times a day. Once, I tried taking only Queal, without milk, the whole day to test whether it could be any other influence. I did not leave the toilet. Whenever I ate dairy at any different setting without taking Queal on that day, I would have no issues.

Eventually, I removed Queal from my diet. It has been a month now that I have no problems with my bowel. However, I enjoy the time it saves, and I would love to continue taking it. Has anybody ever experience something similar? Do you know which component(s) could be causing this reaction? Is there a way to take Queal without running into these issues?

Thanks in advance!

I'm lactose intolerant, but Queal gives me no trouble, been using Queal for 5 years now, and happy with it.

Have you tried the Queal Vegan shakes? You might be sensitive to some dairy ingredients.

I had a similar problem when I started working out less due to the lock-down and noticed it was mostly after consuming the Athletic variant.
A quick google search will show that consuming excess whey protein can have digestive side effects, among which diarrhoea, so I toned it down to the standard meals to match my lifestyle and now all is fine again.

Lactose intolerance is caused by a lactase deficiency, so you will develop lactose intolerance symptoms depending on how much lactose you consume and how much lactase you produce to counterbalance it.
Lactase production varies in individuals and can decrease with age or as a result of disease or medical treatment.
So you might want to talk to your general practitioner about it, and likely need to reduce lactose intake by cutting and/or substituting.
