Hello Nandalot, welcome to GN
This is from the Boots' website:
"The following groups of people should not take XLS-Medical Fat Binder.
Those who:
Are pregnant or likely to become pregnant
Are breastfeeding
Have a BMI of less than 18.5
Eat liver or liver products once a week, with other products containing retinol (as XLS-Medical also contains vitamin A as retinol)
Are at risk of osteoporosis (post-menopausal women and older people) "
It also says:
"XLS-Medical is a proven weight loss aid. If you consume 500 calories a day fewer than the recommended intake, exercise and take XLS-Medical according to the instructions, you should find that, after 12 weeks, you will have lost significantly more weight than you would have done through dropping calories and increasing exercise alone."
However, if you reduce your calorie intake by 500 a day and exercise, you will lose weight anyway.
It sounds a bit risky to me if you are post-menopausal.
