No pregnancy or nursing statement, no age limit, no allergen list. The page names none of these.
The product is described as being for adult men, which makes pregnancy rarely relevant to the buyer but not to a household or a gift. There is no minimum age, no allergen statement and no mention of ingredients that commonly cause reactions, such as fenugreek, a legume.
The absence of warnings is not evidence of safety.
Read the bottle label, which may carry warnings the website does not. Keep the product away from children and anyone it is not meant for. If you have allergies, check each ingredient. Ask the seller in writing for a complete list of warnings and allergens if the label is thin.
