Do not exceed the labeled serving is the one general safety instruction on the page, and it carries more weight than it seems.
Honeyfil combines eight ingredients, and only tribulus has a stated specification. If you take extra, you increase every ingredient at once without knowing the amounts. Some have recognized upper limits: the NIH lists 40 mg a day for adult zinc and 4,000 IU for adult vitamin D from all sources.
Those limits apply to your total intake, including multivitamins and fortified foods.
Take only the servings on the label, and do not double up after a missed day. If you use other supplements, add up zinc and vitamin D across them. When results seem slow, the answer is time and a fair trial, not a larger dose.
