FAQ
How is it possible that thanks to the daily dose I take 3,000 mg of maca, even if only 150 mg is contained?
The difference is due to the use of high quality extracts. For example, 150 mg of maca extract represents an effective dose equivalent to 3 000 mg of maca due to the extraction ratio of 20:1. The same principle applies to 300 mg of cordyceps extract (10:1), which, thanks to the concentrated extract, corresponds to an effective amount of 3,000 mg.

Does the product contain hormones?
HeldenKraft is completely hormone-free and contains only the ingredients listed. For your safety, each batch is tested for purity and the presence of harmful substances by an independent laboratory.

Is it also possible to take the capsules before bedtime?
We recommend taking maca in the first half of the day, i.e. in the morning or at midday. Maca has rather stimulating and energizing effects, so it should be avoided in the late afternoon or evening.

Is HeldenKraft suitable for women and for pregnant and breastfeeding women?
Yes, the product can also be used by women. There is no reason why this should not be the case. However, it is not suitable for pregnant and breastfeeding women. The product should not be taken during pregnancy and breastfeeding. Use is also not recommended for persons under 18 years of age.
