Amino acids in nectar increase fertility

Butterflies prefer flowers with nectar containing a high concentration of amino acids. Scientists at the University of Basel have found that amino acids have a positive effect on butterfly fertility.

The researchers fed two different species of nettles to the caterpillars. The nectar of one nettle species contained far more amino acids than the other. After the butterflies had hatched, those fed with the amino acid-rich nectar laid significantly more eggs.

Dear reader,

We are often asked for amino acid product recommendations. As we generally cannot answer this in a universal way, the information collected from our German colleagues could be used as a guide to those who are looking for quality supplements: www.aminosaeuren.de. The site trialed and evaluated the products and services of the main providers in German-speaking countries. The information is currently only available in German, but you will nevertheless be able to see the names of the best manufacturers.
