6. Brazil Nuts (Selenium)
This tree nut is an excellent natural source of the mineral selenium and a great testosterone booster. According to studies, regular intake of selenium can significantly raise testosterone levels in serum. It also shows promise as a treatment for infertility.
The high selenium content is mainly responsible for Brazil nuts’ positive benefit on T levels. One 100-gram serving can provide 2739% of the recommended selenium RDA (about 1,917 micrograms of selenium).
Brazil nuts also have a good ratio of fats. A 100-gram serving contains 15 grams of SFAs (saturated fatty acids), 25 grams of MUFAs (monounsaturated fatty acids) and 19 grams of PUFAs (polyunsaturated fatty acids).
We recommend consuming 3-6 Brazil Nuts per day as a natural selenium supplement.
