Foods To Avoid While Using Tongkat Ali

It's all well and good using the best natural testosterone booster on the planet, but if you're eating foods that block testosterone production, or bind to the free testosterone in your body, then you could be simply wasting your time and money. Because of this, we recommend avoiding the following foods while using any testosterone booster.

Flax Seed

Although Flaxseed is a health food, it is naturally high in Lignans, a plant compound that binds to testosterone and forces it to be excreted from your body. We recommend that you avoid all products that contain Flaxseed and Flaxseed oil while using Tongkat ali.

Polyunsaturated Fats & Trans Fats

A recent study involving sixty-nine men showed that frequently consuming polyunsaturated fats was associated with significantly lower testosterone levels [R].

Another study [R] involving twelve men looked at the effects of diet on testosterone levels after exercise and reported that polyunsaturated fat intake was linked to lower levels of testosterone.

An example of trans fats affecting testosterone can be seen in the study referenced here [R], in which 209 men showed that those who consumed the highest amounts of trans fats had 15% lower levels of testosterone than those with the lowest intake.

Soy (Tofu)

Soy is a phytoestrogen or plant-based estrogen. It contains two isoflavones, genistein, and daidzein, which act like estrogen within the body. If you are trying to increase testosterone, then it is wise not to add more estrogen to the body.


Studies show that walnuts and almonds increased levels of sex hormone binding globulin (SHBG) by 12.5% and 16%, respectively. SHBG is a type of protein that binds to testosterone, which can lead to a decrease in the levels of free testosterone in your body.


While studies have shown alcohol can reduce testosterone production in men, most of the studies that we have seen proved inclusive. We advise lowering your intake of alcohol, not only is this healthy for you, it could increase the effectiveness of the Tongkat ali you are taking.
