Link Between Peanut Butter and Testosterone

Link Between Peanut Butter and Testosterone

Peanut butter has long been a popular snack item among children and adults. Peanut butter, known for its rich, nutty flavor and creamy texture, contains a high concentration of protein and beneficial fats. But that’s not all: this ubiquitous grocery item may help enhance testosterone levels.

Testosterone is an important hormone that impacts muscle growth, bone density, libido, energy levels, and more in both men and women. As we age, testosterone production decreases. Diet and exercise are examples of lifestyle variables that might alter testosterone levels.

Does Peanut Butter Support Testosterone?

Peanuts and peanut butter are nutritional powerhouses, including elements that may help enhance testosterone levels.

One of the most notable nutrients is their high monounsaturated fat content. Monounsaturated lipids have been proven to possibly boost testosterone levels while lowering estrogen. The beneficial fats in peanuts may assist in regulating hormone levels.

Peanuts are also a great source of L-arginine. This amino acid is a precursor of nitric oxide, which promotes blood vessel dilation and circulation. Improved circulation can boost testosterone production and levels. In one research, infertile men’s T levels increased when they ate meals rich in L-arginine.

Peanut Butter May Increase Testosterone Levels

While additional study is needed, several promising studies indicate that peanut butter may help enhance testosterone levels.

One research on rats examined the effects of administering a peanut protein extract. The researchers discovered that the peanut protein extract raised testosterone levels in rats after 30 days.

The researchers believe this effect is caused by the presence of L-arginine in peanuts. L-arginine is an amino acid that serves as a substrate for nitric oxide production. Nitric oxide can relax and expand blood arteries, resulting in improved blood flow. Better circulation may improve testosterone production.

This rat research implies that peanut butter may also raise testosterone levels in people. However, further research is needed to validate this impact and better understand the processes involved.

Recommended Peanut Butter Serving Size

Recommended Peanut Butter Serving Size

Serving size of peanut butter is around 2 tablespoons or 32 grams. Limiting intake to this amount can help avoid excessive calorie and carb consumption that could work against optimal testosterone production.

Spreading 1-2 servings of natural peanut butter on whole grain toast, apple slices, and celery sticks, or mixing it into a protein shake are easy ways to get your daily dose. Those looking to maximize testosterone should aim for organic, natural peanut butter without added sugars. 

Look for peanut butter with just peanuts and maybe a bit of salt in the ingredient list.

Moderation is key, as having too much peanut butter could lead to weight gain which lowers testosterone. Stick to 1-2 servings daily as part of a balanced, healthy diet and active lifestyle for the best chance of seeing a testosterone boost.

Combining Peanut Butter with Other T-Boosting Foods

Peanut butter can be combined with other foods that may help support healthy testosterone levels in men. Some foods to consider pairing with peanut butter include:



Eggs are rich in vitamin D and cholesterol, which are building blocks for testosterone production. Try spreading peanut butter on whole-grain toast and topping it with over-easy eggs for a protein-packed breakfast. 

The healthy fats in peanut butter can also help absorb fat-soluble vitamins like vitamin D from the eggs.


Oysters are the highest dietary source of zinc, which is essential for maintaining healthy testosterone levels. Oysters and peanut butter can be paired by spreading peanut butter on crackers and topping with freshly shucked oysters. 

The zinc and magnesium from the oysters combine nicely with the healthy fats in peanut butter.



Spinach is loaded with magnesium, which helps boost testosterone levels especially when combined with intense exercise. Make a peanut butter smoothie with spinach, milk, banana, and a scoop of peanut butter for a drinkable snack. 

The magnesium in the spinach complements the monounsaturated fats from the peanut butter.

Pairing peanut butter with eggs, oysters, and spinach can provide key nutrients that work together to optimize testosterone production. Be sure to consume peanut butter in moderation as part of a balanced diet for overall health.

Who May Benefit Most

Certain groups may see more benefits from adding peanut butter to their diet to support healthy testosterone levels.


Vegans and vegetarians frequently eschew meat, eggs, and dairy, which contain high quantities of zinc and magnesium. These minerals are necessary for testosterone synthesis. Peanut butter can help vegetarians and vegans address nutritional shortages. Just 2 tablespoons provides nearly 10% of the recommended daily intake for both zinc and magnesium.


An intense workout can reduce testosterone levels over time. Athletes must consume adequate calories, protein, fat, and micronutrients to maintain hormonal health. Peanut butter is calorie-dense, with roughly 200 calories per serving. 

It also includes plant-based protein for recuperation. Including it in smoothies, porridge, or sandwiches can help athletes satisfy their nutritional requirements.

Adult Men

After the age of 40, testosterone levels naturally fall by roughly 1% every year. Dietary practices can help older men maintain healthy testosterone levels. Peanut butter contains monounsaturated fats, minerals, and vitamin E, all of which have been associated with increased testosterone in aged men. 

Consuming it daily might assist elderly men acquire important nutrients that their systems may not absorb and use as well.


Peanut butter’s primary contribution to hormonal health is its high content of healthy fats, proteins, and micronutrients, all of which contribute to a well-rounded diet.

Adopting a balanced dietary strategy that includes modest amounts of nutrient-rich foods like peanut butter is the most practical way to promote testosterone and overall hormone health. The key, like with any dietary component, is moderation and the synergy of a well-balanced nutritional intake.
