Testosterone Synthesis

Support for testosterone balance focuses on a holistic, foundation-first approach that prioritises whole-food nutrition and specific herbal remedies to stimulate the body's natural production processes. Rather than replacing testosterone with synthetic hormones, these methods target the hypothalamic-pituitary-gonadal (HPG) axis to restore hormonal balance (1).

Naturopathic practitioners focus on making sure the body has the key nutrients it needs to produce testosterone properly. For example, zinc, magnesium and vitamin D are especially important because they help the body create and regulate hormones.

Keeping stress levels in check is important, as high cortisol can lower testosterone (2). Diet choices and certain herbs are used to help the body stay calm and manage stress more effectively, as we shall cover.

A healthy liver and gut help keep hormones balanced. They play a role in processing excess oestrogen, which can influence overall testosterone levels (3).

In terms of healthy testosterone levels, there are 3 key nutrients that are worth knowing about:

Zinc supports hormone production and is linked to normal testosterone levels when sufficient (4).

Magnesium increases the availability of free testosterone by limiting its binding to Sex Hormone-Binding Globulin (SHBG) (5).

Vitamin D acts as what's known as a ‘pro hormone’ involved in steroid hormone production (6).

Ashwagandha is said to possess properties which help to lower cortisol levels and support increased luteinising hormone signalling, which encourages the body’s natural testosterone production (7).

Fenugreek supports higher levels of free testosterone by helping to block its conversion into oestrogen and Dihydrotestosterone (DHT), which is a potent metabolite and downstream byproduct of testosterone (8).

Shilajit is a natural substance found in the Himalayas that can increase total and free testosterone in middle-aged men, with one study showing a 23.5% increase over 90 days (9).

Studies indicate ginger may have testosterone boosting properties, especially in cases of infertility, by improving LH (luteinizing hormone) production (10).

Cruciferous vegetables assist the liver in metabolising excess oestrogen, helping to maintain hormonal balance in both males and females via active compounds (I3C/DIM) (11). Meanwhile, healthy fats provide cholesterol, the precursor required for testosterone synthesis (12).

Pomegranate intake may support lower cortisol levels and has been associated with increased salivary testosterone. Adaptogenic herbs such as ashwagandha help reduce cortisol while supporting strength and hormonal signalling (13).

It is thought that garlic may have a similar effect in reducing stress-related hormone suppression, which may ultimately allow for more testosterone to circulate (14).

Aromatase inhibiting foods including white button mushrooms, grape seed extract help limit the conversion of testosterone into oestrogen, supporting active hormone levels (15,16).

Zinc-rich (Oysters, pumpkin seeds, beef) these foods contain zinc and act as a direct hormone building block.

Healthy fats (Olive oil, avocado, salmon) provide cholesterol needed for hormone synthesis.

Magnesium-rich (Spinach, almonds, dark chocolate) increases free testosterone, the usable form of testosterone in the body.

Balanced nutrition provides the foundation for testosterone production, in that specific foods and herbs support hormone availability and metabolism

Additionally, stress management plays a direct role in hormonal regulation.
