Several population-based studies found an inverse correlation between endogenous testosterone levels and cardiovascular mortality, especially in older men . Research supports this connection—studies show men experiencing depressive symptoms often have lower plasma testosterone levels . These hormone-supporting nutrients might be the missing link for men experiencing the frustrating effects of declining testosterone. However, excessive caffeine intake or poor timing close to bedtime can disrupt sleep quality, which negatively impacts testosterone production. Brazil nuts deserve special mention due to their exceptional selenium content, which supports antioxidant function and thyroid health—both important for optimal testosterone production. Men should monitor energy levels, libido, mood stability, recovery from exercise, and body composition changes in addition to testosterone levels. Clomiphene Citrate, while commonly used to stimulate testosterone production, can inadvertently increase oxidative stress, upregulate liver detox pathways, and alter hormone metabolism. Magnesium, Zinc, Vitamin D and Omega-3 fatty acids are the common supplements that help to boost testosterone levels. Omega-3 fatty acids contain anti-inflammatory properties and, thus, may assist in eliminating those inflammatory processes that have a detrimental impact on testosterone levels. Studies indicate that consumption of vitamin K2 has an impact of boosting testosterone levels. Micronutrients, especially, are critical to enabling the respective testosterone levels to be sustained at the necessary measure. Regular resistance training, getting adequate sleep, managing stress effectively, and maintaining a healthy weight can all contribute to optimal testosterone production. Four trials assessed the effects of carotenoids on relevant outcomes, but none assessed the effects on androgens (androstenediol, androstenedione, dihydrotestosterone or testosterone), oestrogens (E2, estradiol, estriol, or estrone), DHEAS or SHBG. Forest plot assessing the effects of multi-nutrient interventions on sex hormones and IGF-1 (nmol/L). Those studies that also included vitamin D within the multi-nutrient interventions are also covered in Section 3.2. They’re the unsung heroes of men’s health, particularly when it comes to hormones like testosterone. Micronutrients are the vitamins and minerals your body needs in small amounts, but don’t let their size fool you. Studies show that men with vitamin D levels above 50 ng/mL have significantly higher testosterone than men below 20 ng/mL. The low-fat paradigm that dominated nutrition advice for decades directly undermined male hormonal health. So do a little bit of personal research, add the foods mentioned to your diet, and if you’re still not getting optimal amounts of the micronutrients, supplementation can help. D3 is actually not a vitamin but a steroid hormone mistakenly named. Zinc does more than just help testosterone, it's an important mineral for immune health as well. Zinc is one of 24 essential minerals for human survival, but adequate zinc consumption also helps you thrive hormonally. Free testosterone is believed to be the form of testosterone that actually works, flowing through your body doing testosterone things. Observational research suggests that micronutrients may be protective for sarcopenia, a key health issue during ageing, potentially via effects on hormone synthesis and metabolism. Getting your micronutrient intake sorted isn’t just about boosting your testosterone levels—it’s about taking control of your health and well-being as you age. Resistance training boosts testosterone but also depletes key micronutrients like zinc and magnesium. Take vitamin D with a meal containing healthy fats, magnesium in the evening for better absorption and sleep support, and zinc with food to avoid stomach upset. A blood test can confirm your levels of vital nutrients like vitamin D, zinc, and magnesium. Which micronutrients are the most important for testosterone production? Before considering lifelong medications, work with a knowledgeable provider, like us at Purser Wellness, to test your cellular nutrient status and build a supplementation plan to fill the gaps — just like our patient success story shows. See your micronutrient levels with a CMA blood test! Low testosterone is one of the most common concerns among men today. Magnesium supports muscle and nerve function, blood glucose control, and protein synthesis. The lack of effect of increasing vitamin D on IGF-1 was confirmed in the set of trials which supplemented with vitamin D and other compounds (two or more micronutrients) (Figure 3). Only one trial was at low risk of attrition bias, and no studies used ‘mass spectrometry’ to measure sex hormone concentrations, so all were at high risk of outcome assessment bias. Many studies (58%, or 15/26) minimised performance bias by blinding participants and study personnel, and a smaller proportion (42%, or 11/26) successfully reported blinding of outcomes. Some studies reported data as ‘median’ values so could not be included in a meta-analysis, but have been included in some forest plots to help illustrate overall effects. Where RCTs examined micronutrients in conjunction with another intervention, e.g., exercise, the study was included only if the comparator group received the same non-dietary intervention.
