These served as valuable tools in evaluating the methodological rigor, validity, and reliability of each study. Out of the 18 articles selected for quality assessment, seven were randomized controlled trials (RCTs), three were systematic reviews, one was a Mendelian randomization (MR) analysis, one was a post hoc analysis, and six were cross-sectional studies. The selection of these articles was achieved through consensus between the two authors NRM and NK involved in the study. To determine the studies to be included, we established explicit inclusion and exclusion criteria, and extensive discussions were held among all authors to reach a consensus. In this study, we adhered to the rigorous and transparent guidelines set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to ensure the integrity of our review. The shared membership of VDR and testosterone in the nuclear receptor family underscores the significance of understanding their interaction. These findings suggest that vitamin D may potentially influence fertility, prompting further investigation into its wider physiological consequences.
However, other studies have not found an association between the two. Despite these studies, more research is needed to understand the possible effects of ashwagandha on low T. Ashwagandha is commonly used in traditional Indian medicine to help treat a wide range of ailments, including sexual dysfunction and infertility. Many companies market supplements as "cures" for low T, but very limited research supports these purported benefits. Keep reading to learn more about the herbs and supplements that may have some benefits and when to connect with a doctor about discussing management plans for low T.
Levels of DHEA peak in early adulthood and gradually decline with age—often correlating with lower testosterone in older men. While human trials are limited, animal studies have shown promising results. Calcium isn’t just for bone health—it plays a key role in muscle contraction and hormonal regulation. It acts as a co-factor for enzymes critical in testosterone metabolism.
Contrary to our expectations, we found no association between fatty fish intake and serum testosterone levels. In humans, n-3 PUFAs-enriched fish oil supplementation resulted in elevated total testosterone levels in males , and another study also found a similar, albeit not statistically significant, increase in total testosterone levels . This study aimed to examine the association between fish intake and serum testosterone levels among older males in Japan, one of the highest fish-consuming countries in the world and where a variety of fish is consumed 22,23. In humans, clinical trials have demonstrated that supplementation of fish oil rich in n-3 PUFAs 13,14 or vitamin D 15,16 increased serum testosterone levels in males. As part of a balanced diet and healthy lifestyle, sea moss can contribute to nutritional intake, which may indirectly support hormonal health, including testosterone levels. If you have low testosterone levels, incorporating more micronutrient-rich foods vitamins, and supplementation will help produce more free level testosterone and increase production. Optimizing your micronutrient intake by eating more fruits and vegetables and supplementation can help you boost natural testosterone production and correct vitamin and mineral deficiencies.
Anyone experiencing symptoms of low testosterone should speak to a doctor. Testosterone naturally reduces with age, but levels may also be low because of medical conditions or medications. Around 10% contained ingredients that may negatively affect testosterone. A varied, nutritious diet should provide a good range of vitamins. However, long-term lifestyle changes are the best means of increasing levels.
We compared the characteristics of study participants across the quartiles of energy-adjusted intake of total, fatty, and lean fish. This could be because the majority of studies were performed on animals, not humans, or because some studies suggest they’re effective while others show no improvement in testosterone levels, prompting experts to call for more research. According to Dr. Kaminetsky, fenugreek contains plant-based compounds called saponins that may cause an increase in testosterone production, though you would likely have to take between 500 and 600 milligrams per day. The herb fenugreek is often promoted as a non-medicinal way to help lactating mothers produce more breastmilk, but it may boost testosterone levels, too. For example, a recent 2020 study found that less than 25% of the 50 testosterone supplements evaluated had scientific research backing their positive effects on testosterone (even though nearly all of them—90%—purported to boost T). Sometimes, men may address the causes of low T by raising testosterone levels with medical treatments and supplementation. There are many causes of low testosterone levels, from simple aging to serious illness to chronic health conditions like obesity and diabetes.
Treatment will include a once-a-week injection into the muscle to restore natural levels of testosterone in the body. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition.

As a bonus, decreasing your dietary intake of alcohol and carbohydrates may have other benefits for your overall wellness and sex drive. Fenugreek, tongkat ali, and ashwagandha, for example, were found to have the strongest evidence out of 10 substances for raising testosterone in a 2021 review.
Similarly, the effects of vitamin D supplementation on testosterone levels remain inconclusive, with limited evidence of notable changes in TT but potential influences on SHBG and FT levels. In summary, the reviewed studies have provided valuable insights into the complex relationship between vitamin D and androgens, specifically testosterone levels, in men. However, it is important to consider that the relatively short duration of the study (12 weeks) may have limited the ability to detect significant changes in testosterone levels over a longer-term supplementation period. The influence of vitamin D on testosterone levels has been extensively investigated in various studies. Overall, the studies by Chen et al., Rafiq R et al., Sim MY et al., Chin et al., and LM Wentz et al. provide valuable and insightful information regarding the connection between vitamin D and testosterone levels. In particular, the findings support the Chin et al. study, which suggests that BMI may modify the relationship between vitamin D and testosterone levels. Although the smaller sample size of this study may limit its statistical power and generalizability, its findings provide additional insights into the specific influence of vitamin D on testosterone levels.
