From the Guidelines
Combining 250mg shilajit (20% fulvic acid) with 150mg Tongkat ali (20:1 extract) daily may be considered safe for most healthy adults seeking improved energy and fertility, but the current evidence is of low quality and insufficient to fully support its effectiveness for male infertility 1. When considering the use of these supplements, it's essential to weigh the potential benefits against the lack of robust evidence supporting their efficacy.
- Shilajit contains fulvic acid and minerals that may support energy production and reproductive health.
- Tongkat ali has been studied for its potential to support testosterone levels and sperm quality. However, the methodological quality of most studies on antioxidants and herbal therapies, including those on shilajit and Tongkat ali, is poor, and the heterogeneity of the selected studies makes meta-analysis challenging 1. To minimize potential risks,
- start with lower doses to assess tolerance,
- take them with food to minimize digestive discomfort,
- consider cycling the supplements (4-6 weeks on, 1-2 weeks off) to prevent adaptation. People with pre-existing medical conditions, especially those affecting the liver, kidneys, hormone-sensitive conditions, or those taking medications, should consult healthcare providers before use, as these supplements may interact with blood thinners, diabetes medications, or blood pressure drugs 1. Monitor for side effects like digestive upset, sleep disturbances, or changes in mood, and discontinue use if you experience adverse reactions. Given the limited data supporting the use of herbal therapies for male infertility, a more effective approach may involve consulting a healthcare provider to discuss evidence-based treatments, such as aromatase inhibitors, human chorionic gonadotropin, or selective estrogen receptor modulators, which have shown promise in improving fertility outcomes 1.
From the Research
Health Benefits of Shilajit and Tongkat Ali
- Shilajit, standardized to 20% fulvic acid, has been shown to have various health benefits, including antioxidant, anti-inflammatory, adaptogenic, immunomodulatory, and anti-dyslipidemic properties 2.
- It has also been found to enhance spermatogenesis, physical performance, and relieve fatigue with enhanced production of ATP 2.
- A study on Shilajit supplementation found that it promoted the retention of maximal muscular strength following a fatiguing protocol and decreased baseline hydroxyproline levels 3.
- Shilajit has also been shown to increase total testosterone, free testosterone, and dehydroepiandrosterone (DHEAS) levels in healthy volunteers 4.
- Tongkat ali (Eurycoma longifolia) root extract has been traditionally used to improve energy and fertility, although there is limited research on its effects when combined with Shilajit.
Health Risks of Shilajit and Tongkat Ali
- There are no reported major health risks associated with Shilajit supplementation, and it is considered safe for consumption 5, 2.
- However, the chemical composition of Shilajit is not fully understood, and more research is needed to determine its long-term effects 6.
- Tongkat ali may interact with certain medications or have side effects in certain individuals, although there is limited research on its effects when combined with Shilajit.
- It is essential to consult with a healthcare professional before taking any supplements, especially when combining them.
Combination of Shilajit and Tongkat Ali
- There is limited research on the effects of combining Shilajit and Tongkat ali, and more studies are needed to determine their interactions and potential benefits or risks.
- However, based on the available research, Shilajit appears to be safe for consumption, and its combination with Tongkat ali may potentially enhance energy and fertility 2, 4.
- It is crucial to follow the recommended dosages and consult with a healthcare professional before taking any supplements, especially when combining them.
