Shatavari Extract
Also known as: Asparagus racemosus Willd., Shatavari, Asparagus racemosus
Overview
Shatavari, scientifically known as *Asparagus racemosus*, is a plant native to India and other parts of Asia. It has a long history of use in Ayurvedic medicine, primarily for promoting women's health. This herbal supplement is rich in phytoestrogens, steroidal saponins, and other bioactive compounds, contributing to its various health benefits. Shatavari is commonly used to alleviate menopausal symptoms and address reproductive issues. Research on Shatavari is emerging, with initial studies suggesting potential benefits in muscle strength, adaptation, and recovery, particularly in older women. It is available in various forms, including capsules and powders, derived from the plant's roots. While generally considered safe, further research is needed to fully understand its efficacy and safety profile.
Benefits
Shatavari has shown potential benefits in several areas, particularly for women's health. Studies suggest that it may enhance muscle contractility and increase training load during resistance training, especially in older women. One study indicated that Shatavari supplementation increased training load in older women, though significant strength improvements were not consistently observed. Additionally, Shatavari has been found to reduce menopausal symptoms such as hot flashes, night sweats, insomnia, and anxiety, leading to an improved quality of life in menopausal women. While these findings are promising, the evidence is still considered emerging, and larger, more diverse studies are needed to confirm these benefits and determine the optimal dosage and duration of supplementation.
How it works
Shatavari's mechanism of action is primarily attributed to its phytoestrogenic effects, which mimic estrogen in the body. This interaction can influence muscle and reproductive health. Specifically, Shatavari may support muscle adaptation through integrin/MAPK signaling pathways. These pathways are involved in muscle protein synthesis and cellular growth. Additionally, the phytoestrogens in Shatavari can bind to estradiol receptors, potentially modulating hormonal balance and alleviating menopausal symptoms. While the exact absorption and bioavailability of Shatavari's active compounds are not fully understood, its interaction with the skeletal muscle, reproductive system, and potentially the nervous system contributes to its observed health benefits.
Side effects
Shatavari is generally considered safe, with clinical trials reporting no significant adverse events. However, due to limited comprehensive safety data, caution is advised. Common side effects are not well-documented, with most studies reporting none. Uncommon and rare side effects are also not well-documented. Potential drug interactions may occur with estrogen-sensitive medications, although specific interactions are not well-studied. Contraindications include pregnancy and breastfeeding due to a lack of safety data in these populations. Post-menopausal women may benefit from its phytoestrogenic effects, but consultation with a healthcare provider is recommended before use, especially for individuals with pre-existing conditions or those taking other medications.
Dosage
The minimum effective dose of Shatavari is typically around 1000 mg per day, equivalent to 26,500 mg of fresh weight. Optimal dosage ranges are not well-established, and more research is needed to determine the most effective and safe dosage. The maximum safe dose is also not well-defined, so caution is advised beyond the recommended doses. There are no specific timing recommendations for Shatavari intake; however, consistent daily intake is generally advised. Shatavari is commonly available in capsule form. Limited data exists on factors affecting its absorption, and no required cofactors have been identified. It is important to consult with a healthcare provider before starting Shatavari supplementation to determine the appropriate dosage and ensure safety.

Research Sources
- https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2024.1498674/full – This RCT with 17 young and 22 older women found that Shatavari increased training load and enhanced muscle contractility in older women over an 8-week period. However, it did not significantly improve muscle strength post-training, indicating potential benefits for muscle adaptation but limited impact on overall strength gains. The study was limited by its small sample size.
- https://pubmed.ncbi.nlm.nih.gov/38214710/ – This RCT involving post-menopausal women (N = 7 shatavari, N = 5 placebo) over 6 weeks suggests that Shatavari may support muscle adaptation through integrin/MAPK signaling pathways. The study's small sample size and lack of significant individual protein changes limit the strength of the conclusions, indicating a need for further research with larger cohorts.
