What is ashwagandha?

Ashwagandha (botanical name: Withania somnifera) is a leafy shrub found in India, the Middle East and parts of Africa. It has long been used in traditional Indian medicine, better known as Ayurvedic medicine. Sometimes referred to as Indian ginseng, in Ayurvedic medicine, ashwagandha is regarded as a 'rasayana' capable of regenerating and invigorating the body, and even helping you live longer.

What are ashwagandha's properties?

Ashwagandha is beneficial due to its composition. It is high in withanolides. These bioactive compounds are known for their anti-inflammatory, antioxidant and adaptogenic properties. They help to reduce stress by regulating cortisol (the stress hormone) production. Other components, such as fatty acids and antioxidants, promote cell regeneration, support immune function and improve physical endurance. Ashwagandha is also high in alkaloids, which can reduce anxiety and improve sleep quality.

What are the muscle-building benefits of ashwagandha?

  • Ashwagandha and strength gain: Ashwagandha increases strength. This is attributed to the plant's antioxidant properties, which optimise the muscular adaptation and recovery process, and therefore, increase muscular strength. [1] Ashwagandha contains withaferin A (a compound belonging to the withanolide family). This natural anabolic promotes myogenesis (the formation of muscle tissue) and oxidative metabolism (the conversion of food into energy) [2]. Although the mechanisms are still being studied, consuming ashwagandha can help you gain more strength when building muscle.

  • Ashwagandha and muscle recovery: Ashwagandha acts on different levels in regard to muscle recovery. It improves sleep [3][4]. This partly explains why it has been shown to reduce fatigue and promote muscle recovery. A balanced, restorative sleep allows for much more optimal and healthy physical activity. Ashwagandha also competes with cortisol (the stress hormone). Its levels rise significantly when we lack sleep. And, when cortisol levels are too high, muscle fatigue sets in. Better sleep, therefore, leads to a much more optimal recovery for trained muscles. What's more, taking an ashwagandha food supplement is thought to delay muscle fatigue. [1]

  • Ashwagandha and VO2 Max: VO2 max, or maximum oxygen consumption, is an indicator of the maximum amount of oxygen the body can use during intense exercise. The higher the VO2 max, the greater the efficiency of the cardiovascular and respiratory systems. Ashwagandha supplementation significantly increases VO2max in both beginners and experienced athletes. [5][6]

Why take ashwagandha for bodybuilding?

A course of ashwagandha can be beneficial during physical training, particularly for reducing stress and promoting muscle recovery. Thanks to its ability to significantly improve cardiorespiratory endurance [5], it is ideal when you are looking to improve your stamina or manage intense exertion more effectively. Similarly, by reducing stress and anxiety, it also has a beneficial effect on sleep. In a 2019 study, participants taking ashwagandha reported improvements in sleep quality, a reduction in the time it took to fall asleep and a feeling of better overall recovery. These results can be attributed to ashwagandha's adaptogenic effects, which regulate cortisol levels and promote a state of relaxation. This is conducive to restful sleep and reducing fatigue [3]

When should I take ashwagandha as part of my sports training?

Ideally, you should start taking ashwagandha a few weeks before a period of intense training. In addition to its beneficial effects on sports performance, taking ashwagandha before the start of a period of intense physical activity helps to reduce the risk of injury and excessive fatigue.

When should ashwagandha be taken?

To get the maximum benefits from ashwagandha during the day, we recommend taking it in the morning or at midday. To support muscle growth, improve sleep quality and boost your libido, we recommend taking it in the evening. You can also opt to take one capsule in the morning and one in the evening.
