The use of natural dietary supplements such as Tongkat Ali and Ashwagandha is increasingly popular among active members of the military and active-duty soldiers to improve endurance, strength, alertness and regulate stress.
While vitamins, minerals and pure herbal supplements are generally acceptable, US, UK and Australian military impose strict guidelines on the use of dietary supplements, especially products that may contain banned or potentially harmful ingredients.
This article explores whether Tongkat Ali, Ashwagandha, and other dietary supplements are permitted in the military, with specific guidelines from the US Defense Department, UK Armed Forces, and Australian Defense Force.
Additionally, we’ll cover banned substances often found in dietary or herbal supplements to ensure military members remain within regulatory boundaries and safety.
1. Overview: Supplements in Military Service
Dietary supplements, including herbal products and performance enhancers, are often sought by military personnel and soldiers to improve endurance, strength, focus, and recovery.
Studies showed 70% of military personnel and active soldiers use some form of dietary supplements, vitamins, minerals, antioxidants, fish oil and herbal products more than once a week – albeit higher consumption than the general public.
Many European countries, like Germany and France, permit the use of herbal supplements in their militaries, emphasizing the importance of transparency and regulation, but the US and UK Armed Forces and Australian Defense Force have strict regulations on the use of dietary supplements to ensure safety to their members and army personnel.

Amongst the dietary supplements used by the military, Tongkat Ali (Eurycoma Longifolia) tops the chart as energy performance booster, widely popular amongst the members of the US Armed Forces (Marine Corps, Navy SEALS,) as it is not banned by the US Department of Defense (DOD).
Tongkat Ali is not on the US Department of Defense (DOD) Prohibited Dietary Supplement List and should not cause a positive military drug test
Developed by the MIT scientists since 2003, standardized Tongkat Ali hot water extract was made available in the US market in late 2020, primarily to provide optimal testosterone and energy support – which are helpful for hard military training, on-ground combat and for active-duty soldiers to improve focus and regulate stress, especially during challenging military operations.

Combining Tongkat Ali with multivitamins showed a 581% in total testosterone which may benefit military personnel to improve endurance and stamina
Many military personnel have showed improved resilience, grit and stamina from increased testosterone when taking dietary supplements – typically a combination of vitamins (i.e Vitamin C, D, B12, zinc, magnesium), minerals (sodium, potassium and calcium) and natural herbs such Tongkat Ali.
In the UK, Tongkat Ali and Ashwagandha are not banned but the use of dietary supplement by British Army is “not encouraged” according to the official statement by the UK Armed Forces on drugs and dietary supplements.
According to a military health expert, the trend of having a supplement stack or buying untested products carries certain risks, from potential side effects to the presence of banned ingredients that could jeopardize military readiness.
According to the Pentagon bureau chief at Military Times Meghann Myers, the US Defense Department has issued an instruction that governs the use of dietary supplements among military personnel and members, and bars any on-base retailers from selling dietary products with any banned ingredients.

2. Guidelines for Supplement Use in the US Defense Army / Military
In the US, the Department of Defense (DoD) provides clear regulations on supplement use, encouraging service members to research products before use. Here are key points:
- Safety and Efficacy: Supplements like Tongkat Ali and Ashwagandha may be allowed but should be selected with care. Always purchase 3rd party lab tested Tongkat Ali products from independent organizations such as EUROFINS or Informed Sports to avoid the addition of adulterants or anabolic steroids.
- Potential Banned Ingredients: If a supplement contains banned or unapproved ingredients, it is prohibited for military use. Substances like certain anabolic steroids, DMAA, ephedrine, and SARMs (selective androgen receptor modulators) are restricted due to their potential to impair readiness and cause health complications.
- Monitoring Tools: The OPSS provides a “High-Risk Supplement List” and a Supplement Safety Scorecard, helping military members assess whether a supplement is safe or permissible. Tongkat Ali, for instance, might be considered acceptable, provided it is free from prohibited substances and taken within recommended dosages.
The DoD remains vigilant about supplement use, and service members are urged to seek medical guidance and consult with their commanding officers if they have doubts about a specific product’s legitimacy.
3. UK Armed Forces’ Approach to Dietary Supplements
The UK Armed Forces implement stringent guidelines regarding supplement use to maintain operational readiness and health. Here’s how the UK regulates the use of dietary supplements by the British Army:
Developed by the MIT scientists in its early days, standardized Tongkat Ali hot water extract helps optimal testosterone support during hard military trainings, combat and beneficial to active-duty soldiers improve focus and regulate stress during challenging military operations.
- Health & Performance Monitoring: The British Army’s Health and Performance Department offers guidelines on supplement use, advising personnel to prioritize diet and training over supplements. According to the official UK Army website, individuals should avoid supplements with unregulated substances that can appear on anti-doping tests, which may lead to disciplinary actions or discharge.
- Restricted Substances: While Tongkat Ali and Ashwagandha is not in the banned list, the UK Armed Forces enforces restrictions on performance-enhancing drugs and specific stimulants that may pose health risks or lead to impaired judgment in the field. Members are advised to stay updated on regulations, particularly with evolving supplements on the market.

For members of the UK Armed Forces, thorough research and adherence to dietary guidelines are essential to ensure all supplement use aligns with military standards.
4. Australian Army’s Rules on Supplement Use
The Australian Army upholds a cautious approach to dietary supplements, emphasizing natural fitness regimens and balanced nutrition. However, studies showed 74% of Australian army personnel use dietary supplements at least once daily, so you still can buy the dietary or herbal supplement if you are an active on-duty soldier in Australia.
Here’s what Australian soldiers and military personnel should know:
- Focus on Evidence-Based Choices: The Australian Army emphasizes the importance of choosing supplements with proven, evidence-based benefits while avoiding products with stimulant or anabolic effects. If herbs is your top choice, Tongkat Ali and Ashwagandha are backed by growing clinical trials and scientific evidence to support strength, testosterone and stamina.
- Use of Traditional Herbs: Though traditional herbs like Tongkat Ali and Ashwagandha are not outright banned by Australia Army, military personnel are advised to check with a medical professional and seek approval if these products could interfere with duty performance or contain unverified or banned ingredients.

Make this your preferred choice when choosing dietary or herbal products such as Ashwagandha.
In the Australian military, safety and transparency in supplement use are paramount. Like the US and UK forces, consulting healthcare providers before starting any new supplement is advised.
5. Banned Substances in Military Supplements
Using dietary supplements that contain banned substances can result in serious consequences for military personnel, including disciplinary actions or discharge.
Here are some common banned substances across the US, UK, and Australian militaries:
- Stimulants: Compounds like DMAA (dimethylamylamine) and ephedrine are strictly prohibited due to their impact on the cardiovascular system, which can lead to heightened blood pressure and, in extreme cases, heart failure.
- Anabolic Steroids and SARMs: Ingredients like anabolic steroids or SARMs are banned in most military branches because they affect hormone levels, often leading to negative long-term health effects. SARMs can be found in some bodybuilding supplements but should be avoided by all military personnel.
- Amphetamines: Used as a stimulant in some weight-loss supplements, amphetamines are banned because they impair judgment and pose risks to mental stability. Such effects can reduce operational readiness and may also show up in anti-doping screenings.
- Synthetic Cannabinoids and Opioids: Synthetic cannabinoids, sometimes marketed as “natural,” are illegal due to their hallucinogenic properties and effects on mood. Certain opioids and opioid-like compounds can similarly disrupt focus and physical coordination, compromising safety in critical situations.
Warning:
- Stimulants, anabolic steroids, SARMs and amphetamines could exist even in Tongkat Ali or Ashwagandha supplements that are not 3rd party tested. Always purchase Tongkat Ali, Ashwagandha or herbal products that are pure, natural and 3rd party lab tested by reputable organizations such as EUROFINS.
- To stay safe and compliant, personnel should cross-reference any supplement against the OPSS database and similar resources provided by their respective military health departments to ensure no banned substances are present in your dietary or herbal supplements.
6. Practical Tips for Military Personnel Using Supplements
If you’re considering taking supplements like Tongkat Ali or Ashwagandha, here are some practical guidelines to help you make safe choices:
- Consult a Military Health Professional: Always seek guidance from a healthcare provider or military-approved nutritionist, as they can provide personalized advice and help avoid any banned substances.

Lab tested Tongkat Ali products which are certified by EUROFINS are trusted amongst military personnel as it complies to toxicity, safety and free from drugs or banned substances in the military list.
