Overview of DMHA and DMAA

Definition and Origin

Dimethylhexylamine (DMHA), initially utilized as a nasal congestion drug, has transitioned into a popular ingredient in dietary supplements aimed at enhancing workout performance, fat burning, and weight loss. Despite its widespread use, scientific research validating these benefits is scarce. Claims of DMHA originating from aconite plants lack evidence, suggesting that DMHA in supplements is likely synthesized in laboratories rather than derived from natural sources. Similarly, dimethylamylamine (DMAA) shares a background as a stimulant once removed from markets in certain countries due to safety concerns. Both DMHA and DMAA, having been explored initially for their decongestant potential, are now recognized for their roles in “hardcore” pre-workout supplements, despite the absence of approval from regulatory bodies like the FDA.

Mechanism of Action: Stimulating Effects

DMHA and DMAA function by inhibiting the reuptake of dopamine and norepinephrine, neurotransmitters responsible for feelings of euphoria and wakefulness. This inhibition elevates the concentration of these neurotransmitters, enhancing motivation, euphoria, and alertness. The main distinction between the two compounds lies in their potency; DMAA is stronger on a per-milligram basis compared to DMHA, necessitating higher doses of DMHA to achieve similar effects. Both substances are known to cause vasoconstriction, affecting cardiovascular activity and potentially increasing muscle blood flow during exercise while also raising blood pressure. These effects categorize them as pressor amines, a group that has been of interest since the introduction of ephedrine in the 1920s.

Common Uses in Pre-Workout Supplements

In the realm of dietary supplements, DMHA and DMAA have found their place predominantly in products labeled as pre-workouts, weight-loss aids, and “fat burners” due to their supposed benefits like appetite suppression and energy enhancement. Despite their popularity, the FDA has deemed DMHA as a new dietary ingredient lacking evidence for safe use, rendering supplements containing DMHA as adulterated. Similarly, DMAA, despite its stimulant effects that may increase focus, alertness, and energy levels during workouts, faces regulatory challenges due to its potential for misuse and associated health risks. The allure of these compounds in enhancing workout performance and energy levels has led to their inclusion in the most “hardcore” supplements, often under different ingredient names to evade regulatory scrutiny. However, both DMHA and DMAA are banned by WADA and are not approved for inclusion in dietary supplements, underscoring the importance of caution and informed decision-making among consumers.

Benefits and Efficacy in Enhancing Workout Performance

Energy Boost

Both DMHA and DMAA are known for their potent effects on increasing energy levels by inhibiting the reuptake of dopamine and norepinephrine, neurotransmitters that contribute to feelings of energy, alertness, and euphoria. This mechanism increases the concentration of these neurotransmitters, thereby enhancing the feelings of motivation, euphoria, and wakefulness which are crucial for intensive workouts. Studies have shown that DMAA-based dietary supplements can stimulate the central nervous system, increasing blood pressure and releasing adrenaline, which significantly contributes to increased energy levels and aids in exercise performance. DMHA similarly provokes energy through our risk and reward system by increasing the uptake of dopamine and norepinephrine.

Focus and Concentration

The heightened focus and concentration provided by stimulants like DMHA and DMAA are highly valued by athletes and fitness enthusiasts. This is largely due to the increased levels of dopamine and norepinephrine, which are essential for enhancing motivation and the desire to act, thereby improving performance in the gym. Anecdotal evidence suggests that users experience a “wicked strong focus” and a notable kick of motivation with DMHA, while DMAA is associated with a more euphoric kick and the ability to sustain prolonged gym sessions. The combination of DMHA with Eria Jarensis, another stimulant known for strong motivation and mood boost, is reported to produce effects very similar to DMAA, emphasizing their role in enhancing mental and cognitive performance during training.

Strength and Stamina

While the direct impact of DMHA and DMAA on strength and stamina is more challenging to quantify, the overall enhancement of workout performance is evident through increased energy, focus, and reduced fatigue. The use of pre-workout boosters (PWBs) containing DMAA or similar agents has been significantly associated with increased mental performance capacity, which can indirectly contribute to better strength and stamina during workouts. The ability of these stimulants to reduce fatigue caused by prior training sessions and facilitate mental and cognitive performance is crucial for athletes aiming to push their limits in the gym. Additionally, the sympathomimetic effects of DMAA, which mimic neurotransmitters in the sympathetic autonomic nervous system, prepare the body for physical exertion by redirecting blood to essential areas during heightened physical demands, thus potentially enhancing strength and stamina.

In summary, DMHA and DMAA pre-workout supplements offer significant benefits in terms of energy boost, focus and concentration, and potentially improved strength and stamina. However, it’s essential for users to consider the dosage and safety profiles of these compounds, as their potency and effects on the central nervous system can vary.

Potential Side Effects and Safety Concerns

Cardiovascular Risks

DMAA, an amphetamine derivative found in some pre-workout supplements, poses significant health risks, especially when combined with stimulants like caffeine. This combination can elevate blood pressure and lead to various cardiovascular issues, ranging from minor symptoms like shortness of breath and chest tightness to severe conditions such as heart attacks. The FDA has highlighted the absence of evidence supporting the safety of consuming DMAA, considering products containing it as unsafe food additives. The agency has expressed deep concerns about DMAA’s vasoconstrictive effects, which can dangerously increase blood pressure and potentially result in cardiovascular problems, including arrhythmias, heart attacks, and even seizures.

Similarly, DMHA, despite being promoted as a safer alternative to DMAA and ephedrine, is considered possibly unsafe when consumed orally. It shares similar side effects with DMAA, including the risk of heart attack and death. Individuals with high blood pressure are advised against taking DMHA due to its potential to increase blood pressure further. Additionally, its stimulant effects can lead to rapid heartbeat and worsen heart arrhythmias, posing a significant risk to individuals with irregular heartbeats.

Neurological Effects

The stimulant effects of DMHA and DMAA extend beyond cardiovascular risks, impacting the nervous system. These substances can cause a variety of neurological and psychological conditions, such as seizures and other serious issues. The FDA warns against the use of DMAA due to these potential health risks, emphasizing the need for consumers to avoid products containing this substance.Furthermore, the stimulant properties of DMHA might interfere with surgery by increasing heart rate and blood pressure, necessitating cessation at least 2 weeks before any scheduled procedures. The combination of DMHA with other stimulant drugs could lead to severe problems, including increased heart rate and high blood pressure, highlighting the importance of avoiding such combinations.

Regulatory Status and Legal Issues

The legal status and regulatory scrutiny of DMHA and DMAA underscore the concerns regarding their safety. The FDA considers both DMHA and DMAA as substances that do not meet the statutory definition of a dietary ingredient, rendering them unsafe food additives. Consequently, dietary supplements containing DMHA or DMAA are deemed adulterated under the Federal Food, Drug, and Cosmetic Act (FD&C Act). Over the years, the FDA has taken various actions to ensure that DMAA-containing products are removed from the market to protect consumers. Warning letters sent to several companies by the FDA allege that their dietary supplement products containing DMHA or DMAA are adulterated and/or misbranded, violating the FDCA. The mere presence of either ingredient in a dietary supplement product renders it unlawful, as neither is considered a “dietary ingredient” under the Dietary Supplement Health and Education Act (DSHEA).

Despite the FDA’s position, the safety and legal status of these substances remain subjects of debate. The absence of allegations regarding the unsafe nature of these ingredients in some warning letters does not negate the potential health risks associated with their use. The regulatory actions taken against DMHA and DMAA-containing products highlight the importance of consumer awareness and caution when considering the use of pre-workout supplements containing these compounds.
