According to the National Council on Aging, as many as 75% of Americans are chronically dehydrated. This widespread issue leads many to seek a quick fix, often wondering, "Does chugging water give you energy?" The truth is more nuanced, and while proper hydration is crucial for energy, the act of chugging water is not the answer and can even be counterproductive.

An extremely rare autosomal recessive metabolic disorder, dimethylglycine dehydrogenase (DMGDH) deficiency, is the true medical condition behind what is colloquially known as dimethylglycine deficiency. The key characteristic is not a simple nutritional shortfall, but a genetic inability to properly process the amino acid derivative N,N-dimethylglycine (DMG), leading to specific, identifiable symptoms.

According to the World Health Organization, iron deficiency affects billions globally, making it the world's most common nutritional disorder. This essential mineral is pivotal to muscular health, influencing everything from oxygen delivery to energy production and cellular function. A deficiency, even without anemia, can significantly hinder athletic performance and recovery.

Studies show that beta-alanine supplementation can increase muscle carnosine concentrations by as much as 80%. This is a key mechanism that explains what does beta-alanine do, primarily by buffering muscle acidity and delaying fatigue during intense exercise.

According to the World Health Organization, most Americans do not get the recommended daily magnesium intake. With magnesium involved in over 300 enzymatic reactions, this deficiency can often manifest as debilitating fatigue. Choosing the right form is crucial, as some are more bioavailable and targeted for energy production than others.

Creatine, one of the most popular and effective supplements for high-intensity exercise, is often associated with improving workout performance and delaying fatigue. But a common question that arises is whether this supplement actively works to reduce lactic acid, the substance long associated with the burning sensation in muscles. The reality is more nuanced, involving complex metabolic processes within your muscle cells.

Lactic acid is a naturally occurring alpha hydroxy acid (AHA) found throughout the human body and in fermented foods. Despite its ubiquity, many people question if lactic acid is safe, especially concerning its use in skincare and as a food additive, as well as its effects during exercise.

Despite decades of debunking, the myth that lactate is a harmful waste product causing muscle burn and fatigue persists, often cited even by sports commentators. This misconception fails to acknowledge the molecule's vital functions, which have been thoroughly researched and redefined by exercise scientists like George Brooks. The truth is that lactate is constantly produced and used by the body, serving as a critical fuel source and a powerful signaling molecule.

According to research, supplementing with beta-alanine can increase muscle carnosine levels by up to 80%. This non-essential amino acid is primarily known for its ability to enhance athletic performance by significantly reducing muscle fatigue during high-intensity exercise. But what does beta-alanine do for your muscles on a cellular level, and how can it impact your training?

Despite a common misconception, scientific evidence shows that beta-alanine does not directly remove lactic acid from your muscles. Instead, this non-essential amino acid plays a critical role by enhancing your body's natural buffering system to regulate muscle pH during high-intensity exercise.
