Anti-aging supplements: Benefits, types, dosage, side effects

The quest for the fountain of youth has been an ongoing human endeavor throughout history, driving a whole new market segment – the anti-aging supplements industry. 

Today, these supplements promise to slow down the hands of time, giving us a renewed lease on life by keeping the signs and symptoms of aging at bay. But with this comes the inevitable questions. 

What benefits do these supplements offer? What types exist in the market, and what are their ideal dosages? Are there any side effects, and how can we manage them? And finally, amidst the many options available, how does one choose the right anti-aging supplement? 

In this article, we will take an in-depth look into the world of anti-aging supplements, providing answers to these questions and guiding you toward a decision that best suits your needs.

How does the biological process of aging work?

The aging process is a natural and inevitable biological occurrence affecting all living things. As we age, our bodies undergo various changes [1]. These changes are not merely external, like the development of wrinkles and gray hair, but internal as well. Our organ systems gradually decline in functionality, affecting processes like metabolism, cognitive function, and immunity.

At a cellular level, aging is characterized by several changes. Our cells experience DNA damage, accumulation of harmful substances, reduced cellular division, and decreased functioning of mitochondria – the cell’s powerhouse. 

Oxidative stress, a condition resulting from an imbalance between free radicals (harmful compounds) and antioxidants in your body, also plays a significant role in the aging process. This oxidative stress can damage our cells’ structures and impact their function.

Simultaneously, the length of telomeres – the protective ends of chromosomes that safeguard our genetic data – shortens over time. When telomeres become too short, cells lose their ability to divide and renew, leading to aging and disease.
