Side Effects of Peptides

Peptides are just a shorter form of protein. Made up of smaller links of amino acids, peptides affect the body in different ways. While there are numerous positive effect of peptides from it aiding anti-aging to improving muscle recovery. Numerous studies have been conducted to gauge the impact of peptides on aging. Collagen peptide in a study showed to reduce wrinkles when partnered with a proper nutrition and vitamins. There are also quite a few side effects from the use of peptides that individuals should be aware of.

Remember when you introduce almost anything new to your body that is not naturally produced there will be some negative reaction to it.

Negative Impact of Peptides

  • Liver damage, if peptide supplement is not monitored properly it can lead to protein poisoning which can damage the liver. Introducing too many peptides to the body leads to protein poisoning as the presence of too many amino acid has a negative impact on the liver.
  • Most bodybuilders introduce synthetic peptides to the body as it aids in muscle recovery and strength. However, this causes a bit of inconsistency in the speed at which the muscle and the ligament grows. Which can lead to serious injuries and a growth in the muscle that may not be consistent.
  • Everyone reacts differently to the introduction of peptides to the body. While some have a positive reaction to peptides, it may have negative reaction based on the individual.
  • Appetite decreases, peptides give individual sort of a sense of joy while also suppressing their appetite. This is a major reason why they are considered wonderful for fat loss. However, this is not always a good thing depending on the body type of the person, it is important to have healthy and normal eating habits.
  • There are numerous different peptides that are available. Most have mild side effects such as headache, nausea, irritation of the skin, and so on.

Peptides aren’t all amazing. It is important to know both the positive and negative of a supplement before you take it. While studies are still being conducted on peptides as doctors and scientists aim to get to know more about peptides. From what studies have already learned peptides can be beneficial however, it is important to not over do it. You must approach them with precaution as introducing anything new to the body that is not natural can have a negative impact on it.


Difference Between Peptides and Protein

When it comes to the human cell, both protein and peptides are a major component that aid in carrying out the biological function of the cell. If we look at the structure of the two, they are quite similar. Both are made up of chains of amino acids. Proteins have a role in the shape of a cell and responding to signals from extracellular environment. Peptides play a role as far as regulating activities of other molecules.

How the two differ?

While both peptides and protein are formed from amino acids their structure and size differs. Peptides are much smaller in size. They are made up of a chain of 2 to 50 amino acids. Peptides are also are not as defined as protein structurally. Proteins start from a chain of 50 amino acid chain and are complex. They can form structures from secondary to quaternary, peptides do not.

The two also differ in term of function, this solely depends on the type of protein and peptide.

  • Peptide are shorter in size than proteins.
  • Peptides help form protein, several peptide can be linked together to form protein.
  • Protein have 3D structure while peptides do not.
  • Proteins are considered to be macromolecules whereas peptides are not.


While the two may differ, they both are similar in the sense that they are made by linked amino acids. Both also play a major role in the biology of the body as they are a major component in the cell. Science has been studying the impact of both on the human body. Protein has become a major building block in muscles. Many bodybuilders rely on high intake of protein to help them recover and build stronger muscles. In the same way, peptides are also gaining a lot of steam with body builders as they are known to speed up recovery and also aid in building stronger muscles. This is no surprise as they are also made up of amino acids.

So while they may differ, the two also have some functional similarities and play a vital role in the biological makeup of the body. You must remember that there are numerous different type of proteins and peptides which serve different functions. So to ensure you get the most out of either protein or peptides, you must know which one is best suited for the purpose you need.
