How to make collagen work faster

Not all collagen supplements are the same. Likewise, all our bodies are differentDon't expect a particular product to work on everybody. That said, there are some factors within our control.

Below are some of the ways you can optimise your collagen supplementation.

Take the right dosage for you: Like other supplements, there isn't a specific dose that works for the majority. Unfortunately, supplements aren't as regulated like pharmaceutical drugs. Nonetheless, there is a dosage range that has worked for the people in clinical studies and reviews. For most people, daily collagen of 10 to 20 grams is enough to experience significant improvementsYour diet critically affects your dosage. If you take less collagen-rich foods, the higher your dosage should be.  

Stay consistent with your collagen intake: Most people who take supplements aren't strict with their consumption. They treat them as one-time wonders and expert quality results. As with any other supplement, you must take your collagen peptides daily.

Eat a collagen-rich diet: Remember, supplements can never replace a good and balanced diet. If you feel you need this unique compound, take foods rich in collagen. Prime examples include bone broth, wildly caught fish, beef from grass-fed cattle, and chicken meat. Vegan collagen doesn't exist. Instead, we only have vegan supplements that boost the body's natural collagen production. Besides collagen, you'll also benefit from other proteinsEven though collagen is crucial, it still lacks one essential amino acid. Thou shall not live on collagen alone.

Choose the right collagen type that matches your needs: As you eat your natural protein-rich diet, you should take supplements with types of collagen peptides that address your issue. There are 28 types of collagen. However, collagen type I is the most abundant in the human body. Studies have shown that type II is best for joint health. For general full-body benefits, experts advise people to look for products containing types I, II, and III collagen.

How to choose the right collagen supplement

Always go for hydrolysed collagen from reputable brands.

Collagen is naturally a long-form protein with three amino acid chains. Your body can't efficiently digest and absorb it in that state. Therefore, quality brands usually break down the long protein chains to collagen peptides that are easier for the body to absorb.

Hydrolysed collagen supplements also reach the bloodstream faster since they avoid first-pass digestion.

While you are at it, look for quality collagen supplements with Vitamin C. Research has consistently shown that Vitamin C critically helps with collagen absorption.


There are a lot of factors that determine how long it will take to start experiencing collagen's benefits. We all have unique bodies that react differently to collagen supplementation. Also, the time frame will vary with your intended results.

Nevertheless, it will approximately take anywhere from six weeks to one year before you start noticing collagen’s benefits.
