Cosamin DS Review: Does It Really Work?

Cosamin DS Review

Cosamin DS For Joint Health immediately got our team’s attention due to outstanding ratings and great customer reviews. And since we are on a constant hunt for the best supplements, we couldn’t wait to grab our hands on it.

Did it manage to live up to its reputation? We are yet to find out.

Without further ado, let’s start with the review.

The Pros

  • Great ratings and customer reviews
  • Safe ingredients

The Cons

  • Pricey
  • Missing important compounds for joint health
  • The overall formula doesn’t seem effective

Cosamin DS Analysis Summary

Cosamin DS is far from a bad supplement. Unfortunately, it is far from a great one too.

As a whole, the formula is slim and contains well-researched ingredients. Glucosamine and chondroitin have a long history as joint health supplements. To make things even better, the dosages are on point.

However, there are just two active ingredients in the supplement. Glucosamine and chondroitin alone are unlikely to give you substantial benefits in terms of joint pain reduction.

There’s a lot missing from Cosamin DS, including some of the most important ingredients for joint health like Boswellia Serrata and MSM.

Unfortunately, the manufacturers didn’t manage to give us the best formula possible, even though it had potential.

Cosamin DS vs Glucosamine – What is the Difference?

Cosamin DS and Glucosamine are not the same. People often confuse these two terms, so it doesn’t surprise why it is one of the most frequently asked questions online.

Glucosamine is a compound that builds cartilage in the body and as it seems, its supplementation is beneficial for joint health. It is one of the main ingredients in Cosamin DS.

On the other hand, Cosamin DS is a supplement formulated to protect the joints and improve their function. Its formula consists of a combination of glucosamine, chondroitin, and manganese.

The bottom line is: Glucosamine is a single compound, while Cosamin DS is a joint supplement that contains glucosamine as one of its main ingredients.

Ingredients in Cosamin DS

Cosamin DS joint supplement facts

As already stated and as you can see from the image above, Cosamin DS contains three main ingredients:

  • Glucosamine HCI (1500mg)
  • Sodium Chondroitin Sulfate (1200mg)
  • Manganese (1mg)

Out of the three, the most effective ones for joint health are glucosamine & chondroitin. Therefore, our main focus will be on them.

Glucosamine Hydrochloride (Glucosamine HCL)

Glucosamine is a compound that gets derived from shellfish. It got a lot of public attention due to its benefits for joint health. As a result, you’ll most often see glucosamine being used in health supplements.

The studies so far show that glucosamine supplementation may reduce the rate of collagen degradation in the joints. As such, it may help with osteoarthritis.

However, glucosamine cannot be compared to osteoarthritis drugs. It is not as potent, and thus not as reliable for treating degenerative joint diseases. 

It cannot be nor should be a substitution for proper medical treatment.

However, to a certain degree, it can slow down the progression of the symptoms. Especially in the early stages of osteoarthritis.

Not many studies were done on glucosamine HCl since most of them focused on glucosamine sulfate. But from the available data, Glucosamine HCL could work just as well, although that’s still up for debate.

There is one study that found a combination of glucosamine HCl, chondroitin sulfate, and manganese ascorbate to be somewhat effective in individuals that suffer from mild to moderate osteoarthritis.

But overall, the available literature suggests very little benefit with the use of glucosamine HCl alone. That’s why we were disappointed to find out that Cosamin DS only has 2 active ingredients.

If you want to find out more about Glucosamine and its effectiveness in treating osteoarthritis symptoms, take a look at this study.

The dose of Glucosamine HCl in Cosamin DS is 1.5g (1500mg), which is also the standard dose used in the studies. 


Chondroitin is an ingredient that often comes alongside glucosamine. So it’s no surprise to see the two included in Cosamin DS.

Alongside glucosamine, chondroitin allegedly helps with joint pain, stiffness, and helps reduce other symptoms of osteoarthritis.

However, science doesn’t entirely agree with these claims. In fact, quite the opposite. 

For now, there is no solid evidence that proves chondroitin is beneficial for joint degenerative diseases.

According to, a recent analysis of data indicates that the studies done so far were poorly designed. Also, due to the small number of participants, they are not as reliable and have a greater chance of statistical error. 

Generally speaking, larger studies are much more reliable. However, they don’t go in favor of chondroitin either. They tend to show no benefits of chondroitin supplementation, neither in combination with glucosamine nor alone.

We cannot neglect the fact that a lot of people use chondroitin with glucosamine and report their symptoms going for the better. However, we also cannot look away from the fact that the current data doesn’t support any of these claims. 

So in that regard, chondroitin is a tricky one. Who to believe? 

Since we are big believers in science, we lean a little more to its side of the story. But what the future studies bring, we yet have to see. For now, chondroitin doesn’t seem like the most effective joint health compound.

In Cosamin DS, chondroitin comes in the dose of 1.2g (1200mg), which is the standard dose.

Side Effects – Is Cosamin DS Safe?

Cosamin DS should be safe and shouldn’t cause any adverse side effects. The ingredients are safe and don’t present a health risk.

On the internet, you can find numerous rumors that glucosamine causes hair loss. However, these claims are unlikely true.

That said, some studies reported minor and mild adverse events such as nausea, vomiting, and other gastrointestinal issues from glucosamine use.

But this is the case with almost any supplement. So generally speaking, Cosamin DS should be safe.

As we always say, if you are unsure whether this supplement may be safe for you, it’s best to talk to your doctor first.

How to Use Cosamin DS

Each day take three (3) capsules with a meal.

You can take each capsule separately or all at once. Take Cosamin DS as long as it takes to start working.

User Reviews

Cosamin DS has an outstanding rating on Amazon.

Its average rate is 4.8 out of 5, which speaks for itself. The fact that almost 90% of customers gave it 5 stars makes it even more impressive.

As with any supplement, there are always people who are unhappy with the product. However, only a tiny percentage of customers are dissatisfied with it. Only 1% of users gave Cosamin DS a 1-star rating!

In the comment section, the most common complaint is that the people were expecting the advertised double strength Cosamin DS, but got the “regular”.

However, other than the different writing on the label, we haven’t found any difference between those “two” versions. The dosages are completely the same. This means that some people have wrongly interpreted the label.

However, this is also a failure of the marketing team because it led to customer misconception, and this could have been easily avoided.

Some people also say that Cosamin DS was ineffective for them. Some say they had much more success when they switched to glucosamine sulfate.

This would be our main complaint too. Glucosamine sulfate is far better than glucosamine HCL and it’s too bad it didn’t find its place in Cosamine DS

Pricing & Where to Buy?

Cosamin DS is available at various stores. You can purchase it online or the old-fashioned way – directly from the store.

It is available on Amazon, Walmart, Costco, Walgreens, and others.

On the official website, you can find the full list of retailers. However, for some reason, you cannot purchase Cosamin DS directly from the official site.

From place to place, the prices of Cosamin DS vary quite a bit. The cheapest one we have found is at Costco for $39.99 for a 230ct bottle. In other places, the prices can go even up to $70.

Be careful where you purchase it so you don’t get ripped off the price!

Cosamin DS is available in bottles of 60, 108, 150, 210, or 230 capsules. The price will largely depend on the bottle size as well.

Final Thoughts on Cosamin DS

Despite the outstanding ratings and customer reviews, Cosamin DS is far from the most impressive supplement we came across.

It follows the pretty “standard” joint health formula with the combination of glucosamine, chondroitin, and manganese. So in that regard, it is not revolutionary.

However, if it works, it doesn’t have to be revolutionary! The most important part is that it is effective. But how well does Cosamin perform? Is it any good?

Unfortunately, we are not impressed.

Don’t get us wrong. It’s far from a bad supplement and contains promising ingredients.

But it only contains two active ingredients which makes it fall behind the leading joint supplements.

Would we recommend Cosamin DS? Not exactly.

It might be beneficial for some individuals, but in our opinion, it is too expensive to gamble.

For that price, there are much better choices on the market.
