Optimum Nutrition Tribulus 625mg Review – Should You Consider It?

When it comes to supplements that help you with your workouts and boost testosterone and libido there are a lot of them to consider. Optimum Nutrition Tribulus Capsules are one of these products. The only drawback you can tell right away is that the supplement facts state only one ingredient and that is Tribulus Terrestris.

This ingredient is a common one in testosterone-boosting supplements, but the research doesn’t show any promise of gaining those T levels. What you can expect is a slight increase in libido that could also somewhat affect your workouts in a positive way.

The Good

  • Only 1 plant meaning it specifically tackles a small area of problems
  • Low price
  • Natural ingredient
  • 1 package will last you a long time
  • Widely available
  • Easy to take

The Bad

  • Only 1 plant meaning it specifically tackles a small area of problems
  • You will need to take other supplements if Tribulus doesn’t tackle all the problems you are looking to fix


We found ON Tribulus to be a good Tribulus product but don’t expect miracles from a single compound. It’s missing quite a few important ingredients as far as testosterone and libido boosting goes. There are better options available with a little research.

About Optimum Nutrition Tribulus 625mg

Optimum Nutrition Tribulus Terrestris capsules 635mg are a product for people that want to improve their workouts, increase testosterone as well as boost their sexual drive. Today we will be taking a closer look into how Tribulus Terrestris works and if it can deliver what the manufacturer promises.

How to Use About Optimum Nutrition Tribulus 625mg

The consumption of ON Tribulus is rather simple. The official website of Optimum Nutrition recommends you consume 2 capsules of this supplement with a meal. If you are just starting to take this supplement you can also consume 1 capsule a day for starters in order to see how your body reacts to Tribulus, taking the dose to 2 capsules a day after a short period.

The Supplement Facts of every product are the most important part as it shows us what we can really expect from a product. ON Tribulus is rather simple as it contains only one proprietary blend so let’s look into what Tribulus Terrestris has to offer us.

Proprietary Tribulus Blend

When it comes to this blend we get Tribulus Terrestris Extract and Tribulus Terrestris powdered, both fruit. When it comes to Tribulus Terrestris from the existing research the fruits from the plant appear to protect the organs(mostly kidneys and liver) from oxidative damage, boost libido as well as show anti-stress effects.

Now comes the highly debated subject. Does Tribulus Terrestris help with workouts, and does it boost testosterone?

Well, the short answer is no, but it’s more complicated than that. The existing research fails to support these claims(more so for the testosterone boosting claim) but it is important to mention there needs to be more research done to be a hundred percent sure. If we take a deeper dive we can see that this plant has been used for a really long time in traditional Indian medicine as a libido enhancer and organ protector.

Anything Missing?

It’s hard to say if anything is missing in a product that only has one ingredient, but just like a Vitamin D supplement will help you, it will only help you in one field and you’ll need to take another supplement if you are trying to better something else simultaneously. Therefore if you are looking for a more complex product that will bring you many benefits associated with higher testosterone you should look into alternatives.

Customer Reviews of ON Tribulus

The customer reviews we have gathered are mostly positive. We can see a recurring pattern, and that is users saying that they have seen an improvement in their workouts and health from taking Optimum Nutrition Tribulus. We’ll put a few reviews below.

Side Effects

There shouldn’t be any side effects from taking Optimum Nutrition Tribulus. If you’re really unlucky the worst you should experience is stomach pain, cramping, or diarrhea although we haven’t found too many users reporting they experienced this.

Price and Value for Money?

You can get Optimum Nutrition capsules directly from optimum Nutrition, Amazon, or Walmart. The price might slightly vary, but it should be around $16.99. We should also mention that you can often find discount codes for the sites so the price will be even lower.

This price is for the 100 capsules and that means if you are taking 2 capsules daily the cost per day is $0.339 which sounds great but keep in mind that this is only one ingredient and if you are tackling more than one health problem you will need to take another supplement so that can add up and it can become more expensive than finding a supplement that will help you with all of your needs at once.

Conclusion to Optimum Nutrition Tribulus Caps Review

Optimum Nutrition Tribulus is a plain and simple product that can be great or not so great depending on what you need.
