Optimum Nutrition need no introduction to you, they are industry GIANTS. And makers of some of the best supplements on the market.

But is Opti-Lean one of those supplements? Or is this product just a side thought they’d have to get into the market.

When you’re cutting fat you need a natural product, clinically dosed and with proven ingredients only.

Opti-Lean looks to tick a few of those boxes and does feel like a solid fat burner.

But is it going to be enough to take on your favourite proven fat burners?

Optimum Nutrition Opti-Lean Fat Metaboliser Core Ingredients

Fat Burning Ingredients Index

The blend in Opti-Lean uses herbs, amino acids and vitamins to help boost metabolism and use stored fat as energy.

The doses look fairly solid and the ingredients list clean and safe, this is a strong start for a cheaper product on the market.

Often though, cheaper products are slightly under dosed in terms of their serving size, requiring a couple more capsules to ensure fat burning success through the day.

L-Carnitine

L- Carnitine is great for heart health. In particular blood vessel health and heart rhythm. It has also been shown to help those with a high cholesterol and triglyceride count.
On an athletic level, L-Carnitine can both optimise performance and increase fat burning. It carries fat directly to the mitochondria where energy is produced.
Generally L-Carnitine is better at higher doses in supplements, so is often under dosed in fat burners.

Green Tea

Green Tea is very popular amongst health and fitness enthusiasts in recent times. Especially as it has been found that when combined with caffeine, it can boost your metabolism far beyond what caffeine can do alone.
Studies have shown that it can increase your metabolism to the point of burning an extra 200 calories a day without added exercise. 500mg of Green tea is perfect in a fat burner.

Caffeine

Caffeine is a staple supplement to modern day life. It is a highly effective stimulant in how it boosts the metabolism, mobilises fat to be used as energy and suppresses appetite.
As well as this it can boost the effects of other metabolism boosting products, such as green tea or bitter orange.
It has long been used by athletes, and non-athletes alike, in order to increase alertness, endurance and longevity.
This is essential for a fat burner. You need around 250mg-300mg dosed evenly through the day for best results.

Cayenne

Cayenne Pepper is a species of pepper native to the Americas. It is a key element in various cuisines but is now often used as a supplement.
Cayenne Pepper contains capsaicin which is known for its “warming effect.” It is known for its positive effects on healthy blood circulation throughout the body. This ingredient has been proven to burn calories in fat burners. 100mg through the day is an ideal amount.

Guarana

Guarana is an incredibly effective stimulant. Its seeds contain more than double the caffeine found in coffee seeds.
Guarana contains 2-4.5% caffeine in its seed, whereas coffee only contains 1-2%.
Due to its high content of caffeine it is proficient in boosting the metabolism and increasing mental alertness.
Guarana can cause side effects due to it’s caffeine content and shouldn’t be mixed with other stimulants.


Optimum Nutrition Opti-Lean Fat Metaboliser Dose

The dose in Opti Lean is pretty low generally, but it’s safe.

If you are serious about losing fat you need to be supplementing at least 3+ capsules per day.

This will ensure an increased metabolism and energy through the periods you are burning the fat too.

There’s also limited dietary support in Opti Lean. Which is a little frustrating.


Optimum Nutrition Opti-Lean Fat Metaboliser Side Effects

Generally you shouldn’t get any side effects from this product. It’s natural, clean and dosed on the lower side of fat burners in each capsule.

This product is probably suited best for people with a low tolerance to fat burners and who don’t want to commit to a full course.


Optimum Nutrition Opti-Lean Fat Metaboliser Review Conclusion

This is a safe, fairly weak and affordable approach to fat burning and something that would work well if you are new to fat burning and fitness.

If you are serious about getting results there are far better products on the market that will guarantee success due to a higher and better dosing structure and serving size.

It’s also the case that you need more proven ingredients if you are serious about cutting away that fat.
