NMN Product Buyer’s Guide (updated July 2024)

ForestLeaf NMN Review

ForestLeaf is a supplement brand that sells various nutritional supplements. They are based in the USA and have the proper certification to ensure their products are safely manufactured. ForestLeaf NMN is vegetarian and third-party tested. We were impressed that the absorption of this product has been tested as many supplement suppliers forget to factor absorption into their formulation.

Well this product may seem to have an appealing price of only 40$ a bottle, it is actually more expensive than our top pick in the long run. Each bottle of ForestLeaf NMN contains 60 pills of 175mg each. A serving size is 250mg which means 2 capsules are needed per serving. At this rate, there is a month’s supply in each bottle. However, the manufacturer does state on the label that individuals can take up to 8 capsules a day, meaning that it could take less than a month to consume a whole bottle.

If you were to take 2 servings daily, meaning 4 pills a day, so that you can consume 500mg NMN daily, then a bottle would only last about half a month. This means that you would need to spend $80 a month to take ForestLeaf NMN at an optimal dosage of 500mg. Well this is still cheaper than many NMN supplements out there, it is more expensive than our top pick and requires you to take more pills throughout the day and who wants to feel like they are constantly popping pills? 

Is ForestLeaf NMN Effective?

The first way we can judge efficacy is by the ingredients. With 250mg NMN per serving, we don’t know that it is really enough to experience any benefits. As explained above, there is the option to take multiple servings to get results.

Since this product does contain NMN, we believe that when taking 500mg a day, a person will experience benefits. However, our main concern is that the NMN used is not patented and is not the highest purity NMN. There is also no BioPerine® to increase nutrient absorption although ForestLeaf claims their pills are tested for quick absorption.

Another concern is that NMN is not always stable and can therefore lose potency due to temperature or the passage of time. Whereas our top pick can be stored at room temperature, this product should be stored in a “cool, dry place.” In addition to affecting potency, this makes it more difficult to take servings throughout the day as the pills cannot be easily packed in a purse or pocket.

Lastly, we also examined reviews to gain insight into how effective a product is. While some people voted lower than 5 stars, almost all of the written reviews were positive and gave a high rating.

Is ForestLeaf NMN Safe?

In general, ForestLeaf markets this product as natural and safe. There are no mentioned side effects. The manufacturer upholds the standard GMP practices and the product undergoes internal and third-party testing.

As a general rule, it is always recommended to speak to your doctor before taking any new supplement, especially if you are pregnant, nursing, have any health conditions, or are taking other medications.


ForestLeaf NMN appears to be cheaper than many NMN products on the market but that is largely due to a smaller serving size. The NMN included in these capsules is not the highest purity, most-stable NMN but people who use this product seem to be happy with the results. There is a claim that this product comes with a 60-day satisfaction guarantee but the manufacturer’s returns page makes no mention of it and we could not find details elsewhere either. This product is GMP certified, third-party tested, and made in the USA.  If we didn’t know that we could get better value for our money with Approved Science NMN, we might be tempted by ForestLeaf NMN.
