GABA Product Buyer’s Guide (updated March 2025)

Metabolic Maintenance MetaCalm Review

MetaCalm comes from a well-established manufacturer, Metabolic Maintenance, which is backed by third-party monitoring services and manufactures its supplements in the United States. We like that this product contains clinically-proven ingredients and that the manufacturer is forthcoming with information about its products, whereas so many other manufacturers provide as little information as possible

MetaCalm has a comprehensive ingredient list that includes GABA, Vitamin B6, and L-Theanine. While these ingredients are beneficial for increasing GABA in the body, it is disappointing to note the lack of L-Arginine, which is such a crucial ingredient in allowing GABA to cross the blood-brain barrier and have maximum impact. Another major drawback of this product is the many ingredients added that do not have any influence on the effectiveness of GABA. 

It is promising that Metabolic Maintenance ensures that all their ingredients are third-party tested and all their products are manufactured following strict cGMP guidelines. However, they do not offer a money-back guarantee, which would show us that the manufacturers really back their product and its effectiveness.

Is Metabolic Maintenance MetaCalm Effective?

This product claims to provide the amino acid building blocks, vitamins, and minerals to help the body synthesize mood-enhancing and calming neurotransmitters. It does contain GABA, L-Theanine, and Vitamin B6, which are well-known for providing these benefits. However, it is lacking L-Arginine, which is vital for ensuring that GABA can cross the blood-brain barrier where it can be used. We really like how transparent the manufacturer is about their product; they provide sufficient information about how the product works and where they have sourced their ingredients from.

There aren’t any customer reviews present on the product website, nor were there many written reviews on a third-party website. From the small number of reviews that we did see, many customers seemed satisfied with their purchase, but there were also some customers that were not impressed with the results. 

Bottom Line: Even though Metabolic Maintenance MetaCalm is good, it could be better. It contains effective ingredients, but it could contain more which would potentially increase its effectiveness and also give it a better standing with consumers. We like that it appears to be a high-quality product that undergoes third-party testing and follows cGMP guidelines.

Is Metabolic Maintenance MetaCalm Safe?

We did not find any ingredients in this product that would cause it to be unsafe, and it should not cause any harm if taken according to the manufacturer’s instructions. MetaCalm is also egg, gluten, nut, and dairy-free, making it a safer choice for consumers with certain allergies.

As with any supplement, we advise that you consult with your doctor, especially if you are pregnant, breastfeeding, or on any other medication.

Summary

Metabolic Maintenance had the right idea in making MetaCalm with GABA, L-Theanine, and Vitamin B6. That said, without the addition of L-Arginine it is difficult to say whether this product gives an efficient GABA boost. We like that this manufacturer strives to provide excellent products by doing research and providing customers with sufficient information. We also like that all of the ingredients have undergone third-party testing and that all their manufacturing follows cGMP guidelines. Despite all this, there is no money-back guarantee, which could be an indication that the manufacturer doesn’t back their product as being truly effective.
