Magna Force Plus: An Evidence-Based Review


Magna Force Plus is a supplement that is supposed to enhance workout performance and help you gain lean muscle.  Well, this all sounds great, but does it actually work?

If you google Magna Force Plus, what you’ll find are a bunch of conspicuously sparse “review” websites that don’t seem to have any other content besides the Magna Force Plus review.  If you land on one of these sites and scroll down the page, you’ll come to an advertisement enticing you to buy the product.  It might say something like “Start Your Free Trial!” or “Hurry! Supply Is Low”.  If you click on that ad, you’ll be redirected to the Magna Force Plus site which is essentially just another sales pitch page and a payment portal for you to fork over your hard earned money…

But before you go and do that, let’s take a look at the ingredients in Magna Force Plus…

Magna Force Plus Ingredients

The first bad sign here is that the Supplement Facts panel for Magna Force Plus is impossible to find.  There are a ton of sites that offer “information” about Magna Force Plus, and some of them list the ingredients, but none of them show a Supplement Facts panel with the doses of each ingredient.

The ingredients that are supposedly in it are:

  • Agmatine
  • Citrulline
  • Norvaline
  • Arginine
  • Maca

Of course, because we don’t know the dose of any of the ingredients, we can’t be certain how effective any of them are.


Agmatine is a metabolite of the amino acid Arginine which has been shown, in vitro, to activate Endothelial Nitric Oxide Synthase (eNOS), an enzyme which triggers the production of Nitric Oxide.  More Nitric Oxide theoretically increases blood flow to the muscles, leading to performance enhancement and better recovery.

However, Agmatine has never been studies in humans.  The results obtained in mice or in cells under a microscope are not necessarily indicative of what might happen in humans.  Anecdotal evidence suggests that Agmatine is effective at producing a good pump, but again, that’s anecdotal evidence.

The truth is there’s just no scientific research backing Agmatine as a performance enhancement agent.  In the context of Magna Force Plus, it’s probably not doing much.


Citrulline is an amino acid that serves as a precursor to Arginine which in turn converts to Nitric Oxide.  Unlike Agmatine, however, Citrulline has been studied extensively in humans and shown to actaully boost Nitric Oxide and improve exercise performance.

Unfortunately, since we don’t know how much Citrulline is in Magna Force Plus, we really can’t be sure how effective it is.


Norvaline is an alternate form of the amino acid Valine which has been shown, in vitro, to inhibit Arginase, the enzyme that breaks down Arginine.  Theoretically, by reducing Arginine breakdown, Norvaline may increase Nitric Oxide levels.  However, no human studies have ever confirmed this or identified any sort of effective range, so dosing is hit or miss.

Norvaline may or may not do anything for the Magna Force Plus formula.


Arginine is the amino acid required for the production of Nitric Oxide.  Unfortunately, supplemental Arginine is not absorbed well because it is broken down by the Arginase enzyme.  The Magna Force Plus makers would probably tell you that it’s okay because Norvaline blocks Arginase, but that’s speculation, not fact.

There’s really no point in supplementing with Arginine because Citrulline raises plasma Arginine levels more effectively anyway.  Citrulline is what you want, not Arginine.  Magna Force Plus may contain Citrulline, but why contain Arginine at all.  It would be better to just throw in some more Citrulline and skip the Arginine all together.


Maca is distinct from the other ingredients in the Magna Force Plus formula in that it is not an amino acid.  It is an herbal extract that has been used for thousands of years in various systems of traditional medicine, mostly as an aphrodisiac, but also as a general wellbeing enhancer.

It has been shown to enhance exercise performance as well, but it has no influence on Testosterone and will not cause accelerated muscle growth.

Magna Force Plus Ingredient Takeaway

Magna Force Plus contains the usual blend of “performance enhancing” ingredients.  Some of them are effective (like Citrulline), some of them are ineffective (like Arginine), and some of them are speculative (like Norvaline), but overall, the formula is nothing impressive.  It’s essentially a glorified pre-workout supplement.

What To Expect With Magna Force Plus

If you’re looking for a muscle builder, keep looking.  Magna Force Plus may make your workouts a little better, helping you acheive an extra rep or two on your exercises and increasing your endurance, but it won’t pack on muscle.  There’s nothing hormonal about it so you won’t have increased Testosterone or anything.  Any ad that says differently is a lie.

Is Magna Force Plus Safe?

Magna Force Plus is definitely safe because all the ingredients are amino acids that you consume regularly in your diet anyway or that your body makes on it’s own.  The only herbal extract is Maca which has a pretty solid safety profile.  Nothing to worry about in this formula as far as safety goes.

The Bottom Line

Magna Force Plus is marketed as a muscle builder, but that’s a pretty misleading claim.  It may potentially improve your workouts which could, after a while, lead to more muscle, but there’s nothing in the formula that will actaully accelerate muscle growth.  If you’re looking for a muscle builder that actually works, check out our Best Muscle Builders List.  If you’re just looking for something to improve your workouts, check out our Best Pre-Workout Supplements List.  As for Magna Force Plus, we’ll pass. exists to educate the supplement community and seperate the science from the hype.
