OVERALL EFFECTIVENESS 88%

SPEED OF RESULTS 87%

PRODUCT SAFETY & QUALITY 88%

LONG TERM RESULTS 88%

CUSTOMER SATISFACTION 87%

Money Back Guarantee: 90 Days

L-arginine X is a formula almost identical to Arginine Infusion with a combination L-arginine and L-citrulline along with CoQ10 and minus the AstraGin.

One big difference seemingly holding L-arginine X from really standing out is the fact that it’s a little more difficult to mix than our highest rated L-arginine supplements. You also might get a slightly bitter flavor with L-arginine X, but overall still comes in as one of the top L-arginine supplements.

#5 - ProArgi9

OVERALL EFFECTIVENESS 85%

SPEED OF RESULTS 86%

PRODUCT SAFETY & QUALITY 85%

LONG TERM RESULTS 84%

CUSTOMER SATISFACTION 85%

Money Back Guarantee: 90 Days

When it comes to Proargi9+, some are turned off by the fact that it’s only available through the multi-level marketing option through Synergy Worldwide. As part of Synergy, as with most multi-level marketing companies, you’ll be paying more. When it comes to reviews, Proargi9+ reviews remain mixed.

You’ll get a proprietary combination of L-arginine, xylitol, pomegranate fruit concentrate, l-citrulline, d-ribose, grape skin extract and red wine extract along with a mix of vitamins and minerals. You do get a few flavor options and Proargi9+ also comes in stick packs for a more convenient option. But at $70 a bottle, you get less overall value than with other L-arginine supplements you can buy directly.

#6 - Niteworks

OVERALL EFFECTIVENESS 84%

SPEED OF RESULTS 85%

PRODUCT SAFETY & QUALITY 84%

LONG TERM RESULTS 84%

CUSTOMER SATISFACTION 84%

Money Back Guarantee: 90 Days

Like Proargi9+, Niteworks is a product available through a multi-level marketing company, Herbalife. And with less L-arginine and L-citrulline than higher-rated products, you’ll still be paying more than $80 a bottle.

As the only lemon-flavored L-arginine supplement on our list, Niteworks is unique and some people love the flavor but don’t expect results to come as quickly unless you decide to take a little more each day.

#7 - Forever Argi+

OVERALL EFFECTIVENESS 82%

SPEED OF RESULTS 82%

PRODUCT SAFETY & QUALITY 82%

LONG TERM RESULTS 84%

CUSTOMER SATISFACTION 81%

Money Back Guarantee: 90 Days

Forever Argi+ provides users a combination of L-arginine with beneficial vitamins and minerals. At more than $60 a bottle, it’s not the most affordable option when it comes to taking L-arginine.

While the price is high, the flavor is one of the best you’ll find and the powder mixes easily even in cold water. However, Forever Argi+ lacks one key ingredient, L-citrulline so you’re not getting as much out of it as you would get from some other products.

#8 - X-Cell

OVERALL EFFECTIVENESS 81%

SPEED OF RESULTS 81%

PRODUCT SAFETY & QUALITY 81%

LONG TERM RESULTS 81%

CUSTOMER SATISFACTION 80%

Money Back Guarantee: 90 Days

X-Cell from LifePlus is another product tied to a multi-level marketing company. This arginine-based formula comes in with 2,660 mg of L-arginine in each serving combined with 700 mg of L-citrulline.

This simple formula is much less popular with about half the L-arginine you’ll get with higher rated L-arginine supplements. While it’s great to see it also includes L-citrulline, the flavor is a little lacking and makes it more difficult to take.

SPEED OF RESULTS 76%

PRODUCT SAFETY & QUALITY 77%

LONG TERM RESULTS 77%

CUSTOMER SATISFACTION 78%

Money Back Guarantee: 90 Days

If you’re looking for a simple L-arginine supplement, NOW Foods L-arginine Powder offers a L-arginine powder in both capsules and tablets.

While every other product on our list is a combination of L-arginine along with other ingredients, NOW Foods L-arginine powder is L-arginine alone and you can get it in various amounts. While the cost of $10 to $12 is appealing, remember you’re getting a fraction of L-arginine that you’re getting in the other recommend L-arginine supplements.
