L-Theanine works with key neurotransmitters in the brain, including GABA, dopamine, and serotonin. This supports a state of calm focus that allows you to stay sharp and composed without feeling slowed down or wired.

Unlike stimulants or sedatives, L-Theanine supports mental performance through balance, not force.

• DUAL ENERGY SOURCE – NutraBio’s CaffPlus combines the power of fast acting PurCaf Caffeine with the sustained released of Infinergy Caffeine. This ensures smooth long lasting energy, without the crash.
• ORGANIC CAFFEINE – NutraBio CaffPlus features PurCaf’s Organic Caffeine, extracted from green coffee bean.
• ENHANCED COGNITIVE FUNCTION – This formula is balanced out with 200mg of TheaPure L-Theanine, which reduces jitters while enhancing both cognition and focus.
• SUPERIOR QUALITY - NutraBio uses only the best, and this product is no exception. CaffPlus is non-GMO, gluten free, soy free, vegetarian, third-party tested, and made in the USA. We also use an excipient free encapsulation process.
• THIRD PARTY TESTED, FULL DISCLOSURE – Like all NutraBio products, CaffPlus is tested by an independent third party lab to ensure it is both pure and meets our strict quality standards. All NutraBio products feature fully transparent labels with no proprietary blends.
