Pros
- High-quality, clinically studied GABA form (PharmaGABA) for reliable nervous system support
- Added magnesium citrate improves bioavailability and digestive comfort
- Vegan and free from major allergens, suitable for diverse dietary needs
- Eco-friendly packaging with 100% post-consumer recycled resin bottle
- Trusted brand with decades of industry experience and positive reputation

The NOW Supplements PharmaGABA 100 mg with Magnesium Citrate is a targeted formulation for anyone seeking a natural way to manage daily stress and maintain mental focus. Unlike generic GABA supplements, this product uses a patented, clinically studied form known as PharmaGABA, which is structurally identical to the GABA produced naturally in the body. This makes it highly effective for promoting a calm yet alert state without causing drowsiness.
Each capsule delivers 100 mg of PharmaGABA paired with magnesium citrate. Magnesium plays a crucial role in nerve function and muscle relaxation, and its citrate form is known for better absorption. The combination works synergistically: GABA helps quiet neural overactivity, while magnesium supports the body's stress response system. Users typically report feeling more centered and less reactive to everyday triggers within 20 to 30 minutes of taking a capsule.
Design and build quality reflect NOW's decades of manufacturing experience. The capsules are vegan-friendly, with natural color variation that indicates minimal processing. The bottle is made from 100% post-consumer recycled resin, a nice touch for eco-conscious buyers. Each bottle contains 90 servings, providing a three-month supply at the recommended one-capsule-per-day dose.
Potential drawbacks are minor: some users might wish for a higher GABA dose or a standalone product without magnesium. Additionally, individuals with certain health conditions (e.g., kidney disease) should consult a doctor before adding magnesium supplements. The off-white color variation may also seem unusual, though it is completely normal.
Overall verdict: This is a well-researched, high-quality supplement that delivers on its promise of stress relief and mental clarity. The addition of magnesium citrate and the use of sustainable packaging make it a standout choice. Whether you are new to GABA supplements or looking for a reliable option, this product from NOW is a solid investment in your daily wellness routine.

Buying Guide
Potency and Dosage Options
GABA supplements come in a range of strengths, and your choice should match your sensitivity and needs. Thorne offers two doses: 100 mg and 250 mg per capsule, giving you flexibility to start low or go higher. NOW provides a 100 mg PharmaGABA with magnesium and a 500 mg GABA plus vitamin B-6. The 500 mg option is the most potent here, but higher doses may cause drowsiness for some. If you are new to GABA, starting with a lower dose like 100 mg is wise.

Purity and Sourcing: PharmaGABA vs Synthetic GABA
Not all GABA is created equal. PharmaGABA is a natural form produced via fermentation using beneficial bacteria, and clinical studies suggest it may be better absorbed than synthetic GABA. Both Thorne and NOW offer PharmaGABA in their respective products, while the standard NOW GABA 500 mg uses a synthetic form. If you prioritize a natural, fermented source, Thorne’s PharmaGABA line and NOW’s PharmaGABA with Magnesium are top picks.

Added Ingredients for Synergy
Some GABA supplements include complementary nutrients to enhance calmness. The NOW PharmaGABA 100 mg pairs GABA with magnesium citrate, a mineral known to support relaxation and muscle function. The NOW GABA 500 mg adds vitamin B-6, which helps with neurotransmitter synthesis. Thorne’s products are straight GABA without extras. If you want a multi-nutrient approach, the NOW options offer added value. For men over 50 looking for comprehensive stress support, our stress support for men over 50 guide may be helpful.
