Overview

The NOW B-Complex provides a comprehensive blend of B vitamins, choline, and inositol, formulated at high doses to support energy production and nervous system health. While the formula contains many beneficial B vitamins, PABA and Inositol are included at doses that lack supporting clinical evidence and may not deliver significant benefits.

The Good

Provides a high dose of all essential B-vitamins.

May help correct B-vitamin deficiencies.

Supports nervous system and energy production.

The Bad

Excessive doses of B vitamins can cause side effects such as digestive upset and nerve issues.

The inclusion of Para-Aminobenzoic Acid (PABA) and Inositol at 50mg each provides minimal benefits and has limited supporting evidence.

High doses of some B vitamins like niacin can cause skin flushing.

Is it for you?

Best For: Individuals seeking energy support, those with B-vitamin deficiencies, people looking to support nervous system health

Skip If: You are sensitive to niacin or experience significant gastrointestinal discomfort; consult a doctor if pregnant or nursing.
