Our Verdict
The reliable budget option. NOW Foods runs ISO-accredited in-house labs, the products are Non-GMO and kosher, and they disclose 25% IgG (lower than premium brands but actually disclosed, which is more than most). NOW has been around for decades with a consistent quality reputation. The 25% IgG content means you'd need a higher dose for clinical effect, but at $0.77/serving you can afford it.
