Further Food Collagen Peptides review

Further Food makes a plain collagen with clear answers on testing. The FAQ says the powder is 100% hydrolyzed collagen peptides, Types I and III, with no sugar, preservatives or sweeteners, and that it is certified kosher by Kosher Supervisory Services. The company says the peptides undergo heavy metal testing and are made in cGMP certified facilities, and it says the product contains 18 amino acids, 8 of them essential. Sizes are a 10 oz tub with 14 servings, a 21 oz tub with 30 servings and 12-count stick packets, and the page notes a 30-day money back guarantee and HSA/FSA eligibility. The store showed us a converted price, so we could not confirm the US list price as of November 13, 2026 and marked it pending; check the price on the vendor page before buying. Without a confirmed price and with no NSF mark, it sits below the leaders, but it is a sound pick for kosher households.
