I've been buying colostrum from them for about 10 years. From what I've in the colostrum market, theirs is the only one that is organic, regeneratively farmed, pasture- and humanely-raised, without other nefarious ingredients. A doctor I was seeing recommended it for gut health and the brand she sold me was OK, but pricey, not organic and had some extra ingredients I wasn't interested in. Add that to very reasonable prices, fast and trackable shipping (free with purchases over $75 NZ - about $45 USD depending on the exchange rate) and KILLER customer service. They've always had a great selection of colostrum products, but have expanded into some other supplement areas. So far, I've only tried the plain powder, powder with manuka honey and the plain tablets. But I would recommend everything they sell. If you're in the market for superior products and customer service, give NutriNZ a try. read more
