Hemp and CBD Products

Rhizo Sciences is a leading supplier and distributor of wholesale hemp and CBD products internationally. We are committed to building industry standards, infrastructure and supply chains to establish global legal accessability for CBD derived ingredients and medicines

Wholesale Hemp and CBD Procurement and Manufacturing

We deal exclusively with bulk enquiries from 10kg of concentrates or 450 kg (1000lb) of flower products, and only operate within compliant legal markets with qualified suppliers and buyers. We specialise in helping manufacturers and brands to procure suitable hemp derived CBD or to develop their own supply chain to ensure continuity of supply.

Food Grade and Pharma Grade GMP CBD

As large players like Coca Cola enter the CBD industry the pressure is on processors and manufacturers to meet international standards for food standards such as HACCP and pharmaceutical standards such as cGMP (current Good Manufacturing Practice). Rhizo Sciences works with our farms and processors to help them attain FDA and other certifications needed to meet quality expectations of pharmaceutical, nutraceutical, food and beverage manufacturers. Due to the newness of the industry, supplies of GMP CBD are strictly limited and there is a significant price premium for product manufactured under compliant conditions vs the garage lab product currently flooding the market.

Pharma Grade CBD Products

Our GMP Manufacturing Facilities allow the production of pharma grade CBD products suitable for compliant pharmacy distribution, including APIs (Active Pharmaceutical Ingredients) such as purified cannabinoids and terpenes.

Note that GMP grade products may be GMP compliant, not certified in some locations including the United States.

CBD Isolate

CBD or Cannabidiol is an important non-intoxicating cannabinoid derived from hemp or cannabis. Renowned for it’s anti-inflammatory and other therapeutic effects, CBD has been declared as broadly safe with recognised medical uses by the WHO (World Health Organisation).

CBD isolate is purified cannabidiol. CBD Isolate appears as a white powder comprising small crystals. Impurities may result in an off-white, yellow or pink tinge.

CBD isolate is typically sourced from medical hemp or industrial hemp.

Note that while CBD isolate is the purest form of CBD product, it isn’t always the best – there are many valuable therapeutic effects from the other cannabinoids, terpenes and other compounds found in hemp flower and biomass, hemp-derived CBD oil and CBD distillate, which have been removed while purifying CBD.

CBD isolate is popular for nutraceutical and pharmaceutical use, and is increasingly finding it’s way into vape products, topical products and even animal products.
