Using a CBD Hemp oil with good bioavailability is very important. Buying a cheap, poorly made product will mean you need to take much more of it to have the effect you desire. Prime Spectrum CBD products have, by far, the best bioavailability in Ireland. This means you need to take less of our products to have the desired effect you require. This means the product could last you twice as long as other brands. Product selection and dosage are the other two most important factors and we are with you every step of the way to help you here too.
