Abstract: Vitamin B12 is a critical nutrient that is often inadequate in a plant-based (vegan) diet, thus the inclusion of a reliable vitamin B12 source in a vegan diet is recommended as essential. Unfortunately, many natural sources of vitamin B12 have been proven to contain biologically inactive vitamin B12 analogues, inadequate for human supplementation. The aim of this non-randomized open trial was to determine whether supplementation with a natural Klamath algae-based product ("AFA-B12", Aphanizomenon flos-aquae algae plus a proprietary mix of enzymes) could favorably affect the vitamin B12 status of a group of 15 vegan subjects. By assessing blood concentration of vitamin B12, folate, and more importantly homocysteine (Hcy, a reliable marker in vegans of their B12 absorption), the vitamin B12 status of the participants at the end of the 3-month intervention period, while receiving the Klamath-algae supplement (T2), was compared with their vitamin B12 status at the end of the 3-month control period (T1), when they were not receiving any supplement, having stopped taking their usual vitamin B12 supplement at the beginning of the study (T0). Compared to the control period, in the intervention period participants improved their vitamin B12 status, significantly reducing Hcy blood concentration (p=0.003). In conclusion, the Klamath algae product AFA-B12 appears to be, in a preliminary study, an adequate and reliable source of vitamin B12 in humans.

TESTIMONIES

"We are so excited about the Bluegree Body Algae. We´ve seen some real benefits for the immune systems of animals. We had a 12 year old dog brought into the clinic who had been hit by a car. We decided to start him eating Bluegreen Body and the Enzymes. The dog had to be in a splint for 3 weeks. Every week when he came in to be checked he was looking better and better. His condition and haircut were improving. By the third week his owner was so impressed she started using the same supplements. The dog´s attitude is wonderful. The day he was brought in he bit one of the techs and he didn´t want anyone to do anything to him. After a couple of days, even though he was still very sore, there was a major improvement in his behavior. Now when he comes in he even kisses everyone. We also do short nail clips for show dogs. I decided to try sprinkling algae on nails that we quickened to see its effect. It did a wonderful job - so we have switched!"
