Nutritional Advisory Board

Why do we have a Nutritional Advisory Board?

When developing OASE Hair Vitamins, our mission was to create delicious natural blackcurrant flavored Soft Gums that could be enjoyed universally, but we couldn’t do it alone. We scouted for the top experts of the wellness and nutrition field and created this Nutritional Advisory Board (NAB): a team of the brightest minds in the food and gummy industry.

These hand-selected leaders that make up the OASE Nutritional Advisory Board have extensive expertise in a range of fields from ingredients, to health, hair, gummy production, nutrition, and much more. They have served as a guiding star, sharing with us their knowledge and latest information, so that we could develop the world's best Hair Vitamin Gummy.

With their help and expertise, we have created the OASE Soft Gums, a patented formula that makes them delicious without sacrificing the integrity of its benefits.
