Dr. Finnegan recommends supplements from high quality and reputable manufacturers that can only be purchased with a practitioner’s recommendation. The wellness plan that Dr. Finnegan creates has specific dosages based on the exact ingredients in that specific supplement. If you want to do your own research on different supplements, we welcome you to do so but we do not provide any other recommendations nor advise on other specific blends or brands. If you purchase other supplements from other manufacturers, please research carefully. Not all ingredients are equal, and there is not a guaranteed quality when you purchase supplements elsewhere, especially on Amazon, where there are often fraudulent products for sale.
