Arginine and Health publication series

Arginine and Health is a series of popular scientific publications about the amino acid arginine and its effects on health. The publication series is based on original research as well as thousands of peer-reviewed scientific articles. The publications have been written so that the basic concepts are easy to understand and apply in daily life. In addition to theory, the authors have included a few real-life cases. In these cases, they give examples of the effects of arginine for different target groups. Also, in each publication, the authors discuss common misconceptions about arginine.

Over the course of this series, the reader gains a deeper understanding on how arginine supports a healthy metabolism using body’s natural mechanisms, and which metabolic factors are of key importance for a healthy, medication-free lifestyle. The series is suitable for anyone interested in their own or their loved ones’ health.

The leading scientist, Jyrki Penttinen, MD, has been doing research on arginine for over 25 years. In addition to scientific research publications, he has written several best-selling popular science books on arginine and its health benefits. The second author Hannele Penttinen, MA, brings a pedagogical and sociological perspective to the research, and has also co-authored several of the books on arginine.

The following publications are available in English in the Arginine and Health series at the moment:

  1. Arginine - The Basics (available also on Amazon Kindle  and Google Play)
  2. Arginine and Circulation  (available also on Amazon Kindle  and Google Play)
