Doug Jaser became interested in Nutrition when he witnessed his father become ill and pass away too early in life. This experience revealed to him that health is paramount because whatever else you have in life is limited or enhanced by the degree that you possess health.

He began Health and Lifestyle Coaching in 2011 and moved from Connecticut to Walnut Creek in 2014. Before joining ClubSport, Doug worked at Pharmaca Integrative Pharmacy helping customers make the best nutrition and lifestyle choices.

He believes that people should start dietary changes from where they are and integrate new foods and habits mindfully so that they develop an awareness of what works for them and why. He looks forward to assisting you with your health and wellness goals.


Nutrition Supplements

Supplements will never replace proper nutrition, but they can help you hit your fitness goals faster! Supplements complement your diet and help cover nutrient gaps, ensuring that your body has what it needs for peak performance. No matter what your training goals are, the right supplements can help improve your health, performance, and physique.

The supplements we carry are categorized to make it easy to navigate through the supplements available that will directly impact your symptoms to optimize your health.
