Rosemary Barclay, PhD, CNS, Nutritionist/Dietitian in Old Lyme
Rosemary is PhD biochemist, a board certified nutrition specialist and esthetician. Her vast experience in pharmaceutical clinical research allows her to conduct in-depth research on individual cases and make factual recommendations. She educates her clients to learn fact and dispel myth. She promotes healthy eating and not FAD diets. Her skills include weight-loss, therapeutic nutrition for lowering cholesterol and high blood pressure, developmental and sports nutrition, nutrient depletion, drug/herb interactions, dietary supplements and nutritional guidance for diabetics. In addition, she runs a successful natural acne clinic using nutritional guidance, supplementation and healing skincare.
Educating clients to take control of their weight and lifestyle is key. There are a lot of myths about diet and nutrition-my counseling is based on fact and not myth. We encourage clients to eat nutrient dense whole foods and not rely on shakes or protein bars..
I treat each case individually and work to achieve results. My experience in pharmaceutical drug development and board certification in nutrition make me knowledgeable and unique
