“Very professional consultation!! I’ve realized how important it is what we eat and when we eat. I had health problems and especially hormonal imbalances.. Thanks to Ola I did not have to take hormonal drugs. It was enough to adapt to the recommendations which was not difficult at all!! I am healthier and I have a lot of energy!!! Consultations with Ola it was a pleasure and she was always available when I needed her support !!! I am extremely grateful !!!!Highly recommended!!!”

Very professional

“Consultations were carried out in a very relaxed atmosphere. I thought that I knew a lot about healthy lifestyle but I was making mistakes which Ola made me realise. Introducing her advice to my diet was for me a very pleasant and tasty experience. I’ve changed my eating habits and feel great! Moreover I have lost 8.5 kg and this is only the beginning. I think Ola is very professional at what she does, also she treats everyone individually. I would happily recommend working with her”

Very relaxed atmosphere

“I came to Ola after my friend recommended her to me. Ola is delightfully person with a large knowledge of nutrition and a positive attitude to life. Consultations with Ola gave me a lot of new information I had no idea of and that changed my view on health. Consultations with her are very pleasant and always interesting. Ola is patient, friendly and leads me by the hand to achieve a healthy lifestyle. Thank you Ola, for your support and your professionalism. I would recommend to anyone who wants to live a healthy lifestyle. Ola, I wish you much success.”

Consultations with Ola gave me a lot of new information

“I reached to Ola when my immune system was at my lowest. I’ve been on 5 antibiotics within previous 10 months due to continuous infections. I knew a bit about healthy eating, read few books myself, but couldn’t put all the pieces together. Ola was the person who helped me do that. She investigated all of my symptoms, looked at my lifestyle, medical history and came up with a plan. Plan, that helped me to make really positive changes in my life. Her review was very thorough and just spot on. She gave me lots of advice which foods to eat and which products to avoid, explaining why, which I found very helpful. I followed the plan from day one and could see change in how I felt just after a few days. A real difference it made a month later, when I got another infection and was able to fight it myself, without a need for medication. I’d recommend Ola to any person seeking nutritionist’s advice. She’s very enthusiastic in what she does and her attitude is very professional. She treats clients problems in a very individual way and looks at tailor made solutions that would work in individual circumstances.”


“I’m really happy with changes that Ola suggested to me on our consultations. The tips and information that I was given were very helpful. Some of them were new to me. I would recommend Ola to anyone who is experiencing health issues relating to unhealthy lifestyle. Big A+ for Ola for her approach to client. She has got big knowledge of nutrition and healthy diet.”
