Hello, Thank you for asking your query at DoctorSpring.
Its great that you have taken the step to reduce your weight, going to gym and working out the fat is a good start. As you are hypertensive, its important you maintain a good and healthy weight.
In my opinion, there is no need to take supplements like maximuscle lean to lose your weight. Simvastatin does have lower efficacy when taken with calcium or vitamins. You don't want anything effecting your drugs efficacy rite. These supplements are usually taken by athletes, for good performance. It would be better if you avoid these supplements, rather go for natural supplements. You can take proteins like nuts and driedfruits, fibre like fruits and vegetables, meat like skinned out chicken, egg are all natural supplements if taken whwn you are exercising will reduce your weight.
As you are hypertensive I also suggest you to go for, meditation or yoga. Its evidence proof that they help you to maintain your blood pressur and relieve your body of toxins and reduce weight in a healthy way.
Hope this helps.Please feel free to ask follow-up questions
