Is it safe to take a supplement containing Resveratrol for patients with multiple medical conditions?

Hello doctor,

My mother is 66 years old and has cholesterol but is under control with Fibator (Atorvastatin 10 mg and Fenofibrate 145 mg).

For hypertension, she is taking Seloken XL 50 mg in the morning and Amlogard 5 mg in the night, and with this medication hypertension is under control. She is taking Lyrica 75 mg two in the night and Tegrital CR 400 mg at night for trigeminal neuralgia. With this medication no stabbing pain on the forehead for the past year. She is taking Tropan 5 mg thrice and Cranpac twice for uncontrolled urine caused by recurrent urinary infections. But with this medication, there has been no urinary infection for the past 8 months. She is having knee pain and reduced mobility and her bone mineral density test revealed osteopenia. She was prescribed Freeflex Forte thrice, and Miacalcic nasal spray once in the morning. Relief for her knee pain is reasonably good. She is a pure vegetarian. She has undergone uterus and ovary removal 15 years back. She does walk in the morning slowly. She is non-diabetic.

Now for her wellbeing can she take a new antioxidant with plant extracts, which contains Resveratrol 5 mg? Is this plant extract safe for her, if so what dosage and duration?

Please advise. Thank you.
