Can Caleat KD And Collagell G Be Taken While On Chemotherapy?

I suffer from Non Hodgkins Limphoma (CLL/SLL) and currently under Chemotherapy (Mabtas + Bendamustine). I had pain in knee joints and left shoulder joint. I have been advised by my orthopedic doctor (prior to Chemotherapy) to take 1 tab Caleat-KD and 1 sachet of Collawell-G for 3 months. I am 68 years (male) and as a support my Cardiologist had advised 1 tab Echosprin 75mg and 1 tab Atorva20. The Oncologist has not objected to any of these drugs. Please advise about Caleat-KD and Collagell-G, if I should continue, does it have any interaction with the drugs I am taking what should be the proper timing. My orthopedic doctor is presently not available for advise. Hence the request.
