Turmeric & capcacin questions

Does anybody truly know and has found some sort of proof of the effectiveness of turmeric and capsaicin on weight loss? And if not weight loss then Brown fat Cell Activation, muscle growth, metabolic speed and health, appetite, or just general provable Health benefits? For context, I've been working out and doing everything that I can to take a more healthy approach in life, and I currently take turmeric pills, capsaicin supplements, fish oil, and the v-shred burn capsules, but I want to know if I'm just wasting my time and this isn't helping me in the slightest. I have a feeling the v-shred is unneeded but does capsaicin and turmeric actually help your body in these processes, because Google keeps telling me that it's all theoretical and the like, and I know I can't just open my body up to say oh hey look it's working, but is there anybody with some sort of proof? I understand that these are not some miracle pillows and all of them need a calorie deficit at the least and a workout routine to be truly effective. But I'd like to know
