"Resveratrol Reserve" - good?

Is this trans-Resveratrol product good? I ask because I found it while looking for 99% Trans-Resveratrol and I'm considering purchasing this one if you have a favorable opinion of it.

Nature's Answer, Resveratrol Reserve, Cellular Longevity Complex, 5 fl oz (150 ml)

It has 3 Ingredients:
Proprietary Resveratrol Blend (RestoreVetrol)
[Trans-Resveratrol 99% (Polygonum cuspidatum), Red Wine Extract, Extracts of: Noble Red and Carlos Variety Fresh Muscadine

Grape juice, Seed & Skin, Concord Red Grape Extract, (yielding 125 mg of trans-resveratrol)]. 1040 mg †
Proprietary ORAC Blend
(Pomegranate, Red Raspberry and Purple Corn Extract) 700 mg †

Quercetin 27 mg

Thanks for your feedback

Not a big fan of "proprietary blends".

I like the Resveratrol , not so much the ORAC blend or Quercetin
