It is probably still good. Those dates are not always reflective
of spoilage.
Oils...they are the most likely to go bad. Aspirin products, too.
Vit C will oxidize with time. Antioxidants will eventually pick up oxygen and show it somehow.
The old R-form would polymerize and form a sticky non-absorbable chain. This new one is even more heat stable
than the old one. Moisture could be a problem and that would leave visible signs. I put extra moisture preserving packs in all my supplements. I don't throw them away unless they are "old".
You can recharge them with a hair dryer on low heat
If the capsules are not discolored or clumped inside the bottle is probably still good.
