What about making your own? I do.

Stability of drugs and supplements are usually defined by 3 things: temperature, exposure to light and moisture. I would keep it in a dark, cool place.

Exposure to light is often the worst offender.

That's a good point. I keep it on the door shelf of a fridge inside a garage. I wonder if that'll help it stay longer.

i think the short shelf life of liposomal products is due to the nature of what they are
typically its a suspension of microscopic particles of the intended ingredient surrounded by a layer of lipid or fat that encapsulates it an a kind of a tiny fatty bubble. this is supposed to increase the absorption into the body dramatically.

these bubbles are known to break down gradually over time - at which point the liposomal nature of the product is not any longer there - but the basis ingredient is still there - so will presumably still have some effect.

the bottle probably has storage instructions on it - which will typically be the best way to keep it.
cold temperatures ( but not freezing) and darkness - and as less exposure to air as possible ( eg opening the bottle) - will all help maintain it for as long as possible.

many things last longer than the expiration date if stored carefully - including medications - i saw a study for the MOD that showed that most antibiotics lasted many year and were still entirely safe and useable for military personnel after this time.
