People use flaxseed oil for a number of reasons and they also provide a range of health benefits. In this article though we answer the question do flaxseed oil capsules go bad? We have done a full article on why people decide to use capsules rather than the oil itself. It also includes how many capsules a day you should take. You can read that by clicking here.
Typical Flax Seed Oil Capsule Ingredients
To determine if something is going to go off or start to turn rancid, always have a look at the ingredients. I took a snapshot of a typical jar of capsules so as you can have a closer look at what these actually contain. You can see these from the image below:
From this it can be determined that the only elements that will deteriorate over time is the oils and in this case it will be either the flaxseed oil or the linseed oil. A typical jar of capsules will normally contain about 90, 180 or 360 capsules and if taken at one a day, they will last for 3 months, 6 months or a year.
Many manufacturers recommend taking two capsules a day so if you go with their recommendation then these will last for about half the time shown above. What you can deduct from this is that the first thing you need to decide on is the actual dose you will be taken, either 1 or 2 capsules per day.
So if you bought a jar of 180 capsules and took 2 a day then they would last you three months.
The jars are sealed when bought so no air can get at them. Most of them will also have a date when they should be used before so always check this on the tub or jar itself. When opened then air and moisture can get at the capsules and therefore at the oils. They are however protected by a typical gel like skin so the air can not get directly at the oils inside.
Do Flaxseed Oil Capsules Need to be Refrigerated?
Almost all manufacturers use airtight bottles to store their tablets. You do not need to keep them in the fridge but you should keep them out of direct sunlight. Now many people prefer to keep them in the fridge but it is not an absolute requirement.
The oils inside are protected by a gelatin style cover as you can see on the image to the left. In this case they have used a caramel colour but these colours do vary between manufacturers.
Flaxseed oil should however be kept refrigerated but there is no requirement to do the same with capsules.
I think the big difference between the oil and then taking it in capsule or gel form is that with the oil, it does not come in airtight bottles and it has no outer protection. That is why the manufacturers of that recommend storing it out of daylight and if kept in a fridge will certainly last longer.
With capsules that is not an issue. There is also nothing wrong with keeping them in the fridge if you prefer to do that.
How to Store Flaxseed Oil Capsules?
The first thing that I do is to check the date on the bottle or jar. So if I plan on buying 180 gel capsules and I take one a day I know the date needs to be at least 6 months away. I do store my capsules in the fridge but that is simply because I remember to take them when I use the milk in the morning time.
I would recommend though keeping them out of direct sunlight as that can impact on most medicines and reduce their lifetime.
