Yep they go slimy. I have a litre bottle I put 1 tablespoon of chia seeds in so there is not enough to turn it to jelly.
You can make it jelly like with less water and use as an egg substitute in recipes.
I suffer from Fibromyalgia...this was something I tried out of desperation...not a cure but it has helped me. I also use macca root powder in smoothies. Almost forgot to say I add Gus' Phyt'n chance in smoothies.
