UK aloe source?

I've been struggling to find a decent source of aloe powder in the UK, but have found three freeze dried inner leaf brands - In particular I think the brand Tiny Pioneer might have what we need.

Aloe 72Omg (freeze dried, inner leaf), two capsules would give 1440mg. I think it's close enough to 1500mg to give it a go. Bottle of 150 capsules is about £59, but would last 2.5 months at the above dose. Much cheaper than powders I've found.

Next is global healing 180mg, but this would last a week only for £35 at 60 in the bottle and 8/9 capsules a day so very expensive

Desert harvest 600mg £65 uses the whole leaf but removes the laxative so it can be used daily. A bottle would last 2 months if 3 taken a day (1800mg). Could try splitting the capsule to get 1500mg exact and make it stretch a couple extra weeks.

Please let me know if you have found any others worth a look!
