Service Rating: Prompt delivery as always. I’m very pleased to see 400mg L Theanine back in stock. I had to buy from a different company last time as only 200mg were available. I don’t want to have to take two capsules when I can take one so it’s good to be back with Just Vitamins!
Product: Just Vitamins products always arrive quickly. Their use of sealed bags instead of plastic tubs means multiple orders can be delivered in an A4 padded envelope together. Also the packaging does not cantain plastic. Great service.

Service Rating: Speedy delivery thank you and encapsulated product
Product: Still a lot of fillers and binders in this encapsulated product and they could not explain the addition of another additive. I find griffonia seed effective at helping me remain asleep to prevent 1.5 hourly awaking.
