Review: Menopause it's - This is a great product for women that is going through menopause. It works really good if you need relief for at night. This works good from the night swept and hot then cold this product works
Review: Tastes like mochi to me - It tastes like mochi to me and I like taking it in water as it tastes good. Mixes fairly well. I give it a good stir and let it sit for a little bit so it dissolves more, but I will just eat the clumps if there are some still. If you like mochi, you should like it. I'm trying it because I am having problems with bloating reacting to fiber because of digestive issues. I can't say whether it's good for my usage yet, but I don't think it's causing me to bloat.
