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

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.

Relatively good buy for Amazon. Recommend Subscribe & Save for at least a 3-month period (IMO).
Good product, however, not really sure if it is doing anything. It's not one of those products where something happens right away, at least in my experience. This product, overall, is relatively high priced in the supplement area. It cold be one to try for a 3-month period with probiotics to find out if someone feels better in different ways, as in elimination, gas, bloating, etc. I like to try trendy products backed by science, like this version, to see if it helps with overall health. There are other brands with larger containers, although this one was a relatively good buy for the price per ounce. It averages 30 servings, so a good trial, IMO, would be a repeat purchase. One may try the Subscribe & Save, to save more, about $0.10 per ounce, and cancel after the 3 months if nothing has improved.

It works for me since I started using this product
I really love this product because I helped with my hot flash at night. I commanded this product to anyone having hot flashes at night

Kept me awake
I’m sure this might work for others but it kept me awake for some reason. I was using it to combine with melatonin for better sleep (chronic insomniac here) but had more luck with the chelated magnesium glycine lysinate version. Weirdly, less melatonin worked better than more. I suppose I could try taking it earlier in the day and see if it’s more of a delayed effect.

Great for sleep and relaxation
I've been using Doctor's Best L-Theanine with AlphaWave for a few weeks now, and it's made a noticeable difference in my sleep and relaxation. I take it along with magnesium, and the combination helps me fall asleep more easily and stay asleep through the night. L-Theanine is known for promoting a calm, relaxed state without drowsiness, and AlphaWave is a high-purity form that’s supposed to enhance those effects. I haven’t experienced any negative side effects, which is important to me. Plus, I appreciate that it’s non-GMO, gluten-free, soy-free, and vegan. If you're looking for a natural supplement to support relaxation and better sleep, I’d definitely recommend giving this a try.

So far so good
Using with hydrogen dominant Sibo and numerous additional food allergies. I put this in my beef protein chocolate shake and so far so good!
