What is Doctor's Best L-Theanine with Suntheanine?
Doctor's Best L-Theanine with Suntheanine is a patented form of the amino acid L-theanine. L-theanine is an amino acid found in green tea that is responsible for the relaxation-inducing effect of tea consumption. L-Theanine with Suntheanine has been shown to promote an alert state of relaxation. This is characterized by an increase in alpha brain waves (signifying a relaxed, alert state) and a decrease in beta brain waves (signifying an awake, excited state of mind). L-Theanine with Suntheanine may improve sleep quality, enhance mental acuity and soothe away tension and nervousness.

Why should I take Doctor's Best L-Theanine with Suntheanine?
Doctor's Best L-Theanine with Suntheanine contains 100% Suntheanine and is best known for its unique ability to promote relaxation without causing drowsiness. L-theanine is one of green tea's natural health-promoting compounds. It is the ingredient that is responsible for both the taste and the relaxing effects of green tea. Research shows that supplemental L-theanine crosses the blood-brain barrier within 30 minutes of intake and thus is able to exert its effects directly on the brain.

A Diabetic Traveler's Best Friend at the Hot Springs!
Size: 13-14 Women/12-13 Men, Color: Black-w001
I'll be honest — I bought these almost last minute before heading out on vacation to the Hot Springs in Carson City, Nevada. As someone with diabetes, I have to be really careful about my feet, especially on rough or hot concrete surfaces. Pool decks and spa areas can be brutal, and I've had too many close calls just walking around barefoot. I grabbed these water shoes almost as an afterthought, and they ended up being one of the best decisions of the whole trip. From the moment I slipped them on, I could tell they were going to do the job. They fit true to size — no awkward sizing guesswork — and they hugged my feet snugly without feeling restrictive or causing any pressure points (a big deal for me). The sole gave me just enough protection from the concrete and wet surfaces around the springs, and I never once felt like I was going to slip. That peace of mind alone was worth every penny. They're lightweight enough that I barely noticed I had them on, and they dried quickly after getting splashed or submerged. No heavy, waterlogged feeling dragging me down. I wore them in and out of the water all day and my feet felt totally fine — no soreness, no irritation, nothing. For someone managing diabetes, that's honestly huge. I genuinely have zero complaints. These delivered exactly what they promised and then some. Whether you're headed to a hot spring, a beach, a pool, or just doing some light water yoga, these are a solid buy. Hope this helps!

Great water socks
Size: 8.5-9.5 Women/7.5-8.5 Men, Color: Shark Blue
Perfect! I’m autistic and this was the last piece of the puzzle for my sensory experience at the pool. They feel like wearing socks with hard soles on and are great for if you need to walk through gravel or anything. They don’t trap water much and the fabric is stretchy and comfortable. I liked the range of colors, I got the one with sharks. I wear a men’s size 8 shoe and I got the same size here, it was the correct size with a little extra room.

Colorful, comfortable, durable water shoes
Size: 8.5-9.5 Women/7.5-8.5 Men, Color: Shark Blue, Size: 8.5-9.5 Women/7.5-8.5 Men, Color: Shark Blue
I have ordered 5 pairs of these water shoes. The quality is amazing the bottom is durable, the stitching feels strong, they are comfortable, slip resistant, fit true to size and look awesome! We ordered the paisley, the blue geo, galaxy, lightning (lightning was sent back as we received the wrong size) and sharks. Only reason they are getting a 4 star instead of 5 is because I would much rather have the cushion inside sewn in instead of it being like an insert but that is what I find to be most common with these type of shoes.

Love these for beach foot protection!!
Size: 10-11 Women/9-10 Men, Color: Black-w001
These water shoes were perfect for our cruise to Grand Turk. The beach was a little rocky once in the water & the bottom of these shoes protected our feet and made it comfortable they dry quickly they are lightweight and easy to pack and carry in a beach bag. I bought two pair of the black one for me one for my husband, and he even wore them which was shocking into me and loved them.!!!! they don’t have walking support so they’re definitely something that you bring with you put on your feet before you enter like water where you can’t see the bottom or rocks/coral and they totally protect your foot on the bottom

I received someone else’s returned product
Size: 7-8 Women/6-7 Men, Color: Sunset
The inner product packaging was already cut open and not sealed, and there was debris inside the socks: clear indicators that the pair I received was someone else’s return. They also run big and are very wide in the toe area. My daughter’s pair also ran big, but at least hers were sealed. Overall quality is a bit flimsy, so we’ll see how long they last.
