Glycine is an amino acid that supports the central nervous system and sleep quality. It is considered a conditionally essential amino acid–this means our bodies produce glycine, but often not enough to meet our needs. Glycine is an important precursor for many critical molecules, including glutathione, the body’s master antioxidant. Glycine can help support:
- Improved sleep quality and duration*
- Healthy neurological function*
- Healthy aging and glutathione production*
Clinical studies involving glycine supplementation have reported improvements in sleep quality and feelings of next day energy and mental clarity.*
Supports neurological health. Age-related declines in memory and learning have been associated with changes in the NMDA receptor system. NMDA receptors are a group of ion channels that support memory and synaptic plasticity. Glycine may help support biochemical pathways related to the NMDA receptor system.*
Supports healthy aging and glutathione production. Increased oxidative stress is a hallmark of aging. As we age, glutathione (our body’s master antioxidant) decreases over time. Glycine, as a building block of glutathione, can help optimize glutathione production. A clinical study involving supplementation with glycine and N-acetyl cysteine (another glutathione precursor) observed improvements in glutathione levels and several aging hallmarks.*
Preclinical evidence suggests that glycine may also act as an autophagy activator and help clear methionine from the body, two important roles in supporting longevity.*

Lovely sandals!
I highly recommend!
These are so comfortable! Right out of the box, they can be worn all day. The velcro-adjustable straps are great for making for a perfect fit. The aren't clunky to wear, even though they appear to be. They're super cute, in my opinion. The sock liner is textile, so feet feel good all day, not slimy, like leather and suede can sometimes make feet feel if socks aren't worn.

Cute and Comfortable
Size: 10, Color: Black
This is my second pair. I bought the sand color at my local Macy's. I got their last pair. I have issues with back pain and ankle swelling and pain. These are so comfortable I had to get them in Black. The adjustable straps are great. My feet are a little bit wider because of the swelling issues. So if you have very narrow feet these might be a little big. You might want to go down a half a size. But otherwise I wear a size 10 and they fit perfectly. I don't think the picture does the color justice. The black almost looks like velvet, it's very deep and rich. I wore them out today for the first time and got lots of compliments. The footbed is very comfortable with the memory foam. Lots of support. I noticed my back and ankle pain is much better wearing these. I've never owned UGG before. If these hold up really well and continue to stay comfortable, I will be purchasing other styles for fall and winter.

My new favorite summer sandal!
Size: 8.5, Color: Bay Fog
I am loving these shoes so far this summer! The color is so cute, perfect for a light summer palette. It's the perfect light purple that doesn't make me look pale or washed out. For reference, I have fair to light neutral skin tone. They are SO comfortable - a little too comfortable for a shoe, it's more comfortable than my ugg slippers! They do take a second to put on as you have to either force your ankle in without unstrapping the back - don't judge me - or undo them. Thankfully they have a strap to help get them on easily. I love these shoes. I am a medium width, but I think these have some wiggle room since both the straps are velcro and adjustable somewhat. They are easy to walk in, hold onto the foot, have been more balanced than some others I have had in this platform style, and are very cushioned to walk in. Slight arch support to me but I have somewhat high arches so if you are more flat footed or standard arch these will give you even better support. Really impressed with these. They are more casual but work with many different outfits from sundresses to jeans. For me, these were a great buy and I will be wearing them all summer.
