Increased Deep Sleep

Verified Purchase

Rewarded Review

The very first night I took this, I couldn't even hear my husband's snoring. A miracle! After a month now, it still has the same effect on my sleep. I'm so thankful I found this. If you have trouble falling or staying asleep. Try this. It improved my quality of life

L-Serine powder - brain assist

Verified Purchase

Rewarded Review

I have been taking L-Serine ever since reading the story in Fortune Magazine on Paul Cox the Internationally known Botanist. After reading his article, I believe he at least has a solution for slowing the Alzheimer's disease, and possibly assisting in the deterring pre-Alzheimer's. Lake Avenue has a grainy consistence and a light sweetness to it. I take it orally and let it dissolve in my mouth just like any sub lingual application of CBD, or Vitiman B-12. So far I believe it is doing what Mr. Paul Cox said it may do. Good luck and stay consistant in taking it everyday for best results. Age 68

This product was a game changer for me!

Rewarded Review

I have inherited sensory neuropathy with progressive neuralgia and numbness. After two months on this product my symptoms have improved greatly and I can now walk longer distances than I could a year ago. My neuralgia and numbness in my hands has been reduced by ca 50% and I can touch my face with bare hands for the first time in 2 years (all touch to the skin on my hands and feet is usually very painful). I feel no cognitive changes but would recommend this product for neuropathy symptoms caused by diabetes or inherited neuropathy diseases like HSAN1A.

For ALS

Verified Purchase

Rewarded Review

My husband takes this, one scoopful twice a day, to slow down the progression of his ALS. It's too early to tell if it's helping, but with all the good reviews we've read about L-SERINE slowing it down, he is willing to try it out. It helps that it's not too sweet. It dissolves quickly and there's no grit. He mixes in water. We will definitely be reordering again and again.

Best nights sleep in 20 years, impressive product.

Verified Purchase

Rewarded Review

Excellent product, I have noted significant improvements in memory, mood, calmness, sense of smell, taste and hearing as well as vividness of color perception. Also I have slept the best in 20 years with a full 8 hours without waking as recorded by my smart watch. Also I see great improvements in skin texture and healing speed. Keep in mind that I take a combination of the about 20 supplements so I feel that L-serine is a important piece of that nutritional puzzle that has a great impact as it is the only addition that I have made in months, and using it for just one month I see the benefits mentioned above.
