Kavinace is great!

A friend recommended Kavinace. I tried it and haven't had any more problems with acid reflux from the melatonin I had been taking and the Kavinace works just as well as any Melatonin.

Good night sleep

This works great and let me have a solid good nights sleep

Natural Healthy Concepts is the Best

I would recommend this product to anybody that needs help with occasional stress management. It works wonders on the central nervous system and is a great way to support stress.


Finally received Kavinace and am very pleased with the results.

Finally sleeping

It does help me get a good night sleep & there is no "hangover" in the morning.l

Didn't work for me

I am sorry to say it did not work for me. I understand that it is one of the best selling sleep aids. I am finding out that what works for others does not always mean it will work for you.


I love this product. It really works.


Kavinace helps with anxiety and calms me.

Helps to relax

Wonderful aid to a good nights sleep with no hangover or sluggish feeling the next day.

Helps me get sleepy

I've found that taking three capsules of Kavinace along with dual-action melatonin and Taurine with B6 works for me. I've had to modulate my dose of Kavinace from four to three capsules a night, because four left me groggy in the morning. Thank you, Kavinace!


Kavinace Great seller and product.

Kavinace is great

Kavinace has been a relief for me.

Kavinace and Natural Healthy Concepts are a True FIND!

A friend recommended Kavinace to me a few years ago. I like that it is an herbal. Natural Healthy Concepts is my first choice whenever I look to purchase vitamins or supplements, and, their customer service is first rate!

Great Product

Kavinace is a great product.


My doctor suggested Kavinace and it works!


Kavinace is a miracle pill. I use it for a peaceful day. It works great! Highly recommend!

Kavinace helped

Kavinace really made a big difference for me. I woke up feeling more refreshed, no hangover feeling some products can give you. I recommended it to several of my friends and 2 out of 3 felt a significant difference.


Kavinace has helped and gives me hope.


Works Great

Good service

the items always arrive in a timely manner. It is good value also

Great Business

I order 1 product every month from Natural Healthy Concepts and I find them to be very easy to order from, consistently prompt on delivery, and reliable. I would recommend them as a source of supplements.


I have been using Kavinace for several year. My daughters nutritionist recommended it. It has definitely helped me and I will continue to take it.


Kavinace is more helpful for sleep and relaxation that any non-medication I have found. It only takes about 45 minutes to kick in.

Great natural sleep support

I tried it and loved it and have continued to use it for about a year now. Highly recommend it.


Kavinace has been a tremendous help to me.
