Very effective!

I ordered this for my teen daughter who feels she has attention and focus issues. From day 1 of taking this she felt it really helps! Our family takes several supplements from this company and have found them all to be very effective.

OMG!

Many family members have had dementia. When my mother was in a memory care the stress rocked me and my memory began to waddle. From the stress also working as a teacher I developed a voice issue that is supposedly in the brain. I saw that lions mane was excellent for cognitive and memory. I began taking host defense lions mane and made a significant difference. Still having the voice issue I was able to move forward and back into life. I switch to Brainstack and even better results! Host defense excellent quality and ingredients pure.

enhances focus and mental clarity

The first time I tried this I instantly noticed it improves focus and that was unexpected as I was taking it solely for long term brain health with no acute benefits expected.

Tastes like biscuits, feels steadily refreshing.

I take the dosage of 1/8 a teaspoon with my morning drink, and the size of the pot means the powder lasts about 4 months. The product's quality gives me the benefit of becoming calmer; even though I tend to be busy. Tastes negligible really, no strong or overly sweet flavors, mildly tastes like bread or biscuit.

I took before only mushroom lion's mane from this brand, it was ok, but this time with b12, I should have more energy with this amount of b12 but i didnt. also I got skin irritation, so I reduce the dose. also it doesnt come with scope. The taste is strange, but cant drink it with water, so better mix it in glass of water or take it with yogurt.
