## Questions & Answers

**Q: Does anyone make this formula gluten-free?**
A: This product is gluten-free.

**Q: Whats the difference between these and the l theanine serene with relora?**
A: I used this product with great results for several years and then tried the version with Relora.   I accidentally and unbeknownst to me, reordered but received the version without Relora.   I kept getting the urge to nibble and snack in the evening, and that's when I discovered my refill didn't contain Relora which is known for reducing the urge to snack.   Well,  I  discovered that in fact it does and in spite of the fact that I take 2 in the late morning and it's eliminated  the urge to snack in the evening.   I never noticed any dozyness or sleepy daytime effects.  I do notice the irritation and irritability greatly reduced, as is my anxiety over Covid19 and the lockdown isolation   depression is much improved.   I highly recommend this product, and buy it with Relora if nervous snacking or grazing are issues.

**Q: How many mm in each capsule?**
A: Each 2 tablet serving currently contains 300 mg of Magnesium (as magnesium amino acid complex),500 mg GABA (gamma-aminobutyric acid), 450 mg of Taurine, 200 mg of L-Theanine, and 100 mg of Holy Basil Leaf Extract.

**Q: why does the product description say that it contains wheat/gluten but the picture of the bottle label lists wheat and gluten in the "not contained"?**
A: Sounds like a mistake to me.  My bottle says that it contains no wheat.  If I needed to know, I would call the company and ask.  "Phone (800) 815-2333  Monday - Friday 8am - 4:30pm PST"
