## Questions & Answers

**Q: will this product replace calis for erectile dysfunctiol ?**
A: It sure has worked for me.  No longer have to take Cialis.  I take 2 pills in the morning, and 2 at night.  Has also lowered my blood pressure 40 points.

**Q: Is this a herb medicine ? i mean is it made out of natural stuff ?**
A: L Arginine is an Amino Acid.  See belowArginine is a conditionally essential amino acid, meaning that whether or not it is required to be healthy is conditional on the health status or life cycle of the individual. The biosynthetic pathway, however, does not produce sufficient arginine, and some must still be consumed through diet.citation neededIndividuals with poor nutrition or certain physical conditions may be advised to increase their intake of foods containing arginine. Arginine is found in a wide variety of foods, including:Animal sourcesdairy products (e.g., cottage cheese, ricotta, milk, yogurt, whey protein drinks), beef, pork (e.g., bacon, ham), gelatin, poultry (e.g. chicken and turkey light meat), wild game (e.g. pheasant, quail), seafood (e.g., halibut, lobster, salmon, shrimp, snails, tuna)Plant sourceswheat germ and flour, lupins, buckwheat, granola, oatmeal, peanuts, nuts (coconut, pecans, cashews, walnuts, almonds, Brazil nuts, hazelnuts, pinenuts), seeds (pumpkin, sesame, sunflower), chickpeas, cooked soybeans, Phalaris canariensis (canaryseed or alpiste)

**Q: How large are the capsules? Are they easy to swallow?**
A: It is a tubular shaped capsule, approximately 7/8" long by 1/4" diameter.  Very smooth and I find swallowing it to be simple.  I typically swallow two at a time.  However, I generally don't have a problem swallowing pills.

**Q: I was taking this supplement as suggested:2 capsules twice a day between meals.
