Who should take this supplement, and who should ask a doctor first?

The label is for adults only and is not for pregnant or nursing women. It asks anyone taking medication (especially antihypertensives, anticoagulants or antidiabetic drugs), with a medical condition (especially asthma or renal disease) or planning surgery to consult a physician first, and lists glaucoma, herpes simplex, a previous myocardial infarction and established coronary artery disease as reasons to avoid the product unless a physician prescribes it.

How should the tablets be taken?

Take 1 tablet twice daily as needed, between meals or at bedtime, with at least 8 oz (about 240 ml) of water or juice to aid absorption, as the label directs. Dietary supplements are not medicines, so effects and timing vary with individual diet, lifestyle and body constitution, and there is no fixed onset time.

What warnings come with L-arginine?

L-arginine carries extensive label cautions for adults. The label is not for pregnant or nursing women, and people on medication, with medical conditions, planning surgery, or with glaucoma, herpes simplex or existing heart disease should consult a physician or avoid it as the label directs. This product is a dietary supplement. It is not intended to diagnose, treat, cure or prevent any disease, and it is not a substitute for a balanced diet, medication or professional medical advice. Consult a doctor or pharmacist if you are pregnant, breastfeeding, taking medication, have a medical condition or are preparing for surgery.

How should the bottle be stored, and how many tablets does it hold?

Store the bottle in a cool, dry place after opening, as the label directs. The 120-tablet bottle provides 120 servings of 1 tablet, so at 2 tablets daily it covers about 60 days.

What can this be paired with in a daily routine?

The label says to take each tablet with at least 8 oz of water or juice between meals or at bedtime, so pair it with a full glass of water at those times and note it for a pharmacist to review.
