Alpha-Lipoic Acid, L-Arginine and B Vitamins: What's in Idrinq and What the Research Says

Idrinq is built around three ingredients instead of caffeine: R(+)-alpha-lipoic acid, L-arginine and a B-vitamin complex. Here's what each one is, what it does in the body, and an honest summary of what research does and doesn't show.

R(+)-alpha-lipoic acid (ALA)

What it is: Lipoic acid is a compound your body makes on its own. Only the R form is made naturally in humans and animals. Many supplements use a 50:50 mix of R and S forms (Linus Pauling Institute, Oregon State University). Idrinq uses the R(+) form.

What it does: R-lipoic acid is an essential cofactor for enzyme complexes in your mitochondria, the parts of your cells that turn food into usable energy. It takes part in key steps of the citric acid cycle.

What the research says: Lipoic acid has been studied mainly as a supplement at doses of 300 to 1,800 mg a day, often for specific health conditions. It is generally well tolerated; the most commonly reported side effects are skin reactions such as rashes and itching, and sometimes nausea. Research in healthy people looking for a direct energy boost is limited.

L-arginine

What it is: An amino acid found in protein foods such as meat, fish, dairy and nuts. People typically get about 4 to 5 grams a day from food (NIH Office of Dietary Supplements).

What it does: Some arginine is converted into nitric oxide, a compound that helps blood vessels widen.

What the research says: We'll be straight with you. A review of 54 studies found that arginine supplements provided little or no improvement in athletic performance, and the NIH describes the evidence for performance and recovery benefits as having little scientific support. Doses up to about 9 grams a day appear to be well tolerated. We include L-arginine as part of Idrinq's patented formula, not as a standalone performance claim.

B vitamins

What they are: A family of vitamins your body uses as coenzymes. For example, vitamin B6 is involved in the metabolism of amino acids, carbohydrates and fats. Most adults need 1.3 mg a day (NIH Office of Dietary Supplements).

What's in a can of Idrinq: Each 12 oz can provides 80–120% of the Daily Value of vitamins B1, B2, B3, B5, B6 and B12, according to the Nutrition Facts label.

What Idrinq is, and isn't

Idrinq isn't a stimulant, so it won't feel like a strong coffee or a typical energy drink. There's no caffeine rush and no caffeine crash. It's a smooth, slightly carbonated drink made with nutrients involved in your body's normal energy metabolism, for people who want an afternoon drink that fits a caffeine-free routine.
