Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Refer to label instructions
A preliminary trial found that a combination of magnesium and malic acid might lessen muscle pain in people with fibromyalgia.
A preliminary trial found that a combination of magnesium and malic acid might lessen muscle pain in people with fibromyalgia.1 The amounts used in this trial were 300–600 mg of elemental magnesium and 1,200–2,400 mg of malic acid per day, taken for eight weeks. A double-blind trial by the same research group using 300 mg magnesium and 1,200 mg malic acid per day found no reduction in symptoms, however.2 Though these researchers claimed that magnesium and malic acid appeared to have some effect at higher levels (up to 600 mg magnesium and 2,400 mg malic acid), the positive effects were not demonstrated under blinded study conditions. Therefore, the evidence supporting the use of these supplements for people with fibromyalgia remains weak and inconclusive.
How It Works
How to Use It
Healthy people do not need to take malic acid as a supplement. Research has been conducted with 1,200–2,400 mg of malic acid in combination with 300–600 mg of elemental magnesium .
Where to Find It
Malic acid is found in a wide variety of fruits and vegetables, but the richest source is apples, which is why malic acid is sometimes referred to as “apple acid.”
A deficiency in humans is unlikely, since the body can produce malic acid.
