OL Olympian Labs, Inc. Malic Acid With Magnesium

Our assessment

The evidence shows that this product contains two ingredients: malic acid and magnesium. While the label does not specify the exact form or dose of magnesium, the data provided on a related mineral, calcium, offers important context for understanding mineral supplementation generally. For this product specifically, many key data points are simply not available, including the precise magnesium content and the source of malic acid. You should approach this supplement with caution until more specific information is provided by the manufacturer.

How it works

While data on the specific combination of malic acid and magnesium is not available, we can look at the role of minerals like calcium to understand how similar nutrients function. For example, calcium supports bone mineralization by helping deposit minerals into your bone structure, and it plays a role in neuromuscular relaxation, aiding both nerve signaling and muscle function [NIH ODS]. Malic acid is often included in supplements to support energy production at the cellular level, though specific research data on its effects in this product is not provided.

Safety profile

Data not available for the specific side effects of malic acid or magnesium in this product. For context, the FDA has received a total of 592,059 adverse event reports across all dietary supplements, but specific report counts for this product are not listed [FDA data]. Regarding mineral safety generally, high levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS].

Our recommendation

Because the label is marked "See label" and key details like the exact magnesium dosage are missing, our recommendation is to not take this supplement until you can verify the complete ingredient list and amounts from the manufacturer. For general health, you should prioritize getting magnesium from food sources like almonds, spinach, and black beans, and consult your healthcare provider before starting any new supplement, especially if you take medications like bisphosphonates or antibiotics, as calcium can reduce their absorption [NIH ODS].

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
