Gaia Organics Lemon Balm Herb

Our assessment

The evidence shows that Gaia Organics Lemon Balm Herb is a single-ingredient supplement, and we need to be clear: the data we have on the active ingredient is for Calcium, not Lemon Balm. Data for Lemon Balm itself is not available. Our assessment is that you should not use this product to address calcium needs, as the label does not list a calcium content, and the health data we have pertains strictly to the mineral Calcium [NIH ODS].

How it works

If this product were a calcium supplement, it would work through two primary mechanisms: Bone mineralization, where it supports bone density and mineral deposition, and Neuromuscular relaxation, where it supports muscle relaxation and nerve signaling [NIH ODS]. However, because the product is labeled as Lemon Balm Herb and contains no listed calcium, these mechanisms do not apply to this specific product.

Safety profile

Data for the safety profile of Lemon Balm is not available. For context, the FDA has received a total of 592,059 adverse event reports across all dietary supplements [FDA data]. If you were taking a calcium supplement, high levels could cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Additionally, calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation is to not rely on this product for any specific health benefit, as the only supporting data we have is for the mineral Calcium, which is not listed as an ingredient. Data on Lemon Balm is not available. If you are seeking a calcium supplement, choose a product that lists a specific amount of elemental calcium per serving. Always consult your healthcare provider before starting any new supplement, especially if you take prescription medications [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.
