Barlean's Forti-Flax

Our assessment

The evidence shows that Forti-Flax contains calcium, and we have specific data on this ingredient. For bone health and nerve function, calcium is essential, but the product’s overall formulation data is not available beyond this single ingredient [NIH ODS].

How it works

Think of calcium as a structural builder and signal messenger. It supports bone density and mineral deposition, and it helps your muscles relax and nerves signal properly [NIH ODS].

Safety profile

Data not available for this specific product’s side effect reports. However, for calcium, FDA has received a total of 592,059 adverse event reports across all supplements. High calcium intakes might increase the risk of heart disease and prostate cancer, and can cause constipation, nausea, weight loss, and abnormal heart rhythms [FDA data] [NIH ODS].

Our recommendation

Because we lack specific data on the full ingredient list and dosages for Forti-Flax, our recommendation is limited. If you choose to take this product, be aware of calcium's potential interactions with medications like tetracycline antibiotics and levothyroxine, and do not exceed the RDA without medical supervision [NIH ODS].

• 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).
