Santa Cruz Nutritionals Fiber Advance Gummies

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and muscle function. However, the data on calcium supplementation carries important safety considerations you need to be aware of. We cannot verify the specific dose of calcium in these gummies as the ingredient amount is listed as "See label," so you must check the label carefully before taking them [NIH ODS].

How it works

Think of calcium as a building block and a signaler. It supports bone mineralization by helping deposit minerals into your skeleton, and it plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

FDA has received 592,059 total adverse event reports across all supplements, but specific data for this product is not available. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

If you choose to take this product, first check the label for the exact calcium dose. Start low and do not exceed the recommended daily intake without consulting your doctor. If you take any medications listed above, take your calcium supplement at least two hours apart from them [NIH ODS]. Given the potential risks at high intakes, we recommend getting your calcium needs from food first and using supplements only to fill a verified gap.

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.
