Life Time Fitness Amino Complex Berry

Our assessment

The evidence shows that Life Time Fitness Amino Complex Berry contains calcium, a mineral essential for bone health, but the specific amount per serving is not provided in the data. Our assessment: without a precise dosage, we cannot confirm the product provides a meaningful or safe level of this nutrient. You should check the label for the exact calcium content before using it as a supplement.

How it works

Calcium acts as a master regulator for your bones and muscles. It supports bone mineralization and density, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the key building block that keeps your skeleton strong and your muscles able to relax properly after contracting.

Safety profile

FDA received 592,059 total adverse event reports across all supplements, but the specific number for this product is not available. High calcium intakes from any source might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects of excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Without the exact calcium dose on the product label, we cannot recommend this supplement for calcium purposes. If you need calcium, check the label first. For most adults, the RDA is 1,000 mg daily from food and supplements combined, but do not exceed the tolerable upper limit of 2,500 mg daily from all sources [NIH ODS]. Always take calcium supplements with food and separate them from thyroid medication or antibiotics by at least 4 hours [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.
