Now Sports Amino Power Pre-Workout Natural Raspberry Flavor
Brand: Now Sports · Form: POWDER [E0162]
Our assessment
The evidence shows that Now Sports Amino Power Pre-Workout contains calcium, which plays a role in muscle function. However, for a pre-workout supplement, this ingredient is not a primary energy or performance booster, and the data on its benefits in this specific context is limited. You should consider whether this product aligns with your specific fitness goals.
How it works
Calcium is a mineral that supports neuromuscular relaxation and nerve signaling, which can be relevant during exercise [NIH ODS]. It also plays a role in bone mineralization, but this is a long-term process and not directly related to acute pre-workout energy [NIH ODS]. Think of it as a supporting player for muscle function rather than a direct energy source.
Safety profile
FDA has received a total of 592,059 adverse event reports for all supplements, but specific report counts for this product or calcium alone are not available in the provided data. High calcium intakes can lead to side effects including constipation, nausea, and abnormal heart rhythms, and may increase the risk of heart disease and prostate cancer [NIH ODS]. Be aware that calcium can reduce the absorption of medications such as tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our assessment: This product is not a standard choice for a pre-workout based on the data provided. If you are looking for a pre-workout for energy and focus, this may not be the best option. If you choose to use it, be mindful of your total calcium intake from other sources and supplements, and space it apart from any medications you take. For specific performance goals, data on this specific product is not available.
