The Builder Bar is marketed as a protein-rich supplement designed to support muscle growth and recovery. The product claims to offer balanced nutrition with high protein content, essential vitamins, and minerals for individuals involved in regular physical activities.

2. Ingredient Justification

The primary ingredient in Builder Bar is protein blend, which includes soy protein isolate and whey protein concentrate. These are common in muscle building supplements due to their high biological value and amino acid profile. Soy protein isolate is a complete protein, meaning it contains all nine essential amino acids necessary for human diet. Whey protein concentrate is well known for its muscle recovery benefits due to its quick absorption rate (Phillips, 2011).

3. Recommended Dosage

For whey protein concentrate, the clinically recommended dosage varies, but a common recommendation is 20-25 grams post-workout for muscle synthesis (Stark et al., 2012).

4. Clinical Trial Evidence

Phillips (2011) found that protein intake, particularly from whey, enhances muscle recovery and growth post-exercise. Stark et al. (2012) demonstrated that the ingestion of 20-25 grams of whey protein post-workout significantly enhanced muscle protein synthesis.

5. Brand Transparency and Credibility

The company behind Builder Bar, Clif Bar & Company, has been in business since 1992 and is known for its transparency in listing ingredients. The company's founder and CEO is Gary Erickson. Their website clearly states that they extensively test their products for quality and safety. However, it's unclear if third-party independent testing is conducted.

6. Summary Verdict

Based on the review, Builder Bar appears to be a credible product with scientifically backed ingredients for muscle recovery and growth. The company has a solid reputation and is transparent with their product information. However, consumers should ensure that their total daily protein intake from all sources aligns with their personal health goals and dietary needs. It would also be beneficial for the company to provide information on third-party testing for further assurance of product quality and safety.
