Mega-Size BCAA 1000 Caps combines leucine, isoleucine and valine in capsules. The individual amounts are disclosed, although the forms are unspecified, which limits detailed comparison with other versions.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality20

The three amino acids are named, but their forms are unspecified. Their relative quality therefore cannot be judged confidently.

Ingredient Transparency63

Individual amounts are disclosed, making the amino acid quantities easy to compare. The unspecified forms leave less detail about how they are supplied.

Value For Money63

The serving cost compares favorably for isoleucine, while leucine is more moderate. Valine offers weaker value for its amount, so the value picture varies across the mix.

Customer Satisfaction91

Customer ratings are favorable across a very large review base. That provides extensive feedback on satisfaction without establishing a particular fitness benefit.

Product Focus40

The formula concentrates on three related amino acids. A specific performance benefit cannot be judged confidently from the available information.

79 Performance

The Original Strawberry Kiwi Splash

XTEND
Higher disclosed amounts of all three BCAAs give 3.5 g leucine, 1.75 g isoleucine, and 1.75 g valine, plus glutamine, citrulline malate, and electrolytes, providing stronger standalone coverage than the original. The expanded powder formula adds ingredients beyond the original three-amino-acid focus, which may be unnecessary for someone seeking only BCAAs.
82 Performance

Branched-Chain Amino Acids

NOW Sports
Higher disclosed amounts of all three BCAAs give 1.6 g leucine, 0.65 g isoleucine, and 0.65 g valine, providing stronger standalone coverage than the original. Leucine still sits below a strong standalone muscle-protein trigger, and full directions and excipient details are not supplied.
79 Performance

Branched Chain Amino Acids (Free Form)

Life Extension
Higher disclosed amounts of all three BCAAs give 1.2 g leucine, 0.6 g isoleucine, and 0.6 g valine, providing stronger standalone coverage than the original. The serving remains modest for standalone use, and full directions and excipient details are not supplied.
60 Budget

Daily Amino Acid

21st Century
The lower listed serving cost provides small BCAA amounts within a broad essential-amino-acid blend, making it a more economical choice than the original. All three BCAA amounts are well below meaningful standalone levels, so the apparent serving value overstates practical coverage.
84 Budget

BCAA 3200 mg

Best Naturals
Fewer than three eligible products cost less per serving; among the nearest-priced options, this formula provides 1.6 g leucine, 0.8 g isoleucine, and 0.8 g valine. Leucine still sits below a strong standalone muscle-protein trigger, and full directions and excipient details are not supplied.

3.5 g leucine, 1.75 g isoleucine, and 1.75 g valine, plus glutamine, citrulline malate, and electrolytes combine a stronger supplied dose-and-value balance than the original.

BCAA Plus Branched Chain Amino Acids

Solgar
0.54 g leucine, 0.36 g isoleucine, and 0.3 g valine, plus vitamin B6 offer a practical quality-and-cost tradeoff, although the supplied data do not establish clearly better value than the original. All three BCAA amounts are well below meaningful standalone levels, so the apparent serving value overstates practical coverage.
