The Verdict
These two are effectively tied on quality - Nutricost posts an 85 execution score to Sports Research's 85 on our 0-100 scale - but Nutricost is the better value at about $0.21 per dose versus Sports Research's $0.34. Sports Research uses the branded C3 Complex curcuminoids and carries Informed Sport certification; Nutricost uses a 95% extract with an ISO-accredited third-party COA. In our view, if cost is the priority, Nutricost wins; if you want the branded C3 Complex and Informed Sport certification, Sports Research is worth the small premium.

Why This Comparison Matters
Nutricost and Sports Research both pair a 95% curcuminoid turmeric extract with BioPerine (black pepper extract) to boost absorption - the standard value approach to curcumin. Sports Research uses the branded C3 Complex curcuminoids in a coconut oil softgel; Nutricost uses a 95% extract in capsule form at a lower price.
BioPerine meaningfully increases curcumin bioavailability, which is important because plain curcumin is poorly absorbed. Both products take that route, so the comparison is about cost, the specific curcuminoid source, and testing.
We scored both on evidence, quality, cost per effective dose, and transparency.
Detailed Score Breakdown
Nutricost Turmeric Curcumin with BioPerine 2300mg
Nutricost
2300mg per serving (3 capsules of 767mg each) with 95% curcuminoids and BioPerine. Piperine increases curcumin absorption approximately 20-fold. High total curcuminoid load per serving.
GMP certified, ISO-accredited third-party testing for each batch (COA available on website). No NSF/USP certification, but their testing transparency is above average for a budget brand.
$0.21/day at 2300mg (3 capsules) - outstanding value for a high-dose curcuminoid + BioPerine product at 40 servings per bottle
95% curcuminoids stated, BioPerine included, no proprietary blends; does not use a branded curcuminoid ingredient like C3 Complex
High-dose budget option with good testing transparency. The lack of a branded curcuminoid ingredient (like C3 Complex) means the evidence base is less direct, but the 95% standardization and BioPerine inclusion are sound formulation choices.
Turmeric Curcumin C3 Complex with BioPerine 500mg
Sports Research
C3 Complex curcuminoids at 500mg per serving with 5mg BioPerine. C3 Complex is the benchmark formulation in curcumin research - the same raw material used in many published clinical trials.
Informed Sport certified - a credible third-party program that tests for over 200 banned substances and verifies label accuracy. Good certification for athletes; not at the level of NSF Certified for Sport in terms of scope, but a legitimate mark.
$0.34/day at 500mg (1 capsule) - fair pricing for an Informed Sport certified C3 Complex product
C3 Complex identified by name, BioPerine dose disclosed, liquid softgel format noted, no proprietary blends
The coconut oil-based softgel format provides a built-in fat source alongside the piperine, which may further support curcumin absorption. Informed Sport certified makes this a credible choice for competitive athletes.
How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.
