Sports Research Turmeric Curcumin

This softgel from Sports Research Corporation — a family-founded manufacturer running out of San Pedro, California since 1980 — packs 500 mg of turmeric extract per capsule, standardized so that 475 mg of it is curcuminoids at a 95% concentration. It's carried in virgin coconut oil and paired with 5 mg of BioPerine, the company's branded black pepper extract, delivering roughly 4.75 mg of piperine per dose. Labeled use is one softgel, taken with food, one to three times a day.

Why the piperine matters, and what's missing

Curcumin has a well-documented weakness: taken alone, very little of it actually makes it into the bloodstream. Piperine is among the more established compounds used to counter that absorption problem, and naming both the ingredient and its exact dose is a meaningfully more transparent approach than the vague "absorption-enhancing blend" language common in this category. That said, the listing itself doesn't point to a specific trial testing this formulation's own absorption numbers — the case for pairing curcumin with piperine rests on general pharmacological reasoning rather than a study citation tied to this exact product.

Certification, plainly stated

The product carries Igen Non-GMO Tested certification. It does not carry NSF, USP, or Informed Sport certification, and we'd rather say that plainly than let a reader assume a testing tier that isn't there.

Safety notes

Curcumin carries a mild blood-thinning property and can raise bleeding risk when combined with anticoagulant medication, so anyone on blood thinners should check with a doctor first. It's also generally best avoided by people with gallstones or a bile duct obstruction, since curcumin stimulates bile and gallbladder contraction. If surgery is scheduled, the standard guidance is to stop turmeric supplements roughly two weeks ahead of time.

Why Grade B

The disclosure here is genuinely good: a standardized curcuminoid percentage, a named absorption ingredient at a stated dose, and no disease-cure language anywhere on the listing. That combination is enough to clear our bar for linking to it. It stops short of an A because the absorption reasoning isn't backed by a citation specific to this product, and curcumin's broader evidence base for the things people commonly take it for remains, on the whole, an active area of modest and mixed research rather than settled science.

Given the standardization disclosure, the dosed absorption ingredient, and the absence of overreaching claims, we're comfortable linking to this one. As with any pick on this site, we link to authorized retailers and may earn a commission at no extra cost to you: see the current listing on Amazon.
