The Best Creatine HCl Supplement
The best creatine HCl is CON-CRET Creatine HCl Capsules, at $0.33 a capsule. Each holds 750 mg of creatine HCl, its label says to take 1 per 100 lb of body weight, and it is on two testing lists from NSF, an independent lab. Plain monohydrate has far more research behind it; see how the two compare.
Our pick for: Creatine HCl
- A capsule
- $0.33750 mg creatine HCl
- A bottle
- $29.9990 capsules, on Amazon
- Testing list
- NSF Certified for SportAlso NSF/ANSI 173
Why we pick it It is one of two creatine HCl products here on NSF’s lists: NSF/ANSI 173 checks that the label is right and the product is clean, and NSF Certified for Sport also screens for drugs banned in sport. Capsules mean no mixing and no taste.
What you give up A day at the label dose holds less creatine than most studies used. CON-CRET says 750 mg works like 5,000 mg of monohydrate; trials have not settled that.

How much creatine HCl to take
CON-CRET’s label says 1 serving (750 mg) per 100 lb of body weight; the powder makes half servings easy. Most creatine studies used 3 to 5 g of monohydrate a day; matching 5 g of monohydrate takes about 5.6 g of HCl, or 7.5 servings, about $2.50 a day in CON-CRET capsules. At that dose, plain monohydrate costs far less.
| Your weight | Servings a day (label) | Cost a day (CON-CRET capsules) |
|---|---|---|
| 100 lb | 1 | $0.33 |
| 150 lb | 1.5 | $0.50 |
| 200 lb | 2 | $0.67 |
| 250 lb | 2.5 | $0.83 |

Questions people ask
Is creatine HCl better than monohydrate?
Probably not, but the two small trials that compared them disagree, with 10 people per group. In 40 young adults who lifted for 8 weeks, every creatine group beat placebo and HCl did no better than monohydrate (Eghbali 2024). In 40 soccer players over 4 weeks, the HCl and ethyl ester groups both beat monohydrate on jump, sprint and peak power (Duan 2026). See creatine forms compared.
Does creatine HCl cause less bloating?
We found no trial of it. A PubMed search on September 28, 2026 for creatine hydrochloride with stomach, bloating, diarrhea or gastrointestinal returned no study of its side effects. If monohydrate upsets your stomach, take 3 to 5 g once a day with a meal, or split a larger dose, before you switch forms.
Is creatine HCl safe?
Creatine is safe and well tolerated in most healthy adults, a review of studies by the International Society of Sports Nutrition found (Kreider 2017); most of that research used monohydrate. Ask a doctor first if you have kidney disease, are pregnant or breastfeeding, or are under 18.
How we picked
We looked at the creatine HCl products sold on Amazon by the brands ChatGPT names, read each label, and checked each against NSF Certified for Sport, NSF/ANSI 173 and Informed Sport. We picked the product on the most testing lists, then the easiest to take. Want plain monohydrate instead? See the best creatine, or the creatine guide.
