Customer Reviews

As matcha lover, I tried SilkMatcha first, but kept forgetting to take it or leaving it at home. DNJ+ capsules are just so much easier to stay consistent with, and that's why I've stuck with them.

Female, 50s

I wear a continuous glucose monitor, so I can see exactly what's happening. The difference in my readings when I take DNJ+ versus when I don't is striking — it's night and day.

Male, 30s

I replace breakfast with this and mix it with milk. It's simply delicious. Lately, people keep telling me my skin looks better. I think it's this.

Female, 40s

I'd always avoided protein powders because they upset my stomach and tasted artificial. This one does neither, which is why I love it. I was a bit put off by the stevia sweetness at first, but it grew on me after a few tries. I have it after every workout now, and I can genuinely feel a difference in my digestion.

Female, 50s

After a big lunch or a business meal, I used to hit a wall in the afternoon — that heavy, sluggish feeling. Since I started taking DNJ+, it's completely gone.

Male, 30s

I used to get hit with sudden hunger pangs out of nowhere. Since starting DNJ+, that's stopped and my eating feels a lot more balanced now.

Female, 40s

When I have SilkMatcha before a dinner out, I wake up the next morning feeling noticeably lighter.

Female, 30s

I realized my gut health has been improved after using KAIKO Protein, and I'm continuously using this.
