Advanced Red Yeast Rice With CoQ10 Supplement For Women and Men - Our product takes Coenzyme Q10 200mg and Red Rice Yeast and combines them with an Omega 3 Supplement and Magnesium Supplement that also contains Magnesium Oxide and Magnesium Citrate and the results are amazing. Normal Q10 Coenzyme contain smaller dosages like coq10 100mg, red yeast rice 1200 mg. capsules with coq10, or coenzyme q10 100mg. However, Clean Nutra has officially created an even more potent all in one supplement.

The All In One CoQ10 200 mg and Red Yeast Rice Supplement You've Been Looking For - Clean Nutra CardioGuard provides 8 full-dose products in one complex containing a full CoQ 10, Red Rice Yeast Supplement, Omega 3 Fatty Acid Supplements, Magnesium Capsules, Niacin, Zinc, and Vitamin K2 D3 in a convenient 2 capsule dosage. Finally, a stronger supplement than red yeast rice 600 mg. capsules, and omega 3 1000mg have been packed into one convenient solution.

Introducing the CardioGuard All In One Supplement - In addition to containing the equivalent milligram dosage of coq10 200mg softgels, our formula also contains a whopping equivalent of a 3000mg red yeast rice extract supplement. This is a powerful alternative to omega 3 fish oil, coq10 100mg softgels, coq10 gummies, fish oil 1200 mg 360 mg omega-3, and a epa dha omega 3 supplement. Not your typical dha epa omega 3 supplement made with awful tasting omega-3 fish oil.

A Powerful Red Rice Yeast with CoQ10 Supplement - CardioGuard is overflowing with potent omega 3 fatty acids and more such as Vitamin K2 MK7, Vitamin D3 5000 IU, Vitamin B3 (Niacin), and a Zinc Blend as Zinc Citrate and Zinc Gluconate. Clear out the countless coq10 100 mg and lesser supplements and replace it with just one inclusive supplement from Clean Nutraceuticals.

Vetted and Trusted Ingredients - We pride ourselves in offering a quality supplement that combines the benefits of coq10 powder, omega 3 gummies for adults, omega 3 dha and more. Our formulas are proudly made in the USA in a registered and certified facility. Many products offer only a few ingredients like omega 3 fish oil 1000mg capsules and omega 3 fish oil gummies. However, this all-in-one contains much more and not unneeded preservatives or fillers.
