OxiGuard 10 vs. HealthyHeart Support+: What's Actually on the Label
Both are sold as heart supplements. Both cost $59 a bottle. So we read the OxiGuard 10 and HealthyHeart Support+ supplement facts panels line by line.
By the Barton Nutrition Team. HealthyHeart Support+ is formulated by Dr. Scott Saunders. Updated October 5, 2026.
If you've been looking for a heart supplement, you've probably seen OxiGuard 10 from Simple Promise. It's sold as a cardiovascular formula, and it costs the same $59 a bottle as our HealthyHeart Support+. So which one gives your heart more to work with?
We didn't want to answer that with marketing language. So we did the one thing that settles it: we put the two supplement facts panels side by side and read every line.
First, a warning about OxiGuard 10 reviews
Search for OxiGuard 10 reviews and you'll find dozens of articles. Many of them say OxiGuard 10 contains CoQ10, resveratrol, green tea extract, and alpha lipoic acid.
None of those appear on the OxiGuard 10 label posted on its maker's own website.
Our advice for any supplement
Skip the review sites and read the supplement facts panel. That's the only place a company has to tell you what's in the bottle and how much.

What the OxiGuard 10 label tells you
Look at the four largest ingredients in OxiGuard 10: elderberry, echinacea, L-glutamine, and vitamin C. Add zinc and you have the classic lineup of a cold-and-flu-season immune formula.
There's nothing wrong with those ingredients. But they aren't the nutrients your heart muscle and blood vessels are known to rely on. The two heart-related ingredients on the label, garlic and turmeric, come in at 100 mg each.
So if you're buying OxiGuard 10 to support your heart, most of what's in the bottle is immune support.
What HealthyHeart Support+ is built around
Dr. Scott Saunders designed HealthyHeart Support+ around one question: what does the heart actually run on, and what do the blood vessels need to stay relaxed and open?
Your heart beats about 100,000 times a day and never gets a day off. Here's what we give it to work with, and what OxiGuard 10 has in its place.
CoQ10
100 mgA key part of how your cells turn food into energy. The amount in heart tissue drops by about half between age 20 and age 80.*
OxiGuard 10: none
L-Carnitine
1,000 mgCarries fat into the cell's power plants so the heart muscle can burn it for fuel.*
OxiGuard 10: none
Beet Root
500 mgRich in natural nitrates your body turns into nitric oxide, the signal that tells blood vessels to relax and widen.*
OxiGuard 10: none
Magnesium Glycinate
125 mgSupports the normal relaxation of blood vessel walls and a steady heart rhythm, in a gentle, well-absorbed form.*
OxiGuard 10: none
Olive Leaf Extract
200 mgAntioxidant support for blood pressure and cholesterol already in the healthy range.*
OxiGuard 10: none
Ashwagandha
300 mgHelps your body manage everyday stress, which puts its own strain on the cardiovascular system.*
OxiGuard 10: none
Every ingredient is listed with its exact amount, so you or your doctor can see exactly what you're taking.
"But it's four capsules instead of two"
That's true, and it's fair to ask. The reason is simple: 1,000 mg of L-carnitine and 500 mg of beet root take up room. We could have made a two-capsule formula by cutting those amounts. We chose to give your heart the full amount instead.
You take all four with your first meal of the day, so it's still one routine, once a day.
Price
At one bottle, both cost $59. Buy three or six and HealthyHeart Support+ costs less per bottle than OxiGuard 10, and it ships free. Every bottle is backed by our 90-day money-back guarantee.
So for the same money or less, you get six ingredients chosen for the heart, at full amounts, instead of a formula built mostly around immune support.
Bring the label to your doctor
Whichever supplement you're considering, take the label to your next appointment. Your doctor knows your numbers and your medications, and that matters, especially if you take blood pressure medication or a blood thinner. A good supplement is one you and your doctor can read line by line and feel confident about.
That's exactly why we print every amount on our label.
