Should men over 30 donate blood for health?
Yes—especially if you’re male and over 30. Iron overload is one of the most overlooked health risks today. Most people are copper deficient and iron overloaded, which damages mitochondria and drives chronic disease. Regular blood donation helps lower ferritin and restore mineral balance. In my own practice and research, I aim to keep ferritin near 30 for optimal function.
Alongside blood donation, I recommend the following foundational supports:
- Liver, bee pollen, and other food-based B vitamins
- ~800 mg magnesium (glycinate, bicarbonate, or malate)
- 500–1000 mg whole vitamin C from amla, acerola, or camu
- Adrenal support with pink salt and potassium
- Cod liver oil (Rosita, Jigsaw Health, Garden of Life) with natural vitamin A
- Copper support (bisglycinate up to 6 mg daily, or Sovereign Silver hydrosol)
This approach aligns with the Root Cause Protocol, which I recommend for those looking to go deeper.
How many nitrates per day do you need for nitric oxide benefits?
For cardiovascular and performance benefits, research shows you need about 400–500 mg of dietary nitrates per day. The challenge is that supplement companies are not allowed to disclose nitrate content on beet juice powders due to a restrictive patent. This leads to confusing labels and marketing claims that mislead consumers.
That’s why at PureClean Performance, we provide a certificate of analysis (CoA) with every jar of PureClean Beet™. Our beets are grown in U.S. high-nitrate soil and average ~3× more nitrate content than leading beet powders, so you get the performance and cardiovascular support you expect.
What makes PureClean supplements different?
It comes down to three things: quality sourcing, full transparency, and mitochondrial focus. All of our products are:
- 100% natural and non-GMO
- Free from common allergens
- Sourced sustainably and ethically, with U.S. origin whenever possible
We don’t cut corners, hide behind marketing claims, or use low-quality raw materials. Instead, every product—from PureClean Beet™ to FundAminos—is designed to optimize nitric oxide, mitochondrial function, and long-term health.
If you need specific product information, contact us directly—we’re always transparent about what’s inside.
