Leafy greens, beetroot, arugula, spinach and celery are all vegetables known to be high in dietary nitrates. However, nutrient density of the soil across the country makes it difficult to predict exactly how much of these greens are required daily to provide a clinically effective dose of Nitric Oxide. In our experience, it requires more leafy greens than most people over 35 are willing to consume every day.

Yes, Berkeley Life is generally safe for individuals with oxalate sensitivities. While oxalate sensitivity affects a small percentage of people (~2%) due to genetic factors limiting their ability to break down oxalates, many can still tolerate small amounts of oxalates with good digestion practices, such as chewing thoroughly, staying hydrated, and possibly using digestive enzyme supplements. The oxalate content in Berkeley Life’s formula is extremely low—only 0.7 mg per dose, which is less than the oxalates found in a single leaf of spinach. While beetroot is a key ingredient in Berkeley Life for its dietary nitrate content, the amount is not enough to significantly affect even those with oxalate sensitivities For those managing oxalate sensitivity or kidney stones, it’s important to focus on digestive health and reduce processed foods, sugars, and alcohol rather than strictly eliminating foods or supplements like Berkeley Life. Berkeley Life’s Nitric Oxide Test Strips can also be used to monitor nitric oxide levels and ensure efficacy.

As with all supplements, everyone will feel a difference at different speeds. There are some who notice a difference right away, and others see benefits after using the product for about a month. However, unlike most supplements you can validate that our N.O. supplements are working by using our patented Nitric Oxide Test Strip before and 90 minutes after you take the supplement.

Berkeley Life is safe, well-tolerated, and has no counter-indications for medications. As always, if you are uncertain work with your healthcare provider to determine the appropriate combination of medicine and supplementation that's right for you.
