Nitro Wood is a dietary supplement used to support circulation which is sold by a brand called Inno Supps. The brand suggests the supplement may also improve sex, stating that it can “Unleash Your Sexual Power” because “more blood to your bits could mean better stimulation to your love organ.”
But does Nitro Wood contain research-backed ingredients for improving circulation and sex drive, or are these just marketing claims? Does it contain any harmful additive ingredients? And how do real users rate and describe the effects of this supplement?
In this article we’ll answer all of these questions and more as we review the ingredients in Nitro Wood based on clinical studies to give our take on whether the supplement is likely to be effective or if it’s a waste of money.
We’ll also share real, unsponsored user reviews of Nitro Wood.
Ingredient Analysis
Nitro Wood contains a large number of active ingredients.
Niacin, also known as vitamin B3, is effective for improving circulation but may be underdosed in Nitro Wood at only 10 milligrams (mg) per serving. A clinical trial published in the British Journal of Ophthalmology found that niacin improved blood flow, but the doses used were 250 mg and 500 mg.
We can’t find any clinical studies proving that niacin at only 10 mg improves blood flow, nor does Inno Supps cite any.
Vitamin C was shown in a clinical trial to improve circulation but the dose used was nearly 10x the dose in this supplement.
The remaining active ingredients in Nitro Wood are contained in a “Blood Circulation Blend.”
Maritime pine bark extract was shown in a 2011 medical review to improve cardiovascular function, and the doses used in some of the analyzed trials were similar to the dose in Nitro Wood.
Beet root powder is proven to reduce blood pressure, but at a dose far higher than what’s included in these pills. As we documented in our review of a supplement called Superbeets, the only clinical trial we could locate on beet powder for blood pressure reduction used a dose of 10 grams (g), or 50x the amount in Nitro Wood.
Grape seed extract was shown in a clinical trial to reduce blood pressure at a dose similar to that in Nitro Wood.
S7 is a blend of plant-based ingredients whose manufacturer claims it can increase nitric oxide levels by 230%. Nitric oxide widens blood vessels and can reduce blood pressure. However, the manufacturer provides no proof of such claim and simply states to “contact us” for clinical trial results.
Overall we consider Nitro Wood to be a high-quality supplement given that it contains a number of research-backed ingredients, and is free of any harmful active or inactive ingredients. We consider this supplement likely to improve cardiovascular function, in particular due to the effective doses of maritime pine bark extract and grape seed extract.
We can’t locate much clinical evidence suggesting that this supplement will directly improve male sexual function or erection quality, but improvements to cardiovascular health and blood pressure should have favorable downstream effects on those outcomes.
