BioPharma Scientific NanoNAC+ Review
NanoNAC+ is a dietary supplement from BioPharma Scientific, listed in the Dietary Supplement Label Database with DSLD ID 318668 and entered on 21 December 2024. The product is sold as 30 capsules and is classified as a capsule supplement form. Its Supplement Facts panel lists a serving size of 1-3 capsules with 30 servings per container. Each serving provides Vitamin C 270 mg (300% Daily Value), as Ascorbic Acid, and N-Acetyl-L-Cysteine 600 mg, for which no Daily Value is established. The other ingredients are Silicon Dioxide and Hypromellose. The label lists the product's dietary claims as Nutrient, All Other, and Structure/Function, with an intended target group of adults aged 18 to 50 years. The directions say to take 1 capsule (600mg NAC) per day with 6 to 8 ounces of water, and that up to 3 capsules (1,800mg NAC) per day may be taken. The label states that the product is manufactured in the U.S.A. at a cGMP and FDA registered processing facility. Marketing text on the label asks what makes nanoNAC+ different and says it may support a healthy lung system and that vitamin C has been added at 3 times the recommended daily intake to boost the immune system. A second panel lists the statements Breathing, Increase immunity, SuperSorb, and Enhanced Delivery, and says the product may support a healthy immune system, respiratory function, and lung health. Precautions say not to use the product if the inner seal is broken or missing, to keep it out of reach of children, and that pregnant or nursing mothers, anyone taking meds, or people before surgery should consult a physician or pharmacist first. The label says to store in a cool, dry place. The FDA disclaimer states that the statements have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure, or prevent any disease. The brand information says the product is researched, developed and distributed by BioPharma Scientific, LLC of Vista, CA.

Study, Trial or Testing Result Summary
Members Only96 human studies · 43 improved
34 of these 96 human studies gave the ingredient by drip, not by mouth.
Most of the evidence for N-acetylcysteine and the liver comes from hospital treatment of serious liver problems, not everyday supplement use. This product gives 600 milligrams per serving, a full dose at the two daily servings members are told to take. In severe alcohol-related hepatitis, adding it to a med treatment improved 28-day survival [1]. In early sudden liver failure not caused by paracetamol, a drip of it improved survival without a transplant [2][3]. It cut liver damage and deaths after paracetamol overdose [4]. Results were not all positive. In children with sudden liver failure it did not help and was linked to lower survival without a transplant [5]. In adults with fatty liver, 2400 milligrams daily by mouth for 12 weeks did not improve liver fat or scarring [6]. Vitamin C is at a full dose here, but its liver evidence is mixed and mostly comes from combinations with other ingredients. It lowered liver iron in thalassemia [7] and, with vitamin E, improved liver scarring in one trial [8]. Vitamin C alone did not change liver enzymes in adults with diabetes [9], and pooled reviews found no clear benefit [10][11]. Animal and cell studies are never counted.

Review Totals and Summary
Members OnlyWhat buyers say
Overall, there is no usable feedback on the NanoNAC+ capsules here. The only reviews supplied describe a powder product that is mixed in a drink, so they cannot tell you how the capsules perform. I left those reviews out because they are about a different form. Each one refers to a scoop, mixing, a flavor or a bottle of powder, not capsules. Writing the themes below from them would misrepresent the capsules. **What buyers say it did for them:** Nothing about the capsules. The reviews that mention results are about the powder, and they do not describe any effect from capsules. No store summary was provided to fill the gap. **What they complain about:** No complaints about the capsules appear. No store summary was provided that mentions any. **Taste, smell, pill size or form:** No capsule feedback on any of these. The comments on taste and texture, such as a green apple flavor and no chalky feel, are about the powder, so they say nothing about swallowing capsules, capsule size or smell. One reviewer says it comes "in one bottle" and another mentions "no stack of pills," but both are in the context of the powder, so I have not treated them as statements about the capsules. **Value for money:** Nothing on price or value for the capsules. None of the reviews raise cost. **Who it suits and who it did not:** Nothing can be said about who the capsules suit. The powder reviewers seem to like a quick routine, either in the morning or as an evening wind-down. That tells you about the powder, not the capsules. **What this means for your decision:** The material gives you no basis to judge the capsules in either direction. To decide, look for reviews on the capsule listing that mention swallowing the capsules, how many you take per serving, and how they sit with you. Check that any review you rely on clearly refers to capsules, because this store page appears to mix in reviews of the powder.
Biohacker Summary
Members Only7 of 10 recommend it
The only ingredient the panel spoke about here is vitamin C, which is a smaller ingredient in this product, and the panel leans toward recommending it. Most of the ten recommend or use it, with several taking it for collagen and skin support, often paired with collagen, and others for immune support, especially at the first sign of a cold. Doses people mention range from 250 milligrams a day to about a gram a day in divided doses, with one saying 2 to 4 grams and another noting that very high doses may not always help. Forms mentioned include food sources, a liquid liposomal version, and topical use on skin, and one person stopped a vitamin C serum because of its smell while another noted that taking it beyond normal levels has not been shown to protect against cataracts.

Ben Greenfield · Vitamin C · recommends
- States that vitamin C is extremely important for collagen turnover and cites orthopedic data showing that 500 mg to 1 g of vitamin C can reduce the rate of complex regional pain in total knee replacements and wrist fractures.
- Mentions vitamin C as part of a bare-minimum protocol.
- Notes that while vitamin C has significant value, the optimal dose is a vexed question, and high doses might not always be beneficial, potentially blunting the hormetic effects of exercise.

Members OnlyBody systems · Combine with · Possible side effects
Body systems: Liver, Digestive system, Immune system
Combine with: For glutathione and liver support, NAC pairs well with glycine (together they form GlyNAC, which supports glutathione synthesis), selenium (a cofactor for glutathione peroxidase), vitamin C and vitamin E for antioxidant recycling, and milk thistle (silymarin) for liver cell protection. Alpha-lipoic acid can also help regenerate glutathione. If the goal is truly improved blood flow, add nitric oxide supporting ingredients such as L-citrulline or L-arginine, beetroot extract, and vitamin C, plus omega-3 fatty acids and CoQ10 for broader vascular health. Consult a healthcare provider before combining supplements, especially if you take meds, nitrates or meds, since NAC and nitric oxide boosters can interact with them.
Possible side effects: No adverse events were reported with vitamin C in the thalassemia trial, and one pooled review found antioxidants including vitamin C may have raised a liver enzyme. No product reviews were available.
