Hard to assess the immediate value of a supplement

[This review was collected as part of a promotion.] Two main thoughts here. Normally in order to make an intelligent review of a supplement, one needs to be on it long enough to see how it makes them feel. This is a big limitation of trying to review something like this within a few weeks of obtaining it. So, let me focus on the brand Best Naturals and on the specifics of Nattokinase. I hadn't heard of the brand Best Naturals when I obtained this product as part of a sampling program. It is very difficult to know the standard of a supplement company, so I usually rely on resources such as Supp.co or Consumerlab.com which are sites that evaluate product quality and pill content. This nattokinase product is free from any artificial colors, flavors, or fillers. My research indicated that Best Naturals products do have some variability when testing the doses promised. Their B vitamins ranked high, but some other formulations didn't contain the promised amounts. This product wasn't tested specifically, but this is considered a less expensive value brand, so take that into mind when considering. As for taking nattokinase, this product seems like it would be a good value. I talked with my cardiologist before considering this product. Natto works as a fermented soybean product that is supposed to help thin the blood, hence improving blood pressure and reducing the risks of clotting. However, if you are taking other prescriptions that rhon the blood, or are taking aspirin, or supplements like ginkgo biloba, be sure you aren't overdoing it with blood thinners and talk to your physician or pharmacist

Vegan

[This review was collected as part of a promotion.] I’ve been trying Best Naturals Nattokinase for a while now. The capsules are easy to swallow and they don’t upset my stomach. I really appreciate the clean formula — non-GMO, gluten-free, and free from common allergens. That gives me peace of mind. After using it regularly, I started to feel lighter and a bit more energetic. I also like that it’s sourced from fermented soy, which feels more natural. 🌱 What I like: • Allergen-free formula • Vegetarian capsules • A big bottle (240 capsules) that lasts a long time So far, I haven’t noticed any negative side effects. I think it’s a good choice for anyone looking for a clean and trustworthy supplement.”

Heart Health

[This review was collected as part of a promotion.] I got the vitamin Nattokinase. It’s a vegetarian capsule good for heart health. It had the ability to break down blood clots. Several of my family members have the factor 5 blood clotting disorder . This vitamin is perfect for them. You take 2 capsules on an empty stomach. The packaging is pretty standard for vitamins- nothing fancy.

Great value for quality potency

[This review was collected as part of a promotion.] I appreciated the opportunity to try Best Naturals High Potency Nattokinase 4000FU/ 200mg. Before starting, I looked up the ideal dosage and this was it (4000FU/ 200mg per Serving). Natto is a fermented soy and is purported to aid in cardiovascular health. Since I’ve only been taking this for two weeks I haven’t noticed the full effects yet, but I’m looking forward to my annual exam and blood tests as I suspect the benefits will be very evident at that time 👍🏼 I rated it 4-stars at this point only because I have not taken it long enough to realize the full benefits yet; once I do, I will update my review accordingly. I liked that this is made in the USA. Also NO artificial colors, flavors, sweeteners, preservatives, GMOs, or common allergens (milk, soy, eggs, corn, gluten, wheat, yeast, fish) aaaaand it’s 3rd-party lab tested for quality and consistency (which shows me they trust their processes). What I like most about this product so far? Only 2 capsules per day! So many supplements require you to take 6-9 capsules per day — who has time for that — so I’m thrilled that Best Naturals created this High Potency formula which consolidates the dosage to only 2capsules per day; and for providing 240 capsules which will last a whopping 40 days. Great value for quality potency.

Great Supplement for Overall Health

[This review was collected as part of a promotion.] I’ve been really impressed with Best Naturals High Potency Nattokinase, a product I received from Influenster for this review. The capsules are easy to take, and I appreciate that they’re free of unnecessary fillers or artificial ingredients. Within a few weeks of consistent use, I’ve noticed a real difference in my overall circulation and energy levels—I feel lighter and more balanced throughout the day. Another thing I like is the peace of mind knowing that Best Naturals holds to high quality standards. The potency is exactly as advertised, and I can tell this supplement is made with care. It’s also gentle on the stomach, which is important for me when taking something daily. Overall, this is a trustworthy and effective supplement. If you’re looking for a natural way to support heart and circulatory health, Best Naturals High Potency Nattokinase is an excellent choice. I’ll definitely be keeping it as part of my wellness routine.
