Great!

Have sleeping issues and can't really sleep without supplements. Use these in rotation with other herbs and they work just fine! Buying them not for the first time and they work as they should

Calm-in-a-capsule—steady stress support, no grogginess

I’m impressed with this Holy Basil from Source Naturals. One 450-mg capsule takes the edge off busy days without making me drowsy or foggy. After a week, I noticed smoother mood, fewer “wired but tired” afternoons, and easier wind-down at night. No stomach upset, no jitters—just a gentle calm. Quality feels solid and consistent; the capsules are easy to swallow and there’s only a mild herbal smell. The 120-count bottle is great value and makes daily use simple. What’s worked for me: 1 capsule with breakfast, and on tougher days a second one mid-afternoon. If you’re sensitive, start with 1 daily and see how you feel. Small tip—don’t pair with other sedating herbs at first so you can gauge its effect. Pros: clean formula, reliable calm, non-sedating, excellent price per capsule. Cons: herbal aroma may be strong for some, and effects are gentle (not a quick knockout). Overall, a steady, natural support for stress and busy schedules. As always, check with your healthcare provider if pregnant, nursing, or taking medications (especially for blood sugar or thyroid

This is the greatest Holy Basil I've ever had! I conducted a lot of research on which companies to trust and who to buy from for a pure, quality-controlled product, and Source Natural's quality standards always ranked at the top of several lists. This brand appeals to me since I know I'll get a clean product within the capsule. For all that Holy Basil is recognized for, this Holy Basil is a terrific addition to our supplement list. It's not only good for our health, but it's also a great spiritual booster and improvement. Thank you, Source Naturals, for being such a reliable company!

Good, but may interfere with the thyroid.

I really like Tulsi, but always have to be careful of the dosage I'm taking, as it seems that if I take more than one capsule a day it lowers my body temperature. I only found out by accident that it may actually interfere with thyroid function, and I'm not quite sure what it is doing for me. Brahmi = bacopa monieri is supposed to rather help increase body temperature, and I have taken it to help when I take too much Tulsi.

Calming and grounding

I've used these supplements on a few occassions recently, and they do the trick! I was feeling anxious and took the recommended dose and after about 45 minutes felt a sense of calm which was a huge benefit. I tend to like this brand bc of their high quality ingredients.

One of My Top 2 Adaptogens -- Holy Basil is Underrated!

I've always found Holy Basil relaxing, especially at night. I am always reluctant to take products if I can get them as teas; however, I was thoroughly impressed with the convenience of this product. I noticed improvements in sleep and relaxation, with less overall stress during the day. Overall, great quality supplement by Source Naturals. I would highly recommend!

Tried it for a short while, stress management

I only took this for a short while. Did not feel that it helped me with my stress at this point. Might try it again later
