Exceptional purity and safety
This agricultural-grade magnesium sulfate heptahydrate (MgSO4•7H2O) is an extremely soluble and bioavailable source of magnesium and sulfur for the health of animals and plants.
For plants:
- Contains essential plant nutrients: magnesium and sulfur
- Optimum solubility needed to make true clear solutions and compatible with other soluble nutrients
- Ideal source for all Fertigation Systems: center pivot, micro-jet, drip-trickle and foliar spray applications
- Magnesium is critical as a central element in the chlorophyll molecule to capture energy from the sun and convert it to plant sugars via photosynthesis
- Magnesium is especially required in sandy soils, soils with low CEC, for crops with high Mg demand and in situations of high applications of ammonium-N and/or potassium
For animals:
- Contains macro-nutrient magnesium and secondary nutrient sulfur
- Excellent solubility means greater animal bioavailability than other magnesium sources
- Effective magnesium for the prevention and treatment of hypermagnesemia and grass tetany, especially in early lactating dairy cows
- Effective magnesium nutrition in non-ruminant feeds; also used for enhanced mobility, reduced discomfort and a beneficial calming effect
- Magnesium is an important cofactor in enzymatic reactions vital to every metabolic pathway in every animal species

Five stars for BOKA without hesitation.
Size: Pack of 1, 4 Ounce, Set name: A. Ela Mint
I have tried a lot of natural toothpastes over the years and I can honestly say that Boka completely surprised me in the best possible way. From the very first use it felt like I had finally found a toothpaste that balances modern science with a clean ingredient philosophy. You will not be disappointed.
The standout ingredient here is nano hydroxyapatite, which is the same mineral that naturally makes up tooth enamel. That immediately caught my attention because instead of simply masking dental issues it actually supports remineralization. After learning more about nano hydroxyapatite and how it interacts with enamel I felt confident giving this toothpaste a real trial. The texture is smooth and creamy and it spreads easily across the teeth. Some fluoride free toothpastes can feel chalky or thin but this one feels refined and well formulated. It produces a gentle foam that feels pleasant while brushing but never overwhelming.
The flavor is another area where this toothpaste shines. It is refreshing without being harsh or overly minty. My mouth feels clean and balanced after brushing rather than blasted with artificial intensity. That subtle freshness actually lasts much longer than I expected.
After about two weeks of consistent use I started noticing that my teeth felt smoother throughout the day. That polished feeling you normally get right after a dental cleaning lasted longer than usual. My teeth also appeared brighter which was a welcome bonus.
Another thing I appreciate is the ingredient transparency. There are no questionable additives and it is completely fluoride free which is important for people who prefer alternatives that still support enamel health. Knowing that nano hydroxyapatite is widely used in advanced dental care products in other parts of the world made this even more compelling.
The packaging is clean and modern and the tube dispenses easily without making a mess on the cap. It feels like a premium product from start to finish. What really impressed me is how well this toothpaste balances effectiveness, comfort, and thoughtful formulation. It manages to feel gentle while still leaving my teeth incredibly clean and refreshed. If you are looking for a high quality fluoride free toothpaste that focuses on enamel support and a healthier approach to oral care then I highly recommend giving this one a try. It has absolutely earned a permanent place in my daily routine and it is one of the few natural toothpastes I genuinely look forward to using every day.

Great toothpaste.
Size: Pack of 1, 4 Ounce, Set name: B. Whitening
This is by far really great toothpaste. I can tell the difference in the color of my teeth. And sometimes my teeth are kinda sensitive to harsh toothpaste. But this is good for sensitive teeth. And minty flavor is not to strong either. Try it. I hope it works for you as well as It does for me. 🤗

It leaves my mouth feeling fresh for hours, and since it’s SLS-free, it doesn’t cause any irritation or dryness. The texture is creamy, and it foams just enough to feel effective without being harsh. it’s made with natural ingredients, which gives me peace of mind about using it daily. The packaging feels clean and modern, and the 4.2oz size is perfect for travel or keeping on the counter.
